title: pH6 antigen (PsaA protein) of Yersinia pestis, a novel bacterial Fc-receptor.
abstract: It was found that recombinant pH6 antigen (rPsaA protein) forming virulence-associated fimbriae on the surface of Yersinia pestis at pH 6.7 in host macrophage phagolysosomes or extracellularly in abscesses such as buboes, is a novel bacterial Fc-receptor. rPsaA protein displays reactivity with human IgG1, IgG2 and IgG3 subclasses but does not react with rabbit, mouse and sheep IgG.
