Comp Biochem Physiol B. 1993 Nov;106(3):595-600. doi: 10.1016/0305-0491(93)90136-s.

Abstract

1. The venoms of two Mojave rattlesnakes and those of their offsprings were analyzed for Mojave toxin and hemorrhagic toxin. 2. The venom of one female, collected in Pima County, Arizona, and the venoms of her six offspring contained hemorrhagic toxin but not Mojave toxin (venom B). 3. The venom of the second female, captured in El Paso County, Texas, contained both toxins (A+B venom). Of her 10 offspring, five contained venom with both toxins, two had hemorrhagic toxin only, and three contained neither toxin. 4. Venoms that caused hemorrhage also inactivated complement. A pool of the venoms of the venom B offspring was less toxic than adult pooled venom A.
