Abstract

To explore whether a novel staphylococcal clone or structural variant of toxic shock syndrome toxin 1 is associated with Kawasaki syndrome, six toxigenic strains of Staphylococcus aureus from Kawasaki syndrome patients were studied. The strains were divisible into two groups based on phenotypic and genotypic characteristics and are therefore unequivocally not clonal. Portions of the tstH genes of each strain were sequenced. Three were sequenced in their entirety, while the remainder were sequenced from codon 66 to codon 137 of the mature protein only. Two of the former group differed slightly in the sequences of their signal peptides relative to the sequence published for the tstH signal peptide. Those differences did not affect toxin processing or secretion. The sequenced portions of the regions encoding mature toxic shock syndrome toxin 1 were identical in all six strains and corresponded exactly to the published sequence of tstH. No evidence was found for the existence of a structural variant of tstH uniquely associated with Kawasaki syndrome.
