الملخص EN

Cryptosporidium parasite is causing opportunistic cryptosporidiosis diseases among immunocompromised patients that lead to acute and persistent diarrhea and health complications, especially in developing countries.

this study amid to determine the occurrence of c.

parvum among immunocompromised patients presenting at al-Thawra hospital in Ibb city- Yemen.

sample of the study (87) stool specimens were collected between November 2016 and July 2017.

the required data were obtained by a designed questionnaire.

the result revealed that the overall rate of c.

parvum was 62 (71.26%) observed among immunocompromised patients and both males and females had nearly equal frequency rates of infection.

the highest rate of infection was 80% reported within age less than 10 years and 78.3% among patients who coming from the rural area.

also, it was found 83.33% of infected patients drinking from piped water with significant difference (p<0.05).
