Antigenic variation in Klebsiella.
The serological reactions of klebsiella strains repeatedly isolated from four patients were examined. Variations in capsular antigens of strains from the same patient were mainly restricted to slight changes in the titre of quellung reactions and occasionally differences in cross-reactions were noted. In one case a strain reacted more strongly with a heterologous antiserum than with homologous antiserum after it had been resident in the bowel of a patient for five weeks. No significant antigenic variation was observed when multiple colonies from the same klebsiella culture were tested.
