What drives the evolution of antibiotic resistance? How does resistance spread in bacterial populations? Can we predict the evolution of antibiotic resistance? We are tackling these and other questions in the Evolutionary Dynamics of Antibiotic Resistance Lab, located at the Ramón y Cajal Institute for Health Research (Ramón y Cajal University Hospital) in Madrid.
Antibiotic resistant bacterial infections are arguably one of the major threats to human health. Our laboratory seeks to understand the ecological and evolutionary processes that drive the emergence and spread of antibiotic resistant clones. Ultimately, this will allow us to develop new therapeutic approaches to tackle the evolution of antimicrobial resistance. We work on the following three highly inter-related topics (among others).
Resistance to virtually all antibiotics has been reported soon after their introduction to clinical use, suggesting that the apparition of resistance will eventually outpace humankind’s ability to develop new antimicrobial compounds. Therefore, there is an urgent need to develop new intervention strategies to counteract the evolution of antibiotic resistance. In the lab, we take advantage of recent molecular biology advances to develop new approaches to overcome antibiotic resistance in bacterial populations.
One of the main drivers of the antimicrobial resistance crisis is the emergence and global dissemination of epidemiologically successful drug-resistant clones. These high-risk clones have acquired certain adaptive traits that increase their pathogenicity and survival skills, including the acquisition of antibiotic resistance. We take advantage of cutting-edge genetic technologies to understand the ecological and evolutionary bases of high-risk clone epidemiological success. We believe that this mechanistic understanding will feed essential information for predicting (and avoiding) future expansions of antimicrobial resistant high-risk clones and provide a conceptual framework to better manage infections.
Mobile genetic elements play a crucial role in bacterial ecology and evolution because they mobilize key traits by horizontal gene transfer. However, the evolutionary impact of mobile genetic elements goes above and beyond being mere gene delivery platforms. Recent evidence suggests that mobile genetic elements evolve differently than chromosomes. Using experimental approaches combined with mathematical simulations and bioinformatic analyses, we try to decipher and understand the rules governing mobile genetic element evolution.

La convocatoria de la JdC estaba abierta a candidatos de fuera de la UE. Una candidata,verdaderamente excepcional por cierto, la pide. Se la conceden. La resolución definitiva sale en Noviembre, dándole apenas 1 mes para incorporarse. Los papeles de extranjería tardan + de 1 mes.
Now out: plasmids frequently highjack components of plasmids that highjack other plasmids to conjugate between bacteria. And these elements have the highest densities of antibiotic resistance genes. Kudos to @M_AresArroyo (& @ccoluzzi1 ) https://academic.oup.com/nar/advance-article/doi/10.1093/nar/gkac1079/6849495?searchresult=1 see 🧵⬇️ https://twitter.com/epcrocha/status/1544256485278064640
A decade ago, w/@FdlC61 @cssmillie & Mapi we showed that >50% of plasmids lack protein coding genes for conjugation. Yet, they move. How? We now suggest that most plasmids in E coli and S aureus engage in conjugation. Great work led by @M_AresArroyo https://www.biorxiv.org/content/10.1101/2022.07.04.498229v1
