Abstract

The metagenomic approaches are one of the most sensitive tools to identify emerging viruses. With the emergence of the New Generation Sequencing (NGS) technologies, the software diversity used for data analysis has grown significantly. The bioinformatic analysis of the obtained NGS sequencing data represents still a significant challenge for the correct interpretation of the data due to the variability of the programs used for taxonomic classification. Therefore, this project aims to develop and optimize a pipeline for viral metagenomic analysis originating from NGS sequencing data obtained from several study groups (plasma samples obtained from patients with prostate cancer, undefined febrile illness, and waste pickers). At the same time, parallel comparisons with other bioinformatics programs and mainly viral taxonomy classifiers will be carried out. Adjustments will be performed to the classifiers' databases once they represent high variability of the available viral taxonomic data. Once this is performed, the identified viruses with clinical importance will be assembled and they will be subjected to phylogenetic analysis in order to investigate their molecular epidemiology. This proposal will allow a deeper insight into the metavirome of different groups of patients.(AU)
