Evaluation of Antibiotic Sensitivity Against Bacterial Diseases Prevalent in Commercial Poultry Farm in Western Part of Bangladesh

A surge in the emergence and spread of antimicrobial resistance (AMR) has become a major concern. The indiscriminate use of antibiotics in poultry farming, increased consumption of poultry products containing antimicrobial residues is likely to hasten the development of multidrug resistance in pathogens, as well as in commensal organisms. To substantiate our knowledge on the status of AMR to the Neomycin, Gentamicin, Levofloxacin, Ciprofloxacin, Doxycycline, Sulfonamide, Amoxicillin and Cephalexin, commonly being used in poultry farms in Rajshahi city (Western Part) of Bangladesh a cross sectional study was carried out using conventional Kirby-Bauer disc diffusion technique. We tried to identify sensitivity of the stated antibiotics against bacterial samples obtained from 30 liver samples of live birds out of which 24 were layer and 6 were broiler from 10 commercial poultry farms. In our study, we observed that Cephalexin, Neomycin, Gentamicin and Levofloxacin retain superior antimicrobial potency at the rate of 33.33%, 23.33%, 20%, and 23.33% respectively. Moreover, Levofloxacin started to show quite (70%) to moderate (6.67%) sensitivity and Neomycin (76.67%), Gentamicin (80%) Cephalexin (33.33%) show only quite sensitivity indicating exacerbation of existing antimicrobial resistance through gradually losing their affectivity against microbial infections. On the other hand, during our observation Ciprofloxacin (33.33%), Amoxicillin (20%), Doxycycline (6.67%) and Sulfonamides (3.33%) were found having no sensitivity at all, however, these drugs still being considered as drug of choice for commercial flocks to treat microbial infection. Farmers ‘knowledge, attitudes, and practices regarding the use of antibiotics have to be fully compliant in line with manufacturers’ recommendations to reduce risk to public health. This study was, therefore, conducted to collect baseline data on the regularly used antibiotics in poultry production and to provide a greater understanding of the potential impact of antimicrobial resistance on public health.
