Abstract:
A
previously identified Shigella flexneri serotype 2a strain was
responsible for an outbreak of shigellosis in a Taiwan township in August 1996. In order to find the relationship between this outbreak
strain and subsequent Shigella infections in the
area, 59, 47, 35, and 20 Shigella isolates recovered in 1997,
1998, 1999, and 2000, respectively, were collected and typed by serological and pulsed-field gel electrophoresis (PFGE) techniques. Of
these 161 isolates, 139 isolates were S. flexneri serotype 2a,
and one-third of them (47 isolates) exhibited the outbreak pattern. The remaining 92 S. flexneri serotype 2a isolates displayed 49
different Not I-PFGE patterns. Forty-five patterns were closely
related to the outbreak pattern, with deletions of three specific Not I fragments occurring with high frequency. While the
outbreak strain remained the main cause of shigellosis after the outbreak, the continuous emergence of closely related though poorly
transmissible strains from the outbreak strain contributed to the observed annual decrease of shigellosis in the
area.
