DURING recent years, an increased incidence of group B streptococcal infection has been reported in newborn infants. Two distinct types have been described.1,2 The early-onset disease occurs within 24 hours after birth, is characterized by respiratory distress and septicemia, and is often fatal. The late-onset disease usually occurs between 1 and 12 weeks of age, presents as meningitis, and has a better prognosis. Asymptomatic bacteremia, osteomyelitis, septic arthritis, cellulitis, ethmoiditis, conjunctivitis, and pneumonia with empyema have also been reported.3 Urine cultures have occasionally been reported as positive as an associated finding.4 We report a case of lateonset urinary tract infection due to group B streptococcus, unassociated with septicemia or meningitis, and with unusually severe metabolic disorders and urinary tract structural anomalies.
