引言

牛副流感病毒3型（Bovineparainfluenzavirustype3，BPIV3）和山羊副流感病毒3型（Caprine

parainfluenzavirustype3，CPIV3）同屬于副黏病毒科（Paramyxoviridae）副黏病毒亞科（Paramyx?

ovirinae）呼吸道病毒屬（Respirovirus），兩者核苷酸同源性接近81%，血清學有交叉反應。2022

年，國際病毒分類委員會（InternationalCommitteeonTaxonomyofViruses，ICTV）將BPIV3和

CPIV3分別重新命名為牛呼吸道病毒3型（BovineRespirovirus3）和山羊呼吸道病毒3型（Caprine

Respirovirus3），考慮到我國相關標準的延續(xù)性，為便于使用者查詢和應用，本文件仍采用原病毒命名

名稱。

BPIV3主要感染牛，也可能感染鹿、豬、羊等；CPIV3主要感染山羊和綿羊。易感動物感染病毒后

均以發(fā)熱、咳嗽、流鼻液為主要臨床癥狀，確診需進行實驗室診斷。本文件給出了BPIV3和CPIV3感

染的臨床診斷、病原學檢測（病毒分離鑒定、RT?PCR、Real?timeRT?PCR）、血清學檢測（cEL?

ISA和病毒中和試驗）的操作規(guī)范。在對牛源樣品進行病原學檢測時，推薦采用RT?PCR或Real?time

RT?PCR方法檢測BPIV3；對羊源樣品進行病原學檢測時，推薦采用RT?PCR或Real?timeRT?PCR方

法同時檢測CPIV3和BPIV3。兩種病毒在血清學有交叉反應，因此，本文件中的血清學方法能同時檢

測CPIV3和BPIV3感染的抗體。
