&NA;Haemophilus influenzaemeningitis in the presence of a cerebrospinal fluid shunt has been reported uncommonly.Staphylococcus aureusandStaphylococcus epidermidis,the most common etiological agents, are usually acquired by contiguous spread from an intraoperative or perioperative source. These infections usually occur within 2 months of shunt insertion and are rarely associated with bacteremia. Review of the literature shows that infection withH. influenzaetypically occurs later than with the more common pathogens, is commonly associated with bacteremia, and frequently can be treated with antibiotics alone.
