What is it indicated for?
The MicroScan® MICroSTREP plus™ Panel is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media of aerobic streptococci, including Streptococcus pneumoniae. After inoculation, panels are incubated for 20 — 24 hours at 35°C +/- 1°C in a non-CO2 incubator, and read visually according to the Package Insert.
This particular submission is for the addition of the antimicrobial Tetracycline at concentrations of 0.06 to 16 mcg/ml to the test panel
The organisms which may be used for Tetracycline susceptibility testing in this panel are:
Streptococcus spp.
Streptococcus pneumoniae
