multilocus sequence typing of campylobacter jejuni isolates from new south wales, australia.multilocus sequence typing (mlst) was used to examine the diversity and population structure of campylobacter jejuni isolates associated with sporadic cases of gastroenteritis in australia, and to compare these isolates with those from elsewhere.200717184329
the response of campylobacter jejuni and campylobacter coli in the sydney rock oyster (crassostrea commercialis), during depuration and storage.sydney rock oysters, when allowed to feed in waters containing approximately 10(4) cfu of campylobacter cells per ml, concentrated between 10(2) and 10(3) cfu of the organism per g of oyster tissue, within 1 h. when these contaminated oysters were subjected to depuration, they were effectively cleaned in 48 h. the survival of campylobacter jejuni and campylobacter coli was also investigated. oysters contaminated by feeding and injection were processed as half shells and bottled oysters and were ...19883275320
an outbreak of infectious hepatitis in commercially reared ostriches associated with campylobacter coli and campylobacter jejuni.a disease causing high morbidity and mortality was observed in young ostriches from six properties in southeast queensland, australia. the disease affected birds from 2-8 weeks of age and was characterised clinically by bright-green urates and pathologically by severe necrotic hepatitis. the liver lesions resembled those of vibrionic hepatitis in other avian species. campylobacter coli was isolated from the livers of affected ostriches from five of the six properties. campylobacter jejuni subsp. ...19989631530
consumption of foods by young children with diagnosed campylobacter infection - a pilot case-control study.to determine whether parentally reported habitual intake of specific foods differed between children with diagnosed campylobacter jejuni infection and children of a comparison group without diagnosed infection.200414972076
reported waterborne outbreaks of gastrointestinal disease in australia are predominantly associated with recreational exposure.to examine the frequency and circumstances of reported waterborne outbreaks of gastroenteritis in australia.201021040184
antibiotic resistance in campylobacter jejuni isolated from humans in the hunter region, new south wales.campylobacter is a common cause of bacterial gastroenteritis in australia. antibiotic resistance among campylobacter is an emerging problem in europe and the united states of america. monitoring may detect emerging resistance. since there is no epidemiologically validated subtyping system for campylobacter, antimicrobial resistance patterns may prove useful as an epidemiological marker. campylobacter isolates from residents of the hunter region were differentiated by pcr into two categories: c. ...200312807280
campylobacter jejuni: incidence in processed broilers and biotype distribution in human and broiler isolates.campylobacter jejuni was isolated from 18 of 40 processed broiler carcasses and 134 of 327 cloacal swabs obtained at four processing plants in sydney, australia. three of four flocks examined carried c. jejuni. eighty-two percent of chicken and 98% of human isolates from the area were of identical biotypes.19827201780
haemolytic-uraemic syndrome in the hunter: public health implications.three cases of haemolytic-uraemic syndrome in the hunter area were reported in february 1995. an investigation was initiated to identify any verocytotoxic escherichia coli in clinical samples that could be associated with the development of the disease. escherichia coli o6:h- and o2:h7 were isolated from case 1. no organisms were identified for case 2, and case 3 samples yielded campylobacter jejuni. in addition, efforts were made to trace sources of any such pathogens in food samples or in the ...19968987212
recovery of viruses and bacteria in waters off bondi beach: a pilot study.a pilot study was conducted between february and april, 1989, on the occurrence of sewage-derived viruses and bacteria in the beach and nearshore waters off bondi, sydney. enteroviruses were isolated from 41% of a total of 66 sewage, sea-water, grease and sediment samples. poliovirus vaccine strains accounted for 78% of the isolates. adenoviruses were isolated four times and coxsackievirus b was isolated twice in samples that were collected away from the bathing area. rotavirus and hepatitis a v ...19892556634
pathogens detected in the faeces of children with diarrhoea in a sydney hospital.during a 54-week period, faecal samples taken from 350 children under 5 years of age, who were admitted with acute diarrhoea to the infectious diseases ward of a sydney hospital, were examined for pathogens. rotavirus was detected as the sole agent in the specimens of 58 patients (16.6%), enteroviruses in those of 26 patients (7.4%), salmonellae in those of 19 patients (5.4%) and campylobacter jejuni in those of 15 patients (4.3%). shigellae were not detected. the results are discussed and, in v ...19846738406
comparison between children treated at home and those requiring hospital admission for rotavirus and other enteric pathogens associated with acute diarrhea in melbourne, australia.the etiology of acute diarrhea in children less than 42 months of age attending one pediatric hospital in melbourne, australia, was studied during a 7-month period encompassing the winter of 1984. pathogens identified in 157 children treated as outpatients with mild disease were compared with those in 232 children hospitalized with severe disease. the pathogens (and frequencies among outpatients and inpatients, respectively) detected were rotaviruses (32.5 and 50.9%), enteric adenoviruses (8.9 a ...19863020082
longitudinal prevalence, faecal shedding and molecular characterisation of campylobacter spp. and salmonella enterica in sheep.faecal excretion of campylobacter spp. and salmonella enterica in sheep in australia was determined using a quantitative multiplex pcr (qpcr) targeting the campylobacter spp. purine biosynthesis gene (pura) and the s.‚ÄČenterica outer membrane protein (ompf). the mutiplex qpcr was specific and campylobacter spp. and s.‚ÄČenterica were each detected with a sensitivity of 5 organisms/µl faecal dna extract. this multiplex qpcr was used to determine the prevalence and concentration of campylobacter spp. ...201425175721
