Abstract

The exposure of the human gut to antibiotics can have a great impact on human health. Antibiotics pertain to the preservation of human health and are useful tools for fighting bacterial infections. They can be used for curing infections and can play a critical role in immunocompromised or chronic patients, or in fighting childhood severe malnutrition. Yet, the genomic and phylogenetic diversity of the human gut changes under antibiotic exposure. Antibiotics can also have severe side effects on human gut health, due to the spreading of potential antibiotic resistance genetic traits and to their correlation with virulence of some bacterial pathogens. They can shape, and even disrupt, the composition and functioning diversity of the human gut microbiome. Traditionally bacterial antibiotic resistances have been evaluated at clone or population level. However, the understanding of these two apparently disparate perspectives as both friends and foes may come from the study of microbiomes as a whole and from the evaluation of both positive and negative effects of antibiotics on microbial community dynamics and diversity. In this review we present some metagenomic tools and databases that enable the studying of antibiotic resistance in human gut metagenomes, promoting the development of personalized medicine strategies, new antimicrobial therapy protocols and patient follow-up.
