Experimental prostatitis in female Mastomys natalensis--a preliminary report.

Female Mastomys natalensis were inoculated with a suspension of Klebsiella pneumoniae into the bladder. All animals developed prostatitis without urinary tract infection between the 9th and the 12th day after inoculation. 10(4) - 10(5) CFU of K. pneumoniae per gram prostatic tissue could be cultivated. Histologically acute purulent prostatitis was detected in most cases 6 days after infection. In the follow-up periacinar infiltration predominated.
