Staphylococcus saprophyticus as a urinary pathogen: a six year prospective survey.
British Medical Journal (Clinical Research Ed.)
|October 26, 1985
Summary
Staphylococcus saprophyticus increasingly caused urinary tract infections in young women over six years. These infections displayed seasonality, and the bacteria remained sensitive to common antibiotics.
Area of Science:
- Microbiology
- Epidemiology
- Infectious Diseases
Background:
- Urinary tract infections (UTIs) are common in women.
- The causative agents of UTIs can vary.
- Staphylococcus saprophyticus is a known uropathogen.
Purpose of the Study:
- To analyze the incidence and trends of Staphylococcus saprophyticus causing UTIs in young women.
- To investigate the seasonality of S. saprophyticus infections.
- To assess the antimicrobial susceptibility of S. saprophyticus.
Main Methods:
- Prospective collection of weekly laboratory records.
- Analysis of UTI-causing organisms in women aged 15-25 over a six-year period (1978-1983).
- Identification and susceptibility testing of bacterial isolates.
Main Results:
- Staphylococcus saprophyticus caused an increasing proportion of UTIs in young women during the study period.
- S. saprophyticus-associated UTIs exhibited noticeable seasonality.
- All but four S. saprophyticus isolates were sensitive to commonly used antimicrobial agents.
Conclusions:
- Staphylococcus saprophyticus is a significant and growing cause of UTIs in young women.
- The sensitivity of S. saprophyticus to antibiotics may be linked to its limited commensal presence.
- Differentiating S. saprophyticus from other coagulase-negative staphylococci is clinically important.
