title: Significance of radiographic findings in early-onset group B streptococcal infection.
abstract: Chest radiographs on 73 neonates with early-onset group B Streptococcus (GBS) infection were reviewed. Eighty-six percent of the infants were premature (less than 38 weeks); 68% weighed less than or equal to 1,500 g. In infants weighing less than or equal to 1,500 g, the predominant radiographic pattern was hyaline membrane disease (HMD) (80%). There was a significant increase in radiographic HMD in 1,000 to 1,500-g neonates with GBS infection (77%) when compared to a control group of infants without GBS infection (44%). Mortality in 1,000 to 1,500-g infants with GBS infection and radiographic HMD (95%) was also significantly higher than in the control group of infants with hmd HMD and no GBS infection (38%). In larger premature and full-term infants, the radiographic findings were not specific and also were not helpful in distinguishing GBS infection from other newborn respiratory disorders.
