SUMMARY: In S-1, D-galactosamine and L-rhamnose comprised a phage receptor for phage J-1. A mixture of D-galactosamine and L-rhamnose effectively inactivated phage J-1, and a J-1-resistant mutant strain, S-1/J-1, lacked D-galactosamine in its surface component. The phage-inactivating effects of D-galactosamine and L-rhamnose were strongly dependent on the concentration of each substance and on temperature.

SUMMARY: It is suggested that the receptor for phage J-1 involves both D-galactosamine in the cytoplasmic membrane and L-rhamnose in the wall of the host bacterium S-1, which lacks teichoic acid in its wall.
