上杭县人畜李斯特氏菌病发病与带菌调查研究

A Study on the prevalence and infection rate of Listeriosis in Shanghang, Fujian

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１６６０％，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 invastigate the epidemiological characteristics and the rules of Listeriosis in Shanghang county and take countermeasure for the disease control. METHODS To carry out a field epidemiological survey and etiological study on Listeriosis. RESULTS 161 strains of Listeria, among which the pathogenic type accounted for 69.0%, were isolated from 970 specimens. The total isolation rate was 16.60%. There is close relationship between Listeria carrying rate and prevalence. The first morbidity peak emerged form May to June and the second form November to December. CONCLUSIONS The Listeriosis epidemic is mainly in livestock and no ideal control method is available at present. The new type of Listeria must be further studied, which can produce H 2S and result in a lot of death for the pigs and cattle.
