Listeriosis is a zoonotic disease of food origin that can cause, both in the human species and in animals, symptoms of gastroenteritis, meningitis, bacteremia and miscarriages. The pathogen that causes this infection is the Listeria<\/em> bacteria. Juan Jos\u00e9 Quereda<\/a><\/strong><\/strong>, researcher with a Ram\u00f3n y Cajal contract and professor at the CEU Cardenal Herrera University (CEU UCH), where he leads the research group on Intracellular Pathogens<\/a><\/strong>, has been conducting research in this field since 2011. Professor Quereda has just published new advances, in collaboration with researchers from the Pasteur Institute in Paris, the University of Iowa and the CNB-CSIC in Madrid<\/strong>, on the mechanisms of transmission of this pathogen, its genetic characteristics, antibiotic resistance and its seasonal presence in dairy farms, which can contribute to designing more effective measures to curb its proliferation and develop new treatments against infection.<\/p>\n\n\n\n

Together with researchers from the Pasteur Institute in Paris and the University of Iowa, Professor Quereda <\/strong>has participated in the study of Listeriolysin S<\/strong>, a bacteriocin synthesized by this bacterium to facilitate intestinal colonization, altering the microbiota, and also promoting its expansion to other organs. In this study, led by Dr. Javier Pizarro Cerd\u00e1 and published in the journal Proceedings of the National Academy of Sciences (PNAS)<\/em>, they have found the mechanism of permeabilization of the bacterial membrane mediated by Listeriolysin S that facilitates its dissemination in the organism.<\/p>\n\n\n\n
