Fig. 5: Altered gut fungal taxa are strongly linked with gut bacterial taxa and blood inflammatory, liver, infectious and metabolic biomarkers.

Spearman correlations of significantly altered gut mycobiota with significantly altered gut microbiota in (A) COVID-19 patients or (B) H1N1-infected patients. Spearman correlations of significantly altered gut mycobiota with significantly altered blood biomarkers in (C) COVID-19 patients or (D) H1N1-infected patients. Only correlations with a P < 0.05 and a correlation coefficient >0.4 or <−0.4 are shown.
