Abstract
Abstract:The research work was conducted for isolation and identification of potential pathogenic bacteria from blow fly (Calliphoraspp.) and to investigate their antibiotic susceptibility. For this purpose, 20 blow flies were collected from 4 selected areas (Curzon Hall, Dhaka Medical College Hospital, Fruit Store and Fish Market) of Dhaka city. A total of 40 samples (20 from external surface and 20 from alimentary gut homogenates) were prepared from the blow flies. Among the total 20 flies, 3(15%) were collected from Curzon Hall and 5(12.5%) isolates were obtained from them; 6(30%) flies were collected from DMCH which had 11(27.5%) isolates; 5(25%) flies were collected from fruit stores and 10(25%) isolates were collected from there; 6(30%) flies were collected from fish market and 14(35%) isolates were collected from there. The isolated bacteria were identified as E.coli, 12 (30%); Salmonella spp., 8 (20%); Shigella spp., 4(10%); Enterobacter spp., 3 (7.5%);Klebsiella spp., 2 (5%); Bacillus spp., 7 (17.5%) and Staphylococcus spp., 4 (10%) in number whichbased on morphology as observed under microscope as well as cultural and biochemical properties.All of these isolates wereresistant to various antibiotics. Antibiotic resistance of these species affect our human healthalso. This study demonstrated the potential of blow flies as a vector of variouspathogenic microorganisms and a mode of transmission of antibiotic resistance.
