Microbiology
Penicillinase-resistant penicillins exert a bactericidal action against penicillin-susceptible microorganisms during the state of active multiplication. All penicillins inhibit the biosynthesis of the bacterial cell wall.
Dicloxacillin sodium has been shown to be active against most strains of the following microorganisms, both in vitro and in clinical infections as described in the INDICATIONS AND USAGE section.
Aerobic Gram-Positive Microorganisms
Staphylococcus spp. (penicillinase producing)
Susceptibility Testing
- Diffusion Techniques
Quantitative methods that require measurement of zone diameters provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. One such standardized procedure1,2 that has been recommended for use with disks to test the susceptibility of microorganisms to dicloxacillin, uses the 1 mcg oxacillin disk. Interpretation involves correlation of the diameter obtained in the disk test with the minimum inhibitory concentration (MIC) for dicloxacillin.
Reports from the laboratory providing results of the standard single-disk susceptibility test with a 1 mcg oxacillin disk should be interpreted according to the criteria provided in Table 1.
- Dilution Techniques
Quantitative methods that are used to determine minimum inhibitory concentrations (MICs) provide reproducible estimates of the susceptibility of bacteria to antimicrobial compounds. One such standardized procedure1,3 uses a standardized dilution method (broth or agar) or equivalent with oxacillin powder. The MIC values obtained should be interpreted according to the criteria provided in Table 1.
