A cornerstone of classical virulence evolution theories is the assumption that pathogen growth rate is positively correlated with virulence, the amount of damage pathogens inflict on their hosts. Such theories are key for incorporating evolutionary principles into sustainable disease management strategies. Yet, empirical evidence raises doubts over this central assumption underpinning classical theories, thus undermining their generality and predictive power. In this paper, we identify a key component missing from current theories which redefines the growth-virulence relationship in a way that is consistent with data. By modifying the activity of a single metabolic gene, we engineered strains of Magnaporthe oryzae with different nutrient acquisition and growth rates. We conducted in planta infection studies and uncovered an unexpected non-monotonic relationship between growth rate and virulence that is jointly shaped by how growth rate and metabolic efficiency interact. This novel mechanistic framework paves the way for a much-needed new suite of virulence evolution theories.

Background: Refractory epilepsy poses significant challenges in clinical management due to its resistance to standard antiepileptic therapies, necessitating the exploration of more effective treatment regimens. Lamotrigine, with its proven efficacy and tolerability, offers potential benefits when combined with traditional medications like valproate, though its comprehensive impact on clinical outcomes and neurological markers requires further study.
Objective: To analyze the improvement effect of combined application of lamotrigine on refractory epilepsy patients and its impact on patients' EEG and neurological function.
