Many clinical laboratories have difficulty in identifying a group of organisms which are catalase negative, oxidase positive, Gram negative rods. We describe a case of purulent sacroiliitis due to Haemophilus paraphrophilus where the organism was initially misidentified as Eikenella corrodens leading to inappropriate antimicrobial chemotherapy. We review the strains of H. paraphrophilus and E. corrodens that were identified by the National Collection of Type Cultures over the last ten years. Only 21 of 100 strains identified as E. corrodens were submitted as E. corrodens. Seven strains submitted as possible E. corrodens were identified as H. paraphrophilus. Several different species of Gram negative rods may produce pitting on agar and this seems to be poorly recognised. However, further tests are available to facilitate correct identification of these strains.
许多临床实验室在鉴定一组过氧化氢酶阴性、氧化酶阳性、革兰氏阴性杆菌的微生物时存在困难。我们描述了一例由副嗜沫嗜血杆菌引起的化脓性骶髂关节炎病例，该微生物最初被误诊为腐蚀艾肯菌，导致了不恰当的抗菌化疗。我们回顾了过去十年中由国家典型培养物保藏中心鉴定的副嗜沫嗜血杆菌和腐蚀艾肯菌菌株。在100株被鉴定为腐蚀艾肯菌的菌株中，只有21株被提交为腐蚀艾肯菌。7株被提交为可能的腐蚀艾肯菌的菌株被鉴定为副嗜沫嗜血杆菌。几种不同种类的革兰氏阴性杆菌可能会在琼脂上产生蚀斑，而这似乎未得到充分认识。然而，可以进行进一步的检测以促进对这些菌株的正确鉴定。
