New species of the listeria genus discovered and baptised

It is estimated that only 1% of bacteria are pathogenic for humans or animals. Among them, the bacterial genus Listeria has been widely studied as it contains two species, Listeria monocytogenes and Listeria ivanovii, which are pathogenic, causing the disease known as listeriosis. Until now, the genus Listeria consisted of a total of 20 species. Researchers from the CEU Cardenal Herrera University of Valencia (CEU UCH) and the Institut Pasteur have expanded this list with the discovery of a new species: Listeria valentina, named for having been discovered in Valencia.
