[Proceedings: Experimental endocarditis. Experimental basis and prophylaxis].
A simple model has been developed for the production of bacterial endocarditis in rabbits. The principle depends on the insertion of a polyethylene catheter into the venous or arterial system so that the tip rests in the heart cavity in which endocarditis is to be established. After catheter placement, intravenous injection of any one of a variety of microorganisms regularly produces infective endocarditis. The characteristics of the infection in rabbits are similar to those observed in infective endocarditis in man. The production of streptococcus viridans infections in previously immunized animals leads to the development of diffuse glomerulonephritis. Translating antibiotic doses on a weight basis, prophylactic antibiotic treatment programs recommended in man have been shown to be ineffective in rabbits. If the activity of antibiotics in this model infection in rabbits can be assumed to be comparable to that in man, it is necessary that we reconsider the currently accepted recommendation for prophylaxis and treatment of infective endocarditis in man.
