[A serological investigation of Legionella infection in eight-species of poultry and domestic animals in Sichuan province].

OBJECTIVE
To understand the prevalence rates of Legionella infection in poultries and domestic animals in Sichuan province.


METHODS
Serological investigation of antibodies against Legionella pneumophila serogroups 1 - 14 and Legionella micdadei was carried out, using microagglutination test (MAT) in eight species of poultries and domestic animals.


RESULTS
Infections with multiple serogroups were identified. However, each species had its own major serogroup with positive rates of different serogroups ranging from 0.83% to 59.18%. Positive rates of the poultry and domestic animals were accounted for 7.73% and 4.25% respectively.


CONCLUSION
It was suggested that poultries and domestic animals were widely infected with Legionella. It is important to carry out epidemiological surveillance in these domestic animals, poultries and environment for a better control program of this disease.
