Antimicrobial activity of a selection of organic acids, their salts and essential oils against swine enteropathogenic bacteria
Abstract Background Accurate screening of new alternative antimicrobial compounds is essential for their use to control pathogens in swine production due to the replacement of antibiotics and zinc oxide. Most in vitro studies have separately reported the antimicrobial activity of organic acids and e...
