	Elektrochemický biosensor pro deteci patogenních bakterií v potravinách Jankovský, Viktor The aim of the theoretical part of this work is to summarize vital pathogenic bacteria in the foodstuff, describe the essential characteristics of the chosen bacteria, the health consequences and the most-often used treatment. Next topic included in the theoretical part is treatise about not only the classical cultivational but also the modern technical methods used to detect bacteria. The last chapter discusses the essential electrochemical methods used in the practical experiment. The practical part is focused on the verification of the electrochemical biosensor functionality which is used for the detection of pathogenic bacteria. Special attention is paid to the cleaning of the gold electrodes, application of the thin thiol layer, activation of the surface, immobilization of the antibodies and bacteria and also to the electroche-mical-quantitative determination of the bacteria concentration. Considering that the bio-sensor construction represents a quite complicated experiment, it was necessary to em-phasize all the partial steps of the biosensor's construction so that it was possible to veri-fy the correctness of the procedure. The last step of the practical part is the analysis and interpretation of the results. Detailed record
	The interaction between stored product arthropods and pathogenic microorganisms causing hazard effect tot he consumers Wofková, Gabriela ; Hubert, Jan (advisor) ; Stejskal, Václav (referee) The ecological feeding interaction between arthropods and pathogens causes damage of stored plant commodities for human food and animal feed. This damage leads to loss of quality and quantity of stored products. The stored commodities are inhabited by microscopic fungi and various bacteria. These moulds are producing mycotoxins. The bacteria in stored products include human pathogens and also bacteria which are able to transfer the genes of antibiotic resistance. Fungivorous arthropods are able to distribute them to the new habitats and indirectly influence mycotoxin contained in stored food. They also disperse some bacteria of pathogenic influence on human or bacteria able to transfer genes of antibiotic resistance in stored plant commodities. The study summarizes possible risk effects of microbial and arthropods pest interaction to human. Detailed record
