By using hot acid extract and double-diffusion studies, an antigen isolated from clinical strains of Moraxella catarrhalis, designated the C antigen, was studied. The antigen is labile, relatively trypsin insensitive, and either polysaccharide or glycoconjugate in nature. At least two serologically distinct C antigens have been identified.
