A 72-year-old man, having had an artificial valve for almost 20 years now, presented with tiredness that had persisted for several weeks and reported weight loss of 5 kg. In more recent days he experienced fever and cold shivers, and an associated dry cough. Bearing in mind the potential for endocarditis, blood cultures were grown. In this, we identified a small, Gram-negative rod with a small, smooth, raised colony that grew slowly. We considered a micro-organism from the 'HACEK group', which is a group of micro-organisms including Haemophilus aphrophilus, Haemophilus paraphrophilus, Cardiobacterium hominis, Eikenella corrodens, Kingella kingae and Aggregatibacter (formerly: Actinobacillus) actinomycetemcomitans. More careful observation revealed that the bacteria formed star-shaped colonies, proving that A. actinomycetemcomitans was the cause of this non-acute endocarditis. The patient received antibiotic treatment. Because non-acute endocarditis is often caused by hidden abnormalities in the mouth or teeth and A. actinomycetemcomitans plays an important role in severe cases of peridontitis, a dental surgeon was consulted. The dental surgeon diagnosed multifocal peridontitis and treated the patient, who was able to leave the hospital after 6 weeks of antibiotic treatment.
