Campylobacter is a major foodborne pathogen responsible for acute gastroenteritis characterized by diarrhea that is sometimes bloody, fever, cramps, and vomiting. Campylobacter species are carried in the intestinal tracts of mammals and birds, and sources of human infection include raw milk, contaminated water, direct contact with pets, and foods, particularly poultry. Campylobacter jejuni and C. coli are the species that account for the majority of human infections. The aim of this work was to determine the prevalence of Campylobacter in 190 poultry carcasses sampled at slaughter and to use a multiplex PCR assay to determine if the isolates were C. jejuni or C. coli. C. coli was not isolated, while C. jejuni was recovered from 52 (37.1%) of 140 carcasses for which pools of four sampling sites (neck, cloaca, breast, and back) were examined. In the remaining 50 carcasses, the four sites were analyzed separately, and C. jejuni was recovered from the samples in the following order: neck (n = 20), cloaca (n = 16), breast (n = 14), and back (n = 11). The results are in agreement with those of other studies, which showed that C. jejuni is more commonly associated with poultry than is C. coli. Control strategies for Campylobacter should include interventions to eliminate C. jejuni in poultry at various stages of production and processing, including at slaughter.
弯曲杆菌是一种主要的食源性病原体,可导致以腹泻(有时带血)、发热、痉挛和呕吐为特征的急性肠胃炎。弯曲杆菌存在于哺乳动物和鸟类的肠道中,人类感染源包括生牛奶、受污染的水、与宠物的直接接触以及食物,尤其是家禽。空肠弯曲杆菌和结肠弯曲杆菌是导致大多数人类感染的菌种。这项工作的目的是确定在屠宰时采集的190份家禽 carcasses 样本中弯曲杆菌的流行情况,并使用多重聚合酶链反应(PCR)检测来确定分离株是空肠弯曲杆菌还是结肠弯曲杆菌。未分离出结肠弯曲杆菌,而在对140份 carcasses 的四个采样部位(颈部、泄殖腔、胸部和背部)的样本池进行检测时,从52份(37.1%)中检出了空肠弯曲杆菌。在其余50份 carcasses 中,对四个部位分别进行分析,空肠弯曲杆菌按以下顺序从样本中检出:颈部(n = 20)、泄殖腔(n = 16)、胸部(n = 14)和背部(n = 11)。这些结果与其他研究结果一致,表明空肠弯曲杆菌比结肠弯曲杆菌更常与家禽相关。弯曲杆菌的控制策略应包括在生产和加工的各个阶段(包括屠宰时)采取干预措施以消除家禽中的空肠弯曲杆菌。
