Abstract

Abstract

Objective In order to explore the current morbidity and epidemic trend of three kinds of common viral immunosuppressive diseases in chicken flocks in southeast Guangxi. Method From March 2018 to April 2019, a total of 637 sick chicken sera were collected from scattering chicken raising households in nine counties and cities including Yulin, Beiliu, Xingye, Bobai, Rongxian, Luchuan, Guigang, Guiping and Pingnan, to detect the serum antibodies against three viruses by an enzyme-linked immunosorbent assay (ELISA) and analyzed the impact of different factors including region, season, breed and age on the infection statuses of these three viral immunosuppressive diseases. Result The results showed that the antibodies against three common immunosuppressive viruses were ubiquitous in the above areas and the positive rates of antibodies against different viruses were affected by regions, seasons, breeds and age groups of the chicken flocks. The positive rates of antibodies against Chicken infectious anemia virus (CIAV), Reticuloendotheliosis virus (REV) and Avian reovirus (ARV) were 23.86%, 13.97% and 7.06% respectively, indicating that the positive rate of CIAV were higher than other two viral immunosuppressive diseases in chicken flocks of the farmers in the above-mentioned regions and it should be regarded as the focus of the prevention and control of epidemic diseases in chicken flocks. In addition, multi-infection was the common infection type, as the mixed infection rate reached up to 24.65%, and CIAV co-infection with other pathogens were the most common diversified infection type, accounting for 98.11%. Conclusion This study provided the serological surveillance of chicken viral immunosuppressive diseases in the chicken flocks of the scattering raising households in the region of southeast Guangxi and provided a reliable reference for making control measures of these three kinds of common viral immunosuppressive diseases.
