Comparison of electronic and viability counting methods for determination of postantibiotic effect of oxacillin on Staphylococcus aureus.
The postantibiotic effect of oxacillin on Staphylococcus aureus ATCC 6538P was determined under different test conditions by reference (viability counting) and semiautomated (electronic counting) methods. Differences in durations of the postantibiotic effect obtained with the two counting methods were not statistically significant. The semiautomated method provided a more rapid and convenient alternative to viability counting.
