Unraveling the complicated genetics behind the tiger rattlesnake's venom could help researchers identify new medications to treat human conditions. University of South Florida.
Like science, tech, and DIY projects? In addition to the destructive actions of the venom components themselves, some proteins trick our own immune system to fight against our own cells. Specifically, the actions of metalloproteases and phospholipases trigger an immune response at the site of the wound. Immune cells such as leukocytes signal an increased immune response by releasing messengers such as interleukin Since the venom components are not a cohesive force, and with no bacteria to attack, the immune system instead launches an attack that adds to the destruction of our own tissues.
The damage done by our own immune system is doubly troubling considering that antivenom does not help to mitigate its effects. Studies have found that, when the immune system is shut down, necrotic effects of snake venom are greatly reduced.
The use of Benadryl, for instance, can lessen the swelling and edema associated with envenomation. A Note on Conservation. Although snakes are often feared and persecuted throughout much of their ranges in the United States and elsewhere, they nonetheless occupy a valuable place in the ecology of many ecosystems. There are hundreds of species of snakes in the U. Venomous snakes can be safely and effectively avoided by using common sense. If a snake is thought to be venomous, or if it is not known whether it is venomous, the safe thing to do is to leave it alone.
Remember that most bite victims are bitten because they are attempting to handle or kill the snake. Snakes perform valuable services such as controlling rodents and other pests. A recent study has shown that timber rattlesnakes may reduce the incidence of Lyme disease in the northeastern U. An estimated 2, to 4, ticks were removed from the northeastern U. Recent research suggests that rattlesnakes may help disperse the seeds of grasses and other plants.
Rodents eat grass seeds and those of other plants, but the seeds do not normally survive through the digestive process of rodents. Rattlesnakes and many other species of snakes are experiencing declines in populations in the United States due to loss of habitat, continued persecution, and emerging diseases such as the snake fungus Ophidiomyces ophiodiicola. The eastern diamondback rattlesnake Crotalus adamanteus Figure 2 has declined to the point where the species has been petitioned for protection as a threatened species under the Endangered Species Act.
