serotypes of streptococcus agalactiae cultured from dairy milk samples in québec.streptococcus agalactiae remains an important pathogen of dairy herds in québec, but data about antigenic characteristics of this microorganism are sparse. this study was conducted to determine the variety of s. agalactiae serotypes in dairy herds in québec. two hundred and ninety-five isolates cultured from the milk of individual cows from 7 regions of québec were serotyped. sixty-two percent of the isolates were untypable. among the 38% of typeable isolates, serotype iii was found most frequen ...200312677690
management practices associated with the bulk-milk prevalence of staphylococcus aureus in canadian dairy farms.when designing mastitis-prevention and control programs, it is important to know the level of adoption of mastitis-prevention management practices and control programs and the herd-level prevalence of contagious mastitis pathogens. our objectives were to estimate: (1) adoption of recommended mastitis-preventive management on canadian dairy farms; (2) herd-level prevalence of contagious mastitis pathogens on canadian dairy farms; and (3) associations of certain management practices with the isola ...201020696486

characterization of streptococcus agalactiae isolates of bovine and human origin by randomly amplified polymorphic dna analysis.streptococcus agalactiae is considered one of the major causes of bovine intramammary infections. it is also found in the vaginas of women without any apparent clinical symptoms, but reports of neonatal infections, causing significant morbidity, are relatively frequent. the aim of this study was to evaluate the genetic diversity of s. agalactiae strains isolated from bovine milk and from asymptomatic women in québec, canada, by randomly amplified polymorphic dna (rapd) analysis. a total of 185 b ...200010618066
group b streptococcal necrotizing fasciitis and streptococcal toxic shock-like syndrome in adults.necrotizing fasciitis, which is a severe and uncommon infection involving the subcutaneous tissues, is usually caused by group a streptococci. to our knowledge, however, group b streptococci (streptococcus agalactiae) have been reported to cause necrotizing fasciitis in only 4 instances (2 involving neonates) over the past 4 decades. we report 3 cases of group b streptococcal necrotizing fasciitis in adults that occurred in southern ontario and quebec within a 10-month period. all 3 patients had ...19989701105
