Coccidiosis among immuno-competent and -compromised adults.

There was significant increase in coccidia positive cases among Hodgkin lymphoma receiving chemotherapy as compared to control group (p < 0.05). The increase was highly significant in the group of acute lymphocytic leukaemia receiving chemotherapy as compared to control group (P < 0.01). The total percent of cases with single type of coccidia were 12.2% compared to multiple coccidial infections (4.3%). The most commonly associated parasite was Cryptosporidium. The total cryptosporidial infections (single and mixed with other coccidia) were 12.1% of the total studied cases. In the immunocompromised the prevalence was 14.3%. In the immunocompetents with diarrhoea, was 8.3% and in control was 5.6%. Microsporidial infections (single and mixed with other coccidia), being the least detected among the four intestinal spores forming coccidia, were 2.4% in the immunocompromised groups. No Microsporidium was detected in the immunocompetent or adult control groups. The total cyclosporal infections (single and mixed with other coccidia) were 6.3% of the total studied cases. In the immunocompromised groups, the prevalence was (8.3%) where in immunocompetent group, was 2.8%. None was detected in the control subjects. Single cyclospora was 3.0% while mixed Cyclospora represented 3.3% of all studied cases. The Isospora infections (single and mixed) were 3.8% of total patients. The prevalence among immunocompromised group was 5.2% and in immunocompetent patients was 2.8%.
