The so-called nonpathogenic neisseriae are common inhabitants of the upper respiratory tract in humans and are not usually regarded as pathogens. Neisseria meningitidis on the contrary may cause severe disease. These organisms are an uncommon cause of infective endocarditis. The authors report a case of a 64 year-old male, type II diabetic, previously asymptomatic, admitted to hospital because of fever, aphasia and right hemi-paresis. A systolic murmur was heard at the cardiac apex, and three blood cultures were positive for Neisseria meningitidis. The echocardiogram showed a vegetation on the posterior leaflet of the mitral valve, allowing the diagnosis of meningococcal endocarditis. The patient's clinical condition improved on intravenous penicillin therapy, and regression of fever, disappearance of the neurological signs and of the mitral valve vegetation were observed.

We report a case of a bacterial brain abscess presenting symptoms of 'sudden stroke-like' onset, associated with infective endocarditis. A 59-year-old woman experienced a sudden stroke-like onset of left hemiplegia. Computed tomography (CT) and magnetic resonance imaging (MRI) were performed on the day of ictus. No lesion responsible for the symptom was seen on either CT or a T2 weighted image (T2WI), but a diffusion-weighted image (DWI) revealed focal increased signal intensity in the right frontal lobe. An initial diagnosis of acute embolic infarction associated with infective endocarditis was made. Although the patient's neurological state had been stable, motor paresis of her left extremities became worse starting one month after her admission. MRI with gadolinium-diethylenetriaminepenta-acid (Gd-DTPA) at 37 days after admission showed an irregular-shaped ring-enhancement lesion located at the same place as the initial infarction, and in the left frontal lobe. Surgical drainage of the lesion in the right frontal lobe was performed, and diagnosed as a bacterial abscess. The exact mechanism of a bacterial brain abscess presenting with 'sudden stroke-like' onset is unknown, but various hypotheses have been proposed. One is that paroxysmal septic emboli lead to abscess formation within or near the area of embolic infarction. Our case showed that the creation of a brain abscess followed embolic strokes, and that this hypothesis was demonstrated by MRI carried out on the day of ictus.

Veillonella species is a rare cause of endocarditis. We report a case of a 49-year-old man with Veillonella parvula prosthetic valve endocarditis who presented with acute cardiac failure due to valvular dehiscence. His clinical course was complicated by cortical blindness and limb paresis as a result of cerebral embolism. The endocarditis was successfully treated with urgent valve replacement surgery and a prolonged course of metronidazole.

The Williams-Beuren syndrome is a rare genetic disease characterized by: (a) typical facial features; (b) psychomotor retardation with a specific neurocognitive profile; (c) cardiovascular condition and (d) likely transient hypocalcemia in infancy. The objective of this study was to describe the clinic evolution and diagnosis of patient with this syndrome that was associated with endocarditis caused by Streptococcus parasanguis in the ascending aorta and an aneurism located in the fronto-temporal area, which produced a parenchymal hematoma in the left lobe, and subarachnoid hemorrhage. He was treated with ceftriaxone and dicloxacillin. Then we proceeded to correct the aneurysm and perform vegetation resection in aortic arteries with supravalvular aortic stenosis correction. The evolution after one year has been favorable and is currently without neurologic sequelae. A 5-year-old male patient presented a diagnosis of supravalvular aortic stenosis. After cardiac catheterization was performed, he presented a fever and right side paresis. The echocardiogram showed multiple vegetations in the ascendant aortic arch and the supraortic arteries. The blood cultures reported S. parasanguis. The magnetic resonance showed a subarachnoid hemorrhage with an aneurysm and a hematoma.

A 52-year-old woman was admitted to our hospital for acute right hemi-paresis, left homonymous hemianopia, and fever. Magnetic resonance imaging of the brain showed multiple cerebral infarctions and transesophageal echocardiography (TEE) revealed a vegetation on the posterior leaflet of her mitral valve. Mitral valve repair was performed under a diagnosis of infective endocarditis (IE). Further multiple cerebral infarctions occurred on the 11th postoperative day, resulting in left hemiplegia and dysarthria. TEE revealed vegetations on her mitral valve and mitral valve replacement (MVR) was performed. Microscopic examination of the resected valve showed mild lymphocytic infiltration, but no bacterial or fungal organisms were detected. On the 66th day after the initial surgery, she developed deep vein thrombosis and acute pulmonary embolism. Abdominal computed tomography showed a huge ovarian tumor, and TEE demonstrated vegetations on the left atrial wall, the aortic valve, and the mechanical valve immobilizing one of the leaflets. The patient was finally diagnosed as having Trousseau syndrome caused by an ovarian tumor and non-bacterial thrombotic endocarditis( NBTE). Three months after the initial operation, redo MVR was performed and aortic valve vegetations were removed. Four days later, the ovarian cancer was resected. Her postoperative course was uneventful and she was discharged on foot on the 143rd day after the initial operation. NBTE caused by malignancy is rare but must be considered when managing endocarditis.

A six-year-old female goat was presented to the veterinary teaching hospital of the University of the West Indies with a history of progressive hind-limb paresis lasting two weeks. The doe developed a grade 6/6 holosystolic murmur during hospitalisation. Echocardiography revealed vegetative growths attached to cusps of the mitral and aortic valves. There was an accelerated aortic flow at 2.9 m/s and aortic insufficiency. The aortic vegetation was prolapsing into the left ventricle during diastole, causing it to contact the septal mitral valve leaflet. A diagnosis of mitral and aortic vegetative endocarditis, with a mitral kissing vegetation and mild aortic stenosis, was reached. The patient was placed on broad-spectrum antimicrobials. A short-term follow-up showed no resolution of clinical signs, and the animal eventually died. Post-mortem examination showed severe vegetative, fibrino-necrotic, aortic and mitral valve lesions. The goat also had a severe fibrino-suppurative mastitis. Histopathology confirmed the lesions to be vegetative endocarditis.

A 15-year-old, female cockatoo (Cacatua alba) was presented with a history of intermittent cloacal prolapse of 1-year duration. After each prolapse, the owner would digitally reduce the distended cloacal tissue within approximately 12-24 hours, for short-term resolution. The cockatoo was examined 3 times over a 7-month period and received supportive care with leuprolide acetate, behavioral modification, and diet change. After the third examination, the owner decided to proceed with a surgical cloacopexy. Five days after the last examination and before the procedure was scheduled, the cockatoo was reexamined for acute onset of weakness, anorexia, lethargy, and right-leg paresis. Despite supportive treatment, the cockatoo's clinical condition declined, and it went into respiratory arrest. Resuscitative efforts, including manual ventilation and cardiovascular support, were unsuccessful, and the bird died. Results of postmortem examination revealed vegetative endocarditis with intralesional bacteria cultured as Staphylococcus aureus, right-hindlimb myonecrosis, hepatitis, and nephritis. We suspect that the source of the hematogenous S aureus infection in this cockatoo was translocation from the owner's skin from the repeated manual manipulation and replacement of the prolapsed cloacal tissue.
