The effectiveness of antibiotic prophylaxis against endocarditis was assessed by testing the bactericidal and bacteriostatic action in serum of 12 healthy volunteers who had taken the recommended antibiotics according to laid down guidelines. Blood was obtained from these subjects every two hours for 12 hours after oral intake of amoxicillin (3 g as a single dose), clindamycin (600 mg a single dose) or erythromycin (1.5 g plus another 0.5 g after six hours), the serum being tested against three Strep. viridans strains. Two of the three strains were "tolerant", i.e. in relation to the minimal inhibition concentration (MIC) their growth was inhibited, but--in relation to the minimal bactericidal concentration (MBC)--they were not killed. A bacteriostatic effect by amoxicillin and clindamycin was demonstrated by a micromethod against all three strains during the 12-hour period. But erythromycin did not achieve bacteriostasis in all serum samples. A bactericidal effect was demonstrated only in those samples that contained amoxicillin, and then only against the non-tolerant of the three strains. These results support the view that amoxicillin and clindamycin are effective in the prophylaxis against Strep. viridans bacteraemia because of their constant bacteriostatic effect, as measured in serum.
