Genomic dynamics of microbiomes, local adaptation and epidemiology

We are carrying out studies that allow us to have an understanding of how pathogenic microorganisms flow between terrestrial, aquatic and anthropogenic environments, and to this end, we carry out the functional analysis of the metagenome and metapangenome. 

We also study the evolutionary dynamics of antibiotic resistance and bacterial virulence in both bacterial genomes and microbiomes belonging to different environments (e.g. human and animal gut, and natural environments). We aim to understand how these genetic traits are spread between different microbiomes, linking animal, human and environmental health, in line with the OneHealth concept. 

So far, our studies have allowed us to model the effect of human contact on the transmission of antibiotic resistance genes, as well as to compare the correlation between the abundance and diversity of resistance genes and those of bacterial virulence, in human, animal and environmental microbiomes with different types of antibiotic exposure and anthropogenic contact.

Role of bacterial mobile genetic elements on genome evolution

We aim to understanding how genome plasticity, mediated by mobile genetic elements such as plasmids, transposons, integrons, phages, ICEs, etc., contributes to microbial communities that respond to stress conditions, such as antibiotic exposure or anthropogenic contact, and adapt to the environment.

We have studied the correlation between the diversity and abundance of different types of bacterial mobile genetic elements, and antibiotic resistance genes, both in microbiomes and in a collection of over 16,000 bacterial reference genomes. Our results suggest that genes encoding for antibiotic resistance that are most commonly used in human medicine, veterinary medicine and agriculture are those with the greatest potential to be epidemic-prone.

We want to better understand the spread of plasmids in bacterial communities.

Pathogenic bacterial genomics and food safety

We study the genomes of human foodborne pathogenic bacteria, such as Listeria monocytogenes, Campylobacter sp., Salmonella sp., and others. We are interested in understanding their distribution in environmental microbiomes, such as aquaculture production environments, linked to the food chain. In this context, we aim to understand which genetic traits are involved in their adaptation to the food production environment-

We also seek genomic evidence for the persistence of the Listeria monocytogenes phenotype in food processing environments.

Science education and outreach

We actively contribute to the development of educational games and other activities to disseminate scientific knowledge about biological evolution and, particularly, the evolution of microbial genomes and their zoonotic transmission.
