RESUMO
Introducción Se describe la investigación de un brote por Listeria monocytogenes en una Unidad de Neonatos. Métodos Se realizó una encuesta epidemiológica, recogida de muestras ambientales y estudio de epidemiología molecular. Resultados Se trata de un brote nosocomial de infección por L. monocytogenes, confirmado por epidemiología molecular, en una Unidad de Neonatos que afectó a tres niños. La cadena de transmisión no pudo ser confirmada, pero se sospecha una transmisión cruzada vehiculizada por las manos del personal. Conclusión La estricta adherencia a las medidas de prevención estándar es necesaria para evitar estos brotes nosocomiales (AU)
