Prevalence and potential risk factors for the occurrence of cefotaxime resistant Escherichia coli in German fattening pig farms—A cross-sectional study

摘要: A cross-sectional study concerning farm prevalence and risk factors for the count of cefotaxime resistant Escherichia coli (E. coli) (CREC) positive samples per sampling group on German fattening pig farms was performed in 2011 2012. Altogether 48 four agricultural regions whole Germany were investigated. Faecal samples, boot swabs dust from two groups taken supplemental data collected using a questionnaire. On 85% farms, at least one sample contained E. colonies. Positive more frequent faeces (61%) (54%) than (11%). Relevant variables questionnaire analysed univariable mixed effect Poisson regression model. Variables that related to number (risk) with p-value <0.2 entered multivariable This model reduced statistically significant via backward selection. Factors increased involved management hygienic aspects. Farms had separate pen diseased pigs 2.8 higher mean (95%-CI [1.71; 4.58], p=0.001) without an extra pen. The under-floor exhaust ventilation compared over floor (2.22 [1.43; 3.46], observed controlled flies toxin did not (1.86 [1.24; 2.78], p=0.003). It can be concluded, CREC are wide spread farms. In addition explorative approach present suggests influence strategies occurrence coli.
