title: [Colonization by Streptococcus group B in full term pregnancy and newborns in a community in Venezuela].
abstract: BACKGROUND
  The aim of this study was to define the incidence of cervico-vaginal colonization by group B Streptococcus (SGB) in full term pregnancy as well as vertical and horizontal transmission in newborns attended in two public hospitals in Valencia, Venezuela.
  
  
  METHODS
  An study cervico-vaginal exudates from 171 full term pregnant women was performed together with general obstetric survey. Oropharyngeal and nasal exudate studies in 118 newborns of the mothers studied were carried out during the first 12 hours after birth as was a neonatologic survey.
  
  
  RESULTS
  The global percentage of maternal colonization by SGB were 32.7% while in the NB it was 45.8%. Among the NB colonized by SGB 73.2% were considered to have acquired the bacteria from the mother (vertical) with no significant differences in the data found in the two hospitals. The rate of horizontal colonization of the newborns was 42.3% in one hospital and only 8% in the second.
  
  
  CONCLUSIONS
  There were no significant statistical differences between the rate of cervico-vaginal colonization in women attended in two public hospitals in Venezuela. No differences were observed in the rate of vertical colonization of newborns but to the contrary, that of the horizontal (nosocomial) colonization was of 42.3% and 8% in the Charity and University Hospitals, respectively.
