abstract: 878 strains of Streptococcus pneumoniae were tested during two periods : 667 strains from 1972 to 1977 and 211 strains during 1978. Strains were isolated from spinal fluids, blood, peritoneal fluids, urines, exudate from respiratory tract except sputum. In polymicrobial specimens, only the predominant species were serotyped. From 1972 to 1977, 53,3% of strains are typed and 6 serotypes and pools are prevalent among 68,5% of typed strains, the most frequent are : 6 - D - 18 - 19. During the second period (1978) 82,5% of strains are typed, 9 serotypes are prevalent among 68,5% of typed strains, the most frequent are : 6 - 19 - 23 - 3. During 1978, 27,6% of strains are isolated from child wards, others from adults wards. A comparison of the relative frequencies of the serotypes in the two wards shows that the following 10 serotypes are the most frequent: 6 - 19 - 23 - 3 - 18 - 1 - 8 - 9 - 14 - 4.
