Co-adapting but not static predators facilitate prey adaptation to a fluctuating environment

Lou Guyot, Aryan Ramachandran, Luis‐Miguel Chevin

This study shows that prey adaptation to a fluctuating environment depends on whether predators co-adapt or remain static, challenging predator removal as a conservation strategy.

Antibiotic tolerance due to filamentation shapes β-lactam pharmacodynamics in Escherichia coli

Aryan Ramachandran, Josia Pool, J. Arjan G. M. de Visser, Hilje M. Doekes, Aditi Batra

This study shows that cefotaxime has a two-step pharmacodynamic curve against E. coli due to filamentation and differential binding to penicillin-binding proteins, offering a mechanistic model for antibiotic action.

PATHOGEN GROWTH AND VIRULENCE DYNAMICS DRIVE THE HOST EVOLUTION AGAINST COINFECTIONS

Srijan Seal, Dipendra Nath Basu, Kripanjali Ghosh, Aryan Ramachandran, Rintu Kutum, Triveni Shelke, Ishaan Gupta, Imroze Khan

This study shows that host evolution against coinfections is influenced by the growth and virulence dynamics of individual pathogens, with fast-acting pathogens hindering adaptive success.
