We report a case of synovitis in a 64-year-old man who developed the infection while on steroid therapy for rheumatoid arthritis. Dolosigranulum pigrum, a gram-positive catalase-negative coccus, was isolated from two sets of blood cultures prior to antibiotic therapy. The patient was treated with 4 weeks of appropriate antibiotics, and the synovial inflammation resolved. Although synovial aspirates were never positive for any bacteria or fungi, the timing of positive blood cultures and absence of other pathogens suggest the possible etiology as D. pigrum.
我们报告一例64岁男性滑膜炎病例，该患者在接受类风湿关节炎类固醇治疗期间发生感染。在抗生素治疗前，从两份血培养物中分离出革兰氏阳性、过氧化氢酶阴性的球形多尔氏菌。患者接受了4周的适当抗生素治疗，滑膜炎消退。尽管滑膜抽吸物从未检测出任何细菌或真菌呈阳性，但血培养阳性的时间以及不存在其他病原体表明可能的病因是球形多尔氏菌。
