Abstract

In Japan, only one outbreak of Salmonella enterica subsp. enterica serovar Chester (S. Chester) has been confirmed in 1999. We performed a single-center retrospective case review of S. Chester infections that occurred in a rural area of Japan in 2016 (n=8). Case 5 and 6 occurred in twin infants who had contact with a pet dog. The dog's stool culture was positive for S. Chester. Pulsed-field gel electrophoresis and cluster analysis of S. Chester strains revealed that all the isolates appeared to be derived from the same genetic clone. Emergence of Salmonella infection can be overlooked if cases are not reported to health authorities; therefore, core hospitals should play a role to alert the occurrence of public health issue.
