Abstract

Opsonization of two different streptococcal group A type 12 strains was investigated. The strains differed only in M protein presence. It was observed that after the treatment of bacteria with fresh normal rabbit serum M positive strains bind to their surface IgG only whereas M negative strains solely some complement components. These results may suggest that streptococci lacking M protein are able to activate complement by alternate pathway.

研究了两种不同的A组12型链球菌的调理作用。不同的菌株只有M蛋白的存在。结果表明，经新鲜正常兔血清处理后，M阳性菌株仅与表面IgG结合，而M阴性菌株仅与部分补体成分结合。这些结果可能提示缺乏M蛋白的链球菌能够通过替代途径激活补体。
