Abstract

Vf33 is a filamentous bacteriophage isolated from Vibrio parahaemolyticus. We performed Southern blot hybridization analysis to examine the distribution of Vf33-related genetic elements in the pandemic strains (O3:K6 strains isolated between 1995 and 1997, O4:K68 and O1:K untypeable strains isolated between 1997 and 1999) of V. parahaemolyticus. Nucleotide sequences homologous to the Vf33 DNA were detected in all 57 test strains including pandemic and non-pandemic strains. However, the profiles of hybridization, including the restriction fragment length polymorphism, with nine Vf33-derived DNA probes exhibited by the pandemic strains were identical and were different from those by the non-pandemic strains. The results support the hypothesis that the pandemic strains are clonal, and suggest a possibility that they have acquired (a) new gene(s) via a Vf33-like filamentous phage.
