Cryptosporidium Characteristics
- Causes profound diarrhea in AIDS patients, particularly in immunocompromised individuals, such as those with HIV
- Unicellular, partially acid-fast, and releases oocytes through feces, which can be absorbed orally
Infection and Transmission
- Infectious cysts are excreted in watery stool, containing four motile sporozoites that attach to the small intestinal wall, causing damage
- Oocysts can be transmitted through contaminated water, appearing like amethyst under staining
Diagnosis and Treatment
- Nitazoxanide is a treatment option for immunocompetent individuals
- Spiromycin is another treatment option, although not FDA-approved in the US
- Filtration can be used to remove oocysts from water
