Antibiotic Susceptibility Profile of Microbes Isolated from Street Food Vended in Chittagong, Bangladesh
Journal Title: International Invention of Scientific Journal - Year 2018, Vol 2, Issue 6
Abstract
The study was conducted to evaluate the antibacterial susceptibility of isolates from street vended foods in five selective areas of Chittagong district, Bangladesh. A total of 200 samples of ready to eat foods-Fucka, Chicken biriani, Sugarcane juice and Egg toast-were aseptically collected. All bacterial isolates were identified by studying their cultural characteristics and biochemical properties. Susceptibility of the isolates to eight (08) antibiotics namely amoxicillin, cephalexin, ceftriaxone, ciprofloxacin, colistinsulphate, gentamicin, oxytetracycline and streptomycin were tested by disk diffusion method. The results illustrated that the high individual and multiple resistances to antibiotics were in Escherichia coli (E. coli) isolates. The most resistant phenotype was against to oxytetracycline, ciprofloxacin, amoxicillin, and streptomycin where resistance to oxytetracycline has approached 100% level for E. coli isolates. In case of E. coli, multi-resistance (resistant to at least four antibiotics) was observed in all sources. Resistance to oxytetracycline was common (80%) in Salmonella spp. isolates and also observed that Staphylococcus aureus resistance to oxytetracycline (55%) and amoxicillin (10%). Besides this, the three isolates from food products having complete sensitivity (100%) to Cephalexin and Gentamicin. Consumption of street food contamination with antibiotic resistant bacteria could be a major threat to public health.
