Abstract

<i>Vibrio parahaemolyticus</i>O3:K6 Epidemic Diarrhea, Chile, 2005

Highlights

  • To the Editor: Outbreaks of diarrhea and gastroenteritis caused by Vibrio parahaemolyticus have been recently reported in many countries and regions where this pathogen was previously unknown [1,2]

  • Pulsed-field gel electrophoresis confirmed that V. parahaemolyticus strains isolated from patients throughout the epidemic corresponded to pandemic clone O3:K6, as did the strains isolated in Chile from 2 smaller outbreaks in 1998 and 2004 [1,8]

  • Strains of this clone constituted the only pathogenic strain of V. parahaemolyticus detected in mussels and the only pathogenic strain that has persisted in shellfish throughout this period [1,8]

Summary

Introduction

To the Editor: Outbreaks of diarrhea and gastroenteritis caused by Vibrio parahaemolyticus have been recently reported in many countries and regions where this pathogen was previously unknown [1,2]. Pulsed-field gel electrophoresis confirmed that V. parahaemolyticus strains isolated from patients throughout the epidemic corresponded to pandemic clone O3:K6, as did the strains isolated in Chile from 2 smaller outbreaks in 1998 and 2004 [1,8]. Strains of this clone constituted the only pathogenic strain of V. parahaemolyticus detected in mussels and the only pathogenic strain that has persisted in shellfish throughout this period [1,8].
