[Effect of interferon type I on the in vivo persistence of Salmonella typhimurium].

The influence of type I interferon on the persistence of S. typhimurium in the body of mice has been studied. The injection of the preparation of interferon has been shown to be conductive to the survival of the animals and to reduce the time of Salmonella persistence in the body. The injection of interferon enhances the phagocytic activity of macrophages in the peritoneal exudate of mice.
