Pathogenesis and treatment of endocarditis.
The rabbit model has been invaluable for in vivo studies in the pathogenesis and treatment of bacterial endocarditis. Both of the features of the mature bacterial vegetations in this rabbit model, i.e., absence of phagocytosis and decreased metabolic activity, provide evidence to support the concept that a rapidly bactericidal antimicrobial agent provides the optimal approach to the successful treatment of endocarditis. Imipenem, a carbapenem with a very broad spectrum of in vitro activity, has been shown to be rapidly bactericidal in animals and highly effective in the treatment of experimental bacterial endocarditis. In addition, twenty-six patients with endocarditis, caused largely by Staphylococcus aureus, have been successfully treated with imipenem/cilastatin.
