2. Canine circovirus (DogCV) is a novel dog virus discovered in 2012.

True

False

3. Which of the following is not true about canine circovirus?

It is a non-enveloped DNA virus.

It is very resistant to most disinfectants, surviving well in the environment and outside of the host.

It can be transferred to humans via the fecal-oral route.

It is unique to the dog but is closely related to porcine circovirus 2 by molecular analyses.

It can be detected in the liver, spleen and lymph nodes by PCR.

4. Postmortem exam of a dog infected with canine circovirus would reveal:

Vasculitis, vascular necrosis and hemorrhage in the GI tract, liver, spleen kidneys and lungs.

Granulomatous lymphadenitis of mesenteric LN.

Virus detected in the liver, spleen and lymph nodes by PCR.

None of the above.

All of the above.

5. The role of DogCV in pathogenesis of disease remains to be determined.

True

False

6. DogCV should be considered in cases of unexplained:

Pallor, hemorrhagic stroke or leukemic reticuloendotheliosis.

Condyloma, hemorrhagic fever or venous congestion.

Vasculitis, hemorrhagic gastroenteritis or granulomatous lymphadenitis.

Pulmonary edema, hemorrhagic pancreatitis or nodular nonsuppurative panniculits.

Gingivostomatitis, hemorrhagic macules and papules or aerobic cellulitis.

7. Examination of tissues from 21 archived necropsy cases with hemorrhagic gastroenteritis, vasculitis, or granulomatous lymphadenitis indicated:

There was no correlation to the initial discovery of DogCV.

DogCV was detected in 10 of 21 cases.

DogCV was detected in 100% of the cases.

DogCV is not able to be detected using current testing methods.

None of the above.

8. The Ohio Department of Agriculture concluded that the primary contributing factor, which made 19 dogs in Cincinnati and Akron with hemorrhagic gastroenteritis, weight loss and lethargy sick, was:

Another new and unnamed virus.

E. coli.

Canine circovirus.

Not canine circovirus.

Toxoplasma gondii.

9. The Diagnostic Center for Population and Animal Health at Michigan State University concluded that the cause of illness in 20-30 dogs in Ann Arbor with hemorrhagic gastroenteritis, abdominal pain and interstitial pneumonia was:

Another new and unnamed virus.

E. coli.

Canine circovirus.

Not necessarily canine circovirus.

Toxoplasma gondii.

10. The goal of Dr. Pesavento's Shelter Dog Project is to answer the question:

Why is the strain of DogCV present in shelter dogs more resistant to disinfectants?

Are shelter dogs carriers of DogCV?

Are shelter dogs at greater risk for infection with DogCV compared to pets in homes?

What factors in the shelter environment make shelter dogs more at risk to become infected with DogCV?

Is illness caused by DogCV more severe in shelter dogs than pets in homes?

11. Detection of DogCV in fecal samples using PCR indicated:

14/204 (7%) of normal dogs were positive for DogCV.

19/168 (11%) of dogs with diarrhea were positive for DogCV.

68% of the dogs with diarrhea that were positive for DogCV were co-infected with at least one other GI pathogen.

All of the above.

It is not possible to test for DogCV in fecal samples.
