Molecular characterization of Grapevine Pinot gris virus in Poland
Pieczonka, Karolina Katarzyna
Samples of different varieties grapevine from Małopolska and Podkarpacie collected on spring 2016 were tested for Grapevine Pinot gris virus (GPGV) by RT-PCR. 16 out of 65 plants were found positive for GPGV. Two set of primers were used for detection, targeting partial movement protein and coat protein, and RdRp domain, both of those regions were sequenced. Phylogenetic analyses settled the Polish isolates to described before asymptotic group. Also GPGV positive samples were tested by multiplex and simplex RT- PCR for multiple infections, and 18,5% of all samples were GPGV and GFkV positive. This was first survey of GPGV in Poland.

Evolution of host specificity in avian influenza
Divín, Daniel ; Vinkler, Michal (advisor) ; Horníková, Lenka (referee)
Avian influenza is a dangerous viral disease, which threats animals and people's health and nowadays evokes great concerns linked with pandemic threat. Veterinary procedures tries to limit spreading of infection by eradication of all birds nearby the outbreak place of the disease to limit as much economic damage as possible. However, there is obvious considerable variability in susceptibility, course and transmission of the disease in different species. In model species (Anas platyrhynchos f. domestica a Gallus gallus f. domestica), we can see a big difference in course of the disease linked with different equipment of immunity genes. There is fragmented information about other species. The main aim is therefore to summarize knowledge about avian influenza, it's origin, evolution, diversity, spreading in environment and susceptibility of different species to this disease.
