Oppotunistic parasitic infections represent one of the major chalenges in the managment of immunodeficient patients. These patients who include a wide range of cancer cases as well as recipients of organ grafts or immunosuppressive drugs are more vulnerable to infections than the healthy people.The purpose of this study was to determine the prevalence of intestinal parasites in immunosppressive drugs recipients mainly due to cancer and kidney transplantation. Accordingly 385 stool samples of cancer patients and reneal transplantation and also 322 patients who did not receive chemical drugs were collected and examind by Direct Wet Mount, Formalin - Ether concentration Method, Modification of Sheather's Sugar flotation, Modified Ziel – Neelson Stain Technique, Harada- Mori tube and Plate- Agar culture. 34.5% of cases and 28.5% of controls were infected by one or more intestinal parasites. Blastocystis hominis and Giardia lamblia were most prevalent parasites in our study by 18.2% and 11.9% in cases and 11.8% and 6.5% in control group respectively. We found 4 cases of Strongyloidiasis in our patients which might be the causative agent for diarrhea and dissaminated fatal infection in these patients.
