Haemoproteus in passerines: Prevalence and infekction dynamics
Chalupová, Barbora ; Svobodová, Milena (advisor) ; Munclinger, Pavel (referee)
The genera Haemoproteus and Plasmodium are widespread genera of blood parasites from phylum Apicomplexa. Both genera have dixenous life cycle and their definitive hosts belong to the order Diptera. Both parasites can be found in birds where asexual division takes place. The infection with genera Haemoproteus and Plasmodium is usually asymptomatic; during long lasting chronic phase relapses of the infection can occur. We gained 1 092 blood samples from 29 trapped species of passerines in Milovice forest during seasons 2017-2019. Haemosporidians were detected in 48 % of samples. The prevalence of genus Plasmodium was 16 %, the prevalence of genus Haemoproteus was 22 % and 10 % we could not specify the parasite. We have found six new lineages of genus Haemoproteus, provisionally named Haemoproteus lineages coccoc_1, coccoc_2, coccoc_3, coccoc_4, embcit, fricoe which total prevalence was 14 %. Lineage Haemoproteus sp. coccoc_1 was the most noticed one and its prevalence was 12 %. Plasmodium relictum clone Peng14-121Br2AF and isolate Cc_P1 was the second most prevalent (13 %). Infection dynamics was studied in samples gained in years 2014-2019. Forty individuals were examined between years and twenty-seven individuals were examined intraseasonally. Three individuals were trapped both intra- and...

The image of a violent woman
Chalupová, Barbora ; Klusáková, Veronika (advisor) ; ŘEZNÍČEK, Martin (referee)
In my bachelor´s thesis I deal with the ways of depicting of violence caused by female characters in the context of last year´s (2017) film fiction in the western culture. I´m describing particular instances of woman violence on the background of the tendencies of power and gender in the society. I´m dealing with strong female characters from several points of view, i.e. on the basis of the motivation for violence, sophistication of the characters and possible social impact regarding redefinition of attitudes towards the questions of gender. In conclusion I´m offering my own solution in the form of certain manifesto. I´m introducing my idea of overcoming the dilemma of an attempt of showing strong/violent and still credible characters, liberated from the burden of stereotypical anticipation.

Haemoproteus in passerines: infection dynamics at the individual level
Chalupová, Barbora ; Svobodová, Milena (advisor) ; Hořák, David (referee)
The genus Haemoproteus is worldwide distributed parasitic protist, which belongs to the phylum Apicomplexa. This blood parasite has dixenous life cycle and he is occurs in the bird's blood and in invertebrate vectors. Genus Haemoproteus is transmitted by blood-sucking vectors, biting midges (Ceratopogonidae) and hippoboscid flies (Hippoboscidae). Vectors are final hosts of the genus Haemoproteus and the sexual process takes place in these vectors. Birds are intermediate hosts, in which representatives of the genus Haemoproteus spend most of their lives. In this bachelor thesis I focused on the influence of the genus Haemoproteus on birds and I focus on the time, when the bird gets infected by Haemoproteus in his life. Key words: Haemoproteus, birds, infection, life cycle, host, Ceratopogonidae, Hippoboscidae
