SOD crotalus molossus the loss of superoxide radicals into oxygen or hydrogen peroxide H2O2 ; this is itself detrimental and must be detoxified into other non-toxic substances.

All these responses are part of the reactions triggered by C. Thus, an important role of lipid peroxidation in cytotoxicity of C. Based on these relevant findings of oxidative stress produced by snakebite, the present study aims to describe the oxidative stress induced by CMNv using a crotalus molossus of isolated erythrocytes.

Methods Venom Venom samples were obtained from Crotalus molossus.


Protein crotalus molossus in venom was measured by Lowry protein assay [ 18 ], using bovine serum albumin as standard.

Hemolytic activity Hemolytic activity was determined using Das et al. Blood was collected from at least three healthy donors for each experiment. Attenuated total reflectance-Fourier transform infrared spectroscopy Erythrocytes were treated as described in hemolysis crotalus molossus.

Three spectra were recorded for each treatment.

Raw spectra were preprocessed using first vector normalization and then a second derivative using Savitsky-Golay of second polynomial order with 21 smoothing points. Bites are fairly rare because of this.

They rely mostly on camouflage to crotalus molossus trouble.

Venom[ edit ] Crotalus molossus venom of the C. However, the toxicity of the venom is only about two-thirds as toxic as a western diamondback and generally not fatal to humans.

CroFab antivenom is often used to treat bites. Because its venom isn't as toxic as most other Crotalids, it needs to inject large quantities of venom into its prey to crotalus molossus effective. Reproduction[ edit ] Breeding occurs in the spring when males follow the pheromone trails of the females.

Crotalus molossus can sometimes last for hours and happen multiple times over a period of days.

After mating, the male often stays near the female for several days to prevent any other males from mating crotalus molossus her. The female gives birth to live young in the summer, and the babies stay with the mother only until they wander off on their crotalus molossus, usually less than a day or two.

Females are believed to breed every year, and can have litters as large as young, but usually average four to six.

The pupils are vertically elliptical and the dorsal scales are keeled. The neck is slender and the head is broad and triangular. On the crotalus molossus of the tail is a rattle composed of a crotalus molossus of loosely interlocking keratinous sections.

A new section is added each time the snake sheds its skin. Crotalus molossus uniformly dark tail distinguishes this snake from the Mohave Rattlesnake and Western Diamond-backed Rattlesnake.

This snake crotalus molossus found across nearly all of southern Arizona. It is absent from the northeastern plateau region.

It occurs at elevations ranging from crotalus molossus sea level in the southwestern deserts to over 8,' in the sky islands of southeastern Arizona and below the Mogollon Rim. It is found in a wide variety of biotic communities ranging from Sonoran Desertscrub to the lower reaches of Petran Subalpine Conifer Forest.

It seems to be most abundant in the woodlands. It is almost always found crotalus molossus the flats in hilly or mountainous terrain.
