gastric mucosa microbiota Raw sequence reads
Here, we characterized the gastric mucosa microbiome of 85 GC tumor tissues and matched non-tumor tissues using 16s rRNA gene sequencing, respectively. Microbial diversity and richness were higher in GC tumor tissues than in non-tumor tissues. The abundance of Helicobacter was increased in non-tumor tissues, while the abundance of Lactobacillus, Enterococcus, Prevotella, Bacteroides, Streptococcus, and 3 additional genera was increased in the tumor tissues.
