“…Scorpion stings pose a significant medical problem worldwide, particularly in the Middle East, North Africa, India, the Americas, Brazil, and Trinidad [3]. There are 24 scorpion species, distributed throughout the Kingdom of Saudi Arabia [4,5]. The most severe lethal effects of scorpion envenomation include neurotoxicity and cardiotoxicity.…”

Summary. We present the comprehensive chromatographic profiles of three scorpion species, Androctonus crassicauda, Androctonus bicolor, and Leiurus quinquestriatus, commonly inhabited to Middle East regions. Their venoms were milked by electrical stimulation, diluted with distilled water, properly mixed and centrifuged to separate the mucus from venom. The clear supernatant was filtered and the protein concentration was determined. Pre-diluted venoms were chromatographed on FPLC (fast protein liquid chromatography) and RP-HPLC (reversed-phase high-performance liquid chromatography) and the fractions were collected for molecular weight determination. Both techniques have resulted clearly distinguishable chromatographic patterns that can be used for identification of scorpion species and having a quick indication of venom toxicity.

Currently, medically significant scorpion species belong to the Buthidae family and are represented by the genera Androctonus, Buthus, Mesobuthus, Hottentotta, Parabuthus, Tityus, Centruroides, Leiurus. Although Leiurus was originally considered a monotypic genus, four additional species have since been described. Leiurus abdullahbayrami (previously identified as L. quinquestriatus in Turkey) was classified as a new Leiurus species. This is the first report conducted on the lethality and biologic effects of L. abdullahbayrami scorpion venom in mice. In this study, the electrophoretic protein pattern of its venom was also determined. Two protein bands with molecular masses of 4 and 6 kDa were more strongly detected than other protein bands in the venom sample. Electrophoresis showed that L. abdullahbayrami scorpion venom possesses both short-and long-chain neurotoxins. The median lethal dose of this venom was found to be 0.19 mg/kg by subcutaneous (SC) injection in mice. Animals experimentally envenomed with L. abdullahbayrami venom exhibited hyperexcitability, agitation, aggressive behavior, squeaking and fighting, tachypnea, weakness, convulsions, and death due to cardiac and respiratory failure. In further studies, the potency of antivenom should be investigated in relation to the scorpion venom. Molecular and pharmacological studies are also required to identify and characterize L. abdullahbayrami scorpion venom.

“…Hendrixson (2006) studied the systematics of the buthid scorpion faunal composition, with notes on two other families in the Kingdom of Saudi Arabia. Several studies have contributed significantly to the knowledge about the scorpion sting syndrome (Al-Asmari, et al, 2007;Al-Sadoon & Al-Farraj, 2008;Jarrar and Al-Rowaily 2008) geographical distribution, scorpion identification and composition (Al-Asmari, et al, 2009a, b;Al-Asmari, et al, 2013; Diversity, scorpion fauna, southwestern part of Saudi Arabia…”
