A

mild-moderate elevation in temperature, hemorrhagic diarrhea, anorexia, leukopenia, dehydration, depression, spontaneous abortions, sudden kitten death, enlarged abdomen
can also cause cerebellar hypoplasia in kittens that contract panleukopenia in utero (cerebellum is attacked in utero and kitten has severe ataxia when born)

34
Q

how is panleukopenia transmitted?

A

fecal-oral

35

supportive care, anti-emetics, antibiotics, plasma/blood transfusion, isolation, IVF, nutritional support

37
Q

what family does FIP belong to?

A

coronavirus

38
Q

what is the victim signalment for FIP?

A

1-3 year old cats, multi-cat households, cats positive for FeLV or FIV

39
Q

what body systems does FIP affect?

A

abdominal organs, abdominal lymph nodes, respiratory system, nervous system

40
Q

how is FIP transmitted?

A

fecal-oral, in utero

41
Q

what clinical signs are seen in FIP cats?

A

wet form: peritonitis, vicious yellow exudate from abdomen, pleuritis
dry form: lesions on organs (kidneys, liver, brain, blood vessels), nonspecific signs (some show little to no signs at all), wasting syndrome, neurologic signs (ataxia, seizures)

42
Q

how is FIP diagnosed?

A

based on CS, abdominal centesis (for wet form), necropsy

43
Q

how is FIP treated?

A

palliative care and euthanasia

44
Q

what is the fatality rate for feline leukemia virus?

A

85% of persistently infected cats die within 3 years of diagnosis

45
Q

what is the main body system FeLV affects?

A

immune system
malignant WBC disease

46
Q

what family does FeLV belong to?

A

retro virus

47
Q

what are the clinical signs of FeLV?

A

pale gums, enlarged lymph nodes, weakness/lethargy, URI signs, fever, diarrhea, poor hair coat, stomatitis
some cats are asymptomatic until disease progresses. and becomes severe

48
Q

what are common FeLV-associated disorders?

A

lymphoma, anemia

49
Q

how is FeLV transmitted?

A

friendly disease
through prolonged close contact with infected cat (grooming, fighting, intimate contact)
kittens can contract in utero

50
Q

how is FeLV diagnosed?

A

ELISA test (antigen)
if kitten is positive retest 3 months later to see if kitten has overcome on its own
can test as early as 30 days post exposure

51
