Q

What age cats are most likely infected by FCV acute oral and upper respiratory tract?

A

YOUNG

20
Q

How do you treat FCV acute oral and upper respiratory tract?

A

Usually self limiting and resolve within a few days, only symptomatic treatment is needed

21
Q

What is FCV Feline chronic gingivostomatitis?

A

Caudal stomatitis must be identified in order to diagnose FCGS

22
Q

What is FCV limping syndrome? And when can it occur?

A

Lameness associated with acute viremia and localization of virus and/or immune complexes in joints. Lasts 24-48 hours and can shift between legs

Can occur following vaccination or infection

23
Q

What is paw and mouth disease?

A

Erosion of paw pads and inflammation if the interdigital areas. Probably a milder form of VS-FCV. Only described in Austrailia

24
Q

What is VS-FCV?

A

Facial edema (vasculitis), hair loss, systemic crusted lesions, paw lesions

25
Q

What are the implications of VS-FCV?

A

High mortality (70%), strand that causes this is not the same common resp FCV, vaccine may not be protective

26
Q

Is there a vaccine for FCV?

A

Yes, part of FVRCP vx

27
Q

What type of infection is panleukopenia?

A

Systemic

28
Q

What type of virus is panleukopenia?

A

ssDNA, non enveloped, Parvo virus.

Therefore also called feline Parvo virus (FPV)

29
Q

Where does panleukopenia replicate?

A

lymphoid tissues (thymus, spleen, bone marrow) and other rapid dividing cells: intestine, bone marrow, and in embryonic tissue.

30
Q

Is panleukopenia stable?

A

Yes very stable in the environment! B/c non enveloped , can stay in environment for unto 6 months

31
Q

If pregnant cats get infected with panleukopenia what happens?

A

FPV antigen is present in the cerebellum of kittens for weeks, causing cerebella hypoplasia

32
Q

What is different about panleukopenia and FHV and FCV?

A

Persistent infections and persistent viral shedding are rare

33
Q

Explain the possible pathological outcomes of panlleukopenia

A
34
Q

What are the clinical signs of panleukopenia?

A

-hemorrhagic enteritis
-Segmental hyperaemia
-Intestinal damage/ sloughing of gut epithelium with fibrinous casts
-(Same GI signs as dogs)
-Dehydrated
-Cerebella hypoplasia (leading to neurological signs)

35
Q

Is there a vx for panleukopenia?

A

Yes part of FVRCP, works very well

36
Q

What is H5N1?

A

High pathogenic avian influenza

37
Q

How doe cats get infected with H5N1?

A

By eating an infected bird

38
Q

What H of influenza can infect cats?

A

H5

39
Q

How can cats get infected with cow pox?

A

Through eating rodents, therefore outdoor cats. no aerosol transmission has to touch lesion

40
Q

Where is feline cowpox found?

A

Mainly in Europe, not in North America

41
Q

What feline virus is zoonotic? What does it lead to?

A

Feline cowpox, can lead to necrotising ulcers and lymphadenitis

42
Q

How do you treat feline cowpox?

A

Typically self limiting, but can go systemic, causing pulmonary cowpox

43
Q

Sars-CoV-2/ COVID 19 is what kind of virus?

A

enveloped ss+ RNA virus, corona virus

44
Q

What clinical signs do cats infected with Sars-CoV-2 have?

A

None but they produce a lot of virus

45
Q

Who can cats transmit Sars-CoV-2 to?

A
  • cat-to-cat
  • Human to cat transmission
  • Cat to human transmission not demonstrated (although likly possible)
