Prevalence and molecular identification of protozoan intestinal parasitic infections in cancer patients and a control group

Chemotherapy, aside from corticosteroids, increases susceptibility to intestinal Protozoan infections in patients with hematological malignancies, particularly those with lymphoma and leukemia. The results indicated a higher risk of intestinal Protozoan infections, including opportunistic infections, in the cancer patients than in the control group. Cystoisospora belli and Cryptosporidium parvum were found to cause diarrhea in hematological malignancy patients undergoing chemotherapy.
