74 个国家的大约 2 亿感染血吸虫的人都承认他们接触过含有受感染蜗牛的淡水。该研究的目的是表征来自巴西伯南布哥州的野生和实验室饲养的光滑生物脐蜗牛的微生物群。这些软体动物的微生物群通过 VITEK 2 自动化微生物系统进行生化鉴定。采用纸片扩散法对β-内酰胺类抗生素、氨基糖苷类、喹诺酮类、叶酸途径抑制剂、苯尼考类和四环素类药物进行药敏试验。结果显示，所有细菌均为革兰氏阴性，包括11个细菌属：气单胞菌属、柠檬酸杆菌属、肠杆菌属、铜杆菌属、根瘤菌属、寡养单胞菌属、假单胞菌属、克雷伯菌属、不动杆菌属、弧菌属和鞘氨醇单胞菌属。关于抗菌药物敏感性，所有分离株均表现出对阿莫西林的耐药性和对美罗培南（β-内酰胺类抗菌药物）的敏感性。野生蜗牛的微生物群主要由阴沟肠杆菌组成，而实验室饲养的蜗牛主要由弗氏柠檬酸杆菌和温和气单胞菌组成。
Roughly 200 000 000 people in 74 countries infected with schistosomes all share the fact that they came in contact freshwater harbouring infected snails. The aim of the study is to characterize the microbiota of wild and laboratory‐reared snails of Biomphalaria glabrata from Pernambuco, Brazil. The microbiota of these molluscs was identified biochemically by the VITEK 2 automated microbiological system. Antimicrobial susceptibility testing was carried out by the disc diffusion method with ß‐lactam antibiotics, aminoglycosides, quinolones, folate pathway inhibitors, fenicols and tetracyclines. The results showed that all bacteria identified were gram‐negative, including 11 bacterial genera: Aeromonas, Citrobacter, Enterobacter, Cupriavidus, Rhizobium, Stenotrophomonas, Pseudomonas, Klebsiella, Acinetobacter, Vibrio and Sphingomonas. Regarding the antimicrobial susceptibility, all the isolates exhibited resistance to amoxicillin and sensitivity to meropenem (beta‐lactam antimicrobials). The microbiota of the wild snails consisted predominantly of Enterobacter cloacae, while the laboratory‐reared snails predominantly showed Citrobacter freundii and Aeromonas sobria.
