Stomach tumours

Caption

When Streptococcus anginosus infection occurred at stomach tumours implanted under mice skin, the bacteria spurred the growth of the gastric cancer cells, doubling the size and weight of tumours in some cases (middle row), compared to tumours without S. anginosus infection (top row). When a specific surface protein of the bacteria was genetically removed, the bacteria’s ability to encourage tumour growth was impaired (bottom row). (Credit: CUHK)
