the prevalence and genetic diversity of campylobacter spp. in domestic 'backyard' poultry in canterbury, new zealand.	campylobacteriosis is the most commonly notified illness in new zealand. whilst the importance of commercial poultry in campylobacteriosis is well established, little is known about the possible role of chickens kept at home as a direct animal/faecal contact or consumption exposure pathway. the aim of this study was to determine the prevalence and genetic diversity of campylobacter spp. in domestic backyard chicken flocks in the canterbury region of new zealand. poultry faecal samples were colle ...	2011	21824372
microbial transport from dairying under two spray-irrigation systems in canterbury, new zealand.	transport through the soil and vadose zone to groundwater of escherichia coli, fecal coliforms, and campylobacter spp. from pasturing of dairy cows was studied on two working dairy farms under a traveling irrigator and a center pivot system. leachate was collected from 1.5 m depth using a large linear lysimeter over a period of 4 yr after rainfall or irrigation applied using a traveling irrigator. there was little transport of fecal coliforms or campylobacter from irrigation applications of 55 m ...	2010	20400578
application of pulsed-field gel electrophoresis to identify potential outbreaks of campylobacteriosis in new zealand.	since 2002, new zealand's incidence of campylobacteriosis has exceeded 300 cases per 100,000 people per annum. to evaluate genetic variation in human isolates, 183 campylobacter isolates were collected from a single clinical laboratory in christchurch: 77 during an 8-week period in spring, and the rest 3 months later over a second 8-week period in autumn. isolates were identified to the species level and subtyped using penner serotyping (campylobacter jejuni only) and pulsed-field gel electropho ...	2006	16455892
outbreak of campylobacteriosis following pre-cooked sausage consumption.	a small outbreak of campylobacteriosis involving three cases was investigated in terms of campylobacter types present in the suspect food (pre-cooked sausages) and clinical samples from the cases.	2005	16366058
characterization of erythromycin resistance in campylobacter coli and campylobacter jejuni isolated from pig offal in new zealand.	to determine the level and mechanism(s) of antimicrobial resistance in campylobacter isolates obtained from human and environmental sources from south canterbury, new zealand.	2004	15186451
a further study of the epidemiology of campylobacter jejuni infections.	epidemiological data on notifications of campylobacter jejuni infections is given for the christchurch health district area. the number of notifications rose steadily to a peak of 883 cases in 1987 (rate 261 per 100,000 population). christchurch shows consistently higher rates than the rest of new zealand. peak incidence is in the 0-4 age group; there is a high incidence amongst males and in rural areas; peak incidences in spring/summer; occupational risks have not been identified; chicken consu ...	1990	2342690
campylobacter enteritis--new zealand, 1990.	in august-september 1990, an outbreak of campylobacter enteritis occurred at a camp near christchurch, new zealand. this report provides a preliminary summary of the investigation of this outbreak by the new zealand communicable disease centre and the canterbury area health board.	1991	1899467
waterborne outbreak of campylobacter jejuni in christchurch: the importance of a combined epidemiologic and microbiologic investigation.	campylobacter is a common cause of gastroenteritis in new zealand; however, the source of infection usually remains unknown. reports of two cases of campylobacter jejuni enteritis at a camp and convention centre near christchurch were investigated. through interviews of persons living at or attending the camp, 42 additional cases were identified. epidemiologic and microbiologic data strongly suggested the water supply as the source of infection. the combined epidemiologic and microbiologic inves ...	1991	1891134
