We studied the epidemiology of S. pneumoniae in the Provence region of
France. Fourteen laboratories provided extensive data on the 516 isol
ates from 460 patients throughout the year 1995. Penicillin resistance
was studied according to sex (293 males,165 females), age (187 childr
en) and serotype. It was then compared to published data. We finally s
tudied the performance of screening test for sensitivity to penicillin
and cefotaxime, by using disks loaded with oxacillin (1 and 5 mg/l) a
nd loracarbef. We confirm the increasing prevalence of penicillin resi
stance among pneumococci (29%) and the multiresistant nature of strain
s with diminished sensitivity to penicillin. Amoxicillin and cefotaxim
e remained active (2% and 0.2% of resistant strains, respectively).
