Abstract
E. coli donor strains having antigen K1(L) or K4(L) transfer them to recipient cells at a genetic locus (kps A) similar to that of K10(L) and K54(L) linked to ser A. In crosses between the K10 donor strain and recipient strains 08:K8(L), 08:K27(A) and 09:K57(B) all recombinants which inherit donor K antigen also inherit K antigen of recipient. The non-allelism between donor and recipient K antigens is indicated, and the structures of all polysaccharide K antigens of strains having O antigens O8 or O9, whether termed L, A or B, are probably controlled by genes which differ in their location on the chromosome from genes controlling polysaccharide K antigens associated with most other O antigens.
