Vibrio cholerae are the causative agents of cholera, an acute dehydrating diarrhea. The research report was designed for isolation and identification of Vibrio cholerae from juices. A total of forty samples of different fruit juices such as orange, papaya, grape, malta, sugarcane juice, lemon juice, aloe vera and isupgul juice were collected from different areas of Dhaka city. The total viable count was varying from 7.73 x104-7.62 x108 cfu/ml where the highest count observed in sugarcane juice and lowest count in orange juice. In case of fungal count range was 2.7 x102 – 4.9 x105 cfu/ml. Total coliform count was between 11 – >2400/ 100 ml and E. coli count between <3 – 120/100 ml. Vibrio cholerae was present in 20% of samples where the 75% of Vibrio cholerae were detected from sugarcane juice which was also contaminated with high bacterial and fungal load. The occurrence of drug resistance was also determined in the 8 isolated Vibrio cholerae. All the isolates were resistant to polymixin B, and sensitive to gentamycin and ciprofloxacin. About 40% isolates were resistant to tetracycline and neomycin and 80% isolates were resistant to amikacin. Plasmid profiling of eight isolates also performed, where most of the strain harbor two plasmids. With all the investigation it is bearing on mind that Vibrio cholerae cause severe diarrhoea and occurance of Vibrio cholerae in juice may cause a serious health hazards.

Key words: Plasmid, Vibrio cholera, coliform, E. coli, fruit juice, Bangladesh
