MicrobiologicaI characterization of particle material as a risk: factor for the health of the community of Puente Aranda

Abstract

During the last 14 years, the predominance of Acute Respiratory Infection (I RA), in children under 14, who live in the neighborhood of Puente Aranda (Bogota, Colombia), has been related, through epidemiological studies, with high concentrations of PM1 0 that exceed or approach the air quality standard established by the Departamento Tecnico Administrativo del Medio Ambiente (DAMA). That is why a Microbiological study of particle materials was performed at the location using both direct impact and suction methods for the collection of bacteriological samples. The utilization of the Merck Air. Sampler (MAS-1 00) provided reliability in the sampling process. Within the particle material the most likely opportunist pathogens were identified. These pathogens are present in air currents and take advantage of the effects of lacerations and irritations on the epitheliums caused by particles. They add to the sedimentation of the cilia network that protect the respiratory system and provide appropriate conditions for the incoming micro-organism to cause respiratory problem
