Altered composition of the gut mycobiota and microbiota in patients with COVID-19. A The log scale of viral copy number for each subject is illustrated by a red bar chart. Fungal and bacterial Shannon indices are presented as circles with three levels of colors (for fungal Shannon index: < 1, white; 1–2, light green; > 2, dark green; for the bacterial Shannon index: < 5, white; 5–6, light orange, > 6, orange) B The composition of major gut mycobiota in patients with severe or mild COVID-19 and healthy controls.
