qPCR, nested PCR, and the search for bacterial serotypes
Episode 12
Wednesday, 15 July, 2026
Some science stories start with a textbook. Donna Paznar’s started with a tick. In this episode of Absolute Gene-ius, Donna Paznar, head of Molecular Infection Diagnostics at the Medical University of Vienna, discusses her work studying Streptococcus pneumoniae and its impact across the Austrian population. She explains why this respiratory bacterium can be especially dangerous for infants and older adults, how children may act as asymptomatic reservoirs, and why tracking more than 100 bacterial serotypes is both important and technically challenging. Donna also walks through the molecular methods behind her work, including qPCR for identifying positive samples, nested PCR for targeting more specific DNA regions, and sequencing to help confirm serotypes. Along the way, she highlights the complexity of surveillance research and the goal of developing more efficient multiplex qPCR approaches. The career corner takes a fun turn into ticks, workplace cliques, qPCR mistakes, and a proud sleuthing moment involving a rare tick-borne pathogen. Donna’s advice is simple and useful: try opportunities, expect failure, and stay open-minded. Visit the Absolute Gene-ius page to learn more about the guests, the hosts, and the science we explore.
