In this week’s installment of Medical Discovery News, UTMB’s Norbert Herzog and David Niesel discuss microbial fingerprints. “A person’s skin has over a thousand types of bacteria; and they differ significantly from person to person, depending on where on the skin you look. … This microbial fingerprint can be more reliable than an actual fingerprint since it’s not surface dependent — meaning, you can recover it from fabrics, for example.” MDN airs locally at 10 a.m. every Saturday on KUHF-FM.
