Abstract：
Campylobacter is one of the most common causes of foodborne gastroenteritis. The objective of this study was to estimate the prevalence and risk factors associated with Campylobacter jejuni and Campylobacter coli species in fresh chicken carcasses for human consumption from farmers\' markets and small food stores in seven localities of Bogotá, Colombia. Ninety-one samples of fresh chicken carcasses were collected from farmers\' markets and small food stores at seven localities in Bogotá. Samples were tested for Campylobacter using the real-time polymerase chain reaction (real time PCR) and isolation by plating. To analyze possible risk factors associated with Campylobacter spp. contamination in retail chicken carcasses, information was collected using a structured questionnaire and a univariate logistic regression analysis (α = 0.05) was used. Forty-two positive samples were obtained for Campylobacter spp., given a prevalence of 46.2%, of which 54.8% were to C. jejuni, 9.52% to C. coli and 35.7% to joint contaminations. C. jejuni was the most prevalent species. Risk factors found included poor cleanliness, in frequency of disinfection, type of establishment, and direct contact of chickens with other food. This study is the first report in the country on the prevalence and risk factors of Campylobacter in retail chicken.
摘要：
弯曲杆菌是食源性胃肠炎的最常见原因之一。这项研究的目的是估计与空肠弯曲杆菌和弯曲杆菌相关的流行率和危险因素在新鲜的鸡尸体供人类消费从农贸市场和小食品商店在波哥大的七个地方,哥伦比亚。从波哥大七个地方的农贸市场和小型食品商店收集了91个新鲜鸡肉尸体样本。使用实时聚合酶链反应(实时PCR)并通过铺板分离来测试样品的弯曲杆菌。分析与弯曲杆菌相关的可能危险因素。零售鸡肉尸体的污染，使用结构化问卷收集信息,并使用单因素logistic回归分析(α=0.05).获得了42个弯曲杆菌属阳性样品。,鉴于患病率为46.2%，其中54.8%是空肠杆菌，9.52%的大肠杆菌和35.7%的联合污染。空肠杆菌是最普遍的物种。发现的危险因素包括清洁度差，在消毒频率上，类型的建立，鸡与其他食物直接接触。本研究是国内首例关于零售鸡肉中弯曲杆菌的流行和危险因素的报告。
