Abstract:
Telavancin was evaluated against S. aureus isolates with reduced susceptibility to other antimicrobial agents using two broth microdilution methods and Etest® strips. The three methods provided comparable results. Differences in telavancin susceptibility versus non-susceptibility were noted mainly in the VISA-daptomycin non-susceptible group of isolates. In this group the percent susceptibility was 38% for the Etest® method and 50% and 54% for the 2 broth microdilution methods. All differences in susceptibility were within one 2-fold dilution.

Magnetic Susceptibility and Permeability
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...
