In Reply.  —In our study, we reported that a highly virulent group A streptococcal clone (PFGE-1) caused multiple cases of invasive streptococcal disease in a small community from January through March 1995. Fifty-nine (32%) of 187 children attending the only elementary school in this community carried group A streptococcus organisms in their throats, and in 46 (78%) of the 59 carriers, the PFGE-1 clone was isolated. All 59 children who carried group A streptococcus were offered antimicrobial therapy, and all were treated. No additional cases of invasive disease caused by the PFGE-1 clone occurred in this community at the conclusion of this intervention. However, no follow-up pharyngeal cultures were performed to determine whether the prevalence of the PFGE-1 among these carriers decreased following antimicrobial therapy.Even if one assumes an eradication rate among the PFGE-1 streptococcal carriers in our study similar to that reported by Drs Perry and Maher (83%), other factors
