BACKGROUND: Bartonella koehlerae has been recently described as a new cat- and cat fleas-associated agent of culture-negative human endocarditis. It has been also encountered in one dog from Israel and six dogs from the USA, but other clinically relevant reports involving this bacterium are lacking. RESULTS: A 7-year-old intact male mixed dog presented with clinico-pathological signs consistent with mitral endocarditis and cutaneous hemangiosarcoma. Molecular studies revealed the presence of Bartonella koehlerae DNA in samples from blood and mitral valve tissue...

Since the reclassification of the genus Bartonella in 1993, the number of species has grown from 1 to 45 currently designated members. Likewise, the association of different Bartonella species with human disease continues to grow, as does the range of clinical presentations associated with these bacteria. Among these, blood-culture-negative endocarditis stands out as a common, often undiagnosed, clinical presentation of infection with several different Bartonella species. The limitations of laboratory tests resulting in this underdiagnosis of Bartonella endocarditis are discussed...

A ruptured sinus of Valsalva aneurysm rarely accompanies the aortic and tricuspid valve endocarditis. A 36-year-old woman presented with low-threshold dyspnea on exertion and fever. Transthoracic and transesophageal echocardiography showed a ruptured noncoronary sinus of Valsalva aneurysm with large vegetations on the tricuspid and aortic valves, resulting in moderately severe tricuspid regurgitation and severe aortic regurgitation. Blood culture was negative. The patient was initially treated with antibiotics and then subjected to the surgical repair of the sinus of Valsalva aneurysm and the tricuspid and aortic valve replacement...

A 7-year-old female child presented with pyrexia of unknown origin. She had received an empirical regimen of antibiotic for possible endocarditis. Evaluation included multiple imaging supports and blood culture. She had left main coronary artery to right atrium coronary cameral fistula, restricted patent ductus arteriosus, vegetation at the right atrial exit of fistula and negative blood culture. Ongoing fever more than 2 weeks, oscillating vegetation in the echo and histopathological evidence of healing vegetation suggested definite diagnosis of infective endocarditis...

BACKGROUND: The causative organism in cardiovascular implantable electronic device (CIED) infection is usually diagnosed with the cultures from blood, removed leads, and/or infected pocket material. The cultured organism, however, is sometimes different among these samples. METHODS: Two hundred sixty patients with CIED infection, who underwent lead extraction between April 2005 and December 2014, were analyzed. More than two blood culture sets, all the extracted leads, and swab culture of the pocket were sent to the laboratory for culture...

Infective Endocarditis (IE) is an endocardial infection usually caused by bacteria that affects not only the native heart valves but also, with increasing frequency intravascular implanted devices and congenital heart diseases. Despite medical advances, IE remains a life-threatening disease with substantial morbidity and mortality. In Africa, its diagnosis and treatment are still a major challenge in clinical practice. The objective of this work was to study the epidemiological, clinical features, diagnostic techniques currently used in medical practice and the range of micro-organisms that are responsible...

Blood-culture negative endocarditis (BCNE) accounts for up to 35% of all cases of infective endocarditis (IE) and is a serious life-threatening condition with considerable morbidity and mortality. Rapid detection and identification of the causative pathogen is essential for timely, directed therapy. Blood-culture negative endocarditis presents a diagnostic and therapeutic challenge. Causes of BCNE are varied including: treatment with antibiotic agents prior to blood culture collection; sub-optimal specimen collection; and/or infection due to fastidious (eg...

OBJECTIVE: The management of infective endocarditis (IE) may differ from international guidelines, even in reference centers. This is probably due to the fact that most recommendations are not based on hard evidence, so that the consensus obtained for the guidelines does not represent actual practices. For this reason, we aimed at evaluating this question in the particular field of antibiotic therapy. METHODS: Thirteen international centers specialized in the management of IE were selected, according to their reputation, clinical results, original research publications and quotations...
