A Study of Antigenic Relativity on Muscovy Duck Parvovirus and Goose Parvovirus
-
摘要: 应用微量交叉中和试验 (NT) 和胶乳凝集抑制试验 (LPAI) 比较番鸭细小病毒、鹅细小病毒和番鸭源鹅细小病毒之间的抗原相关性。结果显示:3种病毒与同源抗血清的中和效价和LPAI效价均明显高于异源血清;番鸭细小病毒与番鸭源鹅细小病毒、鹅细小病毒之间的R值均小于0.1;番鸭源鹅细小病毒与鹅细小病毒的R值大于0.25。结果表明番鸭细小病毒与鹅细小病毒 (番鸭源或鹅源) 的抗原相关性较低, 提示番鸭源鹅细小病毒与鹅细小病毒属于同一血清型的不同亚型。Abstract: Antigenic relationship of Muscovy duck parvovirus (MPV F strain) , Muscovy duck origin goose parvovirus (MDGPV PT strain) and Goose parvovirus (GPV GD strain) were determined by virus crossneutralization tests (NT) and latex agglutination inhibition test (LPAI) .The results showed that neutralization titer and LPAI titers of homologous antiserum were significantly higher than heterologous serum;R values of MPV compared with MDGPV and GPV were less than 0.1.R value between MDGPV and GPV was greater than 0.25.The results showed that MPV has low antigenic correlation with GPV and MDGPV, which indicated that antigenic variations are obviously existed between MPV and the other two, and showed that GPV and MDGPV belong to different subtypes of the same serotype.
