Course Description: Laboratory professionals responsible for reporting microbiology culture results should be aware that Corynebacterium species and similar organisms recovered from clinical specimens have the potential to be pathogenic. This course provides an overview of some common Corynebacterium species that have been shown to cause human diseases, along with their primary sources and modes of infection. It highlights biochemical reactions, other testing methods for identification, susceptibility, and treatment options, as well as a brief overview of potentially pathogenic organisms that could be mistaken for Corynebacterium species.
