The dominant genus Rosenbergiella in the AP group was positively correlated with CRP (r = 0.23, p = 0.02), IL-6 (r = 0.27, p = 0.01), PCT (r = 0.24, p = 0.02), BISAP score (r = 0.22, p = 0.03) and Sofa score (r = 0.23, p = 0.02). This evidence concerns the gene CRP and alkaline phosphatase measurement.
