At the Department of Microbiology and Virology, we also investigate the human microbiota focusing at microbiome using molecular biology approaches, bioinformatics, biostatistics and artificial intelligence. We aim to analyze also the host-microbiome interaction and communication. We analyze the potential of microorganisms to serve as biomarkers of non-communicable and communicable diseases and of the changes in the human organism that are related to them. We use state-of-the-art sequencing and omics approaches.
