Plasmid-mediated horizontal gene transfer is considered a major driving force for rapid bacterial adaptation and diversification. Identification of unknown or known plasmids was once difficult due to repeat regions. CD Genomics employs next generation sequencing (NGS) or long-read sequencing technology to accurately obtain all genomic knowledge of plasmid. Coupled with powerful bioinformatics algorithms and tools, we can help you identify antibiotic resistance genes (ARGs), mobile genetic elements and any other genes of interest.

Plasmids are small and circular pieces of DNA presenting in bacteria (like Escherichia coli) or other organisms. It can replicate independently from the host genome. Plasmids are important vehicles for rapid adaptation of microbial populations to environmental changes. Plasmid-mediated gene transfer is very important in the dissemination of ARGs. Plasmids are transmissible between host cells, leading to the quick spread of their accessory genes within a bacterial community. The Food Safety Authority (EFSA or FDA) requires critical information of plasmids in food or feed industry, mainly because of the transmission of antibiotic resistance traits. CD Genomics developed a unique and sequencing-based platform to help researchers quickly identify and characterize plasmids.
NGS and long-read sequencing technologies offer a strong potential for plasmid identification, diversity, characterization and evolution studies. Based on Illumina HiSeq, PacBio or Oxford nanopore sequencing platforms, we are dedicated to offering full-length plasmid sequencing service, to detect and identify plasmids. Long-read sequencing can span complex repetitive regions to ensure complete and accurate sequence data. We help you discover mobile genetic elements, screen ARGs, annotate other accessory genes. Good annotation of plasmid genomes is necessary to maximize the value of the rapidly increasing volume of bacterial strains. These informations are very important to ensure food safety & quality and control antimicrobial resistance.
