Analysis of the gene of Vibrio hollisae encoding the hemolysin similar to the thermostable direct hemolysin of Vibrio parahaemolyticus.
The gene (designated as Vh-tdh) of Vibrio hollisae 9041 encoding a hemolysin similar to the thermostable direct hemolysin (TDH) of V. parahaemolyticus contained a 567-base-pair open reading frame (ORF), which was 93.3-93.5% homologous to those of the tdh genes of V. parahaemolyticus, V. cholerae non-01, and V. mimicus encoding TDH or similar hemolysins. Comparative analysis of the nucleotide sequence containing the Vh-tdh ORF with published nucleotide and amino acid sequences suggested that the Vh-tdh gene and other tdh genes diverged from a common ancestral gene, that the divergence was closely associated with the evolutionary divergence of V. hollisae from other species of genus Vibrio, and that strain-to-strain variation of the Vh-tdh gene exists in V. hollisae.
