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

Clinical 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.

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

Toxins, 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.

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

The 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.

Early cardiovascular collapse after envenoming by snakes in Australia, 2005–2020: an observational study (ASP‐31)

Medical Journal of Australia, Volume 222, Issue 6, Page 313-317, April 2025.
Abstract Objectives To investigate the frequency, timing, and characteristics of cardiovascular collapse after snakebite in Australia, and the complications of collapse following envenoming. Study design Observational study; analysis of prospectively collected demographic and clinical data.

Brightfield microscopy images of RPTEC/TERT1 cells in response to three different venoms, which were used to quantify the cell surface area.

, 2023
Conditions shown for three different venoms: cytotoxic viper, cytotoxic elapid and non-cytotoxic elapid. Top row represents the ‘training’ of the software to differentiate cell populations (red dots) from the ‘empty well area’ (green dots) using a simple

Ritualistic Male–Male Combat of the Northern King Cobra (Ophiophagus hannah) in Thailand

Ecology and Evolution, Volume 15, Issue 4, April 2025.
Following the recent taxonomic split of the king cobra complex, it is important to provide new information and context to behaviors and natural history linked to each new species. We therefore provide detailed observations of ritualistic male–male combat of the newly described northern king cobra (Ophiophagus hannah).

Review of osteoderm function and future research directions

Journal of Zoology, Volume 325, Issue 1, Page 1-24, January 2025.
Osteoderms are bone plates in the skin that occur in virtually all major tetrapod clades. Much has been speculated about their function, but many questions remain unanswered. This review provides an overview of the current state of knowledge and future research directions in this field.

Prey specificity of predatory venoms

Biological Reviews, Volume 99, Issue 6, Page 2253-2273, December 2024.
ABSTRACT Venom represents a key adaptation of many venomous predators, allowing them to immobilise prey quickly through chemical rather than physical warfare. Evolutionary arms races between prey and a predator are believed to be the main factor influencing the potency and composition of predatory venoms.

Trends in Reptile Holdings Across UK Zoos: Identification of the Factors Responsible for Declining Numbers of Venomous Snake

Zoo Biology, Volume 43, Issue 6, Page 556-569, November/December 2024.
In this study, we describe the trends in reptile holdings across UK zoos. Our results show that despite an overall increase in reptile numbers, there has been a dramatic decline in the number of venomous snakes being kept at UK zoos, and, as a consequence, venomous snakes are being excluded from many of the conservation benefits that zoos provide ...

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

, 2019
Antivenoms are fundamental in the therapy for snakebites. In elapid venoms, there are toxins, e.g. short-chain α-neurotoxins, which are quite abundant, highly toxic, and consequently play a major role in envenomation processes. The core problem is that
