J Microbiol Immunol Infect 2015 Apr 25;48(2):226-8. Epub 2012 Sep 25.

Department of Internal Medicine, Teikyo University School of Medicine, 2-11-1 Kaga, Itabashi-ku, Tokyo 173-8606, Japan.

We report the case of using a long-term combination of meropenem and amikacin to treat infective endocarditis caused by Enterobacter cloacae resistant to third- and fourth-generation cephalosporins. Multi-drug resistant Gram-negative bacilli, such as the E. cloacae in our study, may become possible pathogens of infective endocarditis. Read More

Actinobacillus endocarditis associated with hypertrophic cardiomyopathy.

BMJ Case Rep 2012 Aug 13;2012. Epub 2012 Aug 13.

Department 2, Curry Cabral's Hospital, Lisbon, Portugal.

Infective endocarditis can be associated with complex clinical presentations, sometimes with a difficult multi-disciplinary management. Actinobacillus actinomycetemcomitans belongs to the Haemophilus species, Actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens and Kingella species group, responsible for 5% to 10% of infective endocarditis in native heart valves. These organisms have slow fastidious growth pattern, often associated with negative cultures, and cause systemic embolism with abscess formation. Read More

Department of Endocrinology, University Hospital South Manchester, Southmoor Road, Wythenshawe, Manchester M23 9LT, UK.

We present a case of aortic and tricuspid native valve endocarditis in which Cardiobacterium valvarum was isolated from the blood culture of a 65-year-old man. Cardiobacterium valvarum is a fastidious, Gram-negative bacillus. The genus Cardiobacterium encompasses two species - Cardiobacterium valvarum and Cardiobacterium hominis. Read More
