Current Characteristics of Infective Endocarditis in Japan

Inhibitory effect of beta-pinene, alpha-pinene and eugenol on the growth of potential infectious endocarditis causing Gram-positive bacteria

“…It has been related to the development of antibiotic resistance by IE causing agents, mainly when regarded the Staphylococcus genus because the appearance of methicillinresistant Staphylococcus aureus (MRSA) (Nakatani et al, 2003;Ishiwada et al, 2005). Some researchers have reported that the rising of MRSA strains has been responsible for an increase in the action of Staphylococcus genus as IE causing agent.…”

“…The successful history of microbial chemocontrol lies in the continuous rising of microbial strains with resistance to the classical antibiotics (Notermans, HoogenboonVerdegaal, 1992). Researches regarding the antimicrobial activity of phytochemicals have been yet little emphasized being the most studies addressed to evaluate the antimicrobial effect of essential oils and extracts (Nascimento et al, 2000;Souza et al, 2005).…”

Infective Endocarditis and Acute Purulent Pericarditis in a Patient with Hyperglycemia

“…The initial treatment usually cannot await blood culture results when the symptoms progressively worsen, so the physician must choose drugs to cover the species of organisms most likely to be present. Streptococcus species, coagulasenegative staphylococci, Gram negative bacilli and fungi are common bacteria found in infective endocarditis (1,5,13). In a recent series, staphylococci, and in particular Staphylococcus aureus, has become the most common cause of infective endocarditis with native-valve endocarditis.…”

NVS and Staphylococci in the Oral Cavity – A Cause of Infective Endocarditis

“…The overall incidence rate has been found to range from 4.4 to 11.6 cases per 100,000 person-years (Berlin et al, 1995;Tleyjeh et al, 2005;Fedeli et al, 2011). Cardiac valvular abnormalities that cause eddy-or jet-type vascular flow are strong risk factors (Strom et al, 1998;Nakatani et al, 2003). Abnormal vascular flow around valves causes clotting deposits, and bacteria which enter the bloodstream and become attached to clots then grow by forming biofilm.…”

“…Until recently, viridans streptococci have been considered as the most common causative microorganisms of IE and detected at a range from 30% to 50% (Strom et al, 1998;Nakatani et al, 2003;Murdoch et al, 2004;Tleyjeh et al, 2005;Alshammary et al, 2008). Viridans streptococci are composed of a total of 21 species, including S. mitis, S. anginosus, S. salivalius, and S. bovis (Kawamura et al, 1995).…”
