Avian pneumovirus (APV) causes upper respiratory tract infection in chickens and turkeys. There is a serious respiratory disease in chickens, resulting in catastrophic economic losses to chicken farmers in Jordan. The objective of this study was to investigate the role of APV as a factor in the respiratory disease of chickens in Jordan by serological and molecular methods. Thirty-eight chicken flocks were examined by competitive ELISA (23 broilers, 8 layers, and 7 broiler breeders), and 150 chicken flocks were examined by reverse-transcription PCR (133 broiler flocks, 7 layer flocks, and 10 broiler breeder flocks). Avian pneumovirus antibodies were detected in 5 out of 23 broiler flocks (21.7%), 6 out of 8 layer flocks (75%), and 7 out of 7 broiler breeder flocks (100%). Avian pneumovirus nucleic acid was detected in 17 broiler flocks (12.8%) and 3 layer flocks (42.9%). None of the broiler breeder flocks tested by reverse-transcription PCR was positive. All of the 20 detected APV isolates were subtype B. This is the first report of APV infection in Jordan. In conclusion, the Jordanian poultry industry, vaccination programs should be adjusted to include the APV vaccine to aid in the control of this respiratory disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
