2003 MAR 12 - (NewsRx.com & NewsRx.net) -- M protein gene type distribution among group A streptococcal clinical isolates recovered in Mexico overlaps with type distribution within the United States.
According to a study from the United States, "To examine the type distribution of pathogenic group A streptococcal (GAS) strains in Mexico, we determined the emm types of 423 GAS isolates collected from ill patients residing in Mexico (Durango or Mexico City). These included 282 throat isolates and 107 isolates from normally sterile sites. Of the other isolates, 38 were recovered from other miscellaneous infections."
"A total of 31 different emm types were found, revealing a broad overlap between commonly occurring emm types in Mexico and the United States," reported Luz Elena Espinosa and colleagues at the Hospital Infantil de Mexico 'Federico Gomez' in Mexico and the U.S. Centers for Disease Control and Prevention in the United States.
Espinosa and coauthors concluded, "The information obtained in this study is consistent with the possibility that multivalent, M type-specific vaccines prepared for GAS strain distribution within the United States could ...
