The true identity of the enigmatic scorpion Centruroides subgranosus (Kraepelin, 1898), with some taxonomic comments on Centruroides vittatus (Say, 1821) and Centruroides suffusus Pocock, 1902 (Scorpiones: Buthidae)

Euscorpius, 2010
Summary The true identity of Centruroides subgranosus (Kraepelin, 1898) is established based on the examination of the type series. A lectotype and paralectotype are designated. A taxonomic discussion on C. vittatus (Say, 1821) and C. suffusus Pocock, 1902 is provided.

Study of the Acute Toxicity of Scorpion Leiurus macroctenus Venom in Rats. [PDF]

ScientificWorldJournal
Background. The expansion of the territory of human habitation leads to inevitable interference in the natural range of distribution of one or another species of animals, some of which may be dangerous for human life. Scorpions—the Arachnida class and order Scorpiones—can be considered as such typical representatives.

Colombian Scorpion Centruroides margaritatus: Purification and Characterization of a Gamma Potassium Toxin with Full-Block Activity on the hERG1 Channel

Toxins, 2021
The Colombian scorpion Centruroides margaritatus produces a venom considered of low toxicity. Nevertheless, there are known cases of envenomation resulting in cardiovascular disorders, probably due to venom components that target ion channels. Among them,

Intraspecific Variation of Centruroides Edwardsii Venom from Two Regions of Colombia [PDF]

Toxins, 2014
We report the first description studies, partial characterization, and intraspecific difference of Centruroides edwardsii, Gervais 1843, venom. C. edwardsii from two Colombian regions (Antioquia and Tolima) were evaluated. Both venoms showed hemolytic activity, possibly dependent of enzymatic active phospholipases, and neither coagulant nor proteolytic

Allergy to stings and bites from rare or locally important arthropods: Worldwide distribution, available diagnostics and treatment

Allergy, Volume 78, Issue 8, Page 2089-2108, August 2023., 2023
Abstract Insect venom allergy is the most frequent cause of anaphylaxis in Europe and possibly worldwide. The majority of systemic allergic reactions after insect stings are caused by Hymenoptera, and among these, vespid genera induce most of the systemic sting reactions (SSR). Honey bees are the second leading cause of SSR.

Convergent evolution of toxin resistance in animals

Biological Reviews, Volume 97, Issue 5, Page 1823-1843, October 2022., 2022
ABSTRACT Convergence is the phenomenon whereby similar phenotypes evolve independently in different lineages. One example is resistance to toxins in animals. Toxins have evolved many times throughout the tree of life. They disrupt molecular and physiological pathways in target species, thereby incapacitating prey or deterring a predator.
