Agentes bacterianos asociados a brotes de enfermedades transmitidas por alimentos en La Habana, 2006-2010

Abstract

La detección e investigación de los brotes de enfermedades transmitidas por alimentos constituye uno de los principales retos para el Sistema de Salud Pública. Con el objetivo de determinar las bacterias implicadas en los brotes de esta enfermedad en La Habana en el período del 2006 al 2010, se efectuó un estudio descriptivo sobre el aislamiento de bacterias en la investigación de 130 brotes, analizados en el laboratorio de Microbiología de los Alimentos del Instituto de Nutrición e Higiene de los Alimentos. Los aislamientos bacterianos se realizaron teniendo en cuenta las normas vigentes para el análisis de alimentos. Los mayores porcentajes de aislamiento correspondieron a Escherichia coli (25 %), Staphylococcus coagulasa positiva (19,7 %) y Clostridium perfringens (18,4 %). En el 17 % de los brotes estudiados se determinó la presencia de dos microorganismos. Las bacterias patógenas más frecuentes causantes de brote fueron Staphylococcus coagulasa positiva, aisladas en la mayoría de los casos de productos de repostería elaborados con cremas, y C. perfringens, que es causa de brotes por el consumo de carne y productos cárnicos en salsas. En un brote se aisló Salmonella y Staphylococcus con recuentos mayores de 10(5) UFC/g, elementos que demuestran la importancia de los ensayos de laboratorio para definir el agente causal en el estudio de un brote.
