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.

Horse immunization with short-chain consensus α-neurotoxin generates antibodies against broad spectrum of elapid venomous species

Nature Communications, 2019
Antivenoms, obtained by venom immunization, have narrow species coverage due to low immunogenicity of venom neurotoxins. Here the authors immunize horses with a designed recombinant consensus neurotoxin, and the resulting antisera protect mice from ...

Coral snake venoms: mode of action and pathophysiology of experimental envenomation

Revista do Instituto de Medicina Tropical de São Paulo, 1987
Coral snakes, the New World Elapidae, are included in the genera Micniroides and Micrurus. The genus Mlcrurus comprises nearly all coral snake species and those which are responsible for human snake-bite accidents.

Snakes on Trains: Railways May Sway Goa's King Cobra Distribution

Biotropica, Volume 58, Issue 1, January 2026.
Distribution of King Cobras (Ophiophagus kaalinga) across Goa, India, shows occurrence in climatically suitable forests and, notably, also along low‐suitability railway corridors, suggesting that snakes may be accidentally transported on trains, leading to range expansion.

Elapid venom toxins: multiple recruitments of ancient scaffolds [PDF]

European Journal of Biochemistry, 1999
Nigroxins A and B, two myotoxic phospholipases A2 (PLA2s) from the venom of the American elapid Micrurus nigrocinctus, belong to a new PLA2 subclass. Their primary structures were established and compared with those of PLA2s that have already been studied with respect to myotoxic activity.

Clinicopathological Features, Management, and Outcomes of Zebra Spitting Cobra (Naja nigricincta nigricincta) and Puff Adder (Bitis arietans) Snakebites in Namibia

BioMed Research International, Volume 2026, Issue 1, 2026.
Snakebite envenomation remains an important public health concern in Namibia, particularly following bites from the zebra spitting cobra (Naja nigricincta nigricincta) and the puff adder (Bitis arietans). However, the clinical presentations and management outcomes of these snakebites remain poorly characterized.

Development of an Immunofluorescence Lateral Flow Assay for Detecting Four Medically Important Snake Venoms in China

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Snakebite envenomation requires rapid venom identification for effective treatment, a need unmet by current diagnostics in China. This study aimed to develop a rapid, multiplex immunofluorescence lateral flow assay for the simultaneous detection of four major venomous snakes: Deinagkistrodon acutus, Bungarus multicinctus, Naja atra, and Agkistrodon ...

Quaternary Habitat Fluctuations and Demographic Dynamics in Turtles Inferred From Environmental Niche Modelling and Whole Genome Data

Molecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT Quaternary climatic fluctuations had a substantial influence on ecosystems, species distribution, phenology and genetic diversity, driving extinction, adaptation and demographic shifts during glacial periods and postglacial expansions. Integration of genomic data and environmental niche modelling can provide valuable insights on how organisms ...

Generalization of predator recognition: Velvet geckos display anti-predator behaviours in response to chemicals from non-dangerous elapid snakes

Current Zoology, 2010
Many prey species detect chemical cues from predators and modify their behaviours in ways that reduce their risk of predation. Theory predicts that prey should modify their anti-predator responses according to the degree of threat posed by the predator ...

A novel in vitro potency assay of antisera against Thai Naja kaouthia based on nicotinic acetylcholine receptor binding

Scientific Reports, 2017
Snake envenomation is an important medical problem. One of the hurdles in antivenom development is the in vivo assay of antivenom potency which is expensive, gives variable results and kills many animals.
