Parasitic Zoonoses Slides

Dear User, Parasitic zoonoses are diseases primarily of animals which are caused by parasites that can be transmitted to humans.

In animals, intestinal parasites can cause gastrointestinal upset, vomiting, diarrhea, blood loss, intestinal obstruction, weight loss, pot-bellied appearance, and general failure to thrive.

In people, zoonotic parasites cause a variety of conditions depending on the parasite, the route of infection, the person’s age and immune status, and the size of the infectious dose. The signs in humans range from sub-clinical (no noticeable problems) to blindness and death.

The most likely candidates for parasitic zoonosis are young children. It is because they are less careful about hygiene, are likely to put their hands in their mouths, commonly play in sand or dirt, are in very close contact with the pet, and may eat grass or soil contaminated with parasite eggs.

Immunocompromised adults are at increased risk for zoonotic disease while others are at increased risk because of high exposure due to occupation, e.g., veterinary workers, farm workers, animal breeders.
