Pathogenesis of Diarrhea Caused by Parasites & Diet

These flashcards cover key terms and concepts related to the pathogenesis of diarrhea caused by parasites and dietary indiscretion in animals.

Parasitic Diarrhea

Occurs when parasites infect the G.I. tract, damaging the mucosa and disrupting normal absorption of fluids and electrolytes.

Coccidia

A type of protozoan parasite that can cause diarrhea, with common species including Cystoisospora spp. and Eimeria spp.

Giardia duodenalis

A protozoal parasite that causes maldigestion and malabsorption, leading to diarrhea, weight loss, and growth retardation.

Hookworms

A group of nematodes such as Ancylostoma spp. and Bunostomum spp., known for causing anemia and dark, tarry diarrhea.

Dietary Indiscretion

Ingestion of inappropriate or spoiled food, leading to gastrointestinal irritation and inflammation, resulting in diarrhea.

Lactose Intolerance

A condition where cats lose the ability to digest lactose, leading to fermentation and diarrhea.

PCR Testing

A diagnostic approach with higher sensitivity and specificity for detecting specific parasites in fecal samples.

Strongyloides

A genus of parasites that can cause diarrhea and are transmitted through ingestion or skin penetration of infective larvae.

Eimeria spp.

A species of coccidia that primarily infects cattle, sheep, and goats, causing diarrhea and other clinical signs.

Trichuris vulpis

A nematode that can infect dogs and cats, leading to weight loss and blood in diarrhea.
