There were no differences in

the prevalence of adenovirus,

herpesvirus, papillomavirus, polyoma

virus and C. albicans DNA.

Most prostatectomies (87%)

contain bacterial DNA from

one or more species. The

majority of individual tissue

core samples were negative,

suggesting regional heterogeneity

in the presence of bacteria

and a lack of a generalized

or ubiquitous prostatic flora.

BKV was frequently detected

and could play a relevant role

in the development and

progression of human PC,

whereas HPV does not seem

to be implicated in this type of

human neoplasia.

The prostate is a complex

habitat where mixed

infections with oncogenic

DNA viruses frequently

occur and opens the

discussion to the

potential role of these

viruses in the PC.

HPV frequency was

significantly higher in PC

cases than in controls;

this finding suggests

their participation in

PC develpment or tumor progression.
