Genetic Method Testing Service

Antimicrobial susceptibility testing (AST) is the measurement of the susceptibility of bacteria to antibiotics. It is used because bacteria may have resistance to some antibiotics. Considerable advances have been made in the AST which can be divided into two categories: phenotypic methods and genetic methods.

With the continuous progress of the world's biomedical industry and the gradual update of detection technology, genetic method or nucleic acid methods shines with its advantages such as accurate quantitative analysis and short operating procedures comparing the qualitative ADD method and the semiquantitative MIC method.

Creative BioMart Microbe provides many kinds of genetic methods assay services to detect whether bacteria possess genes which confer antibiotic resistance (including but not limited to):

• Polymerase chain reaction (PCR)
• Real-time quantitative PCR(RT-qPCR)
• DNA microarray
• DNA chips
• RNA markers
• Loop-mediated isothermal amplification (LAMP)

The genetic tests provided by Creative BioMart Microbe incorporate nucleic acid techniques similar to those used for organism identification but modified to detect known resistance genes or mutations, such as the imipenem, colistin, ciprofloxacin and the most classic gene, mecA, a gene for oxacillin resistance in S. Aureus, which is considered resistant to most beta-lactam drugs regardless of apparent susceptibility results. In addition, Creative BioMart Microbe also provides a variety of methods including electrophoresis, southern blotting, and other DNA sequencing analysis methods to demonstrate the presence of the genes.
