Bacterial meningitis caused by the strains of Haemophilus influenzae type B resistant to most penicillins and cephalosporins

In recent years bacterial meningitis caused by Haemophilus influenzae appears to have occurred more frequently in Poland. In this paper the author presents three specific cases treated in one typical month at the Department of Neuroinfections at John Paul the II Hospital, Kraków. Each of the cases in question proved difficulty to treat because the strains of bacteria encountered were resistant to the most of penicilins and cephalosporins.
