Serogroup B, electrophoretic type 15 Neisseria meningitidis in Canada.

Invasive meningococcal disease is nationally reportable in Canada. In recent years, a serogroup C genotype, designated electrophoretic type 15 (ET15), has been the most frequently isolated meningococcal genotype in Canada and has caused epidemics across the country. Between August 1993 and September 1995, there were 9 cases of invasive meningococcal disease caused by a variant of this genotype,...

Epidemiology of serogroup B invasive meningococcal disease in Ontario, Canada, 2000 to 2010

BACKGROUND Invasive meningococcal disease (IMD) caused by serogroup B is the last major serogroup in Canada to become vaccine-preventable. The anticipated availability of vaccines targeting this serogroup prompted an assessment of the epidemiology of serogroup B disease in Ontario, Canada. METHODS We retrieved information on confirmed IMD cases reported to Ontario's reportable disease databas...

New Endemic Legionella pneumophila Serogroup I Clones, Ontario, Canada

The water-borne pathogen Legionella pneumophila serogroup 1 (Lp1) is the most commonly reported etiologic agent of legionellosis. To examine the genetic diversity, the long-term epidemiology, and the molecular evolution of Lp1 clinical isolates, we conducted sequence-based typing on a collection of clinical isolates representing 3 decades of culture-confirmed legionellosis in Ontario, Canada. A...

Serogroup B meningococcal disease--Oregon, 1994.

In Oregon, the incidence of meningococcal disease has increased substantially, more than doubling from 2.2 cases per 100,000 persons in 1992 to 4.6 per 100,000 in 1994--the highest incidence in Oregon since 1943. This incidence was almost fivefold higher than recent estimates for the United States during 1989-1991 (approximately one case per 100,000 persons annually) (1). This report describes ...
