Seroprevalence of anti-Yersinia antibodies in healthy Austrians

European Journal of Epidemiology

Yersiniosis is caused by Y. enterocolitica and Y. pseudotuberculosis mostly presenting as intestinal infection. The infection is usually acquired from contaminated food. The aim of this study was to determine the seroprevalence of anti-Yersinia antibodies in Austrians. Sera of 750 healthy Austrians from all nine states were tested for anti-Yersinia IgG antibodies using the recomBlot Yersinia Westernblot kit. Overall seroprevalence was 29.7%. Seroprevalence increased significantly with age from 24.7% in the group of the 19 to 24 year olds to 38.5% in the group of persons older than 44 years. The seroprevalence of anti-Yersinia antibodies varied within the states between 18% and 43.5%. The high seroprevalence of anti-Yersinia antibodies in contrast to only approximately 100 reported yersiniosis cases per year points to the fact that the majority of infections is either subclinical or mild.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
