antimicrobial resistant pattern, plasmid profile and the survival ofisolated from poultry sources.

Abstract

1. Infections due tospp. significantly contribute to bacterial gastroenteritis worldwide. This study aimed to investigate whetherspp. can persist in poultry environments and how they survive in various sources from poultry farms and slaughterhouses.2. A total of 192 samples were collected from three different poultry farms and slaughterhouses andwas detected in 47.4% of them. The prevalence ofwas higher in poultry slaughterhouses than in farms. A total of 69were tested for their susceptibility to different antibiotics. From these 15 isolates from poultry farms and slaughterhouses, 50-70% exhibited antibiotic resistance. These isolates were analysed for plasmid profiling, identification of virulence genes and lipo-oligosaccharide characterisation.3. Nearly allisolates harboured plasmid sizes ranging from 2.3 to 23 kb. The virB11 gene ofwas characterised using PCR and there was no gene amplification in the isolated strains. All multidrug-resistant (MDR) isolates from poultry farms and slaughterhouses had full-length lipo-oligosaccharide molecules, based on their molecular weight.4. The MDR strain(LCJ5) was chosen for its survival rate from various sources, including lamb, chicken meat and eggs, as well as in the slaughterhouse environment, which contains materials like stainless steel, iron and wood. The findings suggested that the prevalence ofcan be reduced through improved hygiene practices and by raising awareness about the importance of consuming properly cooked meat products.
