Review of CRISPR-Cas Systems in Species: Current Knowledge and Perspectives.

spp. are pathogens widely distributed in the environment and is associated with food-borne illness in humans. Food facilities represent an adverse environment for this bacterium, mainly due to the disinfection and cleaning processes included in good hygiene practices, and its virulence is related to stress responses.

bactericidal activity of a carbohydrate polymer with zinc oxide for the treatment of chronic wounds.

Biological adhesives and effective topical therapeutic agents that improve wound healing are urgently required for the treatment of chronic ulcers. A biodegradable adhesive based on a carbohydrate polymer with zinc oxide (CPZO) was shown to possess anti-inflammatory activity and enhance wound healing, but its bactericidal activity was unknown. To investigate the bactericidal activity of CPZO against bacteria commonly present as infectious agents in chronic wounds.

Association of Listeria monocytogenes LIPI-1 and LIPI-3 marker llsX with invasiveness.

Listeria monocytogenes is an opportunistic pathogen that is widely distributed in the environment. The evolution of its genome has exhibited differences in virulence among strains of the same species. Listeria monocytogenes LIPI-3 (Listeria Pathogenicity Island 3) and LIPI-1 (Listeria Pathogenicity Island 1) are considered responsible for the increased virulence in some strains.
