Identification and antibiogram study of bacteria isolated from different street food
Keywords:street food, antibiotic, resistant, sensitivity, contamination
Food borne diseases are an increasingly recognized problem involving a wide spectrum of illnesses caused by bacterial contamination of food.Microorganism poses potential human health problems and is mainly transmitted through consumption of contaminated foods .Bangladesh is one of the densely populated country where majority of the people consume cheap foods prepared in unlicensed food selling points. The objective of the present study was to investigate the microbiological quality of different street food (Amra, Fusca, Chanachur and Guava) sold by various street vendor at Dinajpur, Bangladesh. A total of 20 samples were collected randomly from street vendors and tested for the presence of bacteria following standard microbiological method used for isolation, enumaration and identification of bacreria. Among the samples all had bacterial contamination. The total viable count (TVC) in diferrent street food samples was ranged from 8.0 × 105 CFU/g to 6.7x107 CFU/g. Among samples Escherichia coli 7(35%), Staphylococcus spp. 6(30%), Klebsiella spp. 5(25%), Salmonella spp. 1(5%) and Shigella spp. 1 (5%) were isolated. Escherichia coli were found highest 3(50%) Amra samples and 2(40%) Guava samples, then another organisms Staphylococcus spp. was found highest 2(50%) Chanachur and 2(40%) Fusca samples and then Klebsiella spp. was found highest 2(40%) Fusca samples. Antibiotic sensitivity test showed that Shigella spp., Staphylococcus spp., Klebsiella spp., Salmonella spp. and Escherichia coli were sensitive to Ciprofloxacin and Salmonella spp. were resistance to Gentamycin. All isolates found resistant to Cefixime, Cefalexin, Erythromycin, Fusidic acid, Cefuroxime and Aztreonam. All of the sample harbor multidrug resistant food borne bacteria which might cause public health hazards if these antibiotic resistance transfer to human.
