Infectious Diseases Flashcards
Name the main 3 causes of cat flu
Herpes virus calici virus and chlamydia felis
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
Name 2 common signs associated with FHV?
Salivation and dendritic eye ulcers
Name 3 common clinical symptoms of FCV
Vesicles on the tongue
Transient limping syndrome
Gingivitis
What is the best way to diagnose cat flu agents?
PCR from oropharyngeal or ocular swabs
What antibiotic is the first line of treatment against cat flu?
Doxycycline
How does vaccination help with cat flu?
Prevent clinical disease by immune r spouse and reduces shedding
What is the most common cause of conjunctivitis in cats?
Chlamydia felis
Core vaccines for cats
FCV, FHV, feline distemper and rabies
What is infection of cats with birdetella brinchiseptica associated with?
Living with a dog in the household - prt of kennel cough
How are cats infected with toxoplasma Gondi?
Ingestion of cysts in the tissues of IH
In Usero or transplacentally or through milk to kittens
How are people most likely to become infected with toxoplasma?
Gardening, eating unwashed vegetables or eating raw meat
What is the treatment for toxoplasma
Climdamycin
What is a differential for toxoplasma infection in dogs
Neospora
What type of haemoplasma cause disease. In cats
Mycoplasma haemofelis
How do haemoplasmas cause disease in cats?
Haemolysis as they attach to RBCs
What antibiotic is good for treating mycoplasma?
Doxycycline
What is a pro virus?
DNA copy of the virus imtegratd into host DNA resulting in a persistently infected cell
What are you looking for when diagnosing feline leukaemia virus?
P27 core protein and antigen in the blood
What are you looking for when diagnosing feline immunodeficiency virus?
P24 protein and group 40 envelope glycoproteins and the antibody to the virus
How is feLV spread amongst cats?
Close prolonged contact - oronasal exposure to infected cats saliva
How is FIV spread between cats
Biting and fighting via infected saliva and blood
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
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
