摘 要: [目的]为罗非鱼食源致病微生物的预警和防治提供理论基础。[方法]对秋季广东省不同区域3个养殖场的正常罗非鱼体及其养殖环境中食源性致病菌种类进行调查分析。[结果]罗非鱼及其养殖环境受致病微生物不同程度的污染,分离到的致病菌经初步鉴定为10个菌属,其中以埃希菌属最多,鱼体检出率为67%,养殖环境检出率为100%;沙门氏菌属在罗非鱼体中的检出率(52%)比养殖环境中检出率(39%)高;其次为克雷伯氏菌属、假单胞菌属、链球菌属、变形杆菌、肠杆菌属、金色单胞菌属、伯克霍尔德氏菌属等。[结论]秋季罗非鱼体及养殖环境正受各种致病菌不同程度的污染。 [ Objective ] The study aimed to provid theoretical basis for warning and control of food-borne pathogenic microorganism in tilapia. [ Method] Investigation and diversity analysis of food-borne pathogenic microorganism in the normal tilapia and their cultivation environment in different parts of Guangdong Province' s fish farms were done. [ Result] The results showed that tilapia and their cultivation environment was being polluted in different degrees by pathogenic microorganisms. Pathogenic microorganism that was isolated belonged to 10 bacteria genus, Escherichia coli's detection rate was largest (67% in tilapia and 100% in culture environment); Salmonella's detection rate in tilapia (52%) was higher than in culture environment (39%); followed by KlebsieUa spp, Pseudo monas, Streptococcus, Proteus, Enterobacter, Chryseomonas, Burkholderia and so on. [ Conclusion ] Tilapia and their cultivation environment was being polluted in different degrees by pathogenic microorganisms in autumn.
