Seventy-seven clinical isolates of Xanthomonas maltophilia (Stenotrophomonas maltophilia) were consecutively collected from the Rigshospitalet, Copenhagen, ribotyped and compared with the ribotypes of 25 other clinical and reference strains of Xanthomonas maltophilia. Using restriction enzyme EcoRI, 20 different ribotypes were observed, with 78 isolates displaying the five most common types. Using another enzyme, BamHI, these 78 isolates were further subdivided into 16 different ribotypes. Three patients harboured two strains with different ribotypes. No type was found related to only one department and no single-strain outbreak was detected. The origin of this wealth of different strains in hospital patients needs to be established.
从哥本哈根里格霍斯医院连续收集了77株嗜麦芽窄食单胞菌（嗜麦芽寡养单胞菌）临床分离株，进行核糖分型，并与另外25株嗜麦芽窄食单胞菌临床和参考菌株的核糖型进行比较。使用限制性内切酶EcoRI，观察到20种不同的核糖型，78株分离株呈现出5种最常见的类型。使用另一种酶BamHI，这78株分离株进一步细分为16种不同的核糖型。3名患者携带两种具有不同核糖型的菌株。未发现某一类型仅与一个科室相关，也未检测到单菌株暴发。医院患者中如此丰富多样的菌株来源有待确定。
