RESUMEN
Una sola salud (USS), es un enfoque integral y unificador diseñado para equilibrar y optimizar la salud tanto de seres humanos, animales y ecosistemas, aprovechando la interrelación entre estos ámbitos para establecer nuevas metodologías de vigilancia y control de enfermedades. Es así como, la forma en que se utiliza el suelo puede influir en el número de casos de malaria; las condiciones meteorológicas y controles artificiales del agua pueden afectar enfermedades como el dengue; el comercio de animales salvajes vivos puede aumentar la probabilidad de que ciertas enfermedades infecciosas se transmitan de animales a humanos (zoonosis), entre otros ejemplos. Es decir, un esfuerzo integrador de múltiples disciplinas que trabajan de manera colaborativa a nivel local, nacional y global en todos los aspectos del cuidado de la salud de los seres humanos, los animales y el medio ambiente. El objetivo de este manuscrito fue reportar y discutir el concepto USS, como nuevo enfoque sanitario inter y transdisciplinario. Debemos adoptar la filosofía de USS desde el nivel global hasta el más local para reducir entre otras, los riesgos de pandemias que pueden ocurrir con mayor frecuencia considerando el crecimiento exponencial de la población mundial y la urbanización.
SUMMARY: One Health (OH) represents a comprehensive and unifying approach designed to balance and optimize the health of humans, animals, and ecosystems. By leveraging the interdependent links among these domains, OH establishes new methodologies for disease surveillance and control. The manner in which land is utilized can influence the incidence of malaria; meteorological conditions and artificial water controls can impact diseases such as dengue, and the trade of live wildlife can escalate the likelihood of certain infectious diseases being transmitted from animals to humans (zoonoses), among other interconnected factors. That is, an integrative effort of multiple disciplines working collaboratively and locally, nationally, and globally in all aspects of health care for humans, animals, and the environment. The aim of this manuscript was to elucidate and discuss the OH concept as an interdisciplinary and transdisciplinary paradigm in healthcare. In conclusion,it is imperative to embrace the OH philosophy from a global to local scale in order to mitigate, among other concerns, the heightened risks of pandemics. This consideration is especially pertinent given the exponential growth of the global population and urbanization trends, which may contribute to an increased frequency of pandemic occurrences.

The aim of the study was to track the spread of antimicrobial resistance among the different sectors of One Health through the detection of Multidrug-Efflux-System in multidrug-resistant Staphylococcus aureus isolates. Multidrug-resistant (MDR) and methicillin-resistant (MRSA) S. aureus isolates were selected: 25 of human, one of animal and eight of food origin. The efflux system genes norA, norB, norC, LmrS, tet38 and msrA were screened by PCR. The activity of the efflux systems was determined by the minimum inhibitory concentration (MIC) of tetracycline and ciprofloxacin in the presence and absence of CCCP and in the quantification of ethidium bromide efflux. Furthermore, biofilm formation was determined in the presence and absence of the CCCP. The molecular epidemiology of the isolates was traced with the aid of PFGE. The gene norC was the most prevalent, detected in all isolates and msrA was the least prevalent, detected in only two isolates from humans. There was no difference in the MICs of tetracycline and ciprofloxacin in the presence of CCCP, but 55.9% of isolates showed ethidium bromide efflux. The presence of CCCP decreased the biofilm formation. Regarding the molecular epidemiology, in three clusters was a mixture of the isolates from different origins. Therefore, S. aureus MDR with active multidrug efflux systems are circulating between One Health domains and it is necessary to consider strategies to decrease this circulation in order to prevent the dissemination of resistance mediated by MES.
