Methicillin-resistant Staphylococcus aureus prostatitis.

Prostatitis is a common condition that is associated with a poor quality of life. A recent National Institutes of Health Consensus Panel classified prostatitis into the categories of acute bacterial, chronic bacterial, chronic nonbacterial, and asymptomatic. Bacterial prostatitis is usually caused by Escherichia coli and other gram-negative bacteria, but it is not frequently caused by Staphylococcus aureus. Community-acquired methicillin-resistant S. aureus infections are increasing. Moreover, 2 cases of methicillin-resistant S. aureus prostatic abscesses have been reported. We describe what we believe to be the first case of a patient with community-acquired methicillin-resistant S. aureus acute prostatitis as determined by cultures of prostatic tissue, blood, and nares.
