species are obligate anaerobic Gram-negative bacilli that are non-spore forming. The two most common species tied to human disease are and They are commensal organisms in the oropharynx, gastrointestinal tract, and genital tract of humans, but can cause invasive infections especially in the head and neck such as periodontal disease and Lemierre's syndrome. is an uncommon cause of infective endocarditis. We present a case of a previously healthy male who developed endocarditis with multiple sites of pyogenic abscess formation.
Even among anaerobes, which account for less than 1 % of infective endocarditis (IE) cases, is rare. Specific laboratory conditions are necessary for growth, leading to delays in diagnosis. Severe disease is common given its virulence and predisposition for thrombophlebitis. While uncommon, it is crucial to maintain a degree of suspicion for IE especially in individuals without prior cardiac disease whose infections were preceded by potential head and neck source.
该菌种为专性厌氧革兰氏阴性杆菌，不形成芽孢。与人类疾病相关的两种最常见菌种是[具体菌种1]和[具体菌种2]。它们是人类口咽、胃肠道和生殖道中的共生生物，但可引起侵袭性感染，尤其是在头颈部，如牙周病和勒米尔综合征。[具体菌种1]是感染性心内膜炎的罕见病因。我们报告一例既往健康男性发生[具体菌种1]心内膜炎并伴有多处化脓性脓肿形成的病例。
即使在占感染性心内膜炎（IE）病例不到1%的厌氧菌中，[具体菌种1]也很罕见。其生长需要特定的实验室条件，导致诊断延迟。鉴于其毒力和血栓性静脉炎倾向，严重疾病很常见。虽然不常见，但对于[具体菌种1]性心内膜炎保持一定程度的怀疑至关重要，尤其是在没有心脏病史且感染之前有潜在头颈部感染源的个体中。
