Principal coordinate analysis (PCoA) of microbial communities among PT and PM treatment groups and AF control group. (A) Distribution of all samples on d3; (B) Distribution of all samples on d7. Samples that are positioned close to each other are similar to each other in microbial compositions whereas samples that are positioned distantly from each other are distinct to each other in microbial compositions. AF, antibiotic free group; PT, piperacillin-tazobactam group; PM, combination of penicillin and moxalactam group.
