Newborns’ bacterial infections due to group B Streptococcus (GBS) happen in two forms including early-onset disease or late-onset disease. In this paper, we report a case of early-onset GBS infection in a male infant. A 22-year-old primigravid woman delivers a term normal looking male infant. Nasal flaring, grunting, and poor feeding presented soon after birth. An empiric treatment with intravenous ampicillin and amikacin initiated. On the second day, he was transferred to Newborn Intensive Care Unit (NICU). The intravenous antibiotics were changed to tazocin and vancomycin in NICU. The blood culture (BC) was positive for GBS. After 48 hours, respiratory distress symptoms disappeared, BC was negative, and ABG and CBC became normal. Finally, the infant was discharged after 15 days.GBS is a normal flora of women's gastrointestinal and genitourinary tracts. Infants with early-onset GBS sepsis need very close observation including repeated vital signs evaluation.
