Fig. 5From: Surface antigens contribute differently to the pathophysiological features in serotype K1 and K2 Klebsiella pneumoniae strains isolated from liver abscessesSerum bactericidal assay of Klebsiella pneumoniae wildtype strains and their mutants. a STL43 serotype O1:K1 wild type, STL43Δwzy K-antigen-deficient mutant, STL43ΔwbbO O-antigen-deficient mutant. (asterisk) STL43 vs STL43ΔwbbO (P = .004). b TSGH69 serotype O1:K2 wild type, TSGH69Δwzy K-antigen-deficient mutant, TSGH69ΔwbbO O-antigen-deficient mutant. (asterisk) TSGH69 vs TSGH69Δwzy, and TSGH69 vs TSGH69Δwbbo (for both, P = .006). Chi square test statistical analysis was carried out for at least two successive tests in each isolate. The values are the mean ± standard deviationBack to article page
