Survival of Vibrio Cholerae 01 and 0139 strains in some foods of Yangon

ABSTRACT

The purpose of this study was to determine the survival of Vibrio cholerae 01 and 0139 in foods which are usually offered by street vendors in Yangon. Survival was tested at room temperature (28 degree C-34 degree C) and 4 degree C in melon, mohinga, lethoke and sugar cane juice samples by artifical contamination of food samples. Both Vibrio cholerae 01 and 0139 could survive up to 4 hours at room temperature and up to 24 hours at 4 degree C. The growth was obvious in lethoke and sugar cane juice samples and static in melon and Mohinga samples.
