Phenotypic and Genotypic Characterization of Antimicrobial-Resistant (AMR) Strains from the ATCC^® Collection

Antimicrobial resistance (AMR) is a global health crisis recognized by the WHO Priority Pathogens List, which identifies critical threats such as carbapenem-resistant Acinetobacter baumannii and Candida auris. Trichophyton indotineae is an emerging fungal pathogen that has recently been isolated in the US. These pathogens pose significant challenges for treatment and infection control. To accelerate the development of diagnostics and therapeutics, researchers need access to standardized, well-characterized strains. ATCC addresses this need by providing a curated collection of bacterial and fungal AMR strains, each extensively characterized both phenotypically and genotypically. Strains include minimum inhibitory concentration (MIC) values, susceptibility profiles, and whole-genome sequencing (WGS) data generated using Illumina and Oxford Nanopore platforms for high accuracy and depth. Annotated genomes and methylation data are available through the ATCC Genome Portal (genomes.atcc.org). By bridging genomic insights with clinical applications, ATCC empowers global efforts to combat AMR and supports innovation in antifungal and antibacterial research.
