ABSTRACT:   A total of 70 samples of 7 different types of non-processed fruit juices (tamarind, water melon, sugar cane, pine apple, papaya, lime and black agar) and 15 different processed samples were collected randomly from six townships of Yangon from October 2002 to March 2004. All the samples of pine apple, water melon, papaya, sugar cane, and black agar drinks examined in the current study were found to be contaminated with coliforms (100%). In contrast, 40% and 10% of tamarind juice samples were contaminated with coliforms and faecal coliforms respectively. All samples of papaya, sugar cane and black agar juices were contaminated (100%) with faecal coliforms, while pine apple juice showed only 70% contamination. Escherichia coli, Klebsiella aerogenes, Salmonella spp., Shigella boydii, Proteus mirabilis, Vibrio cholerae, Staphylococcus epidermidis and Staphylococcus aureus were isolated and identified from the non-processed soft drinks. However, no bacteria was isolated from lime juice samples. The water that was used for preparation of the drinks was found to be contaminated with bacterial pathogens. The antibiotic susceptibility patterns of the isolated enteropathogenic E. coli (EPEC) showed that they were resistant to ampicillin and carbenicillin (63.64% each), and Vibrio species to ampicillin (80%). Plasmids were isolated from 16 out of 32 E. coli and 14 out of 15 Vibrio species. The size of plasmids was estimatedranging from 20 to 23.13 kilo base pairs.
