Monkeying around with venom: an increased resistance to α-neurotoxins supports an evolutionary arms race between Afro-Asian primates and sympatric cobras

open access: yesBMC Biology, 2021
Background Snakes and primates have a multi-layered coevolutionary history as predators, prey, and competitors with each other. Previous work has explored the Snake Detection Theory (SDT), which focuses on the role of snakes as predators of primates and ...

Challenges in diagnosing and treating snakebites in a rural population of Tamil Nadu, India: the views of clinicians [PDF]

open access: yes, 2017
Snakebites cause death, disability and economic devastation to their victims, people who live almost exclusively in rural areas. Annually an estimated two million venomous bites cause as many as 100,000 deaths worldwide as well as hundreds of thousands ...

One Bite, Two Severe Envenomations Despite Antivenom Therapy: A Case Report

open access: yesClinical Case Reports, Volume 13, Issue 7, July 2025.
ABSTRACT This case report describes a 12‐year‐old child who was bitten by a cobra and developed two distinct systemic neurotoxic episodes, 19 h apart, along with severe local envenoming, despite receiving appropriate treatment with antivenom and making a full recovery.

The management of a blood donor bitten by a snake [PDF]

open access: yes, 2017
The worldwide burden of snakebite is high and venomous snakes are found in many regions of the world and are a threat to public health. In Italy, for instance, viper bites are an infrequent but not negligible event.

An N‐Terminally Elongated Peptide From Conus rolani Defines a New Class of Ribbon α‐Conotoxins Targeting Muscle nAChRs

open access: yesThe FASEB Journal, Volume 39, Issue 12, 30 June 2025.
α‐RoIA is an atypical N‐terminally elongated conotoxin discovered in Conus rolani. N‐terminal elongation delays activity in vivo; however, this elongation must be removed to block muscle nicotinic acetylcholine receptors (nAChRs). Only the truncated ribbon isoform of RoIA blocks muscle nAChRs.

Protease Activity Profiling of Snake Venoms Using High-Throughput Peptide Screening

open access: yesToxins, 2019
Snake venom metalloproteinases (SVMPs) and snake venom serine proteinases (SVSPs) are among the most abundant enzymes in many snake venoms, particularly among viperids. These proteinases are responsible for some of the clinical manifestations classically

An Appetite for Destruction: Detecting Prey-Selective Binding of α-Neurotoxins in the Venom of Afro-Asian Elapids

open access: yesToxins, 2020
Prey-selective venoms and toxins have been documented across only a few species of snakes. The lack of research in this area has been due to the absence of suitably flexible testing platforms.
