| 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 |
| 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 |
| 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-like organisms in gastric biopsies: a christchurch study. | following a 20 patient pilot investigation for campylobacter pyloridis in selected gastric biopsy specimens, 56 consecutive patients subjected to routine gastroscopies were further examined. 14/56 had positive gram stains for spiral gram negative bacilli in gastric biopsy imprints and 4/14 had positive culture for this organism. all 14 positive specimens showed histological gastritis of varying degrees (grade 3 inflammation). the methodology, significance and implications of these findings are d ... | 1986 | 3456109 |
| the epidemiology of campylobacter infections in christchurch 1981-83. | the epidemiology of cases of campylobacter infection in christchurch for 1981-83 is studied. the condition is the most common notifiable disease, occurring mainly in summer and in children under five years and young adults (15 to 35 years). there is evidence to suggest that a rural residence, associated with live animals, or handling raw meat, are risk factors. clearance occurs within two months in 90% of cases. | 1985 | 3857521 |
| a case control study to determine risk factors for campylobacter infection in christchurch in the summer of 1992-3. | this study was designed to determine the risk factors for acquiring campylobacter infection in christchurch in the summer of 1992/3. | 1994 | 7970341 |
| the cost of campylobacteriosis in new zealand in 1995. | to estimate the financial impact of campylobacter infection in canterbury and new zealand in 1995. | 1997 | 9236803 |
| campylobacteriosis in new zealand: results of a case-control study. | to identify and assess the contributions of major risk factors for campylobacteriosis in new zealand. | 1997 | 9519133 |
| the regionality of campylobacteriosis seasonality in new zealand. | new zealand has one of the highest incidences of campylobacteriosis in the developed world, which leads a global trend of increasing notifications of campylobacter infections over the last decade. foodborne and waterborne transmission have been implicated as significant mechanisms in the complex ecology of the disease in new zealand. we examined both regional and temporal variation in notification rates to gain some insight into the role of the new zealand environments in modifying disease incid ... | 2003 | 14594700 |
| 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 |
| 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 |
| 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 |
| microbial groundwater quality and its health implications for a border-strip irrigated dairy farm catchment, south island, new zealand. | intensification of dairying on irrigated pastures has led to concern over the microbial quality of shallow groundwater used for drinking purposes. the effects of intensive dairying and border-strip irrigation on the leaching of e. coli and campylobacter to shallow groundwater were assessed over a three-year period in the waikakahi catchment, canterbury, new zealand. well selection excluded other sources of contamination so that the effect of dairying with border-strip irrigation could be assesse ... | 2008 | 17998609 |
| campylobacters and bacteriophages in the surface waters of canterbury (new zealand). | to determine the relationship between the presence of thermotolerant campylobacters and their bacteriophages (phages) in surface waters for the potential to use phages as an indicator of campylobacter spp. | 2009 | 19187501 |
| counts of campylobacter spp. and prevalence of salmonella associated with new zealand broiler carcasses. | in common with many other countries around the world, the most frequently reported cause of gastrointestinal illness in new zealand is campylobacteriosis. the poultry industry and regulatory agencies are working to address this. similarly, the control of salmonella on poultry has been a focus of industry and regulatory agencies for some time. however, recent data are limited on the prevalence of campylobacter and salmonella on retail chicken products in new zealand. a survey was carried out to d ... | 2008 | 19244909 |
| 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 |
| 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 |
