Trypanosomes from the T. theileri group in ungulates in the Czech Republic
Brotánková, Anna ; Brzoňová, Jana (advisor) ; Juránková, Jana (referee)
The Trypanosoma theileri group are blood parasites of ungulates. Confirmed vectors of these protists are horseflies or sheep keds for T. melophagium, but these trypanosomes were also detected in deer keds, mosquitoes and phlebotomus. We targeted on the investigation of possibility mosquitoes acting as vectors and additionally we targeted on the prevalence of T. theileri in mosquitoes at selected locations in the Czech Republic due to previous positive detection there. The measured prevalence has reached 6,4 % in mosquitoes, 4 % in deer keds and 16,7 % in sheep keds. The aim of experimental infections was to discover a potential of mosquitoes and phlebotomus acting as vectors of the T. theileri. Phlebotomus perniciosus and three species of mosquitoes Culex pipiens molestus, Culex pipiens quinquefasciatus and Aedes vexans were used for those experiments. Furthermore, isolates of T. theileri and T. melophagium from different sources were used. The divergence among these isolates and among used species of insect was found. The best results were achieved with Ae. aegypti and isolates from mosquitoes, where prevalence had reached 90,8 %. The infected mosquitoes were used for prediuresis research which had shown infection forms of the trypanosomes in the urine liquid. The phylogenetic analyse of T....

Trypanosomes of ungulates with emphasis on Europe
Brotánková, Anna ; Rádrová, Jana (advisor) ; Dvořák, Vít (referee)
Trypanosomes are veterinary and medically important parasites causing serious diseases and significant losses in livestock farming. Two subgenuses of trypanosomes were identified from ungulates in Europe. Trypanosoma evansi and T. equiperdum, flagellates of the subgenus Trypanozoon, could cause fatal infections to their hosts. Other Trypanosoma theileri, T. cervi, T. stefanskii, T. melophagium and T. theodori were discovered in European ungulates from the second subgenus Megatrypanum. These trypanosomes are common parasites in Europe, especially Trypanosoma theileri and T. cervi. On the other hand, T. evansi and T. equiperdum are occuring rather sporadically. Trypanosomes of the subgenus Megatrypanum are less significant because their lower medical and economical impact. They are generally apathogenic and so do not cause any clinical signs. Both morphological and phylogenetic informations of European trypanosomes are summarized in this work as well as details about their pathology, vectors and records of evidence in Europe.

Scenography of a musical theatre. Opera, composed by B. Martinu and G. Neveux, "Julietta" - a complex scenographic project
Brotánková, Anna ; DUŠEK, Jan (advisor) ; GLOGR, Karel (referee)
The goal of this thesis is to comparatively analyse, on theoretical level, Bohuslav Martinu?s manner of viewing musical work in connection with his scenical theatre pieces. Major focus is on composer?s notes and ponderings on then-common opera arrangements, and on the meaning of opera itself. The paper compares his style with contemporaneous tendencies of surrealistic avantgarde in scenography. Moreover, it addresses the portability of surrealistic principles onto stage, their dramatical potential, and different approach of leading czech representatives of surreal avantgarde towards this issue.
Second part of this thesis discusses and interprets opera Julietta (Snář / Dream Book), and investigates possibilities of its scenographic and costume arrangement.
