Resumen
El aumento de la población ha llevado a una mayor demanda de ambientes naturales para la recreación, pero también ha causado un incremento en la contaminación fecal en aguas recreativas. Esta contaminación puede provenir de animales domésticos y salvajes, así como de prácticas inadecuadas de higiene por parte de los bañistas. La contaminación fecal introduce microorganismos patógenos en el agua, como Salmonella spp., Campylobacter spp, Shigella spp, cepas de Escherichia coli enteropatogenas, entre otros; que pueden causar enfermedades gastrointestinales. Este estudio exploratorio evaluó la relación de E. coli con patógenos bacterianos en aguas recreativas naturales. Para ello, se realizó una búsqueda en bases de datos como Web of Science, Science Direct y SpringerLink de artículos que determinaran al tiempo a E. coli y patógenas bacterianos en muestras de aguas recreativas. Los resultados obtenidos muestran prevalencias y recuentos más altos de algunos patógenos como Vibrio parahemolitycus, Aeromonas spp, Campilobacter spp, Acinetobacter sp, Clostridium perfringens y Pseudomonas spp y en relación con las prevalencias de E. coli para algunos patógenos como Salmonella spp y Shiguella spp fueron parecidas o más bajas. Esto cuestiona el uso de E. coli como indicador para algunos patógenos asociados con la contaminación de origen fecal. En conclusión, este estudio evaluó la utilización de E. coli como un indicador en la determinación de la calidad del agua en áreas recreativas. Estos hallazgos contribuyen al conocimiento existente sobre la importancia de evaluar el uso de E. coli como indicador microbiológico en la evaluación de la seguridad del agua en áreas recreativas.
Population growth has led to greater demand for natural environments for recreation, but has also caused an increase in fecal contamination in recreational waters. This contamination can come from domestic and wild animals, as well as from inadequate hygiene practices by bathers. Fecal contamination introduces pathogenic microorganisms into the water, such as Salmonella spp., Campylobacter spp., Shigella spp., enteropathogenic Escherichia coli strains, among others, which can cause gastrointestinal diseases. In this study, the relationship of E. coli with bacterial pathogens in natural recreational waters was evaluated. To do this, a search was carried out in databases such as Web of Science, Science Direct and SpringerLink for articles that determined both E. coli and bacterial pathogens in recreational water samples. The results obtained show higher prevalences and counts of some pathogens such as Vibrio parahemolitycus, Aeromonas spp, Campylobacter spp, Acinetobacter spp, Clostridium perfringens and Pseudomonas spp in relation to the prevalences of E. coli and for some pathogens such as Salmonella spp and Shiguella spp they were similar. or lower. This questions the use of E. coli as an indicator for some pathogens associated with fecal contamination. In conclusion, this study evaluated the use of E.coli as an indicator in determining water quality in recreational areas. These findings contribute to existing knowledge on the importance of evaluating the use of E. coli as a microbiological indicator in the assessment of water safety in recreational areas.
