Unravelling mechanisms by which Zinc influences diversity and resistance of porcine intestinal Escherichia coli populations

Currently, different strategies are used to reduce post-weaning diarrhea (PWD) associated with E. coli infections such as high-level dietary zinc oxide supplementation. However, effects of high-zinc diets on porcine intestinal bacterial populations are not fully understood yet. The aim of this work is to characterize a representative selection of E. coli isolates obtained from a high-zinc fed piglet group [HZG] and a regular fed control group [CG].
