摘要

摘要：大肠杆菌是监测抗微生物耐药性（AMR）的模式细菌。在本研究中，从鲤鱼养殖环境中筛选了232株大肠杆菌对12种抗生素的AMR。对头孢氨苄、阿莫、阿奇霉素、呋喃妥因、庆大霉素和土霉素的耐药性最高。98.70%的菌株存在多重抗生素耐药性，共有49个耐药谱。24株菌株血清型分为12个O-群（n = 21），粗糙型（n = 1），和不可类型化的（n = 2）。检测了泌尿系、肠系、肠毒素和肠出血性大肠杆菌的病理类型。高风险来源的肠道致病菌和MAR粪便细菌对养殖鲤鱼的污染令人担忧。

Enteric Pathogenic and Multiple Antibiotic-Resistant Escherichia coli in Farmed Indian Major Carps and Their Environments in Peri-Urban Kolkata, India

ABSTRACT Escherichia coli is targeted as a model bacterium for monitoring antimicrobial resistance (AMR). In this study, 232 E. coli strains from carp aquaculture environments were screened for AMR against 12 antibiotics. Maximum resistance was found against cefalexin, amoxyclav, azithromycin, nitrofurantoin, gentamycin, and oxytetracycline. Multiple antibiotic-resistance was noted in 98.70% of the strains with 49 resistant profiles. Twenty-four strains were serotyped into 12 O-groups (n = 21), rough type (n = 1), and untypeable (n = 2). Uropathogenic, enteropathogenic, enterotoxigenic, and enterohemorrhagic E. coli pathotypes were detected. The contamination of aquacultured carps with enteric pathogenic and MAR fecal bacteria from high-risk sources is a cause for concern.

期刊介绍： The Journal of Aquatic Food Product Technology publishes research papers, short communications, and review articles concerning the application of science and technology and biotechnology to all aspects of research, innovation, production, and distribution of food products originating from the marine and freshwater bodies of the world. The journal features articles on various aspects of basic and applied science in topics related to: -harvesting and handling practices- processing with traditional and new technologies- refrigeration and freezing- packaging and storage- safety and traceability- byproduct utilization- consumer attitudes toward aquatic food. The Journal also covers basic studies of aquatic products as related to food chemistry, microbiology, and engineering, such as all flora and fauna from aquatic environs, including seaweeds and underutilized species used directly for human consumption or alternative uses. Special features in the journal include guest editorials by specialists in their fields and book reviews covering a wide range of topics.
