Cryptosporidium, isospora and strongyloides in AIDS.

ABSTRACT

BACKGROUND: Diarrhoea is a common presentation in patients with AIDS. It occurs due to a number of parasites which are seldom seen in immunocompetent hosts. METHODS: Between January 1993 and July 1994, faecal specimens from 77 patients with AIDS presenting with diarrhoea of more than a month's duration were examined by direct wet mount microscopy of saline and iodine preparations and by the modified Ziehl-Neelsen stain. RESULTS: Cryptosporidium, Isospora and Strongyloides stercoralis alone or in combination were present in 29 of the 77 patients. CONCLUSION: The presence of these parasites highlights their pathogenic potential for immunocompromised patients with AIDS. Diarrhoea due to Isosporais responsive to treatment, hence their identification has therapeutic implications as well.
