positive serum antibody titer PLUS clinical signs
What is the numb er one treatment of RMSF?
What is the most common cause of canine ehrlichiosis?
What organisim is NOT passed transovarially in the tick?
When is the acute phase of ehrlichiosis seen?
in the spring and summer
When is the chronic phase of ehrlichiosis seen?
trick question. lasts months to years, reason for no distinct seasonal phase (unlike RMSF)
What are the 2 most common things seen on a CBC in regards to canine ehrlichiosis diagnosis?
nonregenerative anemia, and thrombocytopenia
What are the 2 most common things seen on a chemistry in regards to canine ehrlichosis diagnosis?
hypoalbuminemia and hyperglobulinemia
What are the 2 biggest ways to diagnose canine ehrlichosis?
serology and PCR
In regards to canine ehrlichosis, can serology remain positive with treatment?
Where does the organism mycoplasma haemofelis live in cells?
macrophages (cats can't clear infection and remain carriers)
What clinical feature is rare with mycoplasma haemofelis?
What does the risk of borrelia burgdorferi infection correlate with?
prevalence of infected ticks and likelihood of being bitten
What % of seropositive dogs are asymptomatic for lyme disease?
How much time does transmission of borrelia burgdoferi require the tick to be attached?
> 48 hours
What is the most common clinical sign of Lyme disease?
shifting leg lameness due to polyarthritis
Lyme disease can the be causative agent of what two diseases?
acute renal failure and glomerular disease
Routine ELISA and IFA testing does or does not differentiate between dogs with active Lyme disease and earlier exposure or vaccination?
what does a positive borrelia antibody test indicate?
exposure, does not prove that clinical signs were caused by borreliosis
is routine vaccination recommended for Lyme disease?
How is leptospirosis spread?
by recovered animals that shed leptospira in their urine for months to years after infection
What is the most common route of exposure to leptospirosis?
What are the primary targets of leptospirosis?
liver and kidneys
What is the most common cause of acute renal failure/ nephritis?
For leptospirosis, what MA titters are suggestive, and what ones are highly indicative?
1:400 is suggestive and 1:800 is highly indicative
What may be needed to support some dogs with oliguric AIRF from leptospirosis to achieve a successful outcome?

What is a reproductive disorder transmitted in infected semen, vaginal discharges, aborted fetal tissues and urine?
What enables the feline corona virus to infect macrophages and cause Fip?
mutation during intestinal replication
Infection with feline corona virus does not equal what?
feline infectious peritonitis
What are characteristic lesions of FIP
immune mediated vasculitis, pyogranulomtous inflammation, exudative fibrinous polyserositis
Where do most FIP cats come from?
catteries and shelters
What is the biggest cause of mutation of the FCoV?
How is FIP transmissed?
fecal excretion, oral eposure, crowded confinement
When is the greatest risk for developing FIP from FCoV?
6 to 18 months after initial infection with FCoV
What are signs of Wet form of FIP?
abdominal effusion, pleural effusion, dual cavity effusion
