Sponsor's own description

The research will focus on the possible connection between prostate cancer, and various species of bacteria in the large intestine. In consecutive patients, referred to prostate biopsies, rectal swabs will be taken before the biopsies and before antibiotic treatment. The gut flora will be examined and characterized by a microbiome analysis tool. Negative patients will serve as internal control. The investigators will look for association between prostate cancer of various grades and the presence of specific enteropathogens in the rectal flora of the participants.
