Malaria and other haemosporidian parasites (Haemosporida) are widespread, and some species cause diseases in vertebrates, including humans. Many recent studies addressed avian haemosporidians worldwide. Parasitemia of these parasites markedly correlates with the seasons of the year, being relatively high during the period of active transmission (spring-summer) and low (chronic) when transmission decreases (autumn) probably due to the lowering of activity of dipteran vectors in Europe. Molecular studies show that European birds are infected and transport northern-origin parasite lineages to tropical regions where, however, they are not transmitted. This might be due to a decrease of viability of gametocytes during the chronic infection stage. There is no research on this subject, and it is unclear if viability of haemosporidian gametocytes changes in parallel with the parasitemia decrease in autumn. Our hypothesis is that viability of gametocytes decreases in autumn, indicating that migrating birds transport epidemiologically impotent parasites to wintering grounds, but a contrary situation occurs in spring when gametocytes of high potency are transported to bird breeding grounds in spring. The objective of this project is to test this hypothesis experimentally. To reach this goal, the sexual process of same Haemoproteus species (sister genus to malaria parasites) will be studied in vitro and in vivo. Bird blood with mature gametocytes will be collected and ability of ookinete development in vitro as well as experimental infections with laboratory-reared biting midges Culicoides nubeculosus will be carried out. The development patterns of these pathogens will be investigated combining molecular and microscopic protocols. We plan to obtain first data about the patency of haemosporidian gametocytes in different seasons of the year. This information will contribute to a better understanding of haemosporidiosis epidemiology and might be used for the development of disease preventive measures.
