cryptosporidium in 100 australian children. | over a consecutive 36 month period, 100 patients out of 6,980 (1.4%) from whom stool samples were examined had oocysts of cryptosporidium detected on fecal microscopy. three patients were receiving cytotoxic chemotherapy and adequate clinical information was available from 84 of the remainder. fifty per cent of patients were aged 1 to 2 years, 29% were less than 12 months and the rest were more than 2 years of age. more than one-quarter of the patients were australian aborigines. isolations of c ... | 1992 | 1523466 |
giardiasis in nsw: identification of giardia duodenalis assemblages contributing to human and cattle cases, and an epidemiological assessment of sporadic human giardiasis. | two genetic assemblages (a and b) of the protozoan parasite species, giardia duodenalis, infect humans, domestic animals and wildlife. in new south wales, australia, over 2000 sporadic human giardiasis cases are reported annually, but parasite sources and links between sporadic cases are unknown. this study describes g. duodenalis assemblages contributing to human and cattle cases in nsw, and examines demographic, spatial, and temporal distributions of nsw human infections and g. duodenalis asse ... | 2016 | 27370572 |
rapid identification of giardia duodenalis assemblages in nsw using terminal-restriction fragment length polymorphism. | humans are infected by 2 genetic assemblages (a and b) of giardia duodenalis, a protozoan parasite that causes gastro-intestinal disease. sub-assemblages ai, aii, biii and biv are commonly identified in human cases. detection requires amplification of g. duodenalis loci. subsequent dna sequencing or restriction fragment length polymorphism (rflp) identifies sub-assemblages but is expensive (dna sequencing) or insensitive (rflp). this study investigated a fluorescence-based detection method, usin ... | 2012 | 22417457 |
high prevalence giardia duodenalis assemblage b and potentially zoonotic subtypes in sporadic human cases in western australia. | giardia duodenalis is a widespread parasite of mammalian species, including humans. fecal samples from sporadic human clinical cases of giardiasis in western australia were analysed at two loci; 18s rrna and glutamate dehydrogenase (gdh), and g. duodenalis assemblage b isolates were identified in 75% of isolates. sequence analyses of 124 isolates at the 18s rrna locus identified 93 isolates as assemblage b and 31 as assemblage a. analyses of 109 isolates at the gdh locus identified 44 as b3, 38 ... | 2010 | 19703458 |
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 ... | 1991 | 1958719 |
a health and social survey of a group of children from rural new south wales. | between the middle of may and middle of july, 1972, 177 children aged up to 15 years were admitted to a nursing home in sydney on referral from their doctors in country areas of new south wales for specialized investigation and treatment mainly of respiratory infections, congenital malformations and orthopaedic and ophthalmic conditions. specimens of faeces from these children were examined for bacterial pathogens and parasites. these tests revealed the presence of intestinal parasites (mostly g ... | 1975 | 1160771 |
