A serological investigation of Legionella infection in six-species of poultries and domestic animals in Luzhou city, Sichuan Province

目的 了解泸州市家禽家畜中军团菌感染状况及其主要型别。方法 采用微量凝集试验(MAT)对该市鸡、鸭、鹅、牛、猪、兔6种家禽家畜进行了嗜肺军团菌(Lp1～14型)和米克达德军团菌(Lm)的血清学调查。结果 结果显示,家禽家畜中呈多型性感染特征,并有其各自的优势菌型;各型别抗体阳性率分别为2.00%～28.75%;家畜合计阳性率为4.49%,家禽合计阳性率为6.47%。结论 说明当地家禽家畜中存在广泛的军团菌感染,提示对动物和外环境进行军团菌病的流行病学监测,对于防治人群患军团菌病具有一定意义。

Objective To understand the prevalence rates of Legionella infection in poutries and domestic animals in Luzhou city. Methods Serological investigation of antibodies against Legionella pneumophila serogroups 1-14 and Legionella micdadei was carried out, using microagglutination test (MAT) in six species of poutries and domestic animals. Results Results showed that the infection with multiple serogroups was present. However,each species had its own serogroup with positive rates of different serogroups ranging from 2.00% to 28.75%. Positive rates of domestic animals and poultry accounted for 4.49% and 6.47% respectively. Conclusion It was suggested that poultries and domestic animals were widely infected with Legionella .
