Tobias Allander Group
Clinical Virology and Virus Discovery
The group is based at the Department of Clinical Microbiology at Karolinska University Hospital, and the research is focused on developing efficient diagnostic methods for virus infections. We have a special interest in respiratory tract infections, but also study gastroenteritis viruses and chronic virus infections.
A main activity is identification of unknown viruses and clinical characterization of newly discovered viruses. The group has identified two novel human viruses, human bocavirus (HBoV) and KI polyomavirus (KIPyV). We have further established a relationship between human bocavirus and acute respiratory disease in infants and children. HBoV analysis is now routinely provided to health care
Virus discovery is done by combining a specially designed virus purification protocol with high-throughput sequencing and bioinformatics, in collaboration with the genome sequencing group at the Department of Cell- and Molecular Biology, Karolinska Institutet. We screen a wide variety of clinical samples for unknown viruses, from upper respiratory tract secretions to tumors.
Virus infections impose a huge disease burden on humanity. Diagnosing infectious agents and searching for the cause for diseases with unknown aetiology is fundamental for many aspects of clinical medicine.
