In a bumper episode, Kristin talks with ID physician and clinical microbiologist with Westmead Hospital and the Institute Of Clinical Pathology And Medical Research (ICPMR) Dr Indy Sandaradura.

They discuss all things clinical microbiology, from how tests are run to how microbiologists decide what to report, in terms of sensitivities and positive results.

Indy helps us understand why we still do Gram staining, first developed by Danish scientist Hans Christian Gram in 1884.
