82 Dichelobacter nodosus strains isolated from 9 footrot affected sheep flocks in south west Germany were serotyped and tested for virulence. Serovar B was present in all flocks, representing 64.4% of all isolated D. nodosus field strains. Other serovares found were type A, C, E, G and H. Virulent strains were identified in 5 flocks, while intermediate strains were isolated from all 9 flocks. All serological untypeable strains proved to be avirulent. Based on these epidemiological findings the use of currently available commercial footrot vaccines is appropriate in south west German sheep populations.
对从德国西南部9个患腐蹄病的绵羊群中分离出的82株结节拟杆菌进行了血清分型和毒力测试。所有羊群中均存在血清型B,占所有分离出的结节拟杆菌田间菌株的64.4%。发现的其他血清型有A、C、E、G和H。在5个羊群中鉴定出了强毒株,而从所有9个羊群中均分离出了中间型菌株。所有血清学无法分型的菌株均被证明无毒力。基于这些流行病学调查结果,目前可用的商业腐蹄病疫苗适用于德国西南部的绵羊群体。
