AIM: To investigate the impact of minor abdominal surgery on the caecal microbial population and on markers of gut ***: Four week old piglets were randomly allocated to a no-surgery "control" group(n = 6) or a "transection surgery" group(n = 5).During the transection surgery procedure, a conventional midline incision of the lower abdominal wall was made and the small intestine was transected at a site 225 cm proximal to the ileocaecal valve, a 2 cm segment was removed and the intestine was *** received a polymeric infant formula diet throughout the study period and were sacrificed at two weeks *** outcomes including weight, stool consistency and presence of stool fat globules were *** throughput DNA sequencing of colonic content was used to detect surgery-relateddisturbances in microbial composition at phylum, family and genus *** and richness estimates were calculated for the control and minor surgery *** disturbances in the gut microbial community are linked to inflammation we compared the gene expression of key inflammatory cytokines(TNF, IL1 B, IL18, IL12, IL8, IL6 and IL10) in ileum, terminal ileum and colon mucosal extracts obtained from control and abdominal surgery groups at two weeks ***: Changes in the relative abundance of bacterial species at family and genus level were confined to bacterial members of the Proteobacteria and Bacteroidetes *** level compositional shifts included a reduction in the relative abundance of Enterobacteriaceae(22.95 ± 5.27 vs 2.07 ± 0.72, P < 0.01), Bacteroidaceae(2.54 ± 0.56 vs 0.86 ± 0.43, P < 0.05) and Rhodospirillaceae(0.40 ± 0.14 vs 0.00 ± 0.00, P < 0.05) following transection ***, at the genus level, changes associated with transection surgery were restricted to members of the Proteobacteria and Bacteroidetes phyla and included decreased relative abundance of Enterobacteriaceae(29.20 ± 6.74 vs 2.88 ±
