摘　　要： 链球菌(Streptococcus spp.)是一种广泛分布于自然界的革兰氏阳性菌,是人类的重要病原之一,也是其他多种脊椎动物包括猪、牛、鱼等的重要病原菌。目前已有多个国家报道了鱼类链球菌病的暴发与流行,受感染的鱼类包括多种海水和淡水鱼类,以温水性鱼类最为严重。近年中国罗非鱼链球菌感染的报道也呈现增加趋势,尤其在2009年,广东、海南、福建和广西地区养殖罗非鱼的链球病发病率为20%～50%,死亡率达50%～70%,甚至更高。链球菌病已严重危害着中国罗非鱼养殖业的健康发展。文章对罗非鱼链球菌病的病原、流行及防治方法作一综述,以期为今后开展罗非鱼链球菌病防控研究提供参考。 Streptococcus spp. is gram-positive and one of the major bacterial pathogens causing infectious diseases in human as well as in many vertebrates including swine, cattle and fish. Currently, the outbreak and prevalence of streptococcosis in fish, often occurring in various species of marine and freshwater fishes and mostly occurring in fishes of warm waters, have already been reported by many countries. There are more and more reports of tilapia infected with streptococcosis in China. In 2009, the outbreaks of streptococcosis were found in tilapia farms in southern China, including Guangdong, Guangxi, Fujian and Hainan provinces; the rates of streptococcal infectivity and mortality were 20% - 50% and 50% - 70%, respectively. Thus, streptococcosis has seriously hindered the development of tilapia aquaculture. This review summarized the reports on pathogeny, epidemiology, control and prevention of streptococcosis in tilapia, which would provide references for the prevention and control of streptococcosis in tilapia in the future.
