Infections with species have gained recognition as the most frequent cause of foodborne gastroenteritis globally. Their significance in South Africa is still an area of study interest. This study was, therefore, carried out to determine the occurrence of species in chickens from North West Province of South Africa as well as their antibiotic sensitivity status.
A total of 2400 chicken fecal samples were collected and pooled to a total of 480 samples from five registered active poultry abattoirs in the Ngaka Modiri Molema District of North West Province, South Africa. Polymerase chain reaction (PCR) was used for the detection of spp. targeting the gene while antibiotic sensitivity was determined using disk diffusion inhibition test.
After isolation, a total of 26 samples were confirmed to be harboring by PCR and sequencing. was found to be the only isolate detected in all the fecal samples tested. The study further demonstrated that infections were highest in the summer season (3%) followed by autumn and winter at 1%, while there were none detected in the spring. The isolated -positive samples on disk diffusion inhibition test displayed resistance to nalidixic acid, tetracycline, erythromycin, and ciprofloxacin at 98%, 80%, 83%, and 21%, respectively.
isolated in this study is known to cause disease in humans, and thus its occurrence requires application of "One Health" strategy to reduce the spread of this zoonotic pathogen in South Africa.
感染该物种已被公认为全球食源性肠胃炎最常见的病因。其在南非的重要性仍是一个研究热点领域。因此,本研究旨在确定南非西北省鸡群中该物种的出现情况及其抗生素敏感性状况。
从南非西北省恩加卡·莫迪里·莫莱马区的五个注册活跃家禽屠宰场收集了总共2400份鸡粪便样本,并合并为总共480个样本。采用聚合酶链反应(PCR)检测该物种,靶向该基因,同时使用纸片扩散抑制试验测定抗生素敏感性。
分离后,通过PCR和测序共确认26个样本携带该物种。该物种是在所检测的所有粪便样本中唯一检测到的分离株。研究进一步表明,该物种感染在夏季最高(3%),其次是秋季和冬季,均为1%,而春季未检测到。在纸片扩散抑制试验中,分离出的该物种阳性样本对萘啶酸、四环素、红霉素和环丙沙星的耐药率分别为98%、80%、83%和21%。
本研究中分离出的该物种已知可导致人类疾病,因此其出现需要应用“同一健康”策略来减少这种人畜共患病原体在南非的传播。
