Diversity estimation of gut bacteria in rat feces. a Average number of usable raw reads (bars represent standard deviations); b Average number of OTUs at the 97% similarity level (bars represent standard deviations); c Rarefaction curves at the 97% similarity level. Each curve represents one biological sample; d Shannon–Wiener diversity index curves at the 97% similarity level. Each curve represents one biological sample
