[Anodically moving thermolabile antigen (ATA) of Gram-negative bacteria. Its antibody-forming capacity in rabbits and mice].

Injection of purified ATA as well as of ATA-containing crude sonic extracts of gram-negative bacteria into rabbits or mice causes rapid occurrence of anti-ATA antibodies. Thus, the retarded occurrence of anti-ATA antibodies after immunization with living bacteria can be explained by the rather deep localization of ATA in the cell wall.
