Fig. 2From: Comparison of endotracheal aspirate and bronchoalveolar lavage fluid metagenomic next-generation sequencing in severe pneumonia: a nested, matched case–control studyDifferent microbiome in the ETA group and BALF group. A Comparison of species accumulation curves for the total microorganism, bacteria, fungus and virus between the ETA group (red lines) and BALF group (blue lines). B Distribution of different types of microbial etiology. C Spectra of potential pathogens in the ETA group and BALF group. Blue error line (across the grid lines) in the middle panels indicate that pathogens were not significantly different between the two groups (P > 0.05). Abbreviations: ETA, endotracheal aspirates; BALF, bronchoalveolar lavage fluid; CMV, Cytomegalovirus; EBV, Epstein-Barr virus; HSV-1, Herpes simplex virus type 1; HAdV, Human adenovirus; WUV, WU polyoma virusBack to article page
