Abstract
En 中文
• Marked inter- and intraspecific variation in Micrurus venoms from Bahia. • Three venom phenotypes identified based on geography and taxonomy. • Proteomic profiles reveal PLA2-and 3FTx-dominant venom compositions. • Antivenom neutralized PLA2-rich venoms but failed against 3FTx-rich ones. • Findings highlight evolutionary plasticity and therapeutic implications.
