目的:摸清上杭县畜间李斯特氏菌病发病特点和流行规律,提出防治对策和建议。方法:定点进行了流行病学调查和病原学研究。结果:共检测各类标本970份,分离出161株李斯特氏菌,总检出率为1660%,其中致病菌型占69%,带菌率高低与本病流行有密切关系。其流行特点:流行5~6月份出现第1高峰,11~12月份出现第2高峰。结论:本病目前主要在畜间流行,目前尚缺理想的防制方法。产H2S型李斯特氏菌为新型菌,可致猪、牛发生死亡,应加强对该菌的进一步研究。
Objective: To find out the characteristics and prevalence of listeriosis in Shanghang County and to put forward the countermeasures and suggestions for prevention and control. Methods: Epidemiological investigation and etiological research were carried out. Results: A total of 970 specimens were detected, 161 strains of Listeria were isolated, the total detection rate was 16.6%, of which pathogenic bacteria accounted for 69%. The prevalence of infection was closely related to the epidemic of this disease. Its popular features: the first peak appeared from May to June, the second peak from November to December. Conclusion: The current prevalence of this disease mainly in domestic animals, the current lack of ideal control methods. Listeria H2S-producing bacteria as a new type, can cause pigs, cattle died, should be strengthened further study of the bacteria.
