Vibrio parahaemolyticus diarrhea, Chile, 1998 and 2004

Abstract

Analysis of clinical isolates of Vibrio parahaemolyticus from outbreaks in Chile in the cities of Puerto Montt in 2004 and Antofagasta in 1998 indicated that 23 of 24 isolates from Puerto Montt and 19 of 20 from Antofagasta belonged to the pandemic clonal complex that emerged in Southeast Asia in 1996.

Figure

Representative arbitrarily primed polymerase chain reaction (AP-PCR) patterns for Vibrio parahaemolyticus DNA from strains of the outbreaks in Chile and Southeast Asia and dendrogram illustrating the clustering of the patterns by similarity. The percentage of similarity is shown above the dendrogram. A and B are AP-PCR with primers P1 and P3, respectively. The corresponding isolates are indicated on the right. PMC and ATC correspond to isolates from the outbreaks in Puerto Montt and Antofagasta, respectively. VpD, VpKX, VpAQ and VpI correspond to culture collection strains ATCC17802T, RIMD2210633, RIMD 2210856, and RIMD 2210086, respectively. 97LVp2 and Vp81 correspond to strains obtained from Mitsuaki Nishibuchi of the Center for Southeast Asian Studies, Kyoto University.
