ABSTRACT
Objective To investigate the Cryptosporidium infection and its epidemiological characteristics in HIV/AIDS patients with chronic diarrhea. Methods Stool samples collected from HIV/AIDS confirmed patients with chronic diarrhea who lived in Beijing, Henan and Xinjiang.Samples were concentrated by Formalin-Ethyl Acetate Sedimentation technique and stained by modified acid-fast stain (AFS) for the identification of oocysts by microscopy. CD4+T cells count was performed by Flow Cytometry. Results The overall infection rate of Cryptosporidium in AIDS patients was 12.6%(32/253). The infection rates of oocysts in the area of Beijing, Henan and Xinjiangwere 5.97% ( 4/67 ), 16.1% (24/149 ) and 1 0.8% (4/37) respectively. The infection rate of oocysts in the urban areas was 6.5%(7/104) while in the countryside it was 16.8%(25/149) and the difference was significantly different. However, there were no any differences discovered between the infection rates on patient' s gender or on infection occurred in different seasons. The infectious rates of ooeyst in patients on different stages of the disease were also significantly different (P<0.01). Conclusion AIDS patients infected by Cryptosporidium were not rarely seen in northern China. The rate of infection was not associated with patient' s gender but was associated with patient' s living environments. Patients living in the countryside, with lower lever of CD4 +T cells counts and at the middle/late stage of the disease, Cryptosporidium infection appeared to be high.
