Influence of second and third generation sequencers on cgMLST analysis of closely-related bacterial strains.
Slavíček, David ; Sedlář, Karel (referee) ; Nykrýnová, Markéta (advisor)
This bachelor thesis is about influence of sequncers of second and third generationon cgMLST analysis of bacterial genome. In the theoretical section were described selected sequencers of second and third generation and genome assembly principles. In the practical part were assembled six genomes of Klebsiella pneumoniae bacteria from University Hospital Brno. The genomes were sequenced each on two different sequencers, Illumina Miseq and Oxford Nanopore Technologies Minion. The genomes were assembled. Suitable genes were selected and insufficient quality genomes removed for the cgMLST analysis. The cgMLST analysis was performed and the results are shownin graphs.

Properties of current signals in nanopore sequencing
Plocková, Veronika ; Nykrýnová, Markéta (referee) ; Sedlář, Karel (advisor)
Oxford Nanopore technologies brought new and revolutionary technology in the field of DNA sequencing. Their sequencing device measures changes in the electric current flowing through pores together with DNA. This work aims to describe differences between raw signals produced by various sequencing kits and sequencing flowcells while sequencing several different bacteria. Two datasets combining five different organisms, two sequencing kits, and two types of flowcells were used to analyze various statistical parameters that would be suitable for the description of current signals gathered from nanopores. Finally, the samples were classified using the k-means algorithm and the results were discussed.
