- Detection viral DNA of B19, HBoV and hPARV4 in study cohort using various polymerase chain reaction (PCR) techniques;
- Development of highly specific and sensitive monoclonal antibodies (mAbs) by virus like particles (VLPs);
- Development of highly positive predictive value (PPV) serological examination tools;
- Detection of IgM and IgG types of antibodies and antigen immunoexpression by using serological examination tools and mAbs;
- The complete analysis of viral gene characteristic and evolution phylodynamics;
- Organization of workshops, seminars, reporting at local/international congresses and conferences, preparation of scientific publications;
- Preparing master and doctoral works within the frame of project.
Workshop in Vilnius, 27th-28th of September, 2017
Research team members from all three countries participating in the project realisation have met in Vilnius (Lithuania) on September 27–28, 2017, where presentations of preliminary results and reports on the progress of development of methods according to the tasks for the first project year were done.
