ABSTRACT

With the purpose to determine the epidemiological trends in the etiology and frequency of causal agents of bacterial meningitis, we made a retrospective review of all confirmed cases, attended in the Infectious Diseases and Specialities Hospitals at La Raza Medical Center from 1980 to 2004 inclusive. In the total of 2940 cases, in this period of study, we found: 1) A progressive diminution in the total number of cases, more evident from 1996 and in the pediatric age groups. 2) A progressive diminution in the frequency and number of etiological agents previously predominants: Enterobacteriaceae, Mycobacterium, Cryptococcus (p ‹ 0.01). 3) No isolation of Haemophilus influenzae in the last 3 years of the study. 4) A tendency to highest isolation of Staphylococcus and other opportunistic agents (p ‹ 0.01). 5) Stability in the trends of isolation of Streptococcus, Enterococcus, Pseudomonas and Candida albicans (p ‹ 0.01). 6) Sporadic, irregular and low prevalence isolation of Neisseria meningitidis type C and Listeria monocytogenes.
