Resumen
Salmonella enterica es uno de los principales patógenos transmitidos por los alimentos en el mundo, siendo la primera causa de brotes de intoxicación alimentaria en Chile. A pesar de todos los esfuerzos de control y prevención desplegados, la incidencia en las personas se ha mantenido alta, por lo que diversos factores podrían estar influenciando el comportamiento epidemiológico de esta infección. El objetivo de esta revisión es describir factores referidos tanto al agente biológico, al hospedero humano y al medio ambiente, que podrían tener mayor trascendencia en Chile. De esta forma, se infieren ámbitos prioritarios para la investigación de S. enterica, que permitan entender su dispersión en la naturaleza y su éxito como patógeno de un amplio rango de hospederos. A futuro, el mayor conocimiento de estos determinantes facilitará la implementación de estrategias de bioseguridad y vigilancia para la prevención de la enfermedad en las personas y en los animales.
Salmonella enterica is a major foodborne pathogen worldwide, being the main cause of outbreaks by food consumption in Chile. Despite all efforts deployed for control and prevention, the high incidence in people still persists, with several factors that could be influencing the epidemiological behavior of this infection. The objective of this review is to identify these factors belonging to the biological agent, the human host and the environment, which probably have a greater importance in Chile. Thus, priority areas for research of S. enterica are inferred, which hopefully will help to understand its spread in nature and its success as a wide host range pathogen. In the future, increased understanding of these determinants will facilitate the implementation of biosecurity and surveillance strategies for the prevention of disease in people and animals.
