Discordant Carbapenem Susceptibility in Methylobacterium Species and Its Application as a Method for Phenotypic Identification

We encountered a meropenem-resistant, imipenem-susceptible clinical Methylobacterium isolate and sought to determine if discordant carbapenem susceptibility (meropenem resistance/imipenem susceptibility) was common among different Methylobacterium species. We concurrently investigated whether this
