Observations and comments concerning the isolation of group B beta-hemolytic streptococci from human sources.
A marked increase in the isolation of Group B streptococci from patients in the University Hospital, Saskatoon, has been noted over the past four years, and no change in technical methods has been found to explain this increase. Group B streptococci have been isolated from 242 patients, in 53 of whom the streptococcus was considered the cause of the infection. Infections occurred predominantly in the urinary tract, female genital tract and upper respiratory tract. There was a low incidence of infections in newborn infants, and only four infections were in patients under 1 year old. Infections were more frequent in women than men and in patients over 40 years of age. No particular affinity of Group B streptococci for diabetics was demonstrated.
