Medical Details

Transmission

Infection occurs by ingesting soil or feces containing infective oocysts. The parasite thrives in damp, crowded, or unsanitary conditions.

Progression & Stages

Following ingestion, the parasite replicates in intestinal cells. Clinical signs include watery or mucus-filled diarrhea, which may contain blood. Dehydration is the primary risk in small animals.

Diagnosis

Diagnosis is made by examining a stool sample under a microscope (fecal flotation) to identify the eggs (oocysts).

Treatment Protocols

Sulfa-type antibiotics (like Sulfadimethoxine) are the standard treatment. They stop the parasite from reproducing while the animal's immune system clears the infection. Hygiene is critical to prevent reinfection.

Prevention

Sanitation is key. Regularly cleaning runs and yards and preventing consumption of rodent/bird feces reduces risk.

Prognosis

Prognosis is excellent with treatment. Severe cases in very young or immunocompromised animals can still lead to fatal dehydration if ignored.
