Venom, venomics, antivenomics
(2009)
Venoms comprise mixtures of peptides and proteins tailored by Natural Selection to act on vital systems
of the prey or victim. Here we review our proteomic protocols for uncoiling the composition,
immunological profile, ...
Snake Venomics and Antivenomics of Bothrops diporus, a Medically Important Pitviper in Northeastern Argentina
(MDPI, 2015-12)
Snake species within genus Bothrops are responsible for more than 80% of the snakebites occurring in South America. The species that cause most envenomings in Argentina, B. diporus, is widely distributed throughout the ...
Venomic analysis of the poorly studied desert coral snake, Micrurus tschudii tschudii, supports the 3FTx/PLA2 dichotomy across Micrurus venoms
(2016)
The venom proteome of the poorly studied desert coral snake Micrurus tschudii tschudii
was unveiled using a venomic approach, which identified ¥38 proteins belonging to only four snake
venom protein families. The ...
Local tissue damage induced by Bothrops snake venoms - A review
(1989-12)
This review focuses on the local effects induced by Bothrops venoms. These envenomation are characterized by myonecrosis, hemorrhage and edema which develop rapidly after venom inoculation. Myonecrosis is caused (a) directly, ...
Venom-Sweet-Venom: N-Linked Glycosylation in Snake Venom Toxins
(BENTHAM SCIENCE PUBL LTD, 2009)
Protein glycosylation represents one of the most important post-translational events, and is a mean of diversifying a protein without recourse to the genome. The venoms produced by snakes contain an abundance of glycoproteins ...
Strategies in 'snake venomics' aiming at an integrative view of compositional, functional, and immunological characteristics of venoms
(2017-04)
This work offers a general overview on the evolving strategies for the proteomic analysis of snake venoms, and
discusses how these may be combined through diverse experimental approaches with the goal of achieving a
more ...
Bioinsecticide action of the venom of Africanized bees Apis mellifera Linnaeus 1758 (Hymenoptera: Apidae): I - The most susceptible age of Diatraea saccharalis Fabricius 1794 (Lepeletier: Pyralidae) eggs to the venom action
(1996-01-01)
The present paper aimed at testing the action of non-lyophilized venom of Africanized bees Apis mellifera through topical applications on Diatraea saccharalis egg masses. The CL50, DL50 and the most susceptible age of eggs ...
Experimental myonecrosis induced by the venoms of South American Micrurus (coral snakes)
(1992)
Venoms from 11 taxa of Micrurus (coral snakes) from Brazil and Colombia were tested for myotoxic activity in mice. All venoms, except that of M. surinamensis, induced myotoxicity as judged by the increase in plasma creatine ...
Snake venomics of crotalus tigris: the minimalist toxin arsenal of the deadliest neartic rattlesnake venom: evolutionary clues for generating a pan-specific antivenom against crotalid type II venoms
(Journal of Proteome Research 11(2): 1382–1390, 2012-02-03)
We report the proteomic and antivenomic characterization of Crotalus tigris venom. This venom exhibits the highest lethality for mice among rattlesnakes and the simplest toxin proteome reported to date. The venom proteome ...
Relationship of venom ontogeny and diet in Bothrops
(1999-06-01)
We studied ontogenetic changes in venom toxicity of the pitvipers Bothrops jararaca and B. alternatus in order to evaluate the relationship between venom action and diet. Toxicity tests (LD50) were performed for the venoms ...
