Streptobacillus moniliformis is a pleomorphic, fastidious gram-negative bacillus that colonizes rodent respiratory tracts and causes rat-bite fever in humans. Rat-bite fever is associated with septic arthritis, usually monoarticular or pauciarticular. We report a rare case of polyarticular septic arthritis caused by S. moniliformis; the disease was initially misdiagnosed as inflammatory arthritis.
念珠状链杆菌是一种多形性、苛刻的革兰氏阴性杆菌，定植于啮齿动物的呼吸道，并导致人类的鼠咬热。鼠咬热与脓毒性关节炎有关，通常为单关节炎或少关节炎。我们报告了一例由念珠状链杆菌引起的罕见多关节炎性脓毒性关节炎；该疾病最初被误诊为炎症性关节炎。
