Salmonella serotypes isolated from Frozen chicken meat from Al- Najaf province markets

Abstract

Salmonella is a zoonotic pathogen that can transfer from animals, contaminated animal products and contaminated water to humans. Non-Typhoidal Salmonella (NTS) are widely spread in wild, domestic animals and human being because it has no host restriction and this presents a broad spectrum of challenges to the public health causing gastroenteritis infections and dissemination of antibiotic resistance. Poultry is one of the most well-known host of NTS without apparent clinical manifestation, but study on overall salmonella population structure is limited. Therefore, a population structure study of salmonella serotypes in chicken meat is important to identify Salmonella serotypes and antibiotic resistance profile in Al-Najaf province. We targeted a novel genomic region that was previously approved for its ability to detect salmonella serotypes, strains of Salmonella in frozen chicken flesh, and antibiotic resistance patterns were conducted. 160 specimens from frozen chicken meat during the period extended from October 2020 to December 2020, 30 livers, 49 complete chickens, 25 thighs, and 56 breasts, collected from Al-Najaf province markets 44 (100%). The isolated samples were dominated by S. Infantis, 39/44 (88%) and 1/44 (2.2%) S.Enteritidis. Two non-salmonella bacteria, Citrobacter freundii 2/44 (4.5%) and Enterobacter cloacae 2/44 (4.5%) however.
