抄録
To determine the extent of genetic diversity of Salmonella choleraesuis subspecies choleraesuis serovar Infantis and whether environmental isolates were similar or identical to human isolates, a total of 110 isolates from humans, broiler samples, egg production facilities, riverwater, sewage, and chicken meat were analyzed epidemiologically by pulsed-field gel electrophoresis. While the isolates showed 35 distinct pulsed-field profiles, none had the genotype of the human isolates. One pulsed-field profile was shared by 43 (39%) of the 110 isolates. These results indicate that relatively fewer clonal lines of S. serovar Infantis had spread widely while multiple clonal lines, including the strain involved in the outbreak, exist in Western Japan.
