Background & Aim: Microbiota is a collection of microorganisms that live in the oral cavity, respiratory system and intestine of multicellular organisms. Microbiota exerts numerous physiological and pathological effects on the host in which it lives. Increasing attention has been directed to the interaction of host and microbiota. Adenomatous polyps are one of the common symptoms of colon cancer, the second leading cause of cancer-related death worldwide. Our study tries to show the relationship between Lactobacillus, Bifidobacterium, Enterococcus faecalis and Fusobacterium nucleatum in the intestinal paraffin tissue samples of adenomatous polyp patients and healthy individuals.
Materials & methods: In this study, in order to investigate the mentioned bacteria in a total of 100 samples of intestinal paraffin tissue from adenomatous polyp patients (50 people) and healthy controls (50 people) for the presence, copy number and relative quantity of the above bacterial species using Real-time polymerase chain reaction (PCR), compared to the reference gene, were investigated.
Results: In the studied samples, the presence and number of copies of Enterococcus faecalis bacteria in adenomatous polyp samples was significantly higher than the other three groups. There was no significant difference in the abundance and presence of Fusobacterium nucleatum and Lactobacillus species between the two groups. Also, a decrease in the average number of gaps and the relative abundance of Bifidobacterium species in adenomatous polyps compared to the control group was obtained.
Conclusion: Our study showed a higher number of Enterococcus faecalis bacteria and a decrease in the number of Bifidobacterium species in the samples of intestinal paraffin tissue of patients with adenomatous polyps compared to the control group. However, any association between gut microbiome dysbiosis and adenomatous polyps remains unknown.
