Antibiotic resistance has been discovered since the advent of antibiotics and has become more serious with the widespread use of antibiotics. Antibiotic resistance of microorganisms is a serious problem affecting human and animal health. Although, there are currently many regulations to limit the application of antibiotics in an attempt to control the resistance of microorganisms to antimicrobial drugs. However, these measures have had little effect. In order to quickly analyze the antibiotic resistance genes of common microorganisms, CD Genomics provides comprehensive antibiotic resistance gene (ARGs) detection solutions, including high-density gene detection technology based on DNA microarray (also called gene chip). Our DNA microarray antibiotic resistance gene detection service aims to provide customers with antibiotic resistance gene analysis for Staphylococcus aureus, coliform bacteria, Listeria, and other pathogenic bacteria.

At present, the detection of clinical microbial antibiotic resistance genes is based on phenotypic detection. Therefore, some silently expressed resistance genes may be overlooked. DNA microarray technology can prevent this from happening. Our DNA microarray platform is very cost-effective and designed for the identification of antibiotic resistance genes. And the limitation of non-specific cross-hybridization has been overcome, resulting in increased specificity. The platform can qualitatively or quantitatively measure the antibiotic resistance genes present in microorganisms through probes composed of several kb (cDNA chip) or dozens of (oligonucleotides) specific types of nucleotides. CD Genomics' DNA microarray platform is designed to detect genes resistant to all antibiotics such as β-lactams, chloramphenicol, bacitracin, aminoglycosides, macrolides, and sulfonamides.
CD Genomics, as a professional supplier of microbial antibiotic resistance gene detection, can provide you with a complete DNA microarray solution for the simultaneous analysis of hundreds of antibiotic resistance genes. We have only shown some antibiotic resistance targets in the table below. If you want to know more, please contact us directly.
