Determinación de bacterias entéricas en aguas de consumo doméstico en la ciudad de Machala desde mayo del 2024 hasta febrero del 2025.

Abstract

Escherichia coli is closely related to the transmission of infectious diseases and is an indicator of recent fecal contamination. Its presence highlights the need to implement additional measures to identify and mitigate possible sources of contamination. Objective: The objective of this study was to evaluate the quality of domestic water stored in three types of reservoirs using microbiological techniques to reduce the risk of disease in the parish of El Cambio in the city of Machala. Methods: Presumptive tests (NMP) and confirmatory tests (sowing for the determination of this microorganism) were performed. Conclusion: We were able to evaluate the quality of water for domestic consumption stored in 3 types of reservoirs and the results were compared with the limits established in the Equatorial Technical Standard 1108. Results: The results obtained from the microbiological tests performed on the various types of reservoirs confirmed the presence of Escherichia coli, which is indicative of contamination with feces. This is of concern because it affects the health of the population causing gastrointestinal problems.
