Abstract

India is the second largest fish producing nation after China, contributing about 5.68% of the global fish production. The state West Bengal is occupying the second position in freshwater fish production after Andhra Pradesh. Although a number of constraints have been put forth, diseases and poor farm management are some of the most noticeable reasons for the reduced fish production in West Bengal. This study reports the prevalence of diseases caused by Flavobacterium spp. and other opportunistic bacteria in carps of sewage-fed farms in West Bengal. The bacteriological examination of the diseased carps revealed infections with different bacterial species and most of them were opportunistic pathogens. Flavobacteriosis, aeromoniasis, pseudomoniasis and other mixed bacterial infections, as confirmed by conventional biochemical tests and by VITEK 2 Compact system, were noted frequently. Antibiotic sensitivity of the opportunistic bacterial pathogens from the diseased carps indicated that some of these bacterial strains are resistant to potential human medicines like erythromycin, cotrimoxazole, oxytetracycline, nitrofurantoin, etc., which is a serious cause for concern. These results further present the fact that sewage-fed fish farms and the food fish from such systems may pose a serious public health risk from the antibiotic-resistant bacteria, if not handled properly.
黄杆菌和其他机会性细菌在印度西孟加拉邦污水养殖农场的鲤鱼中引起的疾病流行
印度是仅次于中国的第二大鱼类生产国,占全球鱼类产量的5.68%。西孟加拉邦的淡水鱼产量仅次于安得拉邦。虽然提出了一些限制,但疾病和养殖场管理不善是西孟加拉邦鱼类产量减少的一些最明显的原因。本研究报告了由黄杆菌和其他机会性细菌引起的疾病在西孟加拉邦污水养殖农场的流行。病鱼的细菌学检查显示感染的细菌种类不同,以条件致病菌居多。黄杆菌病、气单胞菌病、假单胞菌病和其他混合细菌感染,经常规生化试验和VITEK 2 Compact系统证实,经常被注意到。从患病鲤鱼中分离出的条件致病菌对抗生素的敏感性表明,其中一些菌株对红霉素、复方新诺明、土霉素、呋喃妥英等潜在的人类药物具有耐药性,值得严重关注。这些结果进一步表明,如果处理不当,污水养鱼场和来自这些系统的食用鱼可能会因耐抗生素细菌而构成严重的公共卫生风险。
