Quick Summary:

• Cystoisosporiasis is a disease caused by infection of the small intestine by a protozoan parasite that is transmitted fecal-orally through contaminated food and water. It is found worldwide, most commonly in resource-limited tropical and subtropical countries with poor sanitation conditions
• Cystoisosporiasis is caused by a tiny parasite called Cystoisospora belli (formerly Isospora belli), which can be seen under a microscope. The infection was formerly known as Isosporiasis. Infection is acquired by ingesting food or water contaminated with the infective form of the parasite i.e., the sporulated oocysts, which are formed by the maturation of oocysts passed in the feces of infected individuals
• The freshly passed oocysts are not infective and take 1-10 days to mature (sporulate) depending on the environmental conditions. Therefore, direct person-to-person transmission and transmission via freshly contaminated food or water do not occur
• Cystoisosporiasis is characterized by watery diarrhea. Abdominal pain, loss of appetite, nausea, weakness, fever, and weight loss are some other symptoms associated with the condition. The illness is usually mild and self-limited in individuals with healthy immune systems
• However, those with weak immunity, such as HIV positive individuals, are at an elevated risk of developing severe prolonged diarrhea and extra-intestinal manifestations (e.g., chronic acalculous cholecystitis)
• Stool samples over several days are analysed to detect the presence of the parasite to arrive at a definite diagnosis. The various diagnostic tests for Cystoisosporiasis include microscopic identification of parasite and polymerase chain reaction, to detect the protozoan genetic material
• Cystoisosporiasis is typically treated using antibiotics. Rest and plenty of fluids are prescribed to maintain hydration. Severe cases may require hospitalization too. In most individuals with healthy immunity, the prognosis of the condition is excellent
• The main method of preventing Cystoisosporiasis is to avoid consuming contaminated food and water. Thorough hand washing, thoroughly washing raw vegetables and fruits, using clean water for drinking, and cooking food to proper temperatures can help reduce the chances of contracting the infection
