ABSTRACT Three novel bacterial strains, Staphylococcus epidermidis , Streptococcus salivarius , and Streptococcus anginosus , were cultured from human gastric biopsy tissue from Colombian, South America patients with a high risk for gastric cancer. Bacteria were sequenced using Illumina MiSeq technology for phylogenetic characterization and identification of genetic mechanisms conferring pathogenic or protective potential.
Mannion et al. (Thu,) studied this question.
