Students' knowledge of upper primary school about diseases transmitted by ticks
Michálková, Pavla ; Hanušová, Jaroslava (advisor) ; Thorovská, Alena (referee)
The main research problem concerns the characteristics of tick-borne disease and determine the quantity and quality of information that students get in health education and biology of these diseases. The theoretical part deals with the history, etiology, clinical features, diagnosis, treatment and prevention of tick-borne encephalitis and Lyme disease. It also discusses the general problems of tick and other diseases that ticks carry and cause. Also is mentioned the inclusion of tick-borne diseases in the educational program. The practical part is devoted to the awareness of upper primary school students and changes in their knowledge about the issue during their elementary education. The aim of this thesis is to determine how the students are informed about diseases transmitted by ticks, especially about Lyme disease and tick-borne encephalitis. This method is used questionnaire, which includes questions regarding this issue. Although the results of the research show a certain degree of knowledge of students at upper primary school, especially in some classes is unsatisfactory. Based on research, there is provided a recommendation for pedagogical practices. KEYWORDS: tick, tick-borne encephalitis, Lyme disease, knowledge, disease, upper primary school

Analýza invazivní schopnosti a infekčního potenciálu nově popsaných druhů borelie z komplexu \kur{Borrelia burgdorferi} sensu lato, \kur{B. americana} a \kur{B. carolinensis} na laboratoním modelu infikovaných savců
ŠOLCOVÁ, Lucie
The aim of the study was to analyze the infectious potential of the newly described species, B. americana and B. carolinensis, studied on the laboratory model mammals mice. Our goal was to analyze and compare the vectorial capacity of two different tick vectors, Amblyomma americanum and Ixodes ricinus, in acquiring and transmition of both spirochete species to the host. The results of this study confirmed that ticks A. americanum and I. ricinus are capable to maintain and transmit B. americana and B.carolinensis.We confirmed that both analysed spirochete species, B. carolinensis and B. americana, showed the potential to develop the disease in laboratory model mammal, which indirectly support the fact that both spirochete species might be concidered as the risk factors in the area where they are distributed. Our results shows that A. americanum is able to transmit both spirochete species, which increases that risk of acquiring the Lyme disease to human population in the area of distribution of A. americanum

Serological diagnosis of borreliosis deseases
Sližová, Ivana ; Chmelař,, Dittmar (referee) ; Lochman,, Ivo (advisor)
The aim of present master’s thesis was to compare the results of serological methods for diagnosing borreliosis that are commonly used in Spadia laboratories (ELISA, immunoblots) in terms of recommendation on how and when to indicate and interpret them. The theoretical part is focusing on the characteristics and history of borreliosis, microbiological description of Borrelia, immune system and pathogenesis of the disease as well as the therapy and prevention. The experimental part is focusing on the analysis of results obtained from common examinations of antibodies to Borrelia made in Spadia Lab laboratories from January 1st 2014 to December 31st 2015. Screening of antibodies to Borrelia made by ELISA in IgM and IgG was done for all samples according to recommendation of CDC. In 2014 the ELISA screening was done using ELISA kits from Euroimmun and Evolis sample processors whereas in 2015 it was done using DiaSorin’s CLIA kits on Liaison analyser. Positive results were then confirmed by Westernblot or lineblot alternatively if the physician did not ask otherwise. It must be remembered that ELISA and Westernblot belong among serological methods that are using antibodies, i.e. substances produced by the immune system. The immune system plays the key role in protecting the body against infection and the antibodies are its important tool. Serological methods belong among immunoassay methods, which is still not standardized. Diagnosis of infections cann‘t be based only on antibody testing. It is necessary to assess the results in the context of the entire clinical picture, history and in the case of antibodies it is recommended retesting with an interval.

Sensitivity of spirochetes from \kur{Borrelia burgdorferi} sensu lato complex to human complement: infection potential of selected species
TICHÁ, Lucie
Sensitivity of spirochetes from Borrelia burgdorferi sensu lato complex to serum complement of humans of different age and sex was analyzed. Complement-mediated Borrelia killing was observed in different combination of serum and selected Borrelia genospecies. The obtained results confirmed that age itself does not influence the sensitivity of human to Borrelia infection. However, the females seem to be more vulnerable to it. Each of ten tested Borrelia species was proved to be potentially infective for human in different ratio. The clear separation of all ten checked Borrelia species into two groups was revealed after the reaction with human sera: species with low sensitivity to human serum complement (mortality below 1 percent) and species with higher sensitivity (mortality over 3-4 percent).

Preparation of monoclonal antibodies against Borrelia
ŠVEJDOVÁ, Veronika
In my bachelor thesis I deal with preparation of monoclonal antibodies against antigens of Borrelia. In theoretical section I describe genus Borrelia and antibodies. The introduction deals with the history of discovery of the spirochete that causes Lyme disease, vectors of this disease and classification of Borreliae according to geographical occurrence. Taxonomic categorization and description of the bacterium followers. It is focused on flagellum, arrangement of genetic material and on external surface antigens important for this bacterium. In the next section I describe Borrelia vector - host interactions and the development of immune response during the disease. Dermal symptoms of the Lyme disease are described in detail. A few words about relaxing fever are added. This chapter ends with description of laboratory diagnostics of Borrelia burgdorferi. Next, I focused on the characterization of antibodies and on preparation of monoclonal antibodies by hybridoma technology. I briefly describe ways of their utilization. Practical part of Bachelor thesis was carried out in the laboratories of Faculty of Science. Here, with the help of hybridoma technology, I fused myeloma cells with splenocytes of immunized mice producing hybridomas. These hybridomas I cultivated in medium, which I subsequently tested for occurrence of antibodies by ELISA. Hybridomas having high productivity were cloned, frozen and stored in liquid nitrogen. Finally I purified monoclonal antibodies, concentrated them and tested their titre.

Flagellin and outer surface proteins from Borrelia burgdorferi are not glycosylated
ŠTĚRBA, Ján
Glycosylation of four proteins from Borrelia burgdorferi s.s. was investigated ? flagellins FlaA, FlaB, and outer surface proteins OspA and OspB. Glycosylation of these four proteins was not proved by any of the used techniques. However, other glycan-staining positive proteins were present in the borrelia samples. These proteins were suggested to originate in the culture medium.

THE LEVEL OF AWARENESS AND ATTITUDES OF ČESKÉ BUDĚJOVICE FAMILIES TOWARDS QUESTIONS OF TICK-BORNE DISEASES
LANGEROVÁ, Dagmar
Bachelor´s work deals with the questions of 2 most frequent tick - borne diseases in the Central Europe - Tick Borne Encephalitis and Lyme Disease. The purpose of my work is to survey the awareness of České Budějovice families about these diseases and possibilities of their prevention. For the primary data collection the technique of questionnaire has been chosen. As the target group pupils of higher classes of basic schools and their parents have been chosen. From 110 distributed sets of questionnaires only 63 have been processed. After the evaluation of these questionnaires, both my hypotheses have been disproved. The awareness of parents was better than the awareness of pupils, but the difference was very small. České Budějovice families know that the risk of Tick Borne Encephalitis in the region of South Bohemia is higher than in other regions in our country. The level of awareness of České Budějovice families about questions of tick {--} borne diseases is quite good.
