They comprised 3 cases due to S. typhimurium, 11 cases due to S. enteritidis, 3 cases due to S. thompson, 2 cases due to S. give, 1 case due to S. senftenberg, and 1 case of mixed infection with S. enteritidis and S. thompson.
The frequency distribution of these Salmonella types varied during the five year study, showing a predominance of thompson, give, and senftenberg types of a chicken source with a marked diminution of enteritidis and typhimurium types of a rodent source in the latter half of the period.
