A 59-year-old man presented with an internal carotid artery (ICA) bacterial aneurysm which ruptured during surgery for treatment of another bacterial aneurysm. He had been admitted to our hospital because of the recurrence of colon cancer. He had undergone aortic and mitral valve replacement because of closure incompetence due to bacterial endocarditis two months previously. Two months after treatment for colon cancer, he developed fever, and arterial blood culture demonstrated. Staphylococcus epidermidis. A few days later, he suddenly suffered severe headache and vomiting, followed by deterioration of consciousness. CT showed subarachnoid hemorrhage and angiography showed a saccular aneurysm at the opercular portion of the left middle cerebral artery (MCA). Immediate clipping of the aneurysm was attempted. The carotid cistern was opened via a left frontotemporal craniotomy, but an ICA aneurysm, which had not been previously recognized, ruptured suddenly. The ICA aneurysm was wrapped with Vascwrap with some difficulty. The MCA aneurysm was then trapped. Postoperatively, the patient continued to be stuporous for a few days. Two weeks later, he died of complications caused by pneumonia. Bacterial aneurysm is more likely to be located in the distribution of the distal arterial tree, mainly in the distribution of the MCA. The difficulty of preoperative diagnosis and the unpredictable clinical course of bacterial aneurysms are emphasized.

Left ventricular (LV) outflow tract-right atrial (RA) communication associated with bacterial endocarditis is described in a 6-year-old intact male Great Pyrenees dog with a 4- to 5-day history of fever, lethargy, weight loss, severe regenerative anemia, and asplenia. Typical vegetative mural endocardial lesions were observed grossly. Histologic evaluation revealed small gram-negative coccobacilli that were consistent with Bordetella avium-like organisms. These bacteria were associated with severe endocardial inflammation characterized by neutrophilic infiltration, extensive necrosis of endocardium, and fibrin deposition. LV-RA shunt (Gerbode defect) is a rare cardiac defect in humans that can be either congenital or, more rarely, secondary to septic endocarditis, valve replacement procedures, or thoracic trauma. B. avium-like organisms causing septicemia and endocarditis in immunocompromised and asplenic human patients have been described. To our knowledge, no previous descriptions of Gerbode defect associated with bacterial endocarditis in domestic animals have been reported in veterinary literature.

Endocarditis due to Pasteurella pneumotropica are very rarely described. We report a new case of bacterial endocarditis in a 43 years-old patient with mitral stenosis. The patient was admitted to the hospital for lethargy, malaise and hemiparesis. On physical examination, a new systolic murmur was found. Transthoracic echocardiography revealed a vegetation on the mitral valve. Three blood culture sets were drawn and after 24 hours of incubation, the last two sets yielded Pasteurella pneumotropica and cell wall deficient forms (L-forms). The patient was successfully treated with gentamicin and ceftriaxone and underwent mitral valve replacement.

Infective endocarditis (IE) is a life-threatening condition with adverse consequences and increased mortality, despite improvements in treatment options. Diagnosed patients usually require a prolonged course of antibiotics, with up to 40-50% requiring surgery during initial hospital admission. We report a case of a 42-year-old intravenous drug user who presented feeling generally unwell, with lethargy, rigours, confusion and a painful swollen right leg. He was subsequently diagnosed with Proteus mirabilis endocarditis (fulfilling modified Duke criteria for possible IE) and deep vein thrombosis (DVT). He was successfully treated with single antibiotic therapy without needing surgical intervention or requiring anticoagulation for his DVT. Proteus endocarditis is extremely uncommon, with a limited number of case reports available in the literature. This case illustrates how blood cultures are invaluable in the diagnosis of IE, especially that due to unusual microorganisms. Our case also highlights how single antibiotic therapy can be effective in treating Proteus endocarditis.

An 11 yr old female spayed golden retriever weighing 30.3 kg presented for evaluation of progressive lethargy, anorexia, tachypnea, stiff gait, and nonlocalized pain. On physical exam, the patient was febrile and tachycardic, and an arrhythmia with pulse deficits was noted. Clinicopathological abnormalities included thrombocytopenia, leukocytosis, nonregenerative anemia, and mild hypoalbuminemia. The patient progressed overnight to develop a productive cough, and an echocardiogram performed the next morning revealed irregular proliferative lesions of the pulmonic valve with moderate pulmonic regurgitation. Subsequent blood cultures grew two organisms: alpha-hemolytic streptococci spp. and Empedobacter brevis. The dog was treated with appropriate intravenous antibiotics for 2 wk and then switched to oral therapy. The clinicopathologic abnormalities, fever, and clinical signs resolved with oral antibiotic treatment. To the authors' knowledge, this case report represents the first detailed published case of bacterial endocarditis with E brevis bacteremia involving the pulmonic valve. The clinical presentation, diagnosis, treatment, and follow-up are discussed.

A brown howler monkey (Alouatta guariba clamitans) was presented with lethargy, hyporexia, cough and heart murmur. The complementary tests and necropsy revealed pleuropneumonia, bacterial endocarditis and interventricular septal defect. To the best of our knowledge, this is the first report of increased cardiac troponin I levels in this species.

Infective endocarditis (IE) with Staphylococcus aureus is associated with intravenous drug abuse or infected cardiac devices and commonly presents with non-specific constitutional symptoms. A 53-year-old female presented to the hospital with back pain, altered mental status, fever, and tachycardia. Due to patient's lethargy and decline in respiratory effort, she was intubated and lumbar puncture was performed that revealed neutrophil-predominant leukocytosis of the cerebrospinal fluid. The patient was empirically started on ceftriaxone and vancomycin, and blood cultures were positive for methicillin resistant Staphylococcus aureus (MRSA). A chest X-ray demonstrated pulmonary congestion and an implanted pacemaker; furthermore, a transesophageal echocardiogram (TEE) revealed a vegetation on the atrial lead of the pacemaker. As the patient's condition improved after a few days, she was extubated and was able to provide a clear history. The source of her infection was a pus pocket around her pacemaker which was placed two months prior to her admission. As expected, the infection resolved with proper source control and antibiotic therapy.

A 2.5-year-old female intact British Shorthair was presented for progressive complaints of abdominal distention, increased respiratory effort, lethargy and hyporexia. Based on the clinical presentation and a loud heart murmur, a cardiac cause was suspected. An echocardiogram was performed and the presumptive diagnosis of infective endocarditis of the aortic, mitral and pulmonic valves was made. Antemortem blood culture and postmortem valve biopsy confirmed bacterial endocarditis with Enterococcus hirae as etiological agent. To the authors' best knowledge, this case report is the first to describe an infective endocarditis with vegetative lesions on three cardiac valves associated with a ventricular septal defect in a cat, and Enterococcus hirae as causative agent for endocarditis in small animals.
