Among 15 strains of Staphylococcus saprophyticus of various origin, 13 presented different plasmid patterns, making plasmid identification a useful epidemiological marker. In a consecutive study of 14 young female patients with urinary tract infection caused by S. saprophyticus, 6 patients were simultaneously positive for the same bacterium in the stools. Three paired samples contained the identical plasmid-identified clone of S. saprophyticus indicating that the rectum may be a reservoir of this urinary pathogen.
在15株来源各异的腐生葡萄球菌中，13株呈现出不同的质粒图谱，这使得质粒鉴定成为一种有用的流行病学标记。在一项对14例由腐生葡萄球菌引起的年轻女性尿路感染患者的连续研究中，6例患者的粪便中同时检测到相同细菌呈阳性。3对样本含有经质粒鉴定的相同腐生葡萄球菌克隆，这表明直肠可能是这种泌尿道病原体的储存库。
