Abstract
Poultry origin Campylobacter is considered as one of the leading causal agents of human foodborne illness. This study was conducted to estimate the occurrence, molecular identification, and antimicrobial resistance (AMR) of Campylobacter species from the broiler farms in Bangladesh. Samples (352) were collected from 32 farms and comprised of 128 cloacal swab, 64 feed, 64 drinking water, 64 attendants’ hand rinsed water, and 32 whole carcasses. All samples were tested for the presence of Campylobacter via cultural, biochemical, and PCR. The AMR was determined via the disc diffusion method. An overall occurrence of Campylobacter spp. was estimated as 26.4%. The level of Campylobacter contamination was found to be higher in conventional farms (36.4%) than the good practice farms (16.5%) including all sample categories (p = 0.000). Of 93 isolates, 67.74% and 32.26% were confirmed as C. jejuni and C. coli respectively, of which 34.92% C. jejuni, and 30% C. coli were shown to be multidrug-resistant. A significant occurrence of Campylobacter contamination in broiler farms with multidrug resistant patterns might be cogitated as serious food safety and public health concern linking to poultry food chain. A risk reduction approach through good farming practices targeting the prudent use of antimicrobials for broiler production is thus necessitated.
Highlights
Campylobacter spp. are food-borne pathogens which are microaerophilic, spiral, or slightly curved, motile, non-spore forming Gram-negative bacteria having a single flagellum at one or both poles [1]
A total of 246,307 human cases were confirmed as Campylobacter infection by the European Food Safety Authority (EFSA) as the highest occurrence for any bacterial pathogen in Europe, of which C. jejuni and C. coli were accountable as 83.6% and 8.5% respectively [5]
The survey confirmed an overall occurrence of Campylobacter spp. as 26.4% (93/352) through culture-based methods and biochemical tests
Summary
Campylobacter spp. are food-borne pathogens which are microaerophilic, spiral, or slightly curved, motile, non-spore forming Gram-negative bacteria having a single flagellum at one or both poles [1]. The thermophilic Campylobacter is well documented in poultry mostly in broilers and turkeys [2]. This organism is infrequently identified in commercial broiler flocks under the age of 2–3 weeks [3]. Campylobacter is recognized as one of the leading causal agents of foodborne gastroenteritis in humans. A total of 246,307 human cases were confirmed as Campylobacter infection by the European Food Safety Authority (EFSA) as the highest occurrence for any bacterial pathogen in Europe, of which C. jejuni and C. coli were accountable as 83.6% and 8.5% respectively [5]
