Abstract

The production of pyrogenic exotoxins SpeA, SpeB, and SpeC by group A streptococci has been associated with streptococcal toxic shock syndrome. Several epidemiological studies using DNA hybridization and PCR analysis have been performed in attempts to correlate one or several of the toxins with streptococcal toxic shock syndrome. The results reveal great variation in the occurrence of the speA and speC genes among clinical isolates. In this study, we show that the speC gene could be detected by nested PCR in five Swedish T1M1 strains isolated from patients infected with group A streptococci as well as in three Norwegian T1M1 isolates, previously reported to lack speC as determined by dot blot hybridization. To verify the identities of the amplified products, the nucleotide sequences of the PCR fragments from one Swedish T1M1 strain and from the toxin reference strain NY5 were determined. The nucleotide sequences showed that the amplified products were speC and of allele type C2, on the basis of the nucleotides in positions 438 and 456. However, one additional base pair substitution was found in NY5 at position 147 and in the Swedish isolate at position 157, which resulted in nonsynonymous amino acid changes. Thus, these speC genes represent two new allelic variants.
