A survey was undertaken about bacteriologic, epidemiologic and clinical features of infections caused by Yersinia. Yersinia enterocolitica and Yersinia pseudotuberculosis are gram negative rods of the enterobacteriaceae family. The number of cases of these infections has increased considerably in the past few years. Erythema nodosum often occurs after an enteritic infection by Yersinia. Other skin manifestations are erythema exsudativum multiforme, erythema figuratum and "drug-eruption-like exanthema". Moreover, Yersinia-arthritis may occur. In one particular case a Reiter-syndrome was described. The mechanism whereby Yersinia induce skin lesions is unknown. Prognosis is good. Therapy of choice for infections caused by Yersinia are tetracyclines.
针对耶尔森菌引起的感染的细菌学、流行病学及临床特征开展了一项调查。小肠结肠炎耶尔森菌和假结核耶尔森菌是肠杆菌科的革兰氏阴性杆菌。在过去几年中，这些感染的病例数显著增加。结节性红斑常发生于耶尔森菌肠道感染之后。其他皮肤表现有渗出性多形红斑、地图状红斑和“药疹样皮疹”。此外，可能会出现耶尔森菌关节炎。在一个特定病例中，描述了赖特综合征。耶尔森菌诱发皮肤病变的机制尚不清楚。预后良好。耶尔森菌感染的首选治疗药物是四环素。
