| campylobacter monitoring in german broiler flocks: an explorative time series analysis. | campylobacter, a major zoonotic pathogen, displays seasonality in poultry and in humans. in order to identify temporal patterns in the prevalence of thermophilic campylobacter spp. in a voluntary monitoring programme in broiler flocks in germany and in the reported human incidence, time series methods were used. the data originated between may 2004 and june 2007. by the use of seasonal decomposition, autocorrelation and cross-correlation functions, it could be shown that an annual seasonality is ... | 2009 | 18811672 |
| enterococcus faecium strains with vana-mediated high-level glycopeptide resistance isolated from animal foodstuffs and fecal samples of humans in the community. | the occurrence and the further spread of high-level glycopeptide-resistant, vana-positive enterococcus faecium strains outside of hospitals have been investigated. we could isolate such bacteria directly from thawing liquids of commercially produced frozen poultry (chickens, turkeys; no further data on previous feeding with avoparcin were available). in 5 of 13 samples of raw minced meat of pigs originating from 13 different butcher's shops, glycopeptide-resistant e. faecium (vana type) could be ... | 1995 | 9158786 |
| [prevalence of motile salmonellae in egg-laying hens at the end of the laying period]. | a total of 3504 hens of the layer-type from 122 flocks (belonging to 89 farms), each with more than 10,000 animals, were culturally examined at the time of slaughter. of these hens, 2112 (60.3%) from 74 flocks (60.7%) were obtained from 21.3% of the laying-hen farms in a selected region of lower saxony in germany. the other hens came from the remaining part of lower saxony and seven other german states (brandenburg, mecklenburg vorpommern, north rhine westphalia, schleswig holstein, saxony, saxo ... | 1996 | 8919966 |
| establishment of gastro-intestinal helminth infections in free-range chickens: a longitudinal on farm study. | the objective of this study was to monitor establishment and development of gastro-intestinal helminth infections in chickens over two production years (py) on a free-range farm in lower saxony, germany. the data were collected between july 2010 and june 2011 (py1) and july 2011 and january 2013 (py2), respectively. during py1, lohmann brown classic (lb classic, n = 450) was tested, while in py2 two different genotypes (230 lb classic, 230 lb plus) were used. the hens were kept in two mobile sta ... | 2014 | 25080825 |
| epidemiology of influences on the performance in broiler flocks--a field study in germany. | to establish which factors influence performance and bird welfare during a fattening period and to identify those factors to be investigated during routine monitoring of farms by veterinary authorities, a questionnaire-based field study was conducted in districts of lower saxony, germany, with the highest density of broiler chickens. mortality and bw of farms with different stocking densities (≤33, 33.1-39, and >39 kg/m(2)) were investigated. analyses of 79 farms with 176 stables and 634 fatteni ... | 2013 | 24046403 |
| risk factors associated with sporadic salmonellosis in adults: a case-control study. | in order to identify and assess recent risk factors for sporadic human infections with salmonella enterica, we conducted a case-control study in lower saxony, germany. the data collection was based on standardized telephone interviews with 1017 cases and 346 controls aged >14 years. odds ratios were calculated in single-factor and multi-factor analyses for salmonella cases and two different control groups, i.e. population controls and controls with rotavirus infection. multi-factor analysis reve ... | 2013 | 22717173 |
