Dermal contact with certain caterpillar species in Argentina can cause systemic and local poisoning, with several envenomation cases reported, particularly in Misiones province.
The study compared the protein composition and enzymatic properties of bristle extracts from three caterpillar species known to cause accidents, specifically from the families Megalopygidae and Saturniidae.
Findings revealed similarities in venom profiles and activities, with specific proteins linked to coagulation disturbances, highlighting important insights into their toxic effects on humans and potential future research avenues.
