Biofilm production by Salmonella spp. isolated from a poultry slaughterhouse.

摘要: Biofilms can be considered a virulence factor, once they protect the microorganisms involved in their matrix, increasing resistance to the action of antimicrobials and sanitizers, and allow their propagation in the environment. This association constitutes a form of protection to its development, fomenting symbiotic relations and allowing the survival in hostile environments. Biofilms can be produced on various surfaces such as food, food processing equipment, water and industrial piping, ventilation, medical devices and living tissue. Considering the importance of Salmonella in the productive chain of poultry, its pathogenic potential for infection in humans and the capacity of cross-transmission between foods, our aim was to evaluate the production of biofilms by 40 strains of Salmonella spp. isolated from two different types of mats (canvas and polystyrene), present in a poultry slaughterhouse, during 20 consecutive …
