| late aortic homograft valve endocarditis caused by cardiobacterium hominis: a case report and review of the literature. | an unusual case of cardiobacterium hominis endocarditis involving an aortic homograft valve is presented. although the patient was young (a 17 year old man) and showed few of the characteristic features of the disease, the report does illustrate a number of the problems associated with this illness and highlights the need for the careful assessment of apparent culture negative endocarditis. the organism itself is susceptible to most antibiotics but further treatment, including surgery, may be ne ... | 2000 | 10768915 |
| infective endocarditis complicated with progressive heart failure due to beta-lactamase-producing cardiobacterium hominis. | we describe a 66-year-old woman with infective endocarditis due to cardiobacterium hominis whose condition, complicated by severe aortic regurgitation and congestive heart failure, necessitated aortic valve replacement despite treatment with ceftriaxone followed by ciprofloxacin. the blood isolate of c. hominis produced beta-lactamase and exhibited high-level resistance to penicillin (mic, >==256 microgram/ml) and reduced susceptibility to vancomycin (mic, 8 microgram/ml). | 2000 | 10790145 |
| diagnosis of cardiobacterium hominis endocarditis by broad-range pcr from arterio-embolic tissue. | a case of culture-negative endocarditis is reported, in which the diagnosis of cardiobacterium hominis endocarditis was made from arterio-embolic tissue removed by percutaneous transluminal embolectomy by broadrange polymerase chain reaction amplification of the 16 rrna gene, followed by single-strand sequencing. the use of this technique to identify etiologic agents from arterio-embolic material has not been reported so far. a serologic assay employing complement fixation against a crude antige ... | 1999 | 10885844 |
| optimisation of the prevention and treatment of bacterial endocarditis. | this paper reviews currently established guidelines for the prevention and treatment of bacterial endocarditis. endocarditis remains a life-threatening disease with substantial morbidity and mortality. primary prevention of endocarditis, whenever possible, is therefore very important. in an individual with endocarditis, rapid diagnosis and effective treatment are essential to good patient outcome. the guidelines discussed here are largely based on those issued by the american heart association. ... | 2001 | 11419916 |

| cardiobacterium hominis bioprosthetic mitral valve endocarditis presenting as septic arthritis. | we report an unusual case of cardiobacterium hominis bioprosthetic valve endocarditis presenting as septic arthritis. this remarkable presentation had clinical features consistent with endocarditis generally associated with highly virulent pathogens. a literature search has failed to disclose a report of septic arthiritis as a manifestation of c. hominis endocarditis. | 2002 | 11821177 |
| treatment and prevention of infective endocarditis. | the paper presents the most recent recommendations for the treatment and prevention of infective endocarditis (ie). the treatment of ie is complex and requires close collaboration among specialists in infectious diseases, cardiology, cardiac surgery and microbiology. the mainstay of medical treatment is antibiotic therapy. theoretical considerations regarding vegetations and antibiotics have practical consequences on the route and modalities of administration of antibiotics and on the techniques ... | 2002 | 11829727 |
| identification of cardiobacterium hominis by broad-range bacterial polymerase chain reaction analysis in a case of culture-negative endocarditis. | culture-negative bacterial endocarditis may be attributed to fastidious microorganisms, prior institution of antibiotic treatment, or both. we describe a case of culture-negative endocarditis in which a modified steiner stain revealed bacterial structures in the resected heart valve material. prompted by this finding, broad-range polymerase chain reaction (pcr) amplification of small-subunit ribosomal dna (16s rdna) was performed, and cardiobacterium hominis sequences were detected. this case de ... | 2002 | 11863484 |
| prevalent bacterial species and novel phylotypes in advanced noma lesions. | the purpose of this study was to determine the bacterial diversity in advanced noma lesions using culture-independent molecular methods. 16s ribosomal dna bacterial genes from dna isolated from advanced noma lesions of four nigerian children were pcr amplified with universally conserved primers and spirochetal selective primers and cloned into escherichia coli. partial 16s rrna sequences of approximately 500 bases from 212 cloned inserts were used initially to determine species identity or close ... | 2002 | 12037085 |
| [a case report of cardiobacterium hominis endocarditis]. | we here report a case of endocarditis due to cardiobacterium hominis in a 53-year-old patient, who presented with large vegetations on the mitral valve. good cooperation between clinicians and microbiologists and an efficient automated blood culture system were the decisive factors in establishing the diagnosis. early and appropriate treatment prevented the septic embolisms often observed in this pathology. | 2002 | 12147451 |
