Objective To understand the infection status of opportunistic pathogenic protozoa in HIV-infected patients in Menglian County, Yunnan Province. Methods Forty-six HIV-positive cases in Menglian County were randomly sampled. Questionnaires were collected from households and fresh stool samples were collected. Cytodiquins of Giardia lamblia were examined by direct smear Lugol’s iodine staining, Acid Dye Test for Cryptosporidium Oocysts.
