Staphylococcus saprophyticus in males with symptoms of chronic prostatitis.

Staphylococcus saprophyticus was isolated in 17 percent (12 of 71 men) during one year, but with a peak in August and September to 21 percent in patients referred to the urology department with a suspicion of chronic bacterial prostatitis. Seven of the 12 men had S. saprophyticus in highest number at the prostatic level. Three of these were designated as chronic bacterial prostatitis. In this study the occurrence of S. saprophyticus appears to follow, and possibly depends on, previous antibiotic therapy. S. saprophyticus disappeared without treatment in all cases.
