FIG 6.

Enzyme-linked immunosorbent assays (ELISAs) to detect relative amounts of K antigen capsular polysaccharide (A) and anionic polysaccharide (B) in the wild type (W83) and the ΔdhsphK1 mutant. Lower levels of K antigen capsule were detected in the ΔdhsphK1 mutant than in the parent strain, and yet, the level of APS was not altered. Number of repeats (n), 3. Error bars shown in the graph were calculated using the following formula: SE = SD/√n, where SE is the standard error of the sample, SD is the standard deviation of the sample, and n is the number of samples.
