| Abstract: | Seasonal outbreaks of airsacculitis in China's poultry cause great economic losses annually.This study tried to unveil the potential role of Avian metapneumovirus(AMPV),Ornithobacterium rhinotracheale(ORT) and Chlamydia psittaci(CPS) in avian airsacculitis.A serological investigation of 673 breeder chickens and a case-controlled study of 430 birds were undertaken.Results showed that infection with AMPV,ORT,and CPS was highly associated with the disease.The correlation between AMPV and CPS were positively robust in both layers and broilers.Finally,we determined the co-infection with AMPV,ORT,and CPS was prevalent in the sampled poultry farms suffering from respiratory diseases and the outbreak of airsacculitis was closely related to simultaneous exposure to all three agents. |
