| serological survey of exposure to erysipelothrix rhusiopathiae in poultry in new zealand. | abstract aims: to estimate the seroprevalence of antibodies to erysipelothrix rhusiopathiae in chickens in new zealand, and to estimate the effect of housing type, geographical location and age on seroprevalence. methods: a cross-sectional serological survey of a convenience sample of 545 broiler, breeder, and layer chickens in 55 flocks was conducted in 2010-2011. birds were aged 5-83 weeks; housing types were free-range, shed, caged, and unknown; and flocks were located in the auckland, ma ... | 2011 | 22224872 |
| 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 |
| 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 |
| 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 |
| application of molecular epidemiology to understanding campylobacteriosis in the canterbury region of new zealand. | pulsed-field gel electrophoresis genotypes of campylobacter isolates from 603 human patients were compared with 485 isolates from retail offal (primarily chicken and lamb) to identify temporal clusters and possible sources of campylobacteriosis. detailed epidemiological information was collected from 364 of the patients, and when combined with genotyping data allowed a putative transmission pathway of campylobacteriosis to be assigned for 88% of patients. the sources of infection were 47% food, ... | 2013 | 22906314 |
| 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 |
| 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 |
