摘要: Aims: To examine the variability among environmental Vibrio parahaemolyticus (including trh+ isolates) from Norway, and to compare these clinical isolates imported foods. Methods Results: A total of 246 V. were successfully digested with NotI, fragments separated by pulsed field gel electrophoresis (PFGE). The could be divided into 72 clusters 103 pulsotypes. Eleven clusters contained 4–31 isolates, within greatly varied respect origin. None /or tdh+ clustered trh−/tdh− isolates. included in study belonged two separate clusters. subset was serotyped, great serotype diversity observed parahaemolyticus. O3:K6 O3:KUT, identical or related a pandemic reference strain PFGE. Conclusions: Environmental trh+) genetically diverse, but certain variants occurred throughout coastal environment, some persistent over time. Significance Impact Study: Although persisted Norwegian no evidence indicated that indigenous have caused disease.
