evidence supporting zoonotic transmission of cryptosporidium in rural new south wales.cryptosporidium hominis, which has an anthroponotic transmission cycle and cryptosporidium parvum, which is zoonotic, are the primary species of cryptosporidium that infect humans. the present study identified the species/genotypes and subgenotypes of cryptosporidium in 7 human and 15 cattle cases of sporadic cryptosporidiosis in rural western nsw during the period from november 2005 to january 2006. the species/genotype of isolates was determined by pcr sequence analysis of the 18s rrna and c. ...200818343369

glycoprotein 60 diversity in c. hominis and c. parvum causing human cryptosporidiosis in nsw, australia.management and control of cryptosporidiosis in human requires knowledge of cryptosporidium species contributing to human disease. markers that are able to provide information below the species level have become important tools for source tracking. using the hypervariable surface antigen, glycoprotein 60 (gp60), c. hominis (n=37) and c. parvum (n=32) isolates from cryptosporidiosis cases in new south wales, australia, were characterised. extensive variation was observed within this locus and the ...200919233175
longitudinal multi-locus molecular characterisation of sporadic australian human clinical cases of cryptosporidiosis from 2005 to 2008.cryptosporidium is a gastrointestinal parasite that is recognised as a significant cause of non-viral diarrhea in both developing and industrialised countries. in the present study, a longitudinal analysis of 248 faecal specimens from australian humans with gastrointestinal symptoms from 2005 to 2008 was conducted. sequence analysis of the 18s rrna gene locus and the 60kda glycoprotein (gp60) gene locus revealed that 195 (78.6%) of the cases were due to infection with cryptosporidium hominis, 49 ...201020206624
evidence of cryptosporidium transmission between cattle and humans in northern new south wales.cryptosporidium is an enteric parasite of public health significance that causes diarrhoeal illness through faecal oral contamination and via water. zoonotic transmission is difficult to determine as most species of cryptosporidium are morphologically identical and can only be differentiated by molecular means. transmission dynamics of cryptosporidium in rural populations were investigated through the collection of 196 faecal samples from diarrheic (scouring) calves on 20 farms and 63 faecal sam ...201222333036
patterns of cryptosporidium oocyst shedding by eastern grey kangaroos inhabiting an australian watershed.the occurrence of cryptosporidium oocysts in feces from a population of wild eastern grey kangaroos inhabiting a protected watershed in sydney, australia, was investigated. over a 2-year period, cryptosporidium oocysts were detected in 239 of the 3,557 (6.7%) eastern grey kangaroo fecal samples tested by using a combined immunomagnetic separation and flow cytometric technique. the prevalence of cryptosporidium in this host population was estimated to range from 0.32% to 28.5%, with peaks occurri ...200516204534
epidemiology of cryptosporidium parvum in symptomatic paediatric oncology patients.although cryptosporidium parvum is known to cause significant morbidity in immunocompromised individuals, including adults with cancer, the epidemiology of this pathogen in paediatric oncology patients is not known.199910404455
