Special Issue Introduction:

During the past two decades, the evolution of DNA sequencing technologies has allowed the gathering of
a vast amount of metagenomic data, laying the foundation to study complex microbial communities, also
known as microbiomes. At the dawn of the metagenomic classification era, DNA sequences were mainly
used to unveil the composition of the bacterial communities inhabiting specific environments through
analysis based on the amplification of microbial marker genes. Recently, the more informative shotgun
metagenomics approach allowed the reconstruction of the functional contribution of the bacteria harbored
in the biological samples without the necessity to compromise data during sample preparation. To date,
the interest of the scientific community is rapidly moving to a complete overview of the microbiomes,
involving multiple bioinformatic pipelines aiming at understanding complex dynamics between members
of the same environmental niche and their host.

This Special Issue aims to gather projects that rely on bioinformatics strategies to investigate bacteria,
archaea, protists, and fungi in the frame of microbiome research, highlighting applications in the field of
the human microbiome as well as more unexplored microbiomes, such as non-human animals.
