Comparative analysis of venom composition, enzymatic activity, and antivenom immunorecognition in neonates of four Bothrops species

Abstract

This study compared venom composition, enzymatic activities, and antivenom immunorecognition in neonates from three Bothrops clades. Results suggest potential clade-specific markers in electrophoretic profiles and phospholipase-A2 and L-amino acid oxidase enzymatic activities. These findings suggest that neonate venom traits may serve as auxiliary parameters for taxonomic differentiation, though further research is needed to account for individual and sexual variability.
