Abstract
In order to investigate the status of reticuloendotheliosis virus(REV)and avian leukosis virus(ALV)prevalent in chicken breeding farms in Beijing,2 660 serum samples and 2 660 egg liquid samples collected from 27 farms across 9 districts in 2021 were respectively monitored for REV antibody and ALV p27 antigen using ELISA method.The results revealed that,for REV antibody and ALV p27 antigen,the apparent individual positive rates were 33.83%and 1.54%,respectively,with respective true positive rates of 34.53%(95%CI:32.72%-36.33%)and 1.57%(95%CI:1.10%-2.05%);and the apparent population positive rates were 81.48%and 29.63%,respectively,with respective true positive rates of 83.14%and 30.23%.The two kinds of pathogens were detected out in all quarters except the fourth one when no REV antibody was detected,specifically,the individual positive rate of ALV was highest(4.86%)in the third quarter,with a statistically significant difference from that in other quarters(P＜0.05),while the individual positive rate of REV was highest(85.40%)in the second quarter,with significant difference in different quarters(P＜0.05).Individuals positive for REV antibody and ALV p27 antigen were detected out from both grandparent and parental generations,and the difference in positive rates was statistically significant(P＜0.05).In conclusion,REV and ALV were seriously and widely prevalent in the farms in Beijing due to poor purification,posing a risk of pathogen transmission.All farms were thus recommended to give top priority to the prevention and control of the two diseases,and to push forward the purification for the chicken population.A basis was provided by the results of monitoring for future prevention,control and purification of REV and ALV infection in Beijing.关键词
