Antigenic characterisitcs of Moraxella nonliquefaciens fimbriae in double immunodiffusion.
Rabbit antisera against purified fimbriae (pili) from Moraxella nonliquefaciens detected three fimbrial antigenic components, one or two of which appeared to be present in other fimbriated strains of M. nonliquefaciens and the closely related M. bovis. Maximal precipitation with the antisera required some denaturation of the antigen. Ultrasonication, repeated freeze-thawing, heating, and agents like KBr, NaSCN and urea were effective in liberating the antigen in diffusible forms. The morphology of the fimbriae was altered by heat treatment in 1 M KBr.
