The species usually causes infection between humans and livestock interaction via livestock breeding. The studies of the species thus far in all clinical isolates were to show the many kinds of antibiotic phenomenon that were produced. Their integrons cause the induction of antibiotic resistance between bacterial species in the species.
The bacterial strains from the diarrhea of pediatric patient which isolated by China Medical University Hospital storage bank. These isolates were identified by MALDI-TOF mass spectrometry. The anti-microbial susceptibility test showed that Campylobacter species resistant to cefepime, streptomycin, tobramycin and trimethoprim/sulfamethoxazole (all and isolates), ampicillin (89% of ; 75% of ), cefotaxime (78% of ; 100% of ), nalidixic acid (78% of ; 100% of ), tetracycline (89% of ; 25% ), ciprofloxacin (67% of ; 50% ), kanamycin (33% of ; 75% ) and the isolate resisted to ampicillin, cefotaxime, nalidixic acid, tetracycline, ciprofloxacin, kanamycin by disc-diffusion method. The effect for ciprofloxacin and tetracycline of the species was tested using an E-test. The , and genes were detected by PCR assay. According to the sequencing analysis (type I: -- genes and type II: gene), the cassette type was identified. The most common gene cassette type (type I: 9 and 2 isolates; type II: 1 isolates) was found in 12 class I integrase-positive isolates.
Our results suggested an important information in the latency of species with resistance genes, and irrational antimicrobial use should be concerned.
该物种通常通过家畜养殖在人与家畜的互动中引发感染。迄今为止,对该物种所有临床分离株的研究表明其产生了多种抗生素现象。其整合子导致该物种内细菌间抗生素耐药性的诱导。
从中国医科大学医院储存库分离出的小儿腹泻患者的细菌菌株。这些分离株通过基质辅助激光解吸电离飞行时间质谱法进行鉴定。抗菌药敏试验表明,弯曲杆菌属对头孢吡肟、链霉素、妥布霉素和甲氧苄啶/磺胺甲恶唑(所有 和 分离株)、氨苄西林( 的89%; 的75%)、头孢噻肟( 的78%; 的100%)、萘啶酸( 的78%; 的100%)、四环素( 的89%;25% )、环丙沙星( 的67%; 的50%)、卡那霉素( 的33%; 的75%)耐药,且 分离株通过纸片扩散法对氨苄西林、头孢噻肟、萘啶酸、四环素、环丙沙星、卡那霉素耐药。使用E-test检测该物种对环丙沙星和四环素的效果。通过PCR检测 、 和 基因。根据测序分析(I型: -- 基因和II型: 基因)鉴定盒式类型。在12株I类整合酶阳性分离株中发现最常见的基因盒式类型(I型:9 和2 分离株;II型:1 分离株)。
我们的结果提示了该物种耐药基因潜伏性的重要信息,应关注抗菌药物的不合理使用。
