Serological Survey of the Avain Leukosis Virus Infection in China Native Chickens

摘要

To investigate the Avain leukosis virus infection status in China native chicken flocks, 2530 serum samples from 26 kinds of China native chickens were collected and detected using the Avian Leukosis Virus Antibody Test kit (ALV-A/B) and Avian Leukosis Virus Antibody Test kit-Subgroup J (ALV-J). The results showed that among 2530 sera samples 118 samples were positive for ALV-A/B, 332 samples were positive for ALV-J and 35 samples were positive for both ALV-A/B and ALV-J. The positive rate for ALV-A/B, ALV-J and their co-infection was 0-16.67, 0-59.60 and 0-5.05%, respectively. This investigation suggests that the infection of ALV-A/B, ALV-J and their co-infection do exist or even very popular in some native chickens flocks in China and the prevention of ALV should be given more attention.
