| endocarditis with ruptured cerebral aneurysm caused by cardiobacterium valvarum sp. nov. | a fastidious gram-negative bacterium was isolated from the blood of a 37-year-old man who had insidious endocarditis with a sudden rupture of a cerebral aneurysm. characterization of the organism through phylogenetic and phenotypic analyses revealed a novel species of cardiobacterium, for which the name cardiobacterium valvarum sp. nov. is proposed. c. valvarum will supplement the current sole species cardiobacterium hominis, a known cause of endocarditis. surgeries and antibiotic treatment cure ... | 2004 | 15071009 |
| characterization of oral strains of cardiobacterium valvarum and emended description of the organism. | the description of the new species cardiobacterium valvarum prompted a search for additional strains of the organism. here we report characterization of four oral cardiobacterium strains from the culture collection of the university of goteborg. the 16s rrna gene sequences of the organisms exhibited 99.6% to 99.3% homology with cardiobacterium valvarum. the cellular fatty acid profiles, electrophoretic patterns of whole-cell proteins, growth rate and nutritional requirement, colonial and cellula ... | 2005 | 15872268 |

| the role of 16s rrna gene sequencing in identification of microorganisms misidentified by conventional methods. | traditional methods for microbial identification require the recognition of differences in morphology, growth, enzymatic activity, and metabolism to define genera and species. full and partial 16s rrna gene sequencing methods have emerged as useful tools for identifying phenotypically aberrant microorganisms. we report on three bacterial blood isolates from three different college of american pathologists-certified laboratories that were referred to arup laboratories for definitive identificatio ... | 2005 | 16333109 |
| endocarditis caused by cardiobacterium valvarum. | a fastidious, gram-negative bacterium was isolated from the blood of a 51-year-old man who had acute infectious endocarditis (ie). characterization of the organism through phenotypic and genotypic analyses revealed the causative role of cardiobacterium valvarum. this is the third reported case of ie caused by c. valvarum. | 2006 | 16455940 |
| fatal bioprosthetic aortic valve endocarditis due to cardiobacterium valvarum. | cardiobacterium valvarum was isolated from the blood of a 71-year-old man with fatal aortic valve endocarditis. the api nh system was used for phenotypic characterization of the c. valvarum strain. this is the first case of infective endocarditis caused by c. valvarum in germany and the first case worldwide affecting a prosthetic valve and lacking an obvious dental focus. | 2007 | 17475754 |
| detection of cardiobacterium valvarum in a patient with aortic valve infective endocarditis by broad-range pcr. | cardiobacterium valvarum, a fastidious gram-negative bacterium, was detected in the aortic valve of a previously healthy 63-year-old man by broad-range pcr and 16s rrna gene sequencing. in contrast to the patients in five previously published cases, our patient had neither a congenital bicuspid nor a prosthetic aortic valve. here, we present a case of c. valvarum native tricuspid aortic valve infective endocarditis and a review of the literature. | 2010 | 19797468 |

| cardiobacterium valvarum infective endocarditis and phenotypic/molecular characterization of 11 cardiobacterium species strains. | cardiobacterium valvarum is a newly recognized human pathogen related to infective endocarditis. cardiobacterium species are, however, only rarely the aetiology of infective endocarditis. an infective endocarditis case is presented and, additionally, phenotypic and phylogenetic comparison of a further 10 collection strains, representing the two species within the genus, was performed. c. valvarum was isolated from the blood and dna was present in valvular tissue (partial 16s rrna gene analysis) ... | 2010 | 21163827 |
| nonsurgical management of mitral valve endocarditis due to cardiobacterium valvarum in a patient with a ventricular septal defect. | cardiobacterium valvarum is a relatively novel agent of infective endocarditis. we describe the first case of infective endocarditis due to this pathogen in the asian pacific. this case is unique in its involvement of the mitral valve as well as its clinical resolution exclusively resulting from treatment with antibiotics without resorting to valve replacement/explantation. | 2013 | 23576538 |
| cardiobacterium hominis and cardiobacterium valvarum: two case stories with infective episodes in pacemaker treated patients. | cardiobacterium hominis and cardiobacterium valvarum are well known, though rare, etiologic agents of infective endocarditis. cardiac devices are increasingly implanted. | 2016 | 28077974 |
| cerebral vasculitis and cardiobacterium valvarum endocarditis. | 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. although both species rarely feature as the aetiological agent of endocarditis, cardiobacterium hominis has a higher incidence than cardiobacterium valvarum. for this c ... | 2012 | 22878249 |
| aortic vascular graft infection caused by cardiobacterium valvarum: a case report. | a 53-year-old man with a past medical history of total arch replacement surgery and severe aortic regurgitation presented with a 1-month history of persistent general malaise, anorexia, body weight loss and night sweats. his recent history included gingival hyperplasia for 6 years, gingivitis after tooth extraction 3 years before, prolonged inflammatory status for 4 months, fundal hemorrhage and leg tenderness for 2 months. a pathogen was detected from blood culture, but conventional microbiolog ... | 2014 | 25242585 |
