The occurrence of Staphylococcus saprophyticus, Chlamydia trachomatis, and Neisseria gonorrhoeae in urethral specimens of 252 men attending a venereal disease clinic was studied. When using a selective broth medium containing novobiocin and nalidixic acid, Staph. saprophyticus was isolated from 20.8% of 178 men with symptoms of urethritis and from 14.9% of 74 men without such symptoms. Staph. s...

Treatment of uroepithelial cells with lipoteichoic acid from Staphylococcus saprophyticus resulted in a decrease in the adherence of this organism. Similar effects were observed when bacteria were pretreated with the lipoteichoic acid ligands albumin and anti-polyglycerophosphate monoclonal antibodies. Lipoteichoic acid might behave as an adhesin of S. saprophyticus.

The urease gene of Staphylococcus saprophyticus CCM883 was cloned and expressed in Staphylococcus carnosus TM300. In vitro translation of the cloned DNA sequences revealed six polypeptides (of 70, 47, 29, 27, 20, and 17 kilodaltons) that were associated with enzyme activity. Introduction of the cloned genes into a urease-negative mutant of S. saprophyticus restored the virulence of this strain,...

The epidemiology of urinary tract infections (UTI) by Staphylococcus saprophyticus has not been fully characterised and strain typing methods have not been validated for this agent. To evaluate whether epidemiological relationships exist between clusters of pulsed field gel-electrophoresis (PFGE) genotypes of S. saprophyticus from community-acquired UTI, a cross-sectional surveillance study was...

OBJECTIVE The purpose of this study was to determine whether colonization was persistent or recurrent in a small group of women who had repeated recovery of Staphylococcus saprophyticus from their urogenital tracts. METHODS Paired isolates of S. saprophyticus from each of the study subjects were genotypically typed by plasmid fingerprinting and comparison of chromosomal-DNA restriction fragme...

The use of a novobiocin-containing medium provided little benefit over observable quantitative growth on blood agar in detecting Staphylococcus saprophyticus in urine cultures.
