WebAug 5, 2024 · Figure 1 presents the pH changes in culture media containing co-cultures of LAB and S. saprophyticus BCRC 10786. The pH of the co-culture medium decreased over time. The pH of the PM68 co-culture over the first 4 h was the lowest (pH 4.19); this finding corresponds with the speculation that LAB inhibits the growth of pathogenic bacteria in … WebKilling of the strains by PMN was optimal between pHs 6.5 and 7.5 in urine at 485 mosM (being at least 90% of the control values in Hanks balanced salt solution), whereas at 200 mosM killing was reduced to 50 to 70% of these values. Reduced killing of all three strains occurred at pH 8, whereas at pH 6 only S. saprophyticus was killed.
Staphylococcus saprophyticus Mechanisms of Pathogenicity
The urine sediment of a patient with a S. saprophyticus urinary tract infection has a characteristic appearance under the microscope manifesting leukocytes, erythrocytes, and clumping due to cocci adhering to cellular elements. Chemical screening methods for bacteriuria, such as, urine nitrate and glucose do not always detect S. saprophyticus infection.
