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.

Microvesicles in the venom of Crotalus durissus terrificus (Serpentes, Viperidae)

Toxicon, 2007
Microvesicles with electron-dense content are consistently observed by transmission electron microscopy on the luminal face of secretory cells of venom glands of viperid snakes. In this work, we evaluated their presence in Crotalus durissus terrificus venom glands and also in freshly collected venom.

Effects of Crotalus durissus cascavella venom in the isolated rat kidney

Toxicon, 1998
Crotalus durissus cascavella (C.d.c) is a snake usually found in scrubland of Brazilian Northeast and its bite constitutes an important public health problem. Isolated kidneys from wistar rats, weighing 240 to 280 g, were perfused with Krebs Henseleit solution containing 6 g% of previously dialysed bovine serum albumin.

WITHDRAWN: Microvesicles in the venom of Crotalus durissus terrificus (Serpentes, Viperidae)

Toxicon, 2006
The Publisher regrets that this article was an accidental duplication of an article that has already been published in Toxicon, 49 (2007) 106-110, . The duplicate article has therefore been withdrawn.

Identification of crotasin, a crotamine-related gene of Crotalus durissus terrificus

Toxicon, 2004
Crotamine is a cationic peptide (4.9 kDa, pI 9.5) of South American rattlesnake, Crotalus durissus terrificus' venom. Its presence varies according to the subspecies or the geographical locality of a given species. At the genomic level, we observed the presence of 1.8 kb gene, Crt-p1, in crotamine-positive specimens and its absence in crotamine ...

Enzymatic activities and other characteristics of Crotalus durissus cumanensis venom

Toxicon, 1974
Abstract Chemical, physical and biochemical properties of Crotalus durissus cumanensis venom were investigated. Most of the chemical and physical characteristics conform with the general pattern for Crotalidae, but there are noticeable variations in relation to the degree of activities of the ten types of enzymes assayed.
