brief note. campylobacter jejuni gastroenteritis in brisbane. 1979460954
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
low-level fluoroquinolone resistance among campylobacter jejuni isolates in australia.ciprofloxacin-resistant campylobacter jejuni isolates obtained from infected patients in australia have not been detected in studies of isolates from specific geographic areas. the australian government has prohibited the use of fluoroquinolone in food-producing animals. to assess the impact of this policy, we have examined the antimicrobial susceptibility of isolates from 5 australian states.200616619147
real-time pcr detection of pathogenic microorganisms in roof-harvested rainwater in southeast queensland, australia.in this study, the microbiological quality of roof-harvested rainwater was assessed by monitoring the concentrations of escherichia coli, enterococci, clostridium perfringens, and bacteroides spp. in rainwater obtained from tanks in southeast queensland, australia. samples were also tested using real-time pcr (with sybr green i dye) for the presence of potential pathogenic microorganisms. of the 27 rainwater samples tested, 17 (63%), 21 (78%), 13 (48%), and 24 (89%) were positive for e. coli, en ...200818621865
implications of faecal indicator bacteria for the microbiological assessment of roof-harvested rainwater quality in southeast queensland, australia.the study aimed to evaluate the suitability of escherichia coli, enterococci, and clostridium perfringens for assessing the microbiological quality of roof-harvested rainwater and assessing whether the concentrations of these faecal indicators can be used to predict the presence or absence of specific zoonotic bacterial or protozoan pathogens. from a total of 100 samples tested, 58%, 83%, and 46% of samples were found to be positive for, respectively, e. coli, enterococci, and clostridium perfri ...201020657617
human and bovine adenoviruses for the detection of source-specific fecal pollution in coastal waters in australia.in this study, the host-specificity and -sensitivity of human- and bovine-specific adenoviruses (hs-avs and bs-avs) were evaluated by testing wastewater/fecal samples from various animal species in southeast, queensland, australia. the overall specificity and sensitivity of the hs-avs marker were 1.0 and 0.78, respectively. these figures for the bs-avs were 1.0 and 0.73, respectively. twenty environmental water samples were collected during wet conditions and 20 samples were colleted during dry ...201020891037
health risk from the use of roof-harvested rainwater in southeast queensland, australia, as potable or nonpotable water, determined using quantitative microbial risk assessment.a total of 214 rainwater samples from 82 tanks were collected in urban southeast queensland (seq) in australia and analyzed for the presence and numbers of zoonotic bacterial and protozoal pathogens using binary pcr and quantitative pcr (qpcr). quantitative microbial risk assessment (qmra) analysis was used to quantify the risk of infection associated with the exposure to potential pathogens from roof-harvested rainwater used as potable or nonpotable water. of the 214 samples tested, 10.7%, 9.8% ...201020851954
antibiotic resistance in campylobacter jejuni and campylobacter coli isolated from poultry in the south-east queensland region.the aim of this study was to determine the antimicrobial resistance patterns of 125 campylobacter jejuni and 27 campylobacter coli isolates from 39 queensland broiler farms.200717392353
isolation of campylobacter jejuni from poultry carcases.campylobacter jejuni was isolated from 94% of chicken carcase rinses collected in a queensland poultry abattoir. direct plating resulted in the isolation of the organism from 84% of the rinses. a further 10% were found to contain c. jejuni by a procedure of selective enrichment and membrane filtration. counts of c. jejuni on the carcases ranged from 0 to 1.1 x 10(5) organisms per carcase.19817342935
