Figure 5. LOS variation analysis of the strain isolated from the blood culture.

Figure 5

A- Schematic representation of the immunotype L9 LOS of serogroup A Nm Z2491 (adapted from Zhu and coworkers [68] and Choudhury and coworkers [52]). The deletion of the lgtB gene in Z5463BC is predicted to form a truncated LOS lacking the galactose on the terminal GlcNAc. B- Decreased size of the LOS from Z5463BC due to the loss of lgtB. Tricine SDS-PAGE gel of proteinase K LOS extracts from Z5463BC and its parental strains, revealed by silver staining. 1: Z2491 (L9 immunotype), 2: Z5463, 3: Z5463PI, 4: Z5463BC.
