Parasites And Their Preparation For School Utilization
Chlumová, Kateřina ; Říhová, Dagmar (advisor) ; Hanel, Lubomír (referee)
This diploma thesis deals with common parasites of game animals, animals and human occurring in the territory of the Czech Republic. It focuses on their fixation and general preparation of such specimens for usage in teaching of Science. The first part is devoted to the phenomenon of parasitism, and the history and definition of this concept. Systematic hierarchy of various unrelated parasitic groups is clarified. The second part provides the list of parasites, from the evolutionary original to the highly derived groups. We give an overview of their morphology and anatomy with the emphasis on their life cycle. The detailed knowledge of life cycle is essential for obtaining specimens. In each group, we indicate methods of collection and fixation in detail. The co called smartmicroscope represent the main point of the third part of proposed diploma thesis. Text of the thesis is supplemented with pictures taken by smart microscope, as well as by common microscope. KEY WORDS parasite, parasitism, mikropredatore, vector, fixation, preparation, smart mikroscope

The role of trehalose in mycorrhizal associations
Šoch, Jan ; Ponert, Jan (advisor) ; Hála, Michal (referee)
Mycorrhizal symbiosis is a widely spread phenomenon in nature. A translocation of nutrients occurs between symbionts with disaccharide trehalose playing a key role in the process. However, this saccharide fulfils many important roles in metabolism of fungi and plants. Fungi use trehalose mainly as storage and transport saccharide. On the other hand, trehalose occurs in extremely low amounts in plants where it acts as a signal molecule. Thus it is likely that the saccharide could be used by the fungus to manipulate plant metabolism on a physical interface between symbionts. Trehalose has a similar function in many parasitic interactions. In most cases of mycorrhizal associations trehalose synthesis creates a carbon sink in mycelium which leads to saccharide transfer from the host plant to the fungus. Completely different situation occurs in the types of mycorrhizal symbiosis, where saccharides are translocated from a fungus to a plant. Some plants can utilize trehalose effectively as a sole source of energy. Consequently, the question raises - could such plants gain fungal trehalose on purpose as a source of energy and carbon? This review aims to assess and discuss the mentioned possibilities considering available literature. Key words: mycorrhiza, orchids, parazitism, saccharides, sink, symbiosis,...

Teaching of parasitism in elementary and secondary schools
Čiháková, Kateřina ; Mourek, Jan (advisor) ; Ehler, Edvard (referee)
Main aim of this master thesis is to map the situation of parasitism teaching in elementary and grammar schools. Thats why it contains analysis of reachable elementary and grammar school textbooks - it informs about various kinds of rating the textbooks, which can help both - current and future teachers of biology - to better know and identify reachable textbooks and choose the right ones for the parasitism teaching. It also contains test results of students parasitism knowledge, which are generally very good. Anyway they should learn much more about parazite's manipulation of their host behavior. Other part of my master thesis shows the results of grammar school teachers-filled questionnaires. All questionnaire results (teachers' and students') show that there can be an improvement in parasitism teaching. In next section you can find the Framework Education Programme analysis, own educational programme draft - workbooks, didactic games and powerpoint presentations. Thanks to the realization of teaching the parazites manipulation of their host behavior I found out that students' interest in the topic is quite big so it would be a shame not to share this newly explored area of parasitism with them. Key words: parasite, host, manipulation hypothesis, questionnaires, parasitism teaching

The use of fungi and their products in organic farming
Krupičková, Karolína ; Dvořák, Petr (advisor) ; Král, Martin (referee)
Current excessive use of chemicals in plant protection raises problems. Two of these problems are increased resistance of pest populations and penetration of residues of these substances in the food chain. In recent years, there is an effort to reduce the use of chemicals and replace them with biological products that are friendly to the environment.
This thesis deals with the possibility of using of fungi and preparations containing them to protect plants, instead of using chemicals. This bachelor thesis summarizes literature and studies dealing with this problem. Firstly, it deals with mycoparasitic and entomophatogenic fungi. It mentions their representatives, which are important for biological plant protection. For mycoparzitic fungi are representatives Trichoderma harzianum, Clonostachysrosea and Pythium oligandrum. There are mentioned their life cycles and bio-preparations made from them, which are used for plants protection. From entomopathogenic fungi thesis deals mainly about genera Beauveria, Hirsutella, Lecanicillium, Metarhizium, Nomuraea, Paecilomyces, Tolypocladium and Aschersonia. Beauveria, Hirsutella, Lecanicillium, Metarhizium, Nomuraea, Paecilomyces, Tolypocladium and Aschersonia. For all representatives are listed bio-preparations and their use for protecting crops against pathogens. In the bachelor thesis are mentioned products based on fungi for protecting potatoes. Most of these products are not registered in the Czech Republic, except Polyversum which contains spores of Pythium oligandrum and is used to protect the potatoes against potato late blight (Phytophthora infestans).
The majority of biological products is highly effective against crops diseases, but some biological products are effective only in laboratory conditions at optimum conditions for the given species (eg. Tolypocladium cylindrosporum).

Nucleotide variability in \kur{enol-1} gene of entomopathogenic nematodes \kur{Heterorhabditis bacteriophora} and \kur{Steinernema feltiae}
HEJNÍČKOVÁ, Martina
The topic of this bachelor thesis is enol-1, parasitism-related gene in entomopathogenic nematodes. First part of this thesis deals with pattern of the enol-1 nucleotide variability. Nucleotide sequence of enol-1 was obtained from 9 strains of Heterorhabditis bacteriophora and 8 strains of Steinernema feltiae. I characterised and compared its structure and nucleotide variability. Phylogenetic analysis of enol-1 was done with closely related nematode coding sequences, acquired from internet databases. The second part of this thesis is devoted to virulence testing. Larvae of Galleria mellonella were infected with different strains of entomopathogenic nematodes, and their mortality was summarized.

Economic affectivity of health insurance analysis with view to payment of sickness benefits
Paikertová, Sylvie ; Chytilová, Helena (advisor) ; Svoboda, Miroslav (referee)
The aim of my thesis is to calculate expenses and returns brought by the health insurance transformation in the Czech Republic. In particular, economic and social impact due to the change in health insurance payments. The author firstly focuses on implementation of particular economic models in the frame of given and on the characteristics of the health insurance in historical context. The economical theories dealing with analysis of the markets with asymmetric information including its solution through insurance are going to be applied for a chosen topic. Due to the connection with these facts, the main acquisitions of american economists Akerlof, Spence a Stiglitz will be mentioned. Their works solving these problems, were the source. Analytical part concentrates on evaluation of acquired statistical data, concerning the number of sickness absence during the time before and after the reform. Correlation in context of change in health insurance payments will be found. Further, significance of a transition to solidarity principle and effectiveness of shift in government competencies directly to employers in ensuring health insurance payments will be assessed. The research is going to be done like a complement of the analytical part. Main goal of research is, after evaluating relevant data, give a proper insight about influence of a reform on companies. During the work with the data an analytical and quantitative method will be applied. According to the results obtained in practical part, possible alternatives of future development will be predicted. At the same time direct and indirect influence of the reform will be accented. The aim of the work will be evaluation of effectiveness of accepted methods in the reformed system of health care insurance.
