| dna fingerprints of streptococcus pyogenes are m type specific. | dna from group a streptococci of various m and t types was cleaved with endonucleases to produce a dna fingerprint. comparison of dna fingerprints proved to be a very useful tool for studying the epidemiology of isolates from various outbreaks of streptococcal disease. patterns of dna fragments from hindiii digests of samples of total dna were conserved among strains of the same m serotype yet were easily distinguished from those of different m serotypes. different m types were associated with s ... | 1988 | 3058817 |
| Invasive group A streptococcus in a skilled nursing facility--Pennsylvania, 2009-2010. | In September 2010, the Pennsylvania Department of Health was notified of a cluster of invasive group A Streptococcus (GAS) infections among residents of a skilled nursing facility specializing in neurologic and pulmonary care.

| invasive group a streptococcus carriage in a child care centre after a fatal case. | after a fatal case of invasive group a streptococcal disease, serotype t-1, in a child care centre, group a streptococcal t-1 prevalence was measured and risk factors for carriage were determined. a total of 87% (224/258) had throat culture tests. group a streptococcus was isolated from 57 (25%), and of the 50 isolates serotyped, 38 (76%) were t-1. group a streptococcal t-1 prevalence was 18% (38/217) and six of nine rooms had children with group a streptococcal t-1 isolates. the risk of group a ... | 1994 | 7979524 |
