Lymphosarcoma with Lymphoid Leukemia in an Aruba Island Rattlesnake, Crotalus unicolor

Geographic Diet Variation of Mojave Rattlesnake (Crotalus scutulatus)

Rain-harvesting by the Southwestern Speckled Rattlesnake (crotalus Mitchellii Pyrrhus)

Acquiring water is a challenge for desert animals, and organisms inhabiting arid regions have evolved morphological, physiological, and behavioral traits to maintain an appropriate water balance. On four occasions, I observed rain-harvesting or observed behaviors suggestive of rain harvesting in a population of speckled rattlesnakes (Crotalus mitchellii) in the Mojave Desert of southwestern Nor...

Fibrinogenolytic afibrinogenemia after envenomation by western diamondback rattlesnake (Crotalus atrox).

The absence of fibrinogen and the presence of plasmic fragments X, Y, D, and E were demonstrated in a patient bitten by a western diamondback rattlesnake, Crotalus atrox. The factor VIII level and the platelet count were within normal limits. There were distinct changes of protease inhibitors in the patient's plasma. Alpha-1-protease inhibitor was elevated. Antithrombin-III was only slightly de...

Cardiovascular actions of rattlesnake bradykinin ([Val1,Thr6]bradykinin) in the anesthetized South American rattlesnake Crotalus durissus terrificus.

Incubation of heat-denatured plasma from the rattlesnake Crotalus atrox with trypsin generated a bradykinin (BK) that contained two amino acid substitutions (Arg1 --> Val and Ser6 --> Thr) compared with mammalian BK. Bolus intra-arterial injections of synthetic rattlesnake BK (0.01-10 nmol/kg) into the anesthetized rattlesnake, Crotalus durissus terrificus, produced a pronounced and concentrati...
