| epidemic of group a streptococcus m/emm59 causing invasive disease in canada. | the incidence of invasive group a streptococcus (gas) disease can vary over time and geographic region, possibly reflecting the population's susceptibility to particular strains but also variation in the predominant m/emm types. canadian surveillance documented an epidemic of an uncommon m/emm59 type from 2006 to 2009. | 2010 | 21034198 |
| invasive group a streptococcal disease in alberta, canada (2000 to 2002). | invasive group a streptococcal (igas) disease was placed under surveillance in alberta in august 1999. the purpose of this study was to determine the incidence rates of igas infections throughout alberta over a 3-year period (2000 to 2002) and to better understand the epidemiology of igas in this province. there were a total of 441 cases of invasive gas disease over the 3 years examined (average population over 3 years, 3,055,765) and 47 deaths. the incidence in alberta was 5.0 (2000), 5.7 (2001 ... | 2005 | 15814984 |

| m types of group a streptococcal isolates submitted to the national centre for streptococcus (canada) from 1993 to 1999. | the national centre for streptococcus (ncs) (canada) determined the group a streptococcal (gas) m types of 4,760 canadian isolates submitted between 1993 and 1999 by classic serotyping. the 10 most frequently identified m types were m1 (26.4%), m12 (9.8%), m28 (8.9%), m3 (6.8%), m4 (6.2%), m11 (4.8%), m89 (3.1%), m6 (3.0%), m2 (2.6%), and m77 (1.9%). nontypeable isolates accounted for 15.4% of the collection. the province of ontario submitted 51.1% of the isolates, followed by quebec (21.2%) and ... | 2002 | 12454137 |
| varicella-associated invasive group a streptococcal disease in alberta, canada--2000-2002. | we determined the incidence of invasive group a streptococcal (gas) disease among children < or =14 years of age in alberta, canada, with a focus on infections associated with varicella. during 2000-2002, there were 71 cases of invasive gas disease among patients in this age group. fourteen cases occurred in children with varicella (19.7%), for an annual incidence of 0.73 varicella-associated cases per 100,000 children. necrotizing fasciitis was not noted in patients with invasive gas disease an ... | 2005 | 15825001 |
