BACTERIOLOGICAL ASPECTS OF PURULENT-MENIN GITIS IN BAMAKO-DISTRICT UPON 1,541 STRAINS COLLECTED FROM 1979 TO 1991

This study is about bacteriological aspects of purulent meningitis in Bamako area upon 1,541 strains collected from 1979 to 1991. It showed that N. meningitidis, S. pneumoniae and H. influenzae b are responsibl e. In general, N. meningitidis is the most frequent, but this depends on years and months. Since 1988, N. meningitidis serogroup C has suppl anted serogroup A. N. meningitidis is predominant between 7 to 30 year s, S. pneumoniae between 1-28 days and 31 to 68 years, H. influenzae b etween 1 month to 6 years. The frequency of these species is the same in male and female. The 3 species are quite sensitive to antibiotics t ested except sulphonamides and cotrimoxazole. Meanwhile, the appearanc e of strains of S. pneumoniae to penicillin and H. influenzae to ampic illin must be followed with interest to check any time the importance of the phenomenon.
