The most enigmatic group of rattlesnakes is the long-tailed rattlesnake group, consisting of three species: Crotalus ericsmithi, Crotalus lannomi and Crotalus stejnegeri. These species have been the least studied rattlesnakes in all aspects, and no study on the characterization of their venoms has been carried out to date. Our main objective was to investigate the proteomic composition, as well as some of the biochemical and toxic activities of these venoms, and their neutralization by commercial antivenom.

- Intraspecific variation in snake venoms is notable, yet there are limited studies in Mexico, particularly involving the medically significant Crotalus basiliscus rattlesnake.
- Research reveals that juvenile rattlesnake venoms are more lethal and contain higher levels of certain toxins compared to adult venoms, which show a distinct biochemical profile.
- The study highlights the efficacy of different lots of Birmex antivenom, noting their ability to neutralize some venom but not crotamine, suggesting the need for better incorporation of this toxin in antivenom production for improved effectiveness.
