Answer

Hib may be grown from blood cultures in at least 50-80% of cases if the patient has received no prior treatment with antibiotics. Accurate etiologic diagnosis of meningitis may be more complicated in developing countries, where often there is widespread use of antibiotics before blood or CSF cultures can be obtained. This approach is understandable if one considers the delay that may be encountered in some nations in rapidly obtaining access to healthcare facilities capable of performing such studies.
