Venoms of Calliophis bivirgata and Calliophis intestinalis were studied.
Methods included indirect ELISA and lethality neutralization in mice.
Both venoms showed negligible cross-immunoreactivity against elapid antivenoms.
C. bivirgata venom lethality in mice was not cross-neutralized by the antivenoms.
There is implication on the production of a pan-regional poly-specific antivenom.
