The role of roof rats ( Rattus rattus) in the spread of Salmonella Enteritidis and S. Infantis contamination in layer farms in eastern Japan
SUMMARY The prevalence of Salmonella in four layer farms in eastern Japan was investigated between 2004 and 2006 to determine the role of roof rats ( Rattus rattus ) in the epizootology of Salmonella enterica subsp. enterica serovar Enteritidis ( S . Enteritidis). Persistent S . Enteritidis and S ....
