Abstract:We found 31 different emm-toxin genotypes among 74 group A streptococcal isolates causing invasive infections in French children. The predominant emm types were emm1 (25%), emm3 (8%), emm4 (8%), emm6 (7%), and emm89 (9%). Sixteen percent of isolates harbored the streptococcal invasive locus, half of them belonging to emm4.
