山东省部分地区种鸭场呼肠孤病毒和细小病毒感染情况调查
Investigation of Reovirus and Parvovirus Infection in Duck Farms in Some Areas of Shandong Province
摘要
Abstract
To understand the prevalence of duck reovirus and parvovirus in Shandong Province,a total of 2,159 serum samples,960 cloacal swabs,and 750 terminated embryos samples were randomly selected from 20 large-scale duck breeding farms across Weifang,Tai'an,Liaocheng,Dongying,and Rushan,com-prising 2 ancestral breeding farms and 18 parental farms,during January 2022 and December 2024.En-zyme-linked immunosorbent assay(ELISA)was employed to detect antibodies against duck reovirus and duck parvovirus in serum samples,while fluorescent PCR was used to for the detection of duck reovirus and duck parvovirus in cloacal swabs and termination embryo.The results showed that the natural infec-tion rate of reovirus in the breeding duck population of Shandong Province was relatively high.Significant differences were observed in the positive rates of antibodies among parental breeding ducks across different sampling periods(P＜0.001).The natural infection rate of duck parvovirus was low.Both fluorescence PCR tests of cloacal cotton swabs and termination embryo for duck reovirus and parvovirus returned nega-tive results.Overall,the grandparent and parent duck populations in Shandong exhibited a widespread cov-ert infection status with duck reovirus,although the likelihood of vertical transmission appeared relatively low,with horizontal transmission being the predominant route.It is recommended that Shandong imple-ment enhanced management and biosafety measures for breeding ducks and continue epidemiological moni-toring of duck reovirus to establish a foundation for effective disease prevention and control.关键词
