Analysis of microbial diversity in control and diabetic groups using 16 S rDNA sequencing. (A) Dilution curve showing the reasonableness of the sample size with the increase of sample size. The x axis represents the number of sequencing samples randomly selected from a certain sample, and the y axis represents the number of OTUs that can be constructed based on this number of sequencing samples to reflect the depth of sequencing. (B) Rank abundance curve showing the abundance and evenness of conjunctival flora in the WT-TC and DB-TC groups. (C) Alpha diversity indices including Pielou, Shannon, and Simpson indices, reflecting the abundance and diversity of microbial communities in the samples. The overall index of the WT-TC group was higher than that of the DB-TC group, indicating a higher degree of microbial community diversity in the control group. The occurrence of diabetes caused a decrease in species richness and diversity (p < 0.05). The goods_coverage index for each group was greater than 0.99, indicating high credibility of the data
