An early key to anti-infective development is to determine the spectrum of in vitro activity against relevant bacteria encountered in clinical settings across the world. Within the IHMA Bacterial Repository, we have a continuously expanding collection of current phenotypically and genotypically characterized bacterial pathogens. These organisms are catalogued according to geography, year of isolation, resistance phenotype, specimen source, patient demographics, healthcare location, and other parameters. The Repository can be used to rapidly assemble custom collections to profile the anti-bacterial activities of any products in your discovery pipeline.
