Our objectives in this study were to elucidate various aspects of the epidemiology of Staphylococcus saprophyticus. This organism was isolated from the midstream urine specimens of 7.5% of 145 college women with frequency and urgency of urination and dysuria, but from only 0.07% of 14,835 urine specimens from adult inpatients at the Victoria General Hospital. It was found to be part of the urethral flora of only 2% of healthy women. Other staphylococci which formed part of the urethral flora of 100 healthy women included S. epidermidis (59 women), S. hominis (15 women), S. haemolyticus (13 women), S. warneri (9 women), and S. aureus (6 women). Finally, we determined that resistance to the 5-micrograms novobiocin disk has a 93% positive predictive accuracy as a presumptive test for S. saprophyticus.
我们开展这项研究的目的是阐明腐生葡萄球菌流行病学的各个方面。该菌从145名有尿频、尿急和排尿困难症状的大学女生的中段尿标本中分离出来，分离率为7.5%，但在维多利亚总医院14835份成年住院患者的尿标本中，分离率仅为0.07%。研究发现，它仅在2%的健康女性尿道菌群中存在。在100名健康女性的尿道菌群中发现的其他葡萄球菌包括表皮葡萄球菌（59名女性）、人葡萄球菌（15名女性）、溶血葡萄球菌（13名女性）、沃氏葡萄球菌（9名女性）和金黄色葡萄球菌（6名女性）。最后，我们确定，对5微克新生霉素纸片耐药作为腐生葡萄球菌的初步检测，其阳性预测准确率为93%。
