factors associated with the detection of entamoeba histolytica in homosexual men.in a study of bowel parasites in 128 australian homosexual men attending a sexually transmitted diseases (std) clinic, entamoeba histolytica was detected in 37%, giardia intestinalis in 3% and at least one protozoan in 81% of the group. there was no evidence of pathogenicity of e. histolytica, nor was there any association between the detection of e. histolytica and sexual practices, gastrointestinal symptoms, proctitis, human immunodeficiency virus antibody result or t-cell subset values. howev ...19911958719
comparison of stool antigen detection kits to pcr for diagnosis of amebiasis.the present study was conducted to compare two stool antigen detection kits with pcr for the diagnosis of entamoeba histolytica infections by using fecal specimens submitted to the department of microbiology at st. vincent's hospital, sydney, and the institute of medical and veterinary science, adelaide, australia. a total of 279 stool samples containing the e complex (e. histolytica, entamoeba dispar, and entamoeba moshkovskii) were included in this study. the stool specimens were tested by usi ...200818367563
entamoeba moshkovskii infections in sydney, australia.entamoeba moshkovskii is considered to be a free-living ameba, which is morphologically similar, but biochemically and genetically different, to entamoeba histolytica and entamoeba dispar. however, recent studies have suggested that e. moshkovskii may be a "potential" pathogen, with infections giving rise to diarrhea and other intestinal disorders. microscopy and polymerase chain reaction (pcr) targeting the 18s ribosomal (r) dna was performed on fecal samples collected from patients presenting ...200817957394
invasive amebiasis in men who have sex with men, australia.entamoeba histolytica is a pathogenic ameba that has recently been recognized as an emerging pathogen in men who have sex with men (msm) in asia-pacific countries where it is not endemic, i.e., japan, taiwan, and republic of korea. we report locally acquired invasive amebiasis in sydney, australia, exclusively in msm.200818598643
pcr detection of entamoeba histolytica, entamoeba dispar, and entamoeba moshkovskii in stool samples from sydney, australia.this study investigated the presence of entamoeba histolytica, entamoeba dispar, and entamoeba moshkovskii in stool samples from a patient population in sydney, australia. stool samples were tested by microscopy and pcr. five patients were found with e. histolytica infections, while e. dispar and e. moshkovskii were observed in 63 (70.8%) and 55 (61.8%) patients, respectively, by pcr. this is the first study in australia using molecular techniques to determine the presence of e. histolytica, e. ...200717229864
seroprevalence of entamoeba histolytica infection among men who have sex with men in sydney, australia.a retrospective analysis was undertaken to determine the seroprevalence of entamoeba histolytica infection in sydney, australia. using an enzyme-linked immunosorbent assay, 429 high risk human immunodeficiency virus (hiv)-infected men who have sex with men (msm), 446 low risk hiv-uninfected msm, and 456 hiv-uninfected controls were assessed. seroprevalence rates were 5.13% for the high risk hiv-infected msm group, 0.22% for the low risk hiv-uninfected msm group, and 0.44% for the control group. ...201020889891
