Listeria monocytogenes will be introduced by Dr Javier Pizzaro Cerda from Pasteur Institute

Javier Pizarro Cerda bdDr Javier Pizarro Cerda, from Pasteur Institute will share his research about 'Modulation of Host Microbiota by Listeria monocytogenes' during the 3rd World Congress on Targeting Microbiota, held in Pasteur Institute (Paris, France).


According to him, "listeria monocytogenes is a foodborne bacterial pathogen which can induce gastroenteritis, abortions in pregnant women and meningitis in the new born. Epidemic Listeria monocytogenes strains are characterized by the presence of a pathogenicity island coding for the toxic peptide listeriolysin S (Lls). Lls has been previously described as a virulence factor required for bacterial survival within animal hosts; our recent work demonstrates that Lls is the first described Listeria monocytogenes bacteriocin which modulates the host intestinal microbiota, favoring bacterial colonization of the intestine and allowing bacterial dispersal to other host organs".
