Evolutionary dynamics of the successful expansion of pandemic Vibrio parahaemolyticus ST3 in Latin America
Campbell, A.M. et al. – Nature Communications 15, 7828
The evolutionary mechanisms behind global pathogen strain expansions are not well understood, but the spread of the Vibrio parahaemolyticus clone (VpST3) in Latin America offers key insights. This study found that the VpST3 strain was introduced in Latin America earlier than previously thought, adapting successfully to local marine climates through genetic changes that improved resilience and environmental fitness. These findings reveal how this marine pathogen can expand globally by evolving to thrive in distinct climate conditions.
