Tóm tắt

In Southern blot analysis using Mycoplasma16S ribosomal DNA (rDNA) as a probe, positive signals were detected in DNA samples from surgical specimens of gastric cancers. The DNA that hybridized to Mycoplasma 16S rDNA was eluted from the gel, cloned and sequenced. The cloned sequence was identical to 16S rDNA of Streptococcus anginosus. In Southern blot analysis with the S. anginosus 16S rDNA fragment as a new probe, positive signals were detected in 9 (20%) out of 43 cases of gastric cancer.
