Karolina Gullsby

Karolina Gullsby is a Researcher at the Center for Clinical Research, Gävleborg, a collaborative entity between Region Gävleborg and Uppsala University. Her work bridges clinical practice and academic research in infectious disease diagnostics and epidemiology, with primary focus on bacterial and viral pathogen surveillance in Swedish populations.

Her research spans molecular epidemiology of respiratory pathogens (Mycoplasma pneumoniae, Bordetella pertussis), sexually transmitted infections (Chlamydia, Gonorrhea), and emerging viral threats including SARS-CoV-2. She specializes in developing and validating real-time PCR assays for pathogen detection and antimicrobial resistance monitoring, with emphasis on clinical applicability and public health impact. Her methodological expertise includes whole-genome sequencing, diagnostic test evaluation, and longitudinal surveillance studies.

Analysis of her publication record (2007-2025) reveals consistent focus on pathogen evolution, diagnostic innovation, and pandemic impacts. Recent work examines SARS-CoV-2 stool transmission in children (2025), neonatal E. coli genomics (2024), and pandemic disruptions to STI testing (2022). Her research demonstrates strong regional integration within Gävleborg and Uppsala counties, often leveraging national Swedish healthcare data for epidemiological insights.

As part of the Center for Clinical Research, Gävleborg, she operates within a multidisciplinary clinical-academic ecosystem that facilitates rapid translation of diagnostic findings into healthcare improvements. Her collaborations span Uppsala University, regional hospitals, and international research networks across Europe.
