title: Serological cross-reactivity between group B Streptococcus and Sporothrix schenckii, Ceratocystis species, and Graphium species.
abstract: Serological cross-reactivity of a group B Streptococcus (H36B) with Sporothrix schenckii and 39 different Ceratocystis and Graphium species was investigated by double immunodiffusion. Rabbit anti-H36B serum reacted with antigens from S. schenckii and from 36 of 39 Ceratocystis and Graphium species. It is speculated that low-titer agglutinins to S. schenckii in normal sera are due to antibodies raised against various bacteria which share common antigens with S. schenckii.
