Clinical cases of infectious bovine rhinotracheitis and infectious pustular vulvovaginitis were observed within the cattle population in Algeria. The isolation and identification of six bovine herpes virus type 1 strains from diseased cattle and the serological surveys undertaken in the central region of the country on 2948 sera revealed a 20.5% incidence of IBR infections in Algeria. The DNA restriction profiles of the isolated strains showed the existence of only the BHV1-2a subtype associated with the endemic infections in Algerian cattle. These results emphasized also the lack of correlation between the observed clinical symptoms and the DNA restriction pattern of the isolated herpes virus strain. The plans for disease control are based mainly on the application of strict control measures at the borders for avoiding the introduction of other BHV1 subtypes.
在阿尔及利亚的牛群中观察到了传染性牛鼻气管炎和传染性脓疱性外阴阴道炎的临床病例。从患病牛中分离并鉴定出6株牛疱疹病毒1型毒株，并且在该国中部地区对2948份血清进行的血清学调查显示，阿尔及利亚IBR感染的发病率为20.5%。分离毒株的DNA限制性图谱表明，在阿尔及利亚牛群的地方性感染中仅存在与BHV1-2a亚型相关的毒株。这些结果还强调了观察到的临床症状与分离出的疱疹病毒毒株的DNA限制性图谱之间缺乏相关性。疾病控制计划主要基于在边境实施严格的控制措施，以避免引入其他BHV1亚型。
