“…In addition, while protozoans are important from a public health perspective, waterborne outbreaks of bacterial etiology remain a substantial concern in the United States as well (Craun et al 2005). Salmonella bacterial infections alone are responsible for over 40,000 cases of illness yearly (CDC 2008), and though the disease is most commonly foodborne, a recent salmonellosis outbreak linked to drinking water in Colorado indicates that waterborne transmission is still of concern (Berg 2008).…”

The appropriateness of indicator organisms as surrogates for human pathogens in water quality modeling is dependent on similarities in both presence and transport behavior; however, very little data relating indicator and bacterial pathogen transport behavior in receiving waters is available. In this study observations of presence, partitioning behavior (i.e. association with settleable particles) and removal by upland detention basins were used to assess the suitability of six indicator organisms as surrogates for Salmonella spp. bacteria in an urban watershed.The fecal indicator bacteria (fecal coliforms, E. coli and enterococci) were most closely correlated with Salmonella in terms of presence and partitioning behavior (25-35% associated with settleable particles on average); however, further resolution of the variability associated with Salmonella partitioning is required. Higher removal of particle-associated microbes relative to the total microbial concentration by the detention ponds suggests that sedimentation may be an important removal mechanism. However, large fluctuations in pond performance between storm events and occasional net microbial exports in effluents indicate that these best management practices (BMPs), as currently implemented, will be unlikely to achieve water quality objectives.

ResumenLas mejoras en el suministro de agua son oportunidades para solucionar problemas de Salud Pública. De ahí la importancia de establecer modelos de evaluación y gestión integral que garanticen su calidad. Actualmente hay múltiples metodologías para detectar la contaminación microbiana del agua. Sin embargo, los elevados costos que representan, los tiempos de análisis y aislamiento en cultivo de microorganismos, han sido obstáculo para establecer la calidad microbiana del agua para consumo humano. El uso de microorganismos bioindicadores de calidad del agua disminuye los costos y facilita la implementación de medidas eficientes de tratamiento, control del agua y de enfermedades asociadas a su transmisión. El objetivo de la revisión fue describir los principales indicadores microbiológicos empleados para la evaluación del agua potable, como elementos clave para proponer un nuevo esquema de monitoreo en Colombia. Los resultados permiten considerar como bioindicadores, además de las bacterias y protozoos establecidos en la norma, algunos agentes microbianos como virus u otras bacterias y parásitos. Por otro lado indican la necesidad de establecer valores de referencia y definir los microorganismos a emplear con base en evaluaciones específicas de la situación microbiana del agua en monitoreos de validación, operación y verificación. Esta revisión aporta información importante para la actualización de la norma colombiana con base en el conocimiento de estándares internacionales, nacionales y locales.----------Palabras clave: calidad del agua, agua potable, contaminación del agua, enfermedades relacionadas con el agua, indicadores de contaminación Revisión de tema

Introduction: Shiga toxin-producing Escherichia coli (STEC) infections are the leading cause of hemolytic uremic syndrome (HUS). STEC is the most common cause of acute kidney disease, responsible for 20% of renal transplants in Argentina. Methodology: In 2007, an epidemiological survey was conducted among 883 students from the fifth and sixth years of elementary education in the public schools of San Martin City, Buenos Aires, Argentina. Degree of exposure to the known risk factors previously detected in the region as primary causes of STEC infections was evaluated. Risk factors assessed included consumption of hamburgers, poor personal hygiene, and exposure to various types of drinking and recreational water. The study was designed to evaluate exposure to risk factors for STEC infections among different socioeconomic groups. Results: Ninety-five percent of children surveyed reported consumption of hamburgers. Most of these hamburgers were precooked. Children of high and medium strata attended private swimming-pools, while children from the low stratum attended public pools. Only 30.2% of students washed their hands after going to the toilet and only 43.5% reported hand-washing before eating. Conclusions: Students demonstrated high levels of exposure to identified risk factors for STEC infections. Reduction of these risks will require cultural changes aimed at decreasing morbidity caused by food-borne infections. Institutional framework must provide the necessary resources to implement these changes and emphasize the importance of good personal hygiene. Health education must be implemented to increase food safety awareness of the consumers.
