Prevalence and Antibiogram Profiling of Rotten Fruits from Different Areas of Dhaka City, Bangladesh

Fruits are highly nutritious, sources of vitamins, minerals, fibers etc. and these are part of our daily diet. However, during cultivation, harvesting, transportation, handling fruits get contaminated with pathogenic microorganisms which leads to severe problems to community. Owning to this point, in current research, bacteriological analysis was performed on Sofeda, Pineapple, Grape, Banana, Apple, Orange, Guava, papaya, Jujube and Starfruit. Total 50 samples were randomly collected from market and street vendors of Dhaka city. Higher numbers of rotten fruits were present in wholesale markets. 35 strains were isolated which included Salmonella spp., Acinetobacter spp., Klebsiella spp., Vibrio cholerae, Vibrio parahaemolyticus, Staphylocoous aureus and E. coli. They were identified using biochemical test and antibiogram for selective isolates. In case of drug resistance of isolates, majority exhibited resistance against Erythromycin, Vancomycin and Amoxycillin and showing sensitivity against Ciprofloxacin and Ceftriaxone. It was observed in the current study that 100% isolates were resistant against Erythromycin, followed by Amoxycillin 90.63% and vancomycin 86.25%, where only 35.27% isolates were resistant against Ciprofloxacin. In case of sensitivity 64.73% isolates were sensitive against Ciprofloxacin followed by Ceftriaxone 66.25%.
