Global view of temporal sRNA expression profiles in rabbit urine during T. gondii infection. a The sRNA correlation heatmap of sample clustering. b Principal component analysis of all identified urine sRNAs. c Unsupervised hierarchical clustering of sRNA profiling data. sRNA intensity is normalized so that blue represents low intensity and yellow represents high intensity. Columns were hierarchically clustered based on a complete linkage using Pearson correlation coefficients as the distance measure. Sample groups are acutely infected rabbits, chronically infected rabbits and uninfected control rabbits, which are labeled as AI, CI and Con, respectively
