The One Health approach acknowledges the interconnection between human health, animal health, and environmental health, recognizing that these domains are closely intertwined, as many diseases affecting humans are also common in animals. Water acts as a vehicle for the transmission of such diseases, highlighting the significance of monitoring the quality of water intended for human consumption. In 2022, a research study was conducted to evaluate the water quality for human consumption in Bagua, Amazonas Region. The physicochemical analysis indicated that most parameters were within normal range, except for residual chlorine, which was predominantly absent. Microbiological analysis revealed the presence of total coliforms and E. coli. Phenotypic characterization of E. coli isolates exhibited resistance to the several antibiotics, including nalidixic acid, gentamicin, amoxicillin plus clavulanic acid, norfloxacin, and ciprofloxacin. These findings indicate a compromised production of water for human consumption, as per the water quality regulations in Peru. The presence of fecal contamination poses a significant microbiological risk to consumers. These results underscore the breakdown of the human-environment-animal interface within the One Health approach, thereby endangering public health.

The inorganic chemical parameters in drinking water that include heavy metals are substances that exist in nature very widespread, nevertheless toxic metals such as lead, cadmium, arsenic, mercury, are very harmful to human health and to all forms of life, these toxic metals are silents contaminants. Therefore, the present study aims to determine the presence of inorganic chemical parameters in the drinking water from districts of the province of Puno. The results were compared based on the parametric test T-student and the non-parametric tests Kolmogorov-Smirnov. Finding the highest values (mg/L) in districts as Capachica Ba (0.8458) and Pb (0.5255), Mañazo Al (3.08) and Pb (0.0185), San Antonio de Esquilache Fe (0.49) and Pb (0.9513), Vilque As (0.0193) and Pb (15.34), and Pichacani As (0.0193) and Pb (0.0215), as it is observed the samples do not comply with the regulation of the quality of drinking water in Peru, making it unsuitable for human consumption.

This study investigated the presence of antibiotic-resistance genes in drinking water consumed by the university community in the Peruvian Amazon. Water samples were collected from three primary sources: inflow from the distribution network, a storage cistern, and an underground intake. Conventional PCR was employed to detect genes associated with resistance to erythromycin (ermC), ampicillin (amp), ciprofloxacin (QEP), multidrug resistance (marA), and specific multidrug resistance in E. coli (qEmarA). Physicochemical analysis revealed compliance with most regulatory standards; however, groundwater samples showed lead concentrations exceeding legal limits (0.72 mg/L) and lacked residual chlorine. All sampling points tested positive for the evaluated resistance genes, demonstrating the widespread dissemination of resistance factors in drinking water. Contrary to initial expectations, resistance genes were also prevalent in treated sources. These findings reveal a critical public health risk for the university community, emphasising the need for effective disinfection systems and robust monitoring protocols to ensure water safety. The presence of these resistance genes in water is a critical public health concern as it can facilitate the spread of resistant bacteria, reducing the effectiveness of medical treatments and increasing the risk of infections that are difficult to control.

Learning outcomes of physics in university education have difficulties in most cases, especially in skills development. In this investigation, active methodological strategies were applied, through the paired differences test it was concluded that with the experimental method better results were obtained than with problem-based learning in a sample of 8 students, in addition to improving their skills for teamwork and capacity development of high cognitive demand.
