Comparative analysis of the bacterial population of the prostate in its cancer and benign hyperplasia
A bacteriological study of prostate biopsy specimens was conducted in patients with prostate benign hyperplasia (PBH) and in those with prostate cancer (PC). It revealed a wide range of aerobic (Corynebacterium sp., Enterococcus sp., E. coli, S. haemolyticus, S. hominis) and nonclostridial anaerobic (Bacteroides sp., Bifidobacterium sp., Eubacterium sp., Propionibacterium sp., Рeptococcus niger, Peptostreptococcus sp., Prevotella sp., Veilonella sp., Fusobacterium sp., Capnocytophaga ochracea, Streptococcus parvulus) bacteria. Differences were seen in the detection rate of these microorganisms and in the level of tissue infectivity in PBH and PC. The average seeding of the prostate biopsy specimens and the detection rate of different types of bacteria in PBH were greater than those in PC; moreover, some bacteria were undetectable in PC at all.
