Figure Lengend Snippet: Citrulline eliminated cecal C. difficile in ABX+HGM hamsters. ( A–D ) Cecal contents in ABX + HGM hamsters were collected on days 3 and 20 post-infection. The fecal microbiota of a human donor was included for reference. CosmosID performed the sample processing and sequencing. A newer CosmosID common kingdom 1.0.0 analysis workflow was used for analysis. ( A–B ) Alpha and beta diversities of cecal microbiota. n = 4 ABX + HGM hamsters per group. ( C ) A heatmap of the relative abundance of cecal bacteria. The relative abundance of C. difficile was too low to be shown in the top 20 bacteria list. n = 4 ABX + HGM hamsters per group. ( D ) Relative cecal C. difficile abundance. Citrulline treatment eliminated cecal C. difficile in infected hamsters on day 3 and vancomycin-treated infected hamsters on day 20. A low cecal level of C. difficile was found in vancomycin-treated infected hamsters on day 20. C, citrulline; V, vancomycin. Mean ± SD. n = 4 ABX + HGM hamsters per group. All statistical tests were calculated by CosmosID.
Article Snippet: After 2 hours, the cells were lysed for phosphorylated heat shock protein 27 (pHSP27) ELISA (DY2314) or phosphorylated glycogen synthase kinase 3 alpha/beta (pGSK3α/β) ELISA (DYC2630) from R&D Systems.
