Which parasites can typically be detected in a fecal examination?

Fecal examinations are primarily used to identify parasitic infections in the gastrointestinal tract, making them especially effective for detecting types of worms that cause intestinal issues. Roundworms, hookworms, and whipworms are all types of helminths (worms) that inhabit the intestines of their hosts.

During a fecal examination, the presence of these parasites can be identified through various methods, such as flotation or sedimentation techniques. These methods allow veterinary technicians to visualize and confirm the presence of eggs or larvae shed by these parasites in feces.

In contrast, the other choices consist of parasites that are not typically identified through fecal analysis. Fleas and ticks are ectoparasites and are usually detected by visual inspection of the animal's coat and skin, rather than through fecal examination. Heartworms, while a serious concern, are often diagnosed through blood tests rather than fecal exams since they reside in the heart and pulmonary arteries, not in the intestines. Mange mites and lice, similar to fleas and ticks, are external parasites, meaning they affect the skin and fur, again necessitating direct examination instead of fecal analysis.
