Determination of bacterial human pathogens in irrigation water of the savannah of Bogota high watershed ; Determinación de la presencia de bacterias patógenas para el humano en aguas de riego en la cuenca alta de la sabana de Bogotá; D.C. Colombia
Objective: To determine the presence of bacterial human pathogens in irrigation water of the savannah of Bogota high watershed. Materials and methods: Samples were collected from 8 municipalities, 8 of which were randomly selected for a number of tests including detection of total coliforms via filtration membrane, Most Probable Number (MPN) for fecal coliforms; isolation on selective media and biochemical identification using the BD-BBL CRYSTAL system. Results: Direct or diffuse fecal contamination approached 41.7% of selected samples while aquatic-terrestrial normal flora the remaining 58.3%... Mehr ...

Objective: To determine the presence of bacterial human pathogens in irrigation water of the savannah of Bogota high watershed. Materials and methods: Samples were collected from 8 municipalities, 8 of which were randomly selected for a number of tests including detection of total coliforms via filtration membrane, Most Probable Number (MPN) for fecal coliforms; isolation on selective media and biochemical identification using the BD-BBL CRYSTAL system. Results: Direct or diffuse fecal contamination approached 41.7% of selected samples while aquatic-terrestrial normal flora the remaining 58.3%. According to the percentage of E.coli and count of total coliforms, the analyzed water is not suitable for agricultural use and represents a risk for human health. ; Determinar la presencia de bacterias patógenas para el humano en aguas de riego en la cuenca alta de la Sabana de Bogotá, Colombia. Materiales y métodos: Se recolectaron 21 muestras en 8 municipios, 8 fueron seleccionadas de forma aleatoria para la determinación de coliformes totales mediante filtración por membrana, número más probable (NMP) para coliformes fecales, aislamiento en medios selectivos e identificación bioquímica con el sistema BDBBL CRYSTAL. Resultados: Se encontró contaminación fecal directa y/o difusa en el 41.7% de muestras y en el 58.3% restante flora normal acuático-terrestre. El porcentaje de E.coli hallado y el recuento de coliformes totales indican que el agua analizada no es apta para el uso agrícola y representa riesgo para la salud.
