Researchers have uncovered a hidden split in the venom of Australia’s deadly Eastern Brown Snake. Southern populations create rock-solid blood clots, while northern snakes produce fragile clots that collapse almost instantly — two very different paths to the same deadly outcome. This discovery raises urgent concerns about whether current antivenoms, made from pooled venoms of […]



Summary

Researchers have discovered a significant regional variation in Eastern Brown Snake venom. Southern snakes produce venom causing robust blood clots, while northern snakes create unstable clots that rapidly break down. Both mechanisms are deadly, but this difference presents a challenge for current antivenoms, which are made from pooled venoms. The team believes this discrepancy could explain anecdotal reports of antivenom ineffectiveness and warrants further investigation to refine antivenom production to account for these regional venom differences, potentially improving treatment outcomes for snakebite victims.
