Human immunodeficiency virus (HIV)-infected persons are commonly infected with species and in both developed and developing countries, particularly patients with CD4+ cell counts below 200 cells/μL; 285 HIV-infected patients on highly active antiretroviral therapy (HAART) were enrolled in this study, and both stool and blood specimens were collected from participants. The stool specimens were analyzed and typed for and spp. by polymerase chain reaction (PCR) and DNA sequencing. CD4 count was analyzed using flow cytometry. and were detected in 18 (6.3%) and 4 (1.4%) patients, respectively. The detected mostly belonged to a new genotype group that, thus far, has only been found in a few humans: genotype Nig4 in 2 patients and two new genotypes related to Nig4 in 12 patients. The detected included (two patients), (one patient), and (one patient), with the two infections belonging to an unusual subtype family. Additional studies are required to determine whether some genotypes and subtypes are more prevalent in HIV patients on HAART.
