blastocystis homonis

Mahmoud Agholi, Gholam Reza Hatam, Mohammad Hossein Motazedian
Human immunodeficiency virus (HIV) infection has altered both the epidemiology and outcome of enteric opportunistic parasitic infections. This study was done to determine the prevalence and species/genotypes of intestinal coccidian and microsporidial infections among HIV/AIDS patients with diarrhea and/or a history of diarrhea alternately with an asymptomatic interval, and their association with CD4 T cell count. This cross-sectional study was done from May 2010 to May 2011 in Shiraz University of Medical Sciences, South of Iran...

AIM: To provide scientific evidence for prevention and controlling of blastocystosis, the infection of Blastocystis homonis and to study its clinical significance in Huainan City, Anhui Province, China. METHODS: Blastocystis homonis in fresh stools taken from 100 infants, 100 pupils, 100 middle school students and 403 patients with diarrhea was smeared and detected with method of iodine staining and hematoxylin staining. After preliminary direct microscopy, the shape and size of Blastocystis homonis were observed with high power lens...

Blastocystis homonis is a common human parasite of uncertain role in human disease. Approximately equal numbers of reports implicate it and exonerate it as a pathogen. Genetic diversity in B. hominis was investigated using riboprinting to study sequence variation in the small subunit ribosomal RNA genes of 30 randomly selected isolates. Extensive sequence variation was discovered in B. hominis ribosomal RNA genes and this species consists of at least seven morphologically identical but genetically quite distinct organisms...

Several reports have appeared that either support or deny the importance of the protozoan Blastocystis hominis as an intestinal pathogen in humans. In this report, we describe the clinical characteristics of B. hominis and its response to therapy in hospital employees found to have the parasite on routine screening of stools. During the study, 49 patients with B. hominis were identified, and 413 stools were examined from these patients. Twenty-nine patients were asymptomatic (59%), and 20 had symptoms of bloating, flatulence, soft/loose stools, or constipation...
