A modified glucomannan mycotoxin-adsorbing agent counteracts the reduced weight gain and diminishes cecal colonization of Salmonella Typhimurium in T-2 toxin exposed pigs.


PMID 22835700

Abstract

The aim of the study was to investigate the effect of a modified glucomannan binder on the course of a Salmonella Typhimurium infection in pigs. Therefore, four pig diets were provided during 23 days: (1) free of mycotoxins, (2) containing 1g binder per kg feed, (3) containing 83 μg T-2 toxin per kg feed and (4) containing 83 μg T-2 toxin and 1g binder per kg feed. After 18 days, all pigs were inoculated with Salmonella Typhimurium and euthanized five days later. The addition of the binder to T-2 toxin contaminated feed counteracted the reduced weight gain of pigs caused by T-2 toxin and reduced the amount of Salmonella Typhimurium in the cecum and cecal contents. In vitro findings might indicate that the binder captures Salmonella. We thus conclude that the binder counteracts T-2 toxin induced weight loss and possibly binds Salmonella, resulting in a reduced cecal colonization.
