Let's Talk Micro

In this episode of Let's Talk Micro, we continue exploring the tools that aid in the identification of gram-positive cocci. Tune in as we discuss the optochin disk, used to help identify Streptococcus pneumoniae, and the Microdase disk test, which supports the identification of Micrococcus species. These simple yet powerful tests remain essential in the clinical microbiology lab.
