In an attempt to gain information about the "incubation period" of subacute bacterial endocarditis, the literature was searched for case reports stating a specific interval between an event likely to cause bacteremia and the onset of symptoms. In 76 cases of streptococcal endocarditis for which this information was given, the median "incubation period" was one week. Symptoms began within two we...

INTRODUCTION Micrococcus luteus endocarditis is a rare case of infective endocarditis. A total of 17 cases of infective endocarditis due to M luteus have been reported in the literature to date, all involving prosthetic valves. To the best of our knowledge, we describe the first case of native aortic valve M luteus endocarditis in an immunosuppressed patient in this report. CASE REPORT A 74-y...

ccurate diagnosis of prosthetic heart valve infection has major implications on patient management and outcome. If the presence of prosthetic or periprosthetic valve endocarditis is misclassified, it can lead to delayed antibiotic or surgical intervention, which may adversely affect patient outcomes, and that is not inconsequential. Prosthetic valve endocarditis constitutes up to 30% of all cas...

AIM To compare the clinical and morphological characteristics of patients with Streptococcus bovis endocarditis with those of patients with endocarditis caused by other microorganisms. METHODS 177 consecutive patients (Streptococcus bovis, 22; other streptococci, 94; staphylococci, 44; other, 17) with definite infective endocarditis according to the Duke criteria were included. All patients u...

This study was conducted to find out the antimicrobial susceptibility characteristics of Escherichia coli, Klebsiella pneumoniae, and Klebsiella oxytoca isolated from invasive disease cases at tertiary care university hospital in the central region of Japan from 2008 to 2010. Invasive bacterial disease was defined as isolation of bacteria from a normally sterile body site. Bacteriawere identifi...

Klebsiella oxytoca was isolated from the blood of a leukemic patient. The typical pathogenicity of Klebsiella oxytoca was observed in the patient. The pathogenicity of several Klebsiella oxytoca strains isolated from blood, urine and sputum of different patients was examined in mice, and it was found that Klebsiella oxytoca isolated from the blood had a higher toxicity than the others.

Infective endocarditis is an uncommon disease, with an estimated incidence of 3.1 to 3.7 episodes per 100 000 inhabitants/year. The incidence is highest in elderly people. The microorganisms most frequently isolated in infective endocarditis are staphylococci and streptococci. In the last few decades, the spectrum of heart diseases predisposing to infective endocarditis has changed, since degen...

OBJECTIVES The aim of this study was to assess the mean platelet volume (MPV), an indicator of platelet activation in patients with infective endocarditis. SUBJECTS AND METHODS Twenty-nine patients with infective endocarditis and 29 healthy subjects were studied. Plasma MPV values in patients and control subjects were measured on admission and after 2 weeks of specific treatment of infective ...

BACKGROUND Many studies in the literature have warned of the need for investigation of colonic lesions among patients, especially elderly ones, who have bacteremia and/or endocarditis from Streptococcus bovis. Bacteremia and infectious endocarditis from Streptococcus bovis may be related to the presence of neoplastic lesions in the large intestine and hepatic disease. AIM This report describe...
