铁( Fe)是生物有机体的必需营养素，病原菌从宿主体内获取生长、繁殖必需的Fe是其侵染宿主的前提。本文总结了宿主和肠道病原菌的Fe摄取方式及竞争机制，阐述了Fe对肠道微生物的影响，旨在为仔猪生产合理补Fe提供新依据。
철( Fe)시생물유궤체적필수영양소，병원균종숙주체내획취생장、번식필수적Fe시기침염숙주적전제。본문총결료숙주화장도병원균적Fe섭취방식급경쟁궤제，천술료Fe대장도미생물적영향，지재위자저생산합리보Fe제공신의거。
Iron ( Fe) is a vital nutrient for all living organisms. Bacterial pathogens must acquire Fe from host for growth and proliferation, which is the preconditon of bacteria infection. This review summarizes Fe uptake pathways and competitive mechanism of host and intestinal tract bacteria, and discusses the effects of Fe on the intestinal tract microflora, which will provide new references for Fe supplement in piglet production.
