Inflammatory Reaction Induced by Two Metalloproteinases Isolated from Bothrops atrox Venom and by Fragments Generated from the Hydrolysis of Basement Membrane Components

Toxins, 2020
Snake venom metalloproteinases (SVMPs) play an important role in local tissue damage of snakebite patients, mostly by hydrolysis of basement membrane (BM) components.

Bleeding Disorders in Bothrops atrox Envenomations in the Brazilian Amazon: Participation of Hemostatic Factors and the Impact of Tissue Factor

Toxins, 2020
Bleeding is a common hemostatic disorder that occurs in Bothrops envenomations. We evaluated the changes in coagulation, fibrinolysis components, and platelets in Bothrops atrox envenomations with bleeding. This is an observational study with B.

Infundibular sperm storage and uterine muscular twisting in the Amazonian lancehead, Bothrops atrox

The Anatomical Record, 2020
Although knowledge about the reproduction of snakes of the genus Bothrops has increased recently, many questions remain regarding sperm storage by these neotropical pitvipers. The relationship between two known sperm storage sites—the nonglandular uterus

The absence of thrombin-like activity in Bothrops erythromelas venom is due to the deletion of the snake venom thrombin-like enzyme gene.

PLoS ONE, 2021
Snake venom thrombin-like enzymes (SVTLEs) are serine proteinases that clot fibrinogen. SVTLEs are distributed mainly in venoms from snakes of the Viperidae family, comprising venomous pit viper snakes.

Predation on Amerotyphlops brongersmianus (Squamata, Typhlopidae) by Bothrops moojeni (Squamata, Viperidae) in west Brazil

Caldasia, 2019
Ophyophagy is a common feeding habit in snakes; however, there are few records of this behavior for the genus Bothrops. Here, we report the first case of predation of Bothrops moojeni upon Amerotyphlops brongersmianus.

Review of the diet for Cerdocyon thous (Carnivora: Canidae), and the first record of Bothrops moojeni (Serpentes: Viperidae) as prey

Caldasia, 2022
The crab-eating fox Cerdocyon thous has a diverse diet ranging from plants to vertebrates, but its diet has never been comprehensively reviewed. Here, we provide the first such review and report the first-ever record of C.

Coagulotoxicity of Bothrops (Lancehead Pit-Vipers) Venoms from Brazil: Differential Biochemistry and Antivenom Efficacy Resulting from Prey-Driven Venom Variation

Toxins, 2018
Lancehead pit-vipers (Bothrops genus) are an extremely diverse and medically important group responsible for the greatest number of snakebite envenomations and deaths in South America.
