Cryptosporidiosis and giardiasis in dogs and cats: veterinary and public health importance.
Dogs and cats are the only domestic animals that still routinely reside in the same domicile as their owners around the world, and hence the interest in their role as reservoirs of potentially zoonotic agents. In the case of cryptosporidiosis and giardiasis, current data suggests that dogs and cats do not routinely share their infections with healthy people. Dogs are hosts of Cryptosporidiumcanis and Giardiaduodenalis Assemblages C and D. Cats are hosts to Cryptosporidiumfelis and G. duodenalis Assemblage F. Dogs and cats (and other animals) are sometimes infected with sub-Assemblage AI, an Assemblage also found in people, but people usually have sub-Assemblage AII. Unfortunately, severely immunocompromised individuals and malnourished children can be made ill by infections with C. canis and C. felis. People should practice good sanitation and hygiene to minimize environmental contamination and contact with the infectious (oo)cysts that may be shed by their pets.
