Abstract

All viral genomes, including the SARS-CoV-2 virus, mutate over time, and some of these mutations can affect the characteristics of the virus, such as the ease of spread, the severity of the patient's clinical picture, or the effect of vaccines, therapeutic drugs, diagnostic tools or other measures of public health and social protection. Because of all the above, it is imperative to carry out continuous sequencing of this pathogen. The main goal of this research was to obtain the highest quality genomic sequences of the SARS-CoV-2 virus, to compare the obtained sequences with the reference Wuhan-Hu-1 sequence and to obtain a high-quality genomic alignment in order to reconstruct the appropriate phylogenetic tree. For the purposes of this research, a next-generation semiconductor sequencing method was chosen. In this research, a total of 47 samples of nasopharyngeal and oropharyngeal swabs from patients from the human population of Bosnia and Herzegovina with a clinical diagnosis of COVID-19 were collected. In the processed 47 samples, there are several monophyletic groups on the constructed phylogenetic tree, of which one sample belongs to the same monophyletic group as the Wuhan-Hu-1 reference sequence. The greater number of samples is needed for a more comprehensive approach. Therefore, the results of this research can act as a guideline for the design of effective measures and strategies in order to solve problems regarding future pandemics as efficiently as possible.
