RESUMEN
Between January 1986 and December 1991, the sensitivity of germs isolated from purulent meningitidis diagnosed at the Universitary and Hospital Center Treichville was tested with reference to the antibiotics utilized in the treatment of purulent meningitidis (Ampicillin, cefotaxime, amoxicillin+clavulinic acid, chloramphenicol, gentamicin and Trimethoprim-sulfamethoxazole)). Cefotaxime, cephalosporin of the third generation, keeps its effectiveness on the main germs as a whole (Pneumococcus, Meningococcus, haemophilus influenzae). On the contrary, the other antibiotics undergo some fluctuations, or their activities are declining year after year. As far as etiology is concerned, pneumococcus always takes the first place, then come Haemophilus influenzae and Meningococcus.
