Dissemination of Salmonella enterica subsp. enterica Serovar Typhimurium var. Copenhagen clonal types through a contract heifer-raising operation.
Salmonella enterica subsp. enterica serovar Typhimurium var. Copenhagen isolates from a heifer-raising operation and from 11 dairy herds that had their calves contracted to the heifer-raising operation were examined for their phenotypic and genotypic characteristics. Results of the study showed that the heifer-raising operation could serve as a clearinghouse for Salmonella serovar Typhimurium var. Copenhagen and perhaps other Salmonella serotypes.
