Ochrobactrum anthropi is a Gram-negative bacillus widely distributed in nature. It is a low virulence and low pathogenic microorganism and human infection by this agent is considered rare. This microorganism can cause bacteremia and in some cases can lead to osteomyelitis and endocarditis. Included in Brucellaceae family, this bacterium is phenotypically and genetically closely related to the Brucella genus and may be misidentified by rapid identification systems. The authors describe a patient admitted to the Infectious Diseases Department with vertebral osteomyelitis initially identified as Ochrobactrum anthropi ...

PURPOSE: We describe a case of Lyme endocarditis which, to our knowledge, is the first reported case confirmed by molecular diagnostics in the United States. BACKGROUND: Valvular involvement as a manifestation of Lyme carditis is rare4 . The first case describing a possible association between Lyme disease and cardiac valvular disease in the United States was published in 19935 . Since that time, there have been 2 cases of Lyme endocarditis confirmed by Borrelia positive 16S rRNA polymerase chain reaction (PCR) and sequencing from valvular tissue8,10 and reported from Europe...

A 44-year-old man presented with fever (low to high grade) for 2-month duration despite treatment with oral antibiotics and antipyretics. Further, enquiry did not yield any potentially explanatory clues to a diagnosis. Physical examination revealed only left axillary lymphadenopathy, but was otherwise unremarkable. A number of diagnosis included tuberculosis, malignancy, lymphoma, connective disease disorder and infective endocarditis. Further evaluation revealed severe anaemia due to iron deficiency which was supported with blood transfusion and oral iron supplementation...

Background: Brucellosis is a bacterial infection, caused by the nonmotile gram-negative aerobic coccobacilli. The clinical manifestation of brucellosis is variable, ranging from mild disease to severe disease. The gold standard test to confirm the diagnosis of brucellosis is assaying blood, bone marrow, or other body fluids or by tissue culture. Preferred first-line treatment in adults with uncomplicated, nonlocalized disease consists of doxycycline-aminoglycoside combination. The recommended duration of treatment is 6 weeks...

A 47-year-old woman with a medical history of Raynaud's phenomenon presented with fever, cough and shortness of breath. She was found to have left lower lobe consolidation and pleural effusion and was treated as a case of pneumonia. During the hospital course, her respiratory status worsened, and she was intubated on the third hospital day. To investigate the high A-a gradient, a Computerized Tomographic Pulmonary Embolism (CTPE) study was done which identified a large left lower pulmonary artery embolism. She was also found to have a new murmur, and an echocardiogram demonstrated a large lesion on tricuspid valve...

Although vancomycin administration is recommended for the treatment of infective endocarditis (IE) caused by methicillin-resistant Staphylococcus aureus (MRSA), it is unclear whether an alternative agent, daptomycin, can be used to treat IE with pulmonary complications. A 26-year-old female who had undergone surgical repair of a ventricular septal defect as an early teenager presented with fever, headache, and vomiting. She was admitted to our hospital and diagnosed with right-sided IE with septic pulmonary embolism caused by MRSA...

INTRODUCTION: Infectious endocarditis (IE) is a rare disease with a high mortality. In 2009, the European society of cardiology restricted antibiotic prophylaxis to a smaller number of cardiac conditions with very high risk for IE. Did these changes in the guidelines have an impact on the epidemiological and bacteriological profile of IE? AIM: The main aim of our work was to study the evolution of the microbiological profile of IE from 1991 to 2016. METHODS: We realized an analytic retrospective study comparing two groups: group 1 included patients admitted for a certain IE before September 2009 and group 2 those admitted after that date...

Marantic or nonbacterial thrombotic endocarditis is characterized for the presence of vegetations formed by a meshwork of fibrin and other cellular material similar a blood clot, without the presence of microorganisms. It is often related with tumors and chronic inflammatory states. We report a 49 years old female with a history of weight loss and asthenia, presenting with multiple cerebrovascular attacks and fever. Blood cultures were negative and the fever did not subside with antibiotic treatment. Trans esophageal echocardiogram showed a mitral valve vegetation and thickening of the free edge of both leaflets...

RATIONALE: Infective endocarditis (IE) is a life-threatening disease, mostly caused by gram-positive bacteria. Gram-negative bacteria were identified as a causative organism in relatively small number of cases. Although, antibiotic-resistant Escherichia coli is common cause of gram-negative endocarditis, AmpC beta-lactamase (BL)-harboring E coli is very rare cause of IE. Furthermore, emphysematous endocarditis is also a very rare manifestation of E coli infection. PATIENT CONCERNS: We report a case of 80-year-old female patient presenting with dizziness, fever, and altered mental status, who was finally diagnosed with emphysematous endocarditis caused by E coli harboring an AmpC BL gene...

Burke A Cunha, Bertamaria Dieguez, Alena Varantsova
Culture negative endocarditis (CNE) is a common concern in patients with fever, heart murmur, cardiac vegetation, and negative blood cultures. The diagnosis of CNE is not based only on negative blood cultures and a cardiac vegetation. The clinical definition of CNE is based on negative blood cultures plus the findings of culture positive infective endocarditis (IE), e.g., fever, cardiac vegetation, splenomegaly, peripheral manifestations. Because embolic splenic infarcts may occur with culture positive IE, some may assume that splenic infarcts are a sign of CNE...

RATIONALE: Fever of unknown origin (FUO) can be determined by different conditions among which infectious diseases represent the main cause. PATIENT CONCERNS: A young woman, with a history of aortic stenosis, was admitted to our unit for a month of intermittent fever associated with a new diastolic heart murmur and splenomegaly. Laboratory tests were negative for infectious screening. The total body computed tomography (CT) scan excluded abscesses, occulted neoplasia, or lymphadenopathy...

Blood culture-negative endocarditis (BCNE) may represent up to 70% of all endocarditis cases, depending on series. From 2001 to 2009, we implemented in our laboratory a multimodal diagnostic strategy for BCNE that included systematized testing of blood, and when available, valvular biopsy specimens using serological, broad range molecular, and histopathological assays. A causative microorganism was identified in 62.7% of patients.In this study from January 2010 to December 2015, in an effort to increase the number of identified causative microorganisms, we prospectively added to our diagnostic protocol specific real-time (RT) polymerase chain reaction (PCR) assays targeting various endocarditis agents, and applied them to all patients with BCNE admitted to the 4 public hospitals in Marseille, France...

Background and Objectives: Infective endocarditis (IE) is a microbial infection of the endothelial surface of the cardiac-valves. Rapid diagnosis, effective treatment and prompt recognition of complications are essential, in order to improve the outcome. We retrospectively reviewed and determined the clinical characteristics, microbiological profile and management strategies of IE cases, changing microbial spectrum of pathogens and outcome in Native Valve Endocarditis (NVE) and Prosthetic Valve Endocarditis (PVE) cases...

A 77-year-old man visited our hospital with unstable gait following 2 months of anorexia. Brain MRI showed multiple infarcts; cardiac echocardiography revealed mitral-valve vegetation; and blood culture revealed methicillin-resistant coagulase-negative staphylococci. The patient was diagnosed with infective endocarditis (IE). Subarachnoid hemorrhage (SAH) developed ten days after antibiotic treatment. Intracranial aneurysm was not found. We speculated that chronic inflammation of the cerebral arterial walls by bacteria of low virulence was associated with SAH complication...

BACKGROUND: Prosthetic valve endocarditis (PVE) due to methicillin resistant Staphylococcus aureus (MRSA) is a rare disease with significant mortality and morbidity. With the emerging resistance and adverse effect profile of vancomycin which is the standard treatment, there is a compelling necessity of an effective alternative for vancomycin. Linezolid is proved as such an agent for infections caused by MRSA in other sites. However to-date the evidence for successful use of linezolid for MRSA prosthetic valve endocarditis is limited only for few case studies...

A 78-year-old man who had undergone aortic valve and ascending aorta replacements presented with fever and was referred to our hospital. Blood culture revealed Gram-positive cocci, thus antibiotic therapy was started. Brain magnetic resonance imaging showed fresh cerebral infarction without cerebral haemorrhage or mycotic aneurysm. Transoesophageal echocardiogram revealed a vegetation that was attached to the right coronary cusp. The patient underwent successful aortic valve neocuspidization using glutaraldehyde-treated bovine pericardium...

Anterior mitral valve leaflet (AMVL) perforation is most commonly seen in the setting of infective endocarditis. We present a case of AMVL perforation in a previously healthy 62-year-old male who presented with a six-month history of worsening dyspnea and peripheral edema. Blood cultures, inflammatory markers, and autoimmune profile were negative. Transthoracic echocardiography demonstrated severe mitral regurgitation (MR) with a possible AMVL perforation, which was confirmed by three-dimensional transesophageal echocardiography as a well-circumscribed hole in the A2 segment...
