CSF and blood cultures confirmed beta-lactamase-negative ampicillin-resistant (BLNAR) Haemophilus influenzae type b meningitis susceptible to ceftriaxone, meropenem, and cefotaxime, so it was decided to continue with intravenous ceftriaxone (200 mg/kg/day) and dexamethasone. Here, LACTB is linked to meningitis.
