Laboratory bacterial isolate.
Antibiotic susceptibility to a range of concentrations of an antibiotic by broth dilution, including microbroth dilution in commercial systems.
Susceptibility testing of streptococcal or enterococcal isolates causing endocarditis;
The MIC of a particular antibiotic is reported in mg/L.
The MIC is the lowest concentration of antibiotic which inhibits the growth of the bacterium.
In patients with endocarditis the test helps to determine whether a second antibiotic should be added (eg, for a MIC of penicillin for Streptococcus mutans of >0.1 mg/L, the addition of gentamicin to penicillin therapy is indicated).
