Development of a sensitive enzyme immunoassay (ELISA) for specific identification of Lachesis acrochorda venom

Journal of Venomous Animals and Toxins including Tropical Diseases, 2012
The snake genus Lachesis provokes 2 to 3% of snakebites in Colombia every year. Two Lachesis species, L. acrochorda and L. muta, share habitats with snakes from another genus, namely Bothrops asper and B. atrox.

Polymeric Nanoparticles for the Diagnosis and Treatment of Snakebite

Macromolecular Chemistry and Physics, Volume 227, Issue 1, 15 January 2026.
Snakebite envenomation affects between 1.8 and 5.5 million people annually, many of whom suffer disabilities or even death. Current antivenoms are composed of plasma‐derived antibodies. However, there remains an underexplored opportunity to utilise polymer‐based nanoparticles.

Ontogenetic variability of Bothrops atrox and Bothrops asper snake venoms from Colombia

Toxicon, 2003
The lancehead snakes Bothrops asper and Bothrops atrox inflict 70-90% of the 3000 bites reported every year in Colombia. In this work, the venoms of B. atrox from Meta (Villavicencio, 33 specimens) and B. asper from Antioquia (San Carlos, 45 specimens), all of them born in captivity, were obtained at different ages (0-6 months; 1, 2 and 3-years old ...

Morphological traits and environmental preferences of the Blunt‐headed tree snake Imantodes cenchoa: the effects of sex and ontogeny

Journal of Zoology, Volume 328, Issue 1, Page 41-51, January 2026.
Understanding how animals interact with their environment across life stages is key for conservation. In our long‐term study of the Blunt‐headed tree snake (Imantodes cenchoa) in the tropical rainforest of Los Tuxtlas, Mexico, we tracked over 240 individuals and found age‐related differences in environmental preferences.

Heparin-antivenom association: differential neutralization effectiveness in Bothrops atrox and Bothrops erythromelas envenoming [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2001
Heparin, in some regions of Brazil has been used in the treatment of bothropic accidents, but the data found in the literature are inconclusive about its effectiveness. The venoms of Bothrops atrox and of B. erythromelas were characterized according to their biological activities. The capacity of heparin in neutralizing these activities was tested with

Animal Venom Pharmacological Resources: Exploiting Bioactive Peptides to Target Multi–Drug‐Resistant Bacteria

Biochemistry Research International, Volume 2026, Issue 1, 2026.
Background The escalating rise of multi–drug‐resistant (MDR) bacterial strains significantly threatens global health, creating a “silent pandemic” prompted by natural selection, gene mutation, and horizontal gene transfer. This crisis is worsened by the deficit in the development of new treatments, necessitating the innovative discovery of new potent ...
