Bacterial prostatitis caused by Staphylococcus saprophyticus
Abstract:
Staphylococcus saprophyticus has been shown to be an important uropathogen in urinary tract infections in young women. Thirty-five isolates from 27 patients with staphylococci in the prostatic fluid of men with bacterial prostatitis were evaluated for the presence of S. saprophyticus. Three patients (11 per cent) with this organism were identified by novobiocin resistance (disk diffusion test), absence of hemolysis, and coagulase. These patients tended to be younger, more symptomatic, and more responsive to appropriate antibiotic therapy than those with staphylococcus epidermidis. S. saprophyticus appears to be an important pathogen in prostatic infections.
Insights
Staphylococcus saprophyticus, a common cause of urinary tract infections in women, was found in 11% of men with bacterial prostatitis. This finding suggests S. saprophyticus may also be a significant pathogen in prostatic infections.
Area of Science:
- Microbiology
- Urology
- Infectious Diseases
Background:
- Staphylococcus saprophyticus is a known uropathogen causing urinary tract infections (UTIs) in young women.
- Bacterial prostatitis is an infection of the prostate gland in men, often caused by bacteria.
Purpose of the Study:
- To investigate the prevalence and characteristics of Staphylococcus saprophyticus in men with bacterial prostatitis.
- To compare clinical features and treatment response in patients with S. saprophyticus versus Staphylococcus epidermidis prostatitis.
Main Methods:
- Analysis of 35 staphylococcal isolates from prostatic fluid of 27 men with bacterial prostatitis.
- Identification of S. saprophyticus using novobiocin resistance, absence of hemolysis, and coagulase tests.
Main Results:
- Staphylococcus saprophyticus was identified in three patients (11%) with bacterial prostatitis.
- Patients with S. saprophyticus prostatitis were generally younger, more symptomatic, and responded better to antibiotics compared to those with S. epidermidis.
Conclusions:
- Staphylococcus saprophyticus is an important pathogen in prostatic infections, not just urinary tract infections.
- Further research is warranted to understand the role of S. saprophyticus in male lower urinary tract infections.
