Mutations in the lspA1 and lspA2 Genes of Haemophilus ducreyi Affect the Virulence of This Pathogen in an Animal Model System

Volume 71, no. 5, p. 2478-2486, 2003. Page 2481, column 2, lines 17-22 from bottom: “The outer membrane protein profiles of the wild-type strain 35000HP and the three mutants, as represented by the proteins present in the Sarkosyl-insoluble fraction derived from cell envelopes, were virtually identical with the exception of a 40-kDa antigen that exhibited some variability in its expression among these mutants (data not shown).” should read “The outer membrane protein profiles of the wild-type strain 35000HP and the three mutants, as represented by the proteins present in the Sarkosyl-insoluble fraction derived from cell envelopes, were very similar with the exceptions of some variability in the expression of a 40-kDa antigen among these mutants and reduced expression of the major outer membrane protein (MOMP) (36) in the lspA1 mutant 35000HP.1 and the lspA1 lspA2 double mutant 35000HP.12 (data not shown).”
