antibodies to capsular polysaccharides of group b streptococcus in pregnant canadian women: relationship to colonization status and infection in the a cohort study of 1207 pregnant women in alberta, canada, the serotype distributions of vaginal-rectal group b streptococcus (gbs) isolates were compared with all isolates from neonates with invasive gbs disease identified by population-based surveillance. serum concentrations of ia, ib, ii, iii, and v capsular polysaccharide (cps)-specific igg also were determined, according to serotype of the vaginal-rectal colonizing gbs strain. gbs colonization was detected in 19.5% (235 of 1207) of women ...200111443553
risk factors for early-onset group b streptococcal disease in neonates: a population-based case-control study.infection with group b streptococcus (gbs) is a major cause of neonatal illness and death. we examined the antenatal and perinatal risk factors for early-onset gbs disease among neonates.200312900477

neonatal septic assess and correlate the microbiology of neonatal septic arthritis with the clinical presentation, we reviewed the records of nine infants with neonatal septic arthritis (nsa) diagnosed at edmonton hospitals between 1964 and 1981, and evaluated 92 other cases reported in the english literature since 1960. our analysis revealed that the microbiology of nsa seemed to be dependent on whether it was hospital or community acquired. in the hospital-acquired cases, staphylococci were the predominant ...19836363350
physicians' prevention practices and incidence of neonatal group b streptococcal disease in 2 canadian regions.the impact of expert guidelines on the prevention of neonatal group b streptococcal (gbs) disease has not been studied in canada. our aim was to determine physician practices with regard to this condition before and after publication of canadian guidelines and to monitor concurrent trends in the incidence of neonatal gbs disease.200111233867
multilocus sequence types associated with neonatal group b streptococcal sepsis and meningitis in b streptococci (gbs), a leading cause of neonatal sepsis and meningitis, are transferred to neonates from colonized mothers during childbirth. prior studies using multilocus sequence typing (mlst) have found specific gbs clones (e.g., sequence type 17 [st-17]) to be associated with neonatal disease in several geographic locations. few population-based studies, however, have been conducted to determine the frequency of disease caused by specific gbs clones. mlst was used to assess the genet ...200919158264
streptococcus agalactiae mastitis: a review.streptococcus agalactiae continues to be a major cause of subclinical mastitis in dairy cattle and a source of economic loss for the industry. veterinarians are often asked to provide information on herd level control and eradication of s. agalactiae mastitis. this review collects and collates relevant publications on the subject. the literature search was conducted in 1993 on the agricola database. articles related to s. agalactiae epidemiology, pathogen identification techniques, milk quality ...19979220132
population-based active surveillance for neonatal group b streptococcal infections in alberta, canada: implications for vaccine formulation.knowledge of circulating serotypes of group b streptococcus (gbs) is important for formulation of vaccines. there are no canadian data on the serotype distribution of neonatal gbs isolates.200111734768
two-year survey of alberta laboratories processing of antenatal group b streptococcal (gbs) screening specimens: implications for gbs screening programs.we evaluated specimen types received and methods used by laboratories to process screening gbs specimens from pregnant women. surveys during 1995 and 1997 of all laboratories in the province of alberta, canada that culture gbs from screening genital specimens were completed. between surveys, there was dissemination of information about appropriate culture techniques. survey completion rates were 100% in both years (38/38 in 1995 and 20/20 in 1997). during 1995 as compared to 1997, laboratories w ...199910626125
