Susceptibility to Streptococcus viridans endocarditis in rabbits with intracardiac pacemaker electrodes or polyethylene tubing.

摘要: Abstract The susceptibility to endocarditis of rabbits following intracardiac placement solid cannulae (cardiac pacemaker electrodes) was compared the hollow polyethylene tubing equal diameter. Aortic valvular and mural endothelial lesions produced by transvenous electrodes 24 hours after insertion in were similar those tubing. Infective initiated injecting Streptococcus viridans intravenously. inoculum required produce infective 50 per cent with or about 10 5 colony forming units S. . titers streptococci vegetations both groups same. These studies indicate that predispose streptococcal as much cannulae.
