Unveiling the Virulent Genotype and Unusual Biochemical Behavior of Escherichia coli ST59

Abstract

The use of selective and differential media is a rule that guides presumptive bacterial identification based on specific metabolic traits that are specific to each bacterial species. When a bacterial specimen displays an unusual phenotype in these media, this characteristic may lead to bacterial misidentification or a significant delay in its identification, putting a patient at risk depending on the infection type.
