[Serratia marcescens bacteremia in a neonatal intensive therapy center: epidemiological study].

The Authors have isolated Serratia marcescens in nine coltures of blood, effected during the period Genuary 1 - February 28, 1979, in a newborn nursery. They have carried an epidemiologic study in immature ward, in newborn children and sanitary personnel. Extensive cultures of objects, equipment and air were negative for Serratia marcaescens. The exact mode by which Serratia was introduced into the immature ward could not be determined. The Authors point out on importance of contamination in newborn children by @opportunist" Gram-negative bacilli.
