Abstract
Salmonella es el segundo patógeno de importancia en salud pública en número de casos, y el número uno en número de brotes, en la Unión Europea, solo por detrás de Campylobacter. A pesar de ser una bacteria comensal del intestino de numerosas especies homeotermas, puede llegar a causar cuadros clínicos de tipo gastrointestinal o, incluso, extraintestinal, como por ejemplo artritis reactivas o meningitis. Además, Salmonella es una enterobacteria de la que se han aislado cepas resistentes a diferentes antimicrobianos tanto en humanos como en animales, agravando los cuadros clínicos observados al no ser eficaz el tratamiento. En la actualidad, la resistencia a antimicrobianos representa el mayor reto al que se enfrenta la medicina occidental del siglo XXI, pues ocasiona fallo terapéutico en miles de casos y un gran número de muertes al año. En los últimos años, se ha publicado la detección de cepas de Salmonella resistente a diferentes antimicrobianos a partir de muestras obtenidas de fauna salvaje. Se ha demostrado la capacidad de la fauna silvestre como portadora asintomática de dicha bacteria, lo cual cobra especial importancia en el caso de las aves...
Salmonella is one of the most important foodborne pathogens in the European Union. It causes the highest number of outbreaks, and is the second pathogen with the greatest number of cases, only behind Campylobacter. Despite being a commensal bacterium of the intestine of numerous homoeothermic species, it can cause gastrointestinal or even extra-intestinal clinical signs, like reactive arthritis or meningitis. Furthermore, Salmonella resistant strains have already been isolated in both humans and animals to many different antimicrobials. This condition can affect the effectiveness of treatment, aggravating clinical presentations. Currently, antimicrobial resistance represents the greatest challenge for 21st-century medicine, as it causes treatment failure in thousands of cases and a large number of deaths per year. During last years, numerous resistant Salmonella strains to different antimicrobials has been detected from samples obtained from wildlife and environment. The ability of wildlife as an asymptomatic carrier of this bacterium has been demonstrated, which is especially important in the case of birds...
