Abstract
In this study 142 stool samples (64 HIV+/AIDS patients and 78 non-HIV infected individuals) collected from Mazandaran province and screened for intestinal parasites, using direct wet mont, formalin-ether sedimentation concentration, modified Ziehl Neelsen and modified trichrome techniques. Each person in this study was examined for CD4+ counts. Intestinal parasites were found in 11/64 (17.2%) of patients in HIV+/AIDS group and in 14/78 (17.9%) of controls. Prevalence of parasites detected in HIV+/AIDS individuals was as follow: Cryptosporidium sp. 9.4%, Giardia lamblia 3.1%, Entamoeba coli 1.6%, E. histolytica 1.6% and Chilomastix mesnili 1.6%. Prevalence of parasites in controls was as follow: Trichostrongylus sp. 6.4%, G. lamblia 3.8%, Cryptosporidium sp. 2.5%, E. coli 2.5%, E. histolytica 1.2%, Hookworms 1.2%. The mean of CD4+ counts in HIV-positive group (430 cells microL(-1)) was remarkedly less than controls (871 cells microL(-1)) (p = 0.001). As patients usually belong to poor socio-economic backgrounds and they can hardly afford treatment, therefore, it is suggested screening and free treatment of intestinal parasites in these individuals should be taken by health centers to prevent the occurrence of these diseases in HIV+/AIDS patients, as often the disease may take a fulminant form.
