Aggregatibacter paraphrophilus (former name Haemophilus paraphrophilus) is a normal commensal of the oral flora. It is a rare cause of hepatobiliary or intracerebral abscesses.
We report a case of a 53-year-old Caucasian man with a liver abscess and subsequent brain abscesses caused by Aggregatibacter paraphrophilus. The probable source of the infection was the oral flora of our patient following ingestion of a dental filling. The presence of a large patent foramen ovale was a predisposing factor for multifocal abscesses.
In this case report, we describe an unusual case of a patient with both liver and brain abscesses caused by an oral commensal Aggregatibacter paraphrophilus that can occasionally show significant pathogenic potential.
副嗜沫聚集杆菌（曾用名副嗜沫嗜血杆菌）是口腔菌群的正常共生菌。它是肝胆或脑脓肿的罕见病因。
我们报告一例53岁的白种男性病例，其肝脏脓肿及随后的脑脓肿由副嗜沫聚集杆菌引起。感染的可能来源是患者在摄入一颗补牙材料后口腔中的菌群。存在较大的卵圆孔未闭是发生多灶性脓肿的一个易感因素。
在本病例报告中，我们描述了一例不寻常的病例，患者同时患有肝脏和脑脓肿，病因是一种口腔共生菌副嗜沫聚集杆菌，该菌偶尔可表现出显著的致病潜能。
