1) Infections with the raccoon roundworm, Baylisascaris
procyonis, have been increasingly identified in domestic dogs.
These infections are of particular concern because: A.
Baylisascaris procyonis is an unusually large ascarid, so
infections often result in intestinal impactions, particularly
in small-breed dogs. B. When people, particularly children,
ingest larvated B. procyonis eggs, the larvae may migrate
extensively and induce severe neurologic disease. C. Adults of
B. procyonis commonly migrate aberrantly in the lungs of the
atypical canine host, resulting in severe respiratory disease.
2) A 12-week-old puppy is presented with a three-week history of
intermittent mucoid diarrhea. The puppy has been treated with
sulfadimethoxine for the last two weeks, but the diarrhea
persists. Fecal flotation by centrifugation reveals these
parasites (Figure 1). What is the most effective treatment
protocol? A. 50 mg/kg fenbendazole orally every 24 hours for
five days B. 25 mg/kg albendazole orally every 12 hours for t
