DEVELOPMENT OF A COLLECTION OF BACTERIA CAUSING MENINGITIS IN RIO-DE-JANEIRO FROM 1990 TO 1991

From March 1990 to December 1992, the National Institute for Quality Control of Health-INCQS Research Collection received 1476 bacterial samples isolated from human cerebrospinal fluid of patients suspect of meningitis in Rio de Janeiro, from the Sao Sebastiao State Institute of infectious Diseases (IEISS). Neisseria meningitidis was found in most of these materials, followed in smaller number by Haemophilus sp. and Streptococcus pneumoniae. The great majority of N. meningitidis strains was serogrup B, followed by serogroup C and a few strains of serogroup W135. More than 50% of the isolated bacterial agents cal,le from the predominant 0-4 years age group. The majority of the strains were from patients in the region known as ''Baixada Fluminense'' (Low Lands). The aim of the work presented here is to obtain samples of meningitis cases in at least 70% of the State of Rio de Janeiro and develop a collaborative research between INCQS-FIOCRUZ and the IEISS, in order to set up a collection of strains for future studies. However, despite work being carried out in a rather satisfactory way, difficulties still arise and have to be overcome, to survey data.
