A comparative study of biological activities of crotoxin and CB fraction of venoms from Crotalus durissus terrificus, Crotalus durissus cascavella and Crotalus durissus collilineatus

Toxicon, 2004
In Brazil, the Crotalus durissus terrificus subspecie is the most studied, particularly concerning its crotoxin. Crotoxin is the major toxic component of the South American rattlesnake Crotalus durissus venom. It is composed of two different subunits, CA called crotapotin and CB weakly toxic phospholipase A2 with high enzymatic activity. In this paper,

Antifungal activity of Crotalus durissus cumanensis venom

Mycoses, 2002
Summary. The susceptibility to Crotalus venom of 14 yeast and 10 mould fungal isolates was assessed. This venom was tested in a standardized well diffusion test, using 400 µg/20 µl well. The percentage of susceptibility to yeast isolates was 78.6% (> 8 mm); that for filamentous isolates was 50% (> 8 mm).

The heart of the South American rattlesnake, Crotalus durissus

Journal of Morphology, 2010
AbstractMost anatomical and physiological studies of the sauropsid heart have focused on species with extraordinary physiologies, and detailed anatomical descriptions of hearts from sauropsids with more common physiologies are therefore warranted. Here, we present a comprehensive study of the cardiac anatomy of the South American rattlesnake (Crotalus ...

Feeding Mechanism in the Rattlesnake Crotalus durissus

Amphibia-Reptilia, 1986
Abstract Cineradiography and electromyography were used to study the strike and swallowing behaviour of the rattlesnake, Crotalus durissus. From the data gathered, we describe the kinetic events of the cranial bones correlated with both the activity of individual jaw muscles (electromyograms) and with the calculated relative forces produced ...

Seasonality in Crotalus durissus venom

Toxicon
Rattlesnakes belonging to the genus Crotalus are widely distributed throughout the Americas. In Brazil, symptoms commonly associated with envenomation by Crotalus durissus collilineatus include myalgia, rhabdomyolysis, renal failure, neurotoxicity, and progressive paralysis, which are related to the protein composition of this venom.

Crotalus durissus terrificus Laurenti

1971
The karyotypes shown came from short term blood cultures. The female is heterogametic; the fourth pair of macrochromosomes consists of the sex chromosomes ZZ in the male, and ZW in the female. The karyotypes are from a male specimen of Minas Gerais and from a female of Sao Paulo, Brazil, both preserved in the Collection of the Instituto Butantan.
