An 83-year-old woman with suppurative spondylitis was referred to our hospital due to active infective endocarditis with an expanding mobile vegetation and a high echoic mass on the posterior mitral leaflet. During the operation, the high echoic mass was found to be a chronically organized abscess, which was located at the base of the vegetation on the posterior leaflet and extended toward the annulus. The patient underwent a successfully emergent resection of the vegetation and mass, and valvuloplasty using an autologous pericardial patch with an excellent outcome.

The efficacy and tolerability of three different combination treatment regimens in human brucellosis were compared in 118 uncomplicated patients enrolled in a prospective study between May 1997 and December 2002. Brucellosis was diagnosed using standard clinical and microbiological findings. Patients with central nervous system involvement, spondylitis, endocarditis or children under 16 years of age were excluded from the study. Patients were randomly assigned to receive 400 mg of ofloxacin plus 600 mg of rifampicin (OR, n = 41), 200 mg of doxycycline plus 600 mg of rifampicin (DR, n = 45) or 1g intramuscularly streptomycin (administered for three weeks) plus 200 mg doxycycline (DS, n = 32) daily for 6 weeks. All patients were followed up at least 6 months after cessation of therapy. There was no statistical difference between the groups on relapse rates and clinical response to the treatment (P>0.05). Five patients in OR (12.8%), six patients in DR (14.3%) and three patients in DS groups (9.7%) suffered relapse. The side-effects were seen in eight (19.5%), 21 (46.7%) and eight (25.0%) patients of OR, DR and DS groups, respectively. The use of combination therapy of ofloxacin plus rifampicin for 6 weeks was found to be as effective as DR and DS. The side-effects of therapy in OR and DS groups was less severe than in the DR group.

Human brucellosis is a multiple organ disease that presents with fever and is most often transmitted via contaminated, unpasteurized goat milk and cheese. In chronic cases, focal complications (eg, spondylitis, neurobrucellosis and endocarditis) are frequently seen. Although the disease may be severely debilitating, the mortality rate is low. Fatal cases are often due to endocarditis. Because Brucella endocarditis is a rare complication (2% to 5%), therapeutic considerations are based on single-case experiences only. Therapy includes long-term antibiotic treatment using combinations of various antimicrobial drugs and surgical valve replacement when required. A case of Brucella endocarditis complicated by the infection of two valvular prostheses implanted after involvement of the mitral and aortic valve due to rheumatic fever is described. The patient was successfully treated by a medical and surgical approach. Therapeutic strategies in Brucella endocarditis are discussed in light of the current literature.

The purpose of this study was to evaluate the characteristics of infective endocarditis (IE) caused by S. bovis and compare them to those caused by streptococci of the viridans group (SVG). A prospective study was undertaken considering 55 consecutive cases of IE due to S. bovis and 41 to SVG over 18 years. The study was divided into two periods (1988-1996 and 1997-2005). S. bovis caused 24% of the IE in our centre and constituted the main aetiology for this disease, showing an increase of 358% during the second period studied. Biotype I was responsible for 94.5% of cases and there was a high degree of association with colon tumours (53%). Over the period of the study, 107 patients admitted to our hospital had bacteraemia caused by S. bovis and 310 patients had bacteraemia caused by SVG. In the first group, 55 (51%) were endocarditis cases, but only 41 (13%) of the patients with SVG bacteraemia had endocarditis (p < 0.0001). The distinguishing features of endocarditis caused by S. bovis in comparison with those caused by SGV were: a greater increase in cases during the 2nd period studied (from 12 to 43 vs. from 19 to 22, p < 0.01), a higher percentage of males (93% vs. 71%, p < 0.004), patients significantly older (median age 66 vs. 58.5, p < 0.004), less predisposing cardiopathy (42% vs. 76%, p < 0.0009), more bivalvular involvement (42% vs. 22%, p < 0.04), more spondylitis (9% vs. 0%, p < 0.04), a higher association with colonic tumours (53% vs. 5%, p < 0.0001), and a higher percentage of antibiotic resistance: erythromycin 66% vs. 19%, p < 0.0001; clindamycin 67% vs. 11%, p < 0.0001; cotrimoxazole 77% vs. 30.5%, p < 0.0001, respectively. IE due to S. bovis is an emergent disease in our environment, presenting different characteristics to those produced by SVG.

Streptococcus suis, a major global porcine pathogen, is an emerging zoonosis in Southeast Asia that triggered a 2005 outbreak in China. S. suis causes meningitis, sepsis, and endocarditis in both pigs and humans and involves significant mortality. We report the case of a previously healthy 50-year-old dairy farmer who developed S. suis type 2 endocarditis complicated by pulmonary embolism and spondylitis. He experienced a high fever, chills, fatigue, and worsening low back pain in the 6 weeks prior to admission. On physical examination, he had lumbar spine tenderness and weakness of the left leg. Blood culture identified penicillin-sensitive S. suis type 2. Echocardiography showed vegetation on the tricuspid valve, and magnetic resonance imaging (MRI) showed signs of spondylitis. The man reported sudden chest pain several days after admission, which computed tomography (CT) showed what was diagnosed as a septic pulmonary embolism. He was treated with penicillin G for 4 weeks and gentamicin for the first 2 weeks, followed by 2 weeks of oral amoxicillin, after which his symptoms gradually improved. The infection source was probably his dairy herd, since calves often bit his fingers while feeding and S. suis was found in their oral mucus. Over 400 cases of human S. suis infection have been reported globally, but this is, to our knowledge, the first known case of bovine transmission. All of Japan's 8 other cases involved occupational swine exposure, 5 of whom had injuries to their fingers. This emerging situation should be made known to all possibly involved in unprotected direct contact with swine and cattle, particularly when the skin could be compromised by cuts or abrasions.

Brucellosis is an extremely important disease around the world, especially in developing countries. Its clinical manifestations and severity vary with the patient population studied and the species of Brucella involved. The choice of regimen and duration of antimicrobial therapy should be based on whether focal disease is present or there are underlying conditions that contraindicate certain antibiotics (e.g. pregnant patients or children under 8 years old). Most individuals with acute brucellosis respond well to a combination of doxycycline plus aminoglycosides or rifampicin for 6 weeks. Monotherapy with doxycycline or minocycline, or a combination of doxycycline plus trimethoprim-sulfamethoxazole, or a quinolone plus rifampicin may be an alternative. Patients with focal disease, such as spondylitis or endocarditis, may require longer courses of antibiotics, depending on clinical evolution. Tetracycline monotherapy, especially with doxycycline, is a good option for patients with brucellosis with no focal lesions and a low risk of relapse. In this clinical situation, practitioners should avoid the use of high-cost or more toxic schedules.

The present report concerns a 46-year-old man who presented with acute prostatitis due to Brucella melitensis infection. He was first treated with doxycycline and ciprofloxacin, but after 3 months he was admitted again with the same diagnosis. The relapse was probably related to ciprofloxacin use, or the length of treatment not being sufficient. The patient was successfully treated with a combination of doxycycline and rifampin for 3 months. In conclusion, prostatitis due to Brucella, such as spondylitis, meningoencephalitis and endocarditis, should be treated for longer courses.

Brucellosis, a zoonotic infection caused by the genus Brucellae, is an ancient condition linked to the consumption of milk and milk products. The disease has global importance due to its impact. Therapeutic options for brucellosis rely mostly on uncontrolled, nonrandomized, non-blinded studies. The choice and duration of therapy are related to patient characteristics and the presence of a focal disease. The usual therapy of acute brucellosis is a combination of doxycycline plus rifampicin for 6 weeks. An aminoglycoside could be substituted for rifampin for the initial week of combination therapy. Other alternatives include a combination of doxycycline plus trimethoprim-sulfamethoxazole, or a fluoroquinolone plus rifampicin. The presence of spondylitis or endocarditis usually indicates that the required treatment will be of a longer duration or a combination of therapy. The article has the discussion of some recent patents related to antibiotic susceptibility and Brucellosis.

We isolated three strains of vancomycin intermediate Staphylococcus aureus (VISA) from a blood sample of a patient with infective endocarditis (VISA-1), postoperative pneumonia sputum (VISA-2), and pyogenic spondylitis blood sample (VISA-3). These VISA strains did not carry vanA, vanB, vanC1, or vanC2/C3 genes. Cell wall thickening was observed. VISA-1 and VISA-3 PFGE patterns showed the completely same pattern compared to the PFGE pattern of methicillin-resistant Staphylococcus aureus first isolated from patients 1 and 3. After 10 days on brain heart infusion agar, wall thickening in all three type of VISA was unchanged, but VISA-2 and VISA-3 reversed vancomycin susceptibility. The most suitable use of vancomycin in patients with MRSA infection thus appears to be in reducing the opportunity for cell wall thickening.

A 78-year-old woman was admitted to our hospital with lumbago. Her activities of daily living had previously been completely independent. However, she developed temporary chills in January 2009, that improved without treatment, but recurred on February 7, 2009 in association with left lumbago and loss of appetite. She was then referred to our hospital with a disturbance of consciousness and high fever on February 14. A blood test performed on admission revealed an elevated inflammatory response, coagulation disorder and low platelet count, and abdominal computed tomography demonstrated findings suggestive of pyogenic spondylitis. The patient was therefore admitted and treated with antibiotic therapy; however, she died on day 8 due to complications of disseminated intravascular coagulation. An autopsy showed isolated pulmonary valve endocarditis. The patient's history was later found to include regular dental treatment, and the same Streptococcus group G was detected in cultures of the sputum, blood and vegetation. It is important to interview patients regarding their history of dental treatment, particularly elderly individuals with fever of unknown origin.
