We generated LOS-based conjugate vaccines that elicited bactericidal antibodies in animal models," researchers in the United States report. "However, epitopes on the LOS recognized by the functional anti-LOS antibodies remain unidentified. In this study, a mutant strain, D4, which lost the recognition by a bactericidal anti-LOS rabbit serum in Western blotting was generated from a serotype C strain 26404 by random transposon mutagenesis.
