Antimicrobial Susceptibility - Staphylococcus
Also known as: MA STAPH
Use
The Antimicrobial Susceptibility test for Staphylococcus determines the in vitro susceptibility of Staphylococcus species to various antimicrobial agents. It's crucial for guiding the selection of effective antimicrobial therapy in patients infected with Staphylococcus spp., especially considering the variability in resistance patterns. This test is important for managing infections caused by Staphylococcus spp. by providing detailed susceptibility information to help tailor antibiotic regimens.

Limitations
The test does not identify the presence of the mecA gene directly. For detecting mecA gene, refer to the separate Antimicrobial Susceptibility - mecA Gene by PCR test. The test interpretations include terms such as susceptible, intermediate, or resistant, and are selective based on the organism and source. The absence of PBP2a indicates that mecA-mediated resistance was not detected, but it does not rule out the possibility of oxacillin resistance by other mechanisms. Therefore, this test should be used in conjunction with clinical findings and other diagnostic information.
