Inhibition of metalloproteinases in Bothrops asper venom by endogenous peptides
Toxicon, 1993Bothrops asper venom contains a variety of degradative enzymes, including metal-ion dependent proteinases as well as low molecular weight peptides. Two of these peptides, pyroglutamate-glutamine-tryptophan (pEQW) and pyroglutamate-asparagine-tryptophan are present in crude venom at concentrations of about 4.5 and 1 mM, respectively.

Epidemiological, clinical and therapeutic aspects of Bothrops asper bites
Toxicon, 2009Bothrops asper inflicts the majority of snakebites in Central America and in the northern regions of South America, mostly affecting young agricultural workers in rural settings. This species is capable of provoking severe envenomings associated with local and systemic manifestations.

Studies on the venom proteome of Bothrops asper: Perspectives and applications
Toxicon, 2009Bothrops asper is responsible for the vast majority of snakebite accidents in Central America and several studies have demonstrated that specific toxic and enzymatic activities of its venom vary with the geographic origin and age of the specimens. Variability in venom proteins and enzymes between specimens from the Caribbean and the Pacific versants of

Characterization of a metallo-proteinase from Bothrops Asper (terciopelo) snake venom
Toxicon, 1987Metalloproteinase from the venom of Bothrops asper (proteinase G) is a glycoprotein with 1% neutral hexose and 3.5 moles of sialic acid per mole of protein. It hydrolyses a number of protein substrates such as casein, hemoglobin, gelatin and fibrinogen, whose alpha chain is degraded preferentially.

Skeletal muscle regeneration after myonecrosis induced by Bothrops asper (terciopelo) venom
Toxicon, 1986In order to assess the extent of regeneration, creatine kinase content of injected gastrocnemius muscle were determined at four time intervals after inoculation. Simultaneously, the diameters of regenerating fibers were measured, the wet weight of the gastrocnemius was recorded and electrophoretic patterns of muscle proteins and histology of the tissue

Natural history of the terciopelo Bothrops asper (Serpentes: Viperidae) in Costa Rica
Toxicon, 2009The terciopelo Bothrops asper is the only lancehead species widely distributed in the humid lowlands of Middle America and northwestern South America. Its large body size, relative abundance and cryptic habits contribute to the high incidence of snakebites induced by this species throughout its distribution.

Bothrops asper (Viperidae) Snakebite and Field Researchers in Middle America
Biotropica, 1994The problem of pitviper bite in field researchers working in Middle America (Mexico to Panama) was studied using case histories of nine biologists and one project employee bitten during the period of 1980 to 1991. All snakes involved were Bothrops asper. Based on local tissue and systemic effects, seven cases were severe, there ith permanent disability.
