Ecology of host specificity in vector-borne parasites
Ekológia hostiteľskej špecifickosti vektormi prenášaných parazitov
Program: SRDA
Project leader: MVDr. Derdáková Markéta PhD.
Annotation:Emergence and spread of new infectious diseases is becoming a never more serious medical, societal and economical problem. Increasingly more diseases expand their ranges or re-emerge in areas from where they had been wiped out long ago. The emergence of new diseases is most frequently attributed to global environmental changes, including climate change, land use changes and changes in human concentration. A key role in the spread of new diseases is attributed to changed patterns of animal migration and therefore also of their parasites – potential vectors of diseases. Despite great effort, knowledge into the causes of the successful transmission and spread of vector-borne parasites is still only poorly understood. Consequently, theoretical prediction models of the spread of diseases and efforts to halt this spread are not effective. The aim of this project is to increase the understanding of the causes of host specifity and the regulation of circulation of vectorborne parasites. We will use two globally important study systems that involve tick-borne Borrelia spirochetes and insect-borne Plasmodium and Haemaproteus haemosporidians. The objective is to identify taxonomic, genetic and phylogenetic structure of local host associations and to assess if host specificity is a result of host specialization by parasites or i tis a result of host and vector ecology.

Of Sheep, Goats and Tick-borne Encephalitis virus
O ovciach, kozách a víruse kliešťovej encefalitídy
Program: SRDA
Project leader: MVDr. Derdáková Markéta PhD.
Annotation:Emerging tick-borne encephalitis from May this year in eastern Slovakia, has been the largest in number of cases for the last five years. As usual, it was supposed that products from raw sheep's milk had been the causative agens. Such enormous epidemic is striking due to the regular routine screening of sheep milk. We have known many foodborne infections from history, but most of cases was related to goat's milk. The aim of the proposed project is a comparative analysis involving sheep respectively goats foodborne infections. With regard to exact criteria it will be selected a representative number of farms from all Slovakia. We will investigate the milk of sheep and goats, as well as ticks collected from direct observation of the animals. It will be done for each farm. Sample will be examined by highly sensitive molecular biological methods for the virus presence. From animal blood we evaluated the serological status of all investigated animals. Evaluation of the results we can see how engaged sheep and goats in the case of food-borne infections. In the case of virus positive samples by sequencing analysis we obtain very valuable information about the genetic diversity of the TBEV in our country. An equally important outcome of the project will be specific methodological recommendations for farmers in terms of preventing foodborne disease.

Oribatid mite communities of urban ecosystems
Oribatocenózy urbánneho prostredia
Program: VEGA
Project leader: Mgr. Mangová Barbara PhD.
Annotation:The human impact on ecosystems and communities of different organisms is highly actual topic. Mankind is changing its environment continuously and is adapting it to its needs without any regard to other biota. By indirect impact we often unknowingly decrease diversity of all communities (as plants as animal). This way also communities of small soil arthropods are affected that play a serious role in nutrient cycling due to cutting of fallen leafs. This project will be focused on oribatid mite communities in urban habitats and other biotops affected by human impact. Oribatids are soil mites and for their communities it typical high diversity in natural ecosystems. This diversity decreases withincreasing human impact and it also changes species composition of the community. Using structure of orbatid mites community we want to define differences between different ways how to care for “green parts” of the city.

Reproductive strategies and relation to acoustics and migration: case studies on Reed Warbler and Lesser Grey Shrike
Reprodukčné stratégie vo vzťahu k akustickým parametrom a migračným stratégiám: štúdie na trsteniarikovi bahennom (Acrocephalus scirpaceus) a strakošovi kolesárovi (Lanius minor).
Program: VEGA
Project leader: RNDr. Darolová Alžbeta CSc.
Annotation:Song of passerines have several functions, like territory defense and mate attraction. By using of reproduced song of higher and lower quality in the Reed Warbler we will simulate occupied territories by males of different quality. We will determine the male strategy of territory choice affected by simulating quality of neighbor song, the female mate choice in relation to quality of neighbor song and evaluate the maternal investment of females into eggs in terms of clutch size, egg yolk testosterone and egg white lysozyme, in dependence on quality of neighbor song. Long-distance migrant songbirds are among the most endangered species. Their migration strategies are almost unknown and their relation to reproductive strategy, population trend and endangering factors is being not explained sufficiently. Using geolocators we will study the migration strategies and routes of selected individuals of the Lesser Grey Shrike and analyze their breeding success as well local and global factors of endangerement.

The role of neuropeptides and their receptors in regulation of endocrine and reproductive organs in the silkworm (Bombyx mori)
Úloha neuropeptidov a ich receptorov pri regulácii aktivity endokrinných a reprodukčných orgánov priadky morušovej (Bombyx mori)
Program: SRDA
Project leader: Ing. Roller Ladislav PhD.
Annotation:Insects are widespread and evolutionary extremely successful group of animals that show unique adaptations during development and reproduction. These adaptations are mediated by special endocrine glands including corpora allata (CA) that produce juvenile hormones (JH) and various modifications of reproductive organs. These important organs are under control of regulatory compounds that include neuropeptides produced by neurons and endocrine cells. However, neuroendocrine processes controlling activity of the CA in different developmental stages are not fully understood. Our preliminary and published data indicate that JH production from the CA is controlled by several peptidergic cells, whose specific functions in this process remain to be determined. Likewise, the role of neuropeptides during mating, fertilization and egg laying is not fully understood. Therefore, in this project we will identify neuropeptides, receptors and peptidergic cells involved in regulation of the CA and reproductive organs in the silkworm Bombyx mori. We will analyze neurons directly innervating these organs, as well as endocrine Inka cells that may control these organs via humoral pathways. We will employ techniques of molecular biology and immunohistochemistry to identify signaling molecules and peptidergic cells, while transgenic approaches in combination with physiological and behavioral assays will be used to determine roles of specific neuropeptides and their receptors. Expected results are important for understanding of molecular mechanisms underlying regulation of development and reproduction, which require complex neuroendocrine communication between peripheral organs and CNS.

The role of ectoparasite-ectoparasite interactions in the transmission of vector-borne parasites
Význam interakcií medzi ektoparazitmi pre prenos vektormi-prenášaných patogénov
Program: VEGA
Project leader: Mgr. Václav Radovan PhD.
Annotation:One of the biggest challenges faced by ecologists is to understand how and to what extent interspecific interactions within and between different guilds influence community structure, abundance of specific species or biodiversity of organisms of interest such as pathogens. In spite of a general acceptance of the existence of such a complex system, most ecological interactions are studied in relative isolation. The goal of this project is to see how the interactions between a certain host and a certain vector-borne parasite are affected by the complexity of ectoparasite-ectoparasite interactions. We specifically aim to establish if the interactions among multiple blood-feeding dipteran ectoparasites can influence the susceptibility of an avian host to some of the ectoparasites and/or pathogens that they vector. Namely, we plan to reveal if host susceptibility to haemosporidians can be mediated by 1) ectoparasite-ectoparasite interference or 2) modulation of host immunity by background ectoparasite pressure.
