Isolates of capripoxvirus collected from sub-Saharan Africa were compared in sheep, goats and cattle and by restriction endonuclease digestion of their purified DNA. Biochemical techniques were used to precisely identify strains of capripoxvirus for epidemiological investigations. Strains of capripoxvirus infecting cattle have remained very stable over a 30-year period and are closely related to strains recovered from sheep in Africa.
对从撒哈拉以南非洲收集的山羊痘病毒分离株在绵羊、山羊和牛身上进行了比较,并通过对其纯化DNA进行限制性内切酶消化来比较。采用生化技术精确鉴定山羊痘病毒株,用于流行病学调查。感染牛的山羊痘病毒株在30年期间一直非常稳定,并且与从非洲绵羊身上分离出的毒株密切相关。
