Bacteriophage typing of Vibrio fluvialis.

Abstract

Six stable bacteriophages of Vibrio fluvialis were isolated from 44 surface water specimens collected in Thailand and Japan. Twelve different phages types were found among 109 V. fluvialis isolated from feces of diarrheal patients and the environment. Seventy-three percent (80/109) of these 109 isolates were typable with these phages. One phage type, designated as A (1) was predominant and accounted for 43% of the V. fluvialis examined. The six bacteriophages used in this typing scheme were stable for at least during a three-month storage at 4 degrees C. This proposed bacteriophage typing scheme may be of valuable aid in tracing sources and routes of infection in outbreaks of V. fluvialis infection in man.
