Dispersal plays a prominent role in most conceptual models of community assembly. However, direct measurement of dispersal across a whole community is difficult at ecologically relevant spatial scales. For cryptic organisms, such as fungi and bacteria, the scale and importance of dispersal limitation has become a major point of debate. We use an experimental island biogeographic approach to mea...
Glomerulonephritis (GN) is an immunological phenomenon in bacterial endocarditis. These may be pauci-immune/vasculitic GN, post-infective GN, and sub-endothelial membranoproliferative glomerulonephritis. Each type of glomerulonephritis usually occurs in isolation. We report a case of infective endocarditis with dual existence of pauci-immune/vasculitic GN and post infective type of GN at the sa...
Cross-reactive antigens of clover roots and Rhizobium trifolii were detected on their cell surfaces by tube agglutination, immunofluorescent, and radioimmunoassay techniques. Anti-clover root antiserum had a higher agglutinating titer with infective strains of R. trifolii than with noninfective strains. The root antiserum previously adsorbed with noninfective R. trifolii cells remained reactive...
Intracardiac fistulas are rare complications of infective endocarditis. We report an unusual case of successful surgical repair of intracardiac fistula between the left ventricle and the left atrium in the course of infective endocarditis in a 20-year-old patient. According to this we conclude that timely diagnosis, proper antibiotic treatment, and early surgical intervention should improve the...
Background: Iran is a land of great heritage of ancient medical scholars. Herbal medicines, as a basement of treatment of diseases have been clearly described in the medical texts of these scholars including Rhazes, Avicenna, and others. Numerous plants are introduced in these texts to treat those diseases likely to be infective ones. Few attempts have been made to evaluate ethnopharmacological...
The median infective dose of Treponema pallidum subsp. pallidum and the production of immunity to reinfection in C4D guinea pigs have been determined with 10(1) to 10(6) organisms per infective dose. The mean infective dose is 10(2) organisms, and immunity--in those animals that demonstrated lesions--developed after 4.5 months postinfection.
Despite improvements in antibiotic regimens, patients with infective endocarditis (IE) have a high risk of valve replacement and death. Effective initial treatment depends on two steps: 1) diagnosis of the infecting organism, enabling specific antibiotic therapy, and 2) complete characterization of the anatomic extent of infection. Identification of the infecting organism requires culturing of ...
Infective endocarditis is a common serious infectious pathology in children. The most commonly identified organisms are of the streptococcus and staphylococcus species. Patients always have a fever. Other signs of infective endocarditis include Roth spots, splinter hemorrhages and Osler nodes. Blood cultures and echocardiography are very important in the establishment of the diagnosis. The diag...
BACKGROUND The purpose of this statement is to update the recommendations by the American Heart Association (AHA) for the prevention of infective endocarditis that were last published in 1997. METHODS AND RESULTS A writing group was appointed by the AHA for their expertise in prevention and treatment of infective endocarditis, with liaison members representing the American Dental Association,...
BACKGROUND Despite advances in medical, surgical, and critical care interventions, infective endocarditis remains a disease that is associated with considerable morbidity and mortality. The continuing evolution of antimicrobial resistance among common pathogens that cause infective endocarditis creates additional therapeutic issues for physicians to manage in this potentially life-threatening i...
