Non-typhoidal Salmonellosis, a zoonotic infection associated with acute gastroenteritis is caused by non-typhoidal salmonellae (NTS). The study was carried out to determine the prevalence of NTS serovars and their antimicrobial resistance along with the presence of the virulence gene ( gene) in poultry samples.
This is a prospective cross-sectional study carried out at the Enteric Diseases Division, Kasturba Medical College, Manipal, South India from January 2016- December 2017. Poultry samples were collected randomly from two local poultry farms in Udupi district and processed following CDC standard protocol.
From the 396 poultry meat samples, intestinal contents and faecal samples collected, 58 NTS serovars were isolated showing a prevalence of 14.64%. Infantis, 43.1%, 25/58 was the commonest serovar. Resistance to ciprofloxacin 72.41%, ampicillin 32.8%, gentamicin 17.24%, cotrimoxazole 29.31% and amoxicillin-clavulanic acid 6.9% was observed. The gene was detected in 43 NTS isolates (74.13%).
Poultry sources are recognized as a significant cause for non-typhoidal salmonellosis. Therefore, hygienic measures should be initiated to reduce the contamination of meat and poultry products with virulent strains of Salmonella that are of public health significance.
非伤寒沙门氏菌病是一种与人畜共患的急性肠胃炎相关的感染病，由非伤寒沙门氏菌（NTS）引起。本研究旨在确定家禽样本中NTS血清型的流行情况及其抗菌耐药性，以及毒力基因（基因）的存在情况。
这是一项前瞻性横断面研究，于2016年1月至2017年12月在印度南部马尼帕尔卡斯图尔巴医学院肠道疾病科开展。从乌度皮区的两个当地家禽养殖场随机采集家禽样本，并按照美国疾病控制与预防中心（CDC）的标准方案进行处理。
在所采集的396份家禽肉样本、肠道内容物和粪便样本中，分离出58株NTS血清型，流行率为14.64%。婴儿沙门氏菌血清型最为常见，占43.1%（25/58）。观察到对环丙沙星的耐药率为72.41%，氨苄西林为32.8%，庆大霉素为17.24%，复方新诺明为29.31%，阿莫西林-克拉维酸为6.9%。在43株NTS分离株（74.13%）中检测到该基因。
家禽源被认为是非伤寒沙门氏菌病的一个重要病因。因此，应采取卫生措施，以减少具有公共卫生意义的沙门氏菌强毒株对肉类和家禽产品的污染。
