Isolation of Salmonella using pooled pen feces from 37 U.S. swine farms

摘要

The purpose of this study was to culture the pooled pen feces of market weight pigs to determine the most common Salmonella serotypes being shed and to see if farms positive by culture were also positive by serology. Isolates were analyzed to determine if they had Oantigens capable of inducing an immune response detectable by the Danish Mix-ELISA. There were a total of 286 isolates of Salmonella recovered, 263 of which shared O-antigens with the Mix-ELISA.
