Epidemiological data from Western Australia regarding Staphylococcus saprophyticus urinary tract infections (UTIs) was collected over a 12 month period. Eighty-four percent of S. saprophyticus UTIs occurred in females 13-40 years of age and S. saprophyticus was the second most frequent cause of UTIs in this age group (15.2%) after Escherichia coli (70.8%). Although the monthly incidence fluctuated, no seasonality of S. saprophyticus UTIs could be demonstrated. The proportion of S. saprophyticus UTIs in pregnant women (6.5%) compared with non-pregnant women (15.2%) appeared reduced, however, this reduction was not statistically significant. Finally, while S. saprophyticus was isolated at a frequency of 4.6% from the genital tract of females aged 13-40 years, it could not be isolated from the genital tract of females aged > 40 years, nor from the genital tract of males aged 13-40 years, suggesting a possible reservoir of infection. These data imply a relationship between female hormonal status and S. saprophyticus UTIs which requires further investigation.
在西澳大利亚，我们收集了为期12个月的关于腐生葡萄球菌尿路感染（UTIs）的流行病学数据。84%的腐生葡萄球菌尿路感染发生在13至40岁的女性中，在这个年龄组中，腐生葡萄球菌是仅次于大肠杆菌（70.8%）的第二常见尿路感染病因（15.2%）。尽管月发病率有波动，但未发现腐生葡萄球菌尿路感染有季节性。与非孕妇（15.2%）相比，孕妇中腐生葡萄球菌尿路感染的比例（6.5%）似乎有所降低，然而，这种降低没有统计学意义。最后，虽然在13至40岁女性的生殖道中腐生葡萄球菌的分离频率为4.6%，但在40岁以上女性的生殖道中以及13至40岁男性的生殖道中均未分离到，这表明可能存在感染源。这些数据表明女性激素状态与腐生葡萄球菌尿路感染之间存在关联，这需要进一步研究。
