Structural and functional comparison of toxins from the venom of the scorpions Centruroides infamatus infamatus, centruroides limpidus limpidus and Centruroides noxius [PDF]
Comparative Biochemistry and Physiology - B Biochemistry and Molecular Biology, 1996 Two novel toxins containing 66 amino acid residues each were isolated from the venom of the scorpions Centruroides infamatus infamatus and Centruroides limpidus limpidus, respectively. Their full amino acid sequences were determined. Comparison of primary structures showed that they share 97% similarity among themselves and 83% to that of toxin 2 from ...

Envenomation by Centruroides pococki scorpion with neuromuscular toxicity [PDF]
Toxicon, 2021 Cases of human envenomation by Centruroides pococki are exceptionally reported in human. We report a Class III human envenomation by C. pococki in Guadeloupe, French West Indies, with neuromuscular toxicity that has never been described before. Symptoms resolved within a few hours, without the need for intravenous scorpion-specific antivenom.

Treatments for Centruroides exilicauda Envenomation
Archives of Pediatrics & Adolescent Medicine, 1984We treated two cases of severe envenomation by the scorpion Centruroides exilicauda. The first infant was treated with a species-specific scorpion antivenom, which produced a delayed but dramatic return of all vital signs to normal. A second infant was treated with two doses of intravenous propranolol hydrochloride and had a rapid, dramatic decrease in

Envenomation by the Scorpion Centruroides Sculpturatus
Journal of Toxicology: Clinical Toxicology, 1983Envenomation by the scorpion C. sculpturatus can be life threatening. The action of the venom is to produce prolonged and excessive firing of neuronal axons which results in a wide variety of signs and symptoms. Records of 670 patients suffering from scorpion stings in central Arizona in 1982 were reviewed to characterize the clinical course of these ...

What's eating you? bark scorpions (Centruroides exilicauda and Centruroides sculpturatus).
Cutis, 2021Centruroides is a common genus of bark scorpions in the United States with at least 21 species considered to be medically important, including the closely related Centruroides exilicauda and Centruroides sculpturatus. Stings from C exilicauda and C sculpturatus have been shown to cause fatality in children more often than in adults.

Reproductive investiment in the scorpion Centruroides vittatus
Oecologia, 1993Among invertebrates, scorpions possess a relatively unique set of reproductive traits. The interrelationships of these traits may have important implications for life history theory, yet there have been few studies of these traits in scorpions. Our data indicate that larger female Centruroides vittatus produce more offspring and have a higher total ...

Incidence of Immediate and Delayed Hypersensitivity to Centruroides Antivenom
Annals of Emergency Medicine, 1999To assess the incidence and course of immediate and delayed hypersensitivity to Centruroides antivenom.We performed a 12-month prospective observation study, with telephone follow-up, evaluating the incidence of anaphylaxis or anaphylactoid reactions and serum sickness after Centruroides antivenom administration.

Atropine Use inCentruroidesScorpion Envenomation
Journal of Toxicology: Clinical Toxicology, 2001Systemic scorpion envenomation may be associated with hypersalivation and respiratory distress. Atropine can dry secretions, but is not recommended for stings from many foreign scorpions, since it exacerbates adrenergic toxicity to the cardiopulmonary system. Serious adrenergic effects, however, are rare with Centruroides sculpturatus envenomation.Five

Abstract Margatoxin (MgTX) and noxiustoxin (NxTX) are 39 amino acid peptides which share with charybdotoxin (ChTX) significant sequence homology and such structural motifs as three disulfide bridges, a mid-chain {a-helix), and a C terminal antiparallel β-sheet. MgTX and NxTX comprise the best-studied members of a second class of scorpion
