population-based comparative study of campylobacter and salmonella enteritis in south australia.a total of 658 cases of campylobacter enteritis was reported in south australia in the 18 months from march, 1980. although campylobacter sp. may cause more gastrointestinal disease than salmonella sp. during some time periods, our data suggest that the reverse applies over all. however, since campylobacter enteritis tends to affect older persons who possibly are investigated less frequently, the relative prevalence of campylobacter infection may have been understated. both diseases are notified ...19827132864
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
campylobacter: common cause of enteritis in an infectious diseases hospital.eleven patients were referred to the infectious diseases wards of the prince henry hospital, sydney, between august and december, 1979, with acute infectious diarrhoea acquired within australia. nine of the 11 had infection with campylobacter species as the sole pathogens. in contrast, a variety of pathogens was isolated from the stools of 13 patients referred to the hospital with enteritis acquired during overseas travel, including three shigella species, but only one campylobacter species. the ...19807432313
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
a study of the foodborne pathogens: campylobacter, listeria and yersinia, in faeces from slaughter-age cattle and sheep in a study of faeces from 475 slaughter-age cattle and sheep from 19 herds or flocks, campylobacter species (c. jejuni and c. coli) were cultured from all production systems studied and from 73.7 per cent (14/19) of herds or flocks. within individual properties there was a higher prevalence in cattle than in sheep, with campylobacter being most commonly isolated from feedlot cattle. the median prevalences and ranges were: for dairy cattle, six per cent (0-24%), feedlot beef cattle, 58 per cent ( ...200312926738
antimicrobial resistance in campylobacter spp., escherichia coli and enterococci associated with pigs in australia.the major influences on the amplification and spread of antibiotic-resistant bacteria are the therapeutic use of antibiotics in human medicine and their use in livestock for therapy, prophylaxis and growth promotion. the use of veterinary antibiotics has many benefits to the livestock industries ensuring animal health and welfare, but use at subtherapeutic levels also exerts great selective pressure on emergence of resistant bacteria. the possible effect on human health is a problem of current d ...200415330980
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
higher rate of culture-confirmed campylobacter infections in australia than in the usa: is this due to differences in healthcare-seeking behaviour or stool culture frequency?laboratory-based surveillance by ozfoodnet in australia and foodnet in the usa indicated that the incidence of campylobacter infections in 2001 in australia was about nine times higher than in the usa. we assessed whether this disparity could be explained by differences in the frequency of stool culturing. using data from population surveys of diarrhoea and symptom profiles for campylobacter from case-control studies, indices of healthcare behaviour taking into account the severity of campylobac ...200919493375

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
risk factors for campylobacter infection in infants and young children: a matched case-control study.campylobacter infection has one of the highest rates of all the notifiable diseases in australia, with a peak in children aged 0-35 months. a matched case-control study was conducted to investigate risk factors for campylobacter infection for children in this age group. eighty-one cases and 144 controls were enrolled in the study that was conducted between 24 january 1996 and 21 january 1997. the following risk factors were found to be independently associated with illness: ownership of pet pupp ...200111811871
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
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
increased incidence of campylobacter pylori infection in gastroenterologists: further evidence to support person-to-person transmission of c. pylori.the mode transmission of campylobacter pylori is still unknown, although several studies have suggested person-to-person transmission. in this study the incidence of active c. pylori infection in an endoscopy staff was compared with that in general practitioners and normal blood donors. since endoscopy workers are in close contact with patients, many of whom would be likely to have active c. pylori infection, it was likely that there would be an increased incidence of active c. pylori infection ...19892789427
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
Campylobacteriosis rates show age-related static bimodal and seasonality trends.Campylobacteriosis is highly characterised by a strongly seasonal rate of incidence. Age is also known to be a risk factor for sporadic campylobacteriosis, but little has been done to quantify age-related rates of campylobacteriosis. This study investigates age-related incidence across countries and up to 12 years of data, as well as differences in seasonality within age groups.201121946876
