1

Name the main 3 causes of cat flu

Herpes virus calici virus and chlamydia felis

2

Why is it difficult to identify carriers of FHV?

Latency - hides in the trigeminal nerve ganglia and cannot be identified
Intermittent shedding which stops and starts upon deactivation - can only identify them at the point of shedding

3

Name 2 common signs associated with FHV?

Salivation and dendritic eye ulcers

4

Name 3 common clinical symptoms of FCV

Vesicles on the tongue
Transient limping syndrome
Gingivitis

5

What is the best way to diagnose cat flu agents?

PCR from oropharyngeal or ocular swabs

6

What antibiotic is the first line of treatment against cat flu?

Doxycycline

7

How does vaccination help with cat flu?

Prevent clinical disease by immune r spouse and reduces shedding

8

What is the most common cause of conjunctivitis in cats?

Chlamydia felis

9

Core vaccines for cats

FCV, FHV, feline distemper and rabies

10

What is infection of cats with birdetella brinchiseptica associated with?

Living with a dog in the household - prt of kennel cough

11

How are cats infected with toxoplasma Gondi?

Ingestion of cysts in the tissues of IH
In Usero or transplacentally or through milk to kittens

12

How are people most likely to become infected with toxoplasma?

Gardening, eating unwashed vegetables or eating raw meat

13

What is the treatment for toxoplasma

Climdamycin

14

What is a differential for toxoplasma infection in dogs

Neospora

15

What type of haemoplasma cause disease. In cats

Mycoplasma haemofelis

16

How do haemoplasmas cause disease in cats?

Haemolysis as they attach to RBCs

17

What antibiotic is good for treating mycoplasma?

Doxycycline

18

What is a pro virus?

DNA copy of the virus imtegratd into host DNA resulting in a persistently infected cell

19

What are you looking for when diagnosing feline leukaemia virus?

P27 core protein and antigen in the blood

20

What are you looking for when diagnosing feline immunodeficiency virus?

P24 protein and group 40 envelope glycoproteins and the antibody to the virus

21

How is feLV spread amongst cats?

Close prolonged contact - oronasal exposure to infected cats saliva

22

How is FIV spread between cats

Biting and fighting via infected saliva and blood

23

How well are both FIV and feLV spread vertically?

FeLV is effectively spread by veritable tramsmission but FIV will on,y have 1/3 of kittens affected from an infected queen

24

Explain the types of infection cats can get with FeLV
Abortive infection
Regressive infection
Progressive infection

Abortive infection - they overcome the virus without any provirus made
Regressive infection - cats amount immune response and overcome but positive for the pro virus
Or can have p27 in the blood and overcome the virus - transient viraemia
Or can have bone marrow infection where you see p27 associated with cells released from the bone marrow
Progressive infection - lifelong persistent viraemia

25

How would you detect feLV infection of the bone marrow?

Immunoflourescence to check for p27 in particular cells

26

What is FIP

Fine infectious peritonitis a fatal systemic infection cation caused by a mutation of feline coronavirus

27

What type of disease can feline coronavirus cause?

No disease. Enteritis or FIP

28

What part of th body does coronavirus infect?

GI tract

29

How is coronavirus transmitted between cats

She's in faeces and spread by faecal oral transmission by cats sharing litter trays
