Question 1

FIV tests in kittens < 6 mos are unreliable because

Answer 1

1. Ab response to FIV infection takes weeks-months to become detectable (so a negative test result could occur in an exposed, infected kitten who has not seroconverted)
2. Uninfected kittens from FIV-infectdd queens can test Ab+ as a result of MDAs (colostrum); MDA-derived Abs can persist until 6 mos

Question 2

FeLV Ab titer is __

Answer 2

Not a reliable diagnostic test

Question 3

Because the FeLV Ag test as the SNAP test is considered ___, it is no longer the case that ___

Answer 3

Reliable and highly specific; the IFA test is considered necessary to confirm FeLV infection (rather, it merely corroborates positive SNAP results)

Question 4

A positive SNAP test result for FIV is not considered __ and infection is ___

Answer 4

Confirmatory; confirmed with a western blot

Question 5

Any cat having a positive FeLV SNAP test result is considered __

Answer 5

To be shedding virus regardless of health status

Question 6

Generally, negative FIV Ab test result may __

Answer 6

Still be reliably interpreted as negative for exposure and active infection

Question 7

Fungal agents most likely to infect humans upon direct exposure

Answer 7

The dermatophytes and Sporothrix spp

Question 8

MRSA in cats is generally acquired from

Answer 8

Humans and is thus considered a “reverse zoonosis” or “humanosis”

Question 9

Answer 9

30+ days; it is detectable at 1 week post exposure with qRT-PCR and at 2 weeks with pro viral DNA detection

Question 10

Outcomes of FeLV infection are classified as

Answer 10

Abortive infection, regressive infection, and progressive infection

Question 11

FIV Abs are detectable at ~ __ after exposure

Answer 11
