Human and animal serotypes of Bacteroides gingivalis defined by crossed immunoelectrophoresis.

摘要: The antigenic complexity of three strains Bacteroides gingivalis and four resembling B. isolated from animals was analyzed compared by crossed immunoelectrophoresis. Thirteen antigens the human biotype were present in all six animal strains, indicating a marked serological homogeneity within each biotype. Four cross-reacting between identified. This relatedness defined two biotypes species allowed recognition species-specific antigens. Two specific to identified, that serotype-specific can distinguish It is thus proposed oral, black-pigmented asaccharolytic origin be classified as catalase-positive variants gingivalis. also serotypes recognized Serotype 1 includes catalase-negative biotype, serotype 2
