Evaluation of the BBL Crystal Enteric/Nonfermenter kit for the identification of water-derived environmental Enterobacteriaceae.

abstract：:Fattening pigs are often infected with campylobacter. To eliminate campylobacter from the pig population, a top-down approach, involving the breeding and reproduction farms, seems appropriate. In order to investigate the effectiveness of a top-down approach, sows' faeces from the following farms were analysed for the ...
