FIG. 9.

Effect of antibodies raised against partial peptides within the AtlA protein on chain length and autolytic activity. (A) Light microscopic views. Xc was grown in BHI broth including each purified antibody (final concentration of 0.25 mg/ml). (B) Autolysis of Xc cells incubated with each antibody. Xc cells were incubated in autolysis buffer including each purified antibody (final concentration of 0.25 mg/ml). No preimmune sera affected both the chain length and the autolytic activity of the wild-type strain Xc.
