The renal bacterial colonization has not been explored so far.
The aim of this study was to describe the renal microbiome and to determine differences of the renal microbiome in healthy and tumor-bearing parenchyma.
Ten biopsies from patients undergoing laparoscopic nephrectomy for renal carcinoma with no history of urinary tract infections within the last 6 months were included in this study. The identification of all microorganisms was done using 16S DNA sequencing. The beta diversity analysis was performed by Bray-Curtis dissimilarity.
In all kidney samples, a plethora of microorganisms was found, with significant differences between benign and malignant renal tissue (p < 0.0001).
There is evidence that healthy kidney tissue as well as renal cell cancer tissue have a specific microbiome, thus opening new perspectives in renal physiology and tumor pathogenesis.
