The Serology of Pseudomonas pyocyanea

Abstract

Three main antigens were found to be variously distributed among strains of P. pyocyanea. The serological behavior of the strains studied depended on the presence and quantity of these antigens. It was not possible to distinguish between flagellar and somatic antigens, those found were probably somatic. A striking peculiarity was a complete loss of agglutinability on moderate heating, which left the antigenic activity unimpaired.
