摘要: Ileal colonisation resistance to Escherichia coli strain Bd 1107/75 08 (K88) in piglets aged 5, 26 and 47 days the possible relation indigenous gastric was studied. In diluted ileal extracts, heat labile growth inhibitory activity detected. At d, vitro adhesion of K88 fimbriae on E. mucus markedly increased, while level Lactobacillus crispatus 152 stomach tissue pieces decreased. addition, scanning electron microscopy revealed that composition squamous epithelium associated flora changed dramatically at this time. From these results, it appears age consequently related factors influence flora. Keywords: K88; Lactobacillus; Colonisation resistance; Adhesion; Growth.
