From Taxonomic Accuracy to Toxin Naming: A Welcome Dialogue in Toxicon

  From Taxonomic Accuracy to Toxin Naming: A Welcome Dialogue in Toxicon By Luis A. Roque | Arácnido Taxonomy When I submitted my correspondence, “When tarantula venom comes from a misnamed spider: The importance of taxonomic accuracy in theraphosid toxinology,” to Toxicon , I hoped it would encourage a broader conversation. The purpose was to draw attention to a problem that benefits from the experience of people working across taxonomy, venom research, and biological databases. Dr. Volker Herzig’s response, “The need for a unified toxin nomenclature for consistent toxin naming,” is precisely the kind of engagement I hoped to see. His contribution acknowledges the importance of identifying venom-source organisms accurately while bringing another essential question into focus: How do we maintain continuity in toxin names when taxonomy and our understanding of toxin function change? Two connected challenges My original correspondence focused on the biological source of venom. In t...

Comparative medical importance of spider bites in Spain over 1997–2020: a retrospective study based on hospital cases coded using ICD

Abstract

Envenomation by terrestrial toxic animals is considered a serious risk to human health worldwide. Snakes, hymenopterans, spiders, and scorpions have mainly attracted the attention of medical literature. However, the relative importance of spiders has been studied only in a few countries. Here, we present the first retrospective study on the incidence of spider bites requiring hospital care in Spain, compared to bites or stings from snakes, hymenopterans, and scorpions. Using ICD9MC and ICD10 databases from the World Health Organization’s International Classification of Diseases for the period 1997–2020, we quantified the cases of envenomation by spiders, compared to those by other terrestrial toxic animals, the demographic data of envenomation cases, the relative severity of spider bites, and the geographic distribution of envenomation cases. Overall, the incidence of acute intoxication by terrestrial toxic animals in Spain was ca. 1.23 cases per million inhabitants. In decreasing order of importance, cases were due to snakes, hymenopterans, spiders, scorpions, and myriapods. Fatal cases were extremely rare, caused mainly by hymenopterans. No fatalities were caused by spiders, scorpions, and myriapods. A greater incidence of snake bites occurred in northern Spain, but no geographical trends were found for spider bites or scorpion stings. Severe poisoning or life-threatening cases due to bites or stings from toxic terrestrial animals in Spain seems to be very low, especially for spiders, compared to other countries in the world. In general, spiders do not present a risk to human health and should not be considered a major driver of morbidity.
