Infection with Yersinia enterocolitica had been associated with acute appendicitis in approximately six per cent of patients in northern European countries. However, the incidence of Y. enterocolitica in patients with appendicitis in this country is uncertain. Therefore, this study was undertaken to ascertain whether Y. enterocolitica is a possible infectious agent in appendicitis in the southwestern United States. Fifty prospective patients (35 men and 15 women) with an average age of 22.3 years (range 3 to 62 years) underwent appendectomy for presumed appendicitis. Portions of each specimen were cultured for Y. enterocolitica with highly selective media (Cefsulodin-Irgasan-Novobiocin [CIN] agar). Pathologically, 44 of the patients had appendicitis and 6 patients had normal appendices. Four of the 44 patients (9.1%) with appendicitis were found to be culture positive for Y. enterocolitica, while it was recovered from none of the normal appendices. This indicates that Y. enterocolitica may represent the major pathogen in acute appendicitis in a small, but distinct, portion of indigent patients within Los Angeles County as it does elsewhere in the world.
在北欧国家，约6%的患者中，小肠结肠炎耶尔森菌感染与急性阑尾炎有关。然而，该国阑尾炎患者中小肠结肠炎耶尔森菌的发病率尚不确定。因此，开展本研究以确定小肠结肠炎耶尔森菌是否是美国西南部阑尾炎的一种可能感染源。五十名预期患者（35名男性和15名女性），平均年龄22.3岁（范围3至62岁），因疑似阑尾炎接受阑尾切除术。每个标本的部分用高选择性培养基（头孢磺啶-伊红-新生霉素[CIN]琼脂）培养小肠结肠炎耶尔森菌。病理检查显示，44例患者患有阑尾炎，6例患者阑尾正常。44例阑尾炎患者中有4例（9.1%）小肠结肠炎耶尔森菌培养呈阳性，而正常阑尾中均未检出该菌。这表明，与世界其他地方一样，小肠结肠炎耶尔森菌可能是洛杉矶县一小部分但独特的贫困患者急性阑尾炎的主要病原体。
