Residual Antimicrobial Activity
ALIFAX RESIDUAL ANTIMICROBIAL ACTIVITY TEST
The Alfred 60 and HB&L systems perform the RAA test and bacterial culture simultaneously. Using Staphylococcus epidermidis as a growth control it is possible to check for the presence of antibiotics and drugs or foods with antibacterial properties that inhibit bacterial growth in a sample. Bacterial culture the native sample is inoculated at the same time into a vial containing a Staphylococcus epidermidis suspension which is sensitive to most of the commonly used antibiotics. The systems allow the determination of Residual Antibiotic Activity in the sample by comparing the Staphylococcus epidermidis with the bacterial culture growth curves. The Alifax RAA test is also useful to monitor the effectiveness of therapy and verify if the antibiotic has reached the infection site. RAA test results are simultaneously displayed with bacterial growth results in Urine and Human Biological Liquid cultures.
