Four hundred and ninety nine children (aged between one month and five
years) admitted with clinical features of meningitis were recruited i
n cross-sectional survey of bacterial meningitis in hospitals within N
airobi. Lumbar punctures were done on all of them and the cerebrospina
l fluid (CSF) analysed bacteriologically and serologically for the com
mon causative organisms. Two hundred and fifty (50.1%) cases were diag
nosed clinically as having meningitis. Of these, 132 (52.8%) had turbi
d CSF specimens, while 118 (47.2%) were clear. When turbid CSF specime
ns were cultured, 83 (62.8%) yielded three common bacterial micro-orga
nisms namely; Neisseria meningitidis, Streptococcus pneumoniae and Hae
mophilus influenzae in that order of frequency. The implications of th
ese findings in paediatric meningitis together with the drug sensitivi
ty patterns is presented and discussed.
