[since leishmaniasis is an obligatory intracellular parasite, host defenses
are dependent on T-lymphocyte activity. T-lymphocyte regions, in the lymphoid
organs, become depleted, and B-cells proliferate in response to infection.
Without T-cell support, macrophages cannot kill the amastigotes, and the
parasite proliferates. Proliferation of B-lymphocytes, histocytes, and
macrophages results in lymphadoneopathy and hepatosplenomegaly. Exuberant
B-lymphocytes generate a large number of circulating immune complexes (CIC),
which deposit on the walls of blood vessels causing vasculitis, polyarthritis
and glomerulonephritis. In canines, CIC deposition in the kidneys results
in renal failure, which is the main cause of death in leishmania-infected
dogs. Cats are rarely clinically affected. The primary clinical findings
are cutaneous involvement, although dermatologic abnormalities, in the
absence of other signs of disease, are rare. Weight loss, and muscle atrophy,
are the most common signs of visceral involvement. Diagnosis is based on
finding amastigotes free, or in macrophages, in giemsa-stained smears from
lymph nodes or bone marrow. Biopsy material from liver or skin is also
useful, as is serologic testing (IFA, CF, ELISA). Serology is often used
to verify the presence of antibodies but does not prove, or disprove, active
disease. Since dogs rarely spontaneously eliminate the parasite, a positive
titer should indicate current infection. Canine leishmaniasis is resistant
to therapy. Most clinicians feel that the dog never will eliminate the
infection, and that re-treatment will be necessary. The drugs of choice
are pentavalent antimonials. It should be remembered that leishmaniasis
is zoonotic and a public health concern, and care should be taken in both
handling and treating canine cases. All in all, treatment is generally
not recommended, usually unrewarding, and can take a toll on the animal]
influenzavirus
A (H3N8)
closely related to an equine flu strain is spreading in kennels and at
dog tracks around USA. The virus has killed racing greyhounds in 7 states
(Florida, Massachusetts, Arizona, West Virginia, Wisconsin, Texas, and
Iowa) and has been found in shelters and pet shops in many places, including
the New York suburbs, though the extent of its spread is unknown. The virus
spread most easily where dogs were housed together but that it could also
be passed on the street, in dog runs, or even by a human transferring it
from one dog to another. Kennel workers have carried the virus home with
them. In January 2004 at a racetrack in Jacksonville, Fla., 8 of the 24
greyhounds who contracted the virus died. Because dogs had no natural immunity
to the virus, virtually every animal exposed would be infected. Only approximately
10% of dogs are affected, and those are primarily greyhounds. About 80%
of dogs that are infected with the virus will develop symptoms. The symptoms
were often mistaken for those of kennel cough
: both diseases can cause coughing and gagging for up to 3 weeks, but dogs
with canine flu may spike fevers as high as 106°F and have runny noses.
A few will develop pneumonia, and some of those cases will be fatal. Antibiotics
and fluid cut the pneumonia fatality rate. There were no known cases of
the canine flu infecting humans. There is currently no vaccine for the
canine flu. But one would be relatively easy to develop. The canine flu
is less lethal than parvovirus, which typically kills puppies but can be
prevented by routine vaccination. Laboratory tests have shown that the
new flu is susceptible to amantadine and oseltamivir, but those drugs are
not licensed for use in dogs. Tracks and kennels have been forced to shut
down for weeks for disinfection. In Chestnut Ridge, north of New York City,
about 88 dogs became sick by early September 2005, and 15% of those required
hospitalization. The kennel was vacated for decontamination by 17 Sep.
About 17 of the infected dogs were treated at the Oradell Animal Hospital
in Paramus NJ, where one died and 2 more were still hospitalized. The Best
Friends chain owns 41 other kennels in 18 states, and no others have had
an outbreak. In late July 2005, at Gracelane Kennels in Ossining NY, about
35 dogs showed symptomsref1,
ref2.
Since the dog flu virus is just emerging, dogs have no natural immunity
to it : all dogs exposed will become infected, and roughly 80% of infected
dogs will develop symptoms of the illness. About 5-8% of all infected dogs
will dieref.
To date, antibodies to canine influenza virus have been detected in dogs
in animal shelters, adoption groups, pet stores, boarding kennels and veterinary
clinics in 19 states. Since November 2005, scientists have tested > 100
samples from dogs suspected of having canine influenza. All of the samples
turned out to be negative until 23 Feb 2006, when the first of the 3 positive
samples was diagnosed. That first case involved a fatal outbreak of disease
in a Colorado animal shelter. It was followed by a case in San Francisco,
in which an imported puppy became ill but recovered, as did its household-mates.
The 3rd case involved a fatal outbreak in a Florida animal shelterref.
Giardia intestinalis
(2.4-7.3%; prevalence in North America is 8-50%, especially in puppies
in shelters, kennels and pet stores. Most infections are subclinical or
show only transient softening of the stool early in the infection, although
diarrhea may be acute and short-lived, chronic, or intermittent in dogs
and cats. Treatment for Giardia includes bathing the infected animal
and decontamination of the animal¹s environment with a quarternary
ammonium-based disinfectant. Drugs that may be used include metronidazole,
albendazole, fenbendazole, and quanacrine. GiardiaVax is a commercial Giardia

virus
(since 2002 to August 2003 there have been 6 cases of rabies recorded in
domestic dogs in Western Europe (France and Switzerland). 5 of the cases,
including the current one, involved unvaccinated puppies (the ages were:
a few weeks; 2.5 months; 3 months; 4 months; and 6 months), all illegally
imported from North Africa. One case involved a ot-properly-vaccinated
4-year-old dog returning from North Africa to France. Rabies in puppies
is particularly risky, since the clinical signs might be less prominent/typical,
and, because of the higher risk of incidental human exposure, particularly
of children. The last case of classical rabies acquired in UK happened
in 1902. Very occasionally, cases occurring since then have all been acquired
abroad, usually through dog bites. Transmission is usually through saliva
via the bite of an infected animal. There are no documented cases of human-to-human
transmission. Since 1946, there have been 22 deaths in the UK from rabies
acquired abroad)
exposed vaccinated animals should be booster-vaccinated within 5
days of exposure. A 10-day quarantine would apply to an animal that is
vaccinated that bites a person or unvaccinated animal; if signs develop,
it should be destroyed and tested for rabies
unvaccinated exposed animals may be immediately vaccinated and should
be quarantined 6 months and destroyed if they develop signs or vaccinated
before release
In either case, should the animal show signs consistent with rabies, euthanasia
is in order. Most cases in dogs develop within 21-80 days after exposure,
but the incubation period may be shorter or considerably longer.
wobbler syndrome / wobbles : in large to giant dogs, malformation
of the lower cervical vertebrae with compression of the spinal cord so
that the animal has ataxia of the hind limbs and a swaying gait; it may
progress to paralysis
canine
parvovirus disease : an acute, often fatal gastroenteritis of dogs
caused by a parvovirus related to the virus of feline panleukopenia or
of mink enteritis. Parvovirus can be difficult and unrewarding to treat.
It is very hard on the animal. The lining of the gastrointestinal tract
is denuded and absorption of nutrients is impossible. Consequently the
dogs must be nutritionally supported as well as receiving copious intravenous
fluids to keep them hydrated. Antibiotics are often used to keep down secondary
bacterial invaders, although they do not affect the virus. The virus is
very hardy and can be easily transmitted. Virkon-S does kill the virus
in kennels and on solid objects. Maternal antibody to parvovirus from vaccinated
mothers persists up to 16 weeks. Our vaccination regimen recommendation
in practice is based on a minimum of triple antigen (C3 or DHP -- depending
upon your terminology). On the basis of the range of colostral protection
from bitches of variable vaccination status, vaccine manufacturers arrived
at the commercial rationale of vaccination at 6-8, 12-14, and 16-18 weeks
for primary cover. Failure to advise owners about the 3rd primary booster
here is considered negligent (as pups from recently vaccinated bitches
would be more likely to be completely susceptible to parvovirus).
Schiff-Sherrington syndrome : paraplegia in dogs with rigid extension
of the hind limbs, usually associated with acute severe compression of
the thoracolumbar spinal cord.
hypertrophic osteopathy / acropachia : a condition in dogs similar
to the hypertrophic pulmonary osteoarthropathy of humans; characteristics
include hyperostosis of the limbs and later other skeletal regions, sometimes
associated with tumors, tuberculosis, or other pulmonary conditions
canine transmissible
venereal tumor (CTVT) / Sticker's sarcoma is primarily a tumor of adult
dogs that is transmitted by sex and has a high incidence of spontaneous
regression. It has been traced back to its probable origins: a single wolf
or dog that lived in Asia > 200 years ago. The disease seems to have been
more aggressive in its past. This is unusual — most cancers become worse
over time. If we could work out how and why the disease became less deadly,
it may help in finding cancer treatments. Most cancers are formed
when an organism's own cells grow out of control. But canine
transmissible venereal tumor (CTVT) is spread by tumor cells that move
from dog to dog during sex. The disease attacks the face and genitals,
but usually clears up within months. Researchers have suspected that the
diseased cells originated in a single animal. The cancer now affects dogs
in Japan, the USA, Europe, China, the Far East, the Middle East and parts
of Africa. The DNA of tumor cells from 16 unrelated dogs being treated
for CTVT in Italy, India and Kenya. The tumor didn't belong to the dog
because it's genetically different from its host. To find out where the
tumours came from, the team analysed more than 400 dogs from 85 different
breeds. The cancer's DNA was most similar to modern wolves. There was also
a link to Asian dogs such as shitzus. To calculate when the tumour parted
ways from its original host, the researchers counted the genetic differences
between wolf and cancer. The tumour turns out to be at least 200 years
old. If it is any older than 250 years than it's the oldest cancer known
to mankind. Examination of dog cancers from the past 30 years, which were
frozen and collected from 7 different countries, showed that the tumour
was once much more aggressive. If we can work out how this happened, we
might be able to cause the same transformation in human tumours. When the
current version of CTVT infects a new dog, it secretes a chemical that
inhibits the immune system, so that the host cannot fight it off. But after
a few months, the dog's immune system can usually oust the intruderref

Although aflatoxin
has been associated with cancer in people, it does NOT cause cancer in
dogs. Dogs do not live long enough to develop any kind of cancer that may
be associated with aflatoxin. Dogs are sensitive to low-level long-term
intake. Sensitivity to aflatoxins depends on a dog's individual susceptibility,
age, pregnancy status, and nutritional status. Signs in an affected dog
may include bloody vomiting or diarrhea, general lethargy and loss of appetite,
increased water consumption and urination as well as jaundice or yellowing
of the whites of the eyes or gums. In severe cases, aflatoxin can cause
death. Before Dec 1, 2005 Diamond
Pet Food discovered aflatoxin in pet food products manufactured at
its facility in Gaston, South Carolina. Products made at the Gaston facility
are shipped to Alabama, Connecticut, Delaware, Florida, Georgia, Kentucky,
Maine, Maryland, Massachusetts, Mississippi, New Hampshire, New Jersey,
New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina,
Tennessee, West Virginia, Vermont and Virginia. 5 cat food products and
14 dog food products were recalled. The 22 states' veterinarian's offices
reported a total of 17 deaths and 24 illnesses believed linked to the tainted
pet food. Perhaps the reason for this public notice it not for the protection
of dogs but of humans. It is common knowledge that people will eat canned
dog food since it is cheaper than other protein sources and yet it is prepared
under similar FDA regulations as for human foods. According to 16 Feb 2006
information from the Teaching Veterinary Hospital in Israel, 42 dogs have
been hospitalised there so far, all showing typical clinical and clinico-pathological
signs of aflatoxin poisoning. 23 of them have died, 6 recovered and released,
13 remain hospitalised. The number of pet dogs in Israel is estimated to
exceed 200,000. According to official state regulations, dog owners are
required to identify their dogs by approved electronic chips. At present,
> 144,000 electronically identifiable dogs are included in the Central
Dog Registry, maintained by the State Veterinary Services. Diamond is unaware
of any recall food making its way into distribution channels, except in
Israel.
Taenia
crassiceps : a species infecting foxes in Alaska and Canada, found
in rodents as an intermediate host.
Felidae : Bacillus
anthracis
is not common in African wild felidae, where it is more often reported
in lions than leopards. In big cats the lesions are usually oro-pharyngeal
-- and lethal. Infected hides are much more common from cows and sheep,
because when these animals die or are found dead, the only part that can
be harvested is the hide, with the wool or hair of course. This is why
the disease is associated with tanneries, especially when the tannery is
processing imported hides. Zheng He's trading expeditions to East Africa
in the early 15th century may have been how anthrax reached eastern China,
specifically the Sterne-Ames group of organisms, which are otherwise found
in Natal. The Chinese were fascinated by African wild animals. He
even managed to present a live young giraffe to his emperor. Logically
the Chinese merchants and traders would have purchased hides
Felis
catus (cat) : Yersinia
pestis
(when sylvatic outbreaks occur in rodent populations, domestic cats can
become infected through bites of fleas on the rodents, but most acquire
plague through ingesting plague-infected squirrels or other rodents. The
incubation period in cats may be short, a day or 2, and marked by a fever
of up to 41.5°C, lymphadenopathy, lethargy, and anorexia. All 3 forms
-- bubonic, septicemic, and pneumonic -- usually have all 3 of these signs,
and the bubonic form has enlarged lymph nodes as well (buboes; lymphadenopathy;
lymphadenitis), especially in the submandibular lymph nodes. Some of these
may abscess. Typical buboes often occur in the head and neck, and can be
mistaken for cat fight abscesses. Both the bubonic and septicemic forms
may also become pneumonic in cats, and this increases the risk of spread
to humans. There may occasionally be oral lesions or coughing. The following
samples should be taken and forwarded to the relevant diagnostic laboratory:
lymph node aspirate in sterile tube with saline, whole blood (red top tube);
if necropsy: liver, spleen, LN biopsy, lung (fresh and formalin). Bubonic
plague is of zoonotic concern, as individuals may contract disease from
either infected fleas or contact with purulent discharges or blood from
the cat. An even greater threat occurs when the disease in cats progresses
to pneumonic plague. This has been documented in cats, including transmission
to veterinarians and owners. Antibiotic treatment is effective in cats,
but the threat of plague is only one of many reasons that people should
keep their pets free of fleas), Leptospira
interrogans,
pseudorabies
virus (PrV) / Aujeszky's disease virus (ADV) / suid herpesvirus 1
influenzavirus
A(H5N1)
( The first time that this happened, and was reported, was in December
2003 when a few large cats (leopards and tigers) died in a zoo in Thailand
after being fed with infected poultryref.
The second natural event was a much larger H5N1 outbreak
in zoo tigers, also in Thailand, which had been fed chicken carcasses.
Over 140 tigers died, or were euthanised, and there was
convincing evidence of tiger to tiger transmissionref1,
ref2.
Experimentally, it has been shown that domestic cats can be infected with
H5N1 through eating infected material and that these
infected cats can transmit influenza to other cats. These experimentally
infected cats, though limited in number, all became seriously ill when
infected and did not seem to shed the virus until they had symptomsref.
To date the only domestic cats that have been conclusively shown to be
infected have been those found ill or dead in the intense epizootic of
H5N1 in wild birds on Rugen island in Germany in
February 2006ref1,
ref2.
There have been anecdotal reports of increased mortality in cats during
H5N1 outbreaks in other countries (China, Iraq and
Indonesia) but these have not been confirmed by laboratory testsref.
Unconfirmed reports of infections and deaths from H5N1
in cats elsewhere should always be interpreted cautiously. A recent preliminary
report of infected cats in Austria was eventually not confirmed. Reports
of positive serology for H5N1 infection in non-bird
species should be treated with particular caution, especially if these
involve healthy animals and there has been no actual evidence of H5N1
virus (PCR or viral isolation). Serology for H5N1
may be helpful but it needs to be undertaken in laboratories used to handling
H5N1 serology and able to exclude the cross-reactions
that can occur with H5N1ref.
So what should be the recommended actions for cat owners when H5N1
is reported in wild birds, and what is the risk to humans? The Food and
Agriculture Organization has produced guidance. The difficult decision
is when to apply this guidance. This would be highly recommended and reasonable
guidance concerning a poultry outbreak or in an intense epizoonotic such
as on Rugen Island. However, the actions would probably be considered unreasonable
and over-cautious where there have perhaps been just one or 2 birds infected.
Veterinary authorities in European Union countries have not always tried
to enforce guidance like this in the latter circumstances. Also, as cat
owners have pointed out, there are practical difficulties for some of the
guidance -- like trying to keep cats in houses. FAO Recommended Actions
in Areas where H5N1 HPAI has been diagnosed or is
suspected in poultry or wild birdsref:
report any evidence of significant bird mortality (both wild and domestic)
to the local veterinary authority
be especially vigilant for any dead or sick cats and report such findings
to the local vet
make sure contact between cats and wild birds or poultry (or their faeces)
is avoided and/or keep cats inside
if cats bring a sick or dead bird inside the house, put on plastic gloves
and dispense of the bird in plastic bags for collection by local veterinary
animal handlers
keep stray cats outside the house and avoid contact with them
if cats show breathing problems or nasal discharge, a veterinarian should
be consulted
do not touch or handle any sick-looking or dead cat (or other animal) and
report to the authorities
wash hands with water and soap regularly and especially after handling
animals and cleaning their litter boxes or coming in contact with faeces
or saliva
dogs can only be taken outside the premises if kept restrained
do not feed any water birds
disinfect (e.g. with bleach 2-3%) cages or other hardware with which sick
animals have been transported or been in contact
wash animal blankets with soap or any other commercial detergent
those living on farms should also be aware of the risk that semi-domestic
cats (feral domesticated and farm cats) could shed the virus
into poultry feed or housing, leading to exposure of poultry.
The risk to humans from an H5N1-infected cat
is hard to quantifyref.
Cats naturally hunt wild birds, will choose sick birds and have close contact
with humans as companion animals. Given that one cat can infect another,
the risk to humans cannot be zero. However, as H5N1
remains poorly adapted to humans, the cat's infection will not cross over
easilyref.
The present evidence is that cats with infectious H5N1
are quite ill, so the risk of acquiring H5N1 from
a clinically normal cat may be negligible. Also, risk will be minimal in
areas where there is no H5N1. While it could be argued
that owners should be cautious around cats with respiratory infections,
cats (like humans) catch many of these. For example, there are common infections
confusingly called 'cat flu'' which are not caused by an influenza virus
at all but are due to either a cat calicivirus or herpesvirus. Humans are
actually at considerably greater risk from other zoonoses in cats such
as toxocara, toxoplasmosis and ringworm, and basic hygiene measures for
handling companion animals are important to protect against theseref)

available WHO World Survey of Rabies (1999) there have been, worldwide,
7578 and 1157 laboratory confirmed cases in dogs and cats, respectively.
In the Russian Federation, the figures for 1999 were 465 and 253ref.
Cats should be vaccinated, regardless of their indoor/outdoor status. Many
states have enacted rules or legislation that requires that cats be vaccinated
with a 3-year vaccine once every 3 years. The rationale for this requirement
was that some cats suffer vaccine-related sarcomas which may prove fatal
to the cat. Although vaccine-related sarcomas are not pleasant, it is better
than exposing one's family to rabies. Vaccinating cats with a 3-year vaccine
once every 3 years has reduced the rate of vaccine-related sarcomas. Rabies
is a deadly disease, but it can present in several forms, one of which
is a change in behavior. Animals may become either aggressive or withdrawn.
Some may appear lethargic and ill, but are not recognized as having a behavior
change. Also, other diseases present in the animal, such as liver disease,
may confuse the diagnosis)

a panther run-in with domestic cats or feral cats
feline
immunodeficiency virus (FIV) is a worldwide-occurring lentivirus discovered
in 1987 that severely impairs the immune function of infected domestic
cats, in which the prevalence has been reported to range from 1 to 28%.
FIV has not been found, so far, to infect humans, and, due to structural
and biological similarities, it represents a promising model for HIV.
A dual-subtype FIV commercial vaccine -- the 1st animal lentivirus vaccine
-- was approved by the USDA in 2002. We are not aware of its efficacy in
non-domestic feline species. The primary mode of FIV transmission is sexual
contact and bite wounds. On rare occasions, infection is transmitted from
mother to cub, usually upon passage through the birth canal, or, when newly-born
cubs ingest contaminated milk. Common among the symptoms are persistent
fever; diarrhea, with a loss of appetite; poor coat condition; chronic,
or recurrent, infection of the skin and urinary bladder; abortions; behavior
changes; and seizures. All of this is followed by slow, but progressive,
weight loss and neurological disorders. Lion prides are more affected by
the disease (e.g. in Kruger National Park, in South Africa), because they
are highly sociable and are in constant physical contact with each other.
Other felines, the leopard and cheetah, also have FIV, but, are said to
be less susceptible, because they are more solitary.
feline respiratory disease complex / feline influenza : a group
of contagious viral infections of the upper respiratory tract in cats,
characterized by fever, sneezing and coughing, and discharges from the
nose and eyes. The usual cause is infection with
a calicivirus
felid or feline herpesvirus 1 / feline rhinotracheitis virus => feline
viral rhinotracheitis : the feline respiratory disease complex, usually
manifesting as an acute febrile infection of the upper respiratory tract
and conjunctivae in kittens, with a mucopurulent discharge from the eyes
and nose, photophobia, coughing, and sneezing.
feline urological syndrome (FUS) : dysfunction of the feline lower
urinary tract. In male cats there is usually partial or complete obstruction
from uroliths or other plugs, and in females there is more often cystitis
or urethritis. There may be various causes, including decreased physical
activity and excessive dietary magnesium.
pulmonary infiltration with eosinophilia (PIE) syndrome / eosinophilic
pneumonia : a syndrome of diffuse pulmonary infiltration and peripheral
eosinophilia, seen in dogs and sometimes cats; the cause varies but sometimes
it may be an allergic reaction. Affected animals are dyspneic with decreased
exercise tolerance
feline spongiform encephalopathy
(FSE) is a TSE.
When the identification of FSE was initially published by the Bristol Veterinary
School in 1990, this was the 1st indication that BSE is capable of crossing
the species barrier and sparked fears that it might affect humans as well.
This was confirmed 6 years later. According to DEFRA's
BSE-site's update of 30 Jun 2003, 90 FSE cases have been diagnosed
in the UK so far, including 20 since 1996 (the last one in 2001). Of these
20 cases, 8 could be clearly identified as having been born after September
1990 (i.e., the date the ban on the use of SBO was extended to any animal
feed). 5 additional cases have been reported outside the UK, namely Norway,
Liechtenstein (1 case each), and Switzerland (2 cases). In addition, 21
cases of TSE regarded to be FSE have been reported in exotic felids in
zoos, their age ranging between 6 and 17 years. Of those, 16 have been
recorded in the UK (5 Acinonyx
jubatus,
2 Panthera leo,
3 Leopardus
pardalis,
3 Puma concolor,
& 3 Panthera
tigris).
5 additional cases, in Acinonyx
jubatus,
have reportedly been identified outside the UK: 1 in Australia (1991; the
very 1st case diagnosed in a cheetah), 1 in Ireland, & 3 in France.
4 of these cases are known to have originated in the UK, while one was
diagnosed in a cheetah born in France. A presumptive FSE case in an imported
Catopuma
temmincki
in an Australian zoo was reported in August 2002.
Mustelidae
Lutrinae
Enhydra
Enhydra
lutris (sea otter) : Sarcocystis
neuronais a parasite that originates in the feces of opossum --
a small marsupial not native to California -- and is known to cause encephalitis.
Researchers are unclear how the otters came into contact with the feces.
The North America or Virginia opossum (Didelphis virginiana) is
native in the East, but was introduced to the West of the Great Plains
and the Rocky Mountains
Recently, a number of veterinarians and pathologists have observed
a spike in mortality in young ferrets < 1 year of age. Deaths occur
in animals that appear to have overwhelming bacterial infections that are
unresponsive to a wide range of treatments. Several unusual findings have
linked animals necropsied on both the east and west coasts of the USA,
and suggest that a new syndrome may have appeared in our pet ferret population.
This is not an epidemic situation, nor does the disease appear very contagious
at this time. The condition is sporadic and most commonly affects only
a single animal in a household. Unfortunately, even with the highest levels
of care, few animals have survived this condition once diagnosed. Investigations
on these cases to date have failed to disclose a cause for the condition.
This is likely attributable to the slow progression of disease and the
number of antibiotics, anti-inflammatory drugs, and other treatments that
are often used in a valiant attempt to keep the animals alive. Recent postings
on the Ferret Mailing List (FML) and in other circles on this new syndrome
have sparked a lot of interest in this "mystery disease". One approach
that has not yet been tried is to obtain diagnostic samples from veterinarians
and shelter operators prior to any attempted therapy. This may be in the
form of surgical biopsy of abscessed skeletal muscle or lymph nodes, or
necropsy tissue from animals that have been euthanized without treatment.
The prospect of euthanizing an animal without attempting treatment is loathe
to all of us; however, the extended use of antibiotics and other drugs
in these cases (even those to which the organism is not particularly sensitive
to) likely lowers the concentration of the agent to an extent where we
cannot successfully culture it, or view it under the microscope. There
is no indication that antibiotics themselves are causing the problem --
however it is very likely that they are masking the true culprit. Let me
also clarify that this particular disease has not been linked to any breeder,
pet store, distribution center, activity, or anything at all at this point.
Symptoms & signs : persistent high
fever (> 104°F or 40°C), markedly elevated WBC count, discomfort
or pain in the hind legs
enlargement of one or more peripheral nodes, cellulitis or abscessation
of peripheral nodes or adjacent soft tissue. Proper collection of tissues
is paramount. Surgical biopsies, such as enlarged lymph nodes, should be
bisected and several touch imprints of the cut surface prepared and air-dried
for cytologic examination and gram staining. Half of the tissue can then
be placed in formalin; the other half should be immediately frozen for
bacteriological examination. If an untreated animal is presented for necropsy,
the widest range of tissues should be taken. Once again, equal halves can
be formalin-fixed and frozen. Screening of cytologic preps and formalin-fixed
tissues will be performed to determine whether further investigation (bacteriology,
virology, etc.) is warranted on frozen tissue.
Aleutian
mink disease parvovirus => Aleutian disease of minks (ADM) :
a chronic, progressive disease of mink, caused by a parvovirus, marked
by inappetence, weight loss, lethargy, polydipsia, and hemorrhages; death
may result from kidney failure.
transmissible mink encephalopathy
(TME) is a TSE.
An outbreak occurred in Wisconsin in the 1980s
canine distemper
virus (CDV)
is a morbillivirus which, in 1987-1988, caused high mortality among Baikal
seals (Phoca siberica) in Lake Baikal in Siberia, and was suspected
of having caused a die-off of crabeater seals in Antarctica, in 1955. In
recent years, other morbilliviruses (phocine and cetacean morbilliviruses)
have caused several major epizootics among aquatic mammal populations in
various regions of the world
