An unusual case report of a patient with bacteremia due to Succinivibrio dextrinosolvens is presented. Heretofore, Succinivibrio spp. were thought to occur only as organisms in the rumens of herbivorous animals. Succinivibrio is an anaerobic, Gram-negative, curved, spiral bacillus with a polar monotrichous flagellar pattern. Volatile acids produced from glucose metabolism include succinic, acetic, formic and lactic. Various carbohydrate substrates are fermented to produce strong or weak acid end-points. Succinivibrio spp. will grow in bile, will not hydrolyze esculin or starch, and do not produce indol, catalase, lecithinase, lipase, or hemolysis. Bacteremia in this case was thought to have been the result of hypotension in the course of severe gastrointestinal hemorrhage. This is thought to represent the first published case of human infection due to Succinivibrio spp.
本文报告了一例罕见的由解右旋糖琥珀酸弧菌引起菌血症的病例。在此之前，琥珀酸弧菌属仅被认为是草食动物瘤胃中的微生物。琥珀酸弧菌是一种厌氧、革兰氏阴性、弯曲的螺旋杆菌，具有极生单鞭毛模式。葡萄糖代谢产生的挥发性酸包括琥珀酸、乙酸、甲酸和乳酸。各种碳水化合物底物被发酵产生强或弱酸终点。琥珀酸弧菌属能在胆汁中生长，不水解七叶苷或淀粉，不产生吲哚、过氧化氢酶、卵磷脂酶、脂肪酶或溶血。该病例中的菌血症被认为是严重胃肠道出血过程中低血压的结果。这被认为是首例关于琥珀酸弧菌属引起人类感染的报道病例。
