Relative abundance of species at the classification level of Genus in the ALL group. A total of 99 genera were found at the classification level of genus. Among the 99 genera of bacteria in the ALL group, Enterococcus was the predominant genus (39.34%, in purple), Bacteroides was 20% in brown, Unclassified was 7.33% in shallow orange, Streptococcus was 6.51% in shallow red, Faecalibacterium was 5.14% in red, and so on. Among these genera, the dominant species in ALL patients and healthy controls showed significant differences, a total of 12 species including Acinetobacter, Actinomyces, Bosea, Brevundimonas, Enterococcus, Megasphaera, Oribacterium, Rhizobium, Ruminiclostridium, Sphingomonas, Tyzzerella and Veillonella were more abundant than in the control group
