Evidence of venom variability associated with venom extraction interval in the monocled cobra (Naja kaouthia)

  Evidence of venom variability associated with venom extraction interval in the monocled cobra (Naja kaouthia) Abstract Snake venom variability is a critical factor in antivenom production. Although several influencing factors have been studied, the impact of extraction interval on venom properties remains poorly understood. This study evaluated the effects of various extraction intervals on venom yield, the percentage of dry weight (%Dw), and composition in the monocled cobra ( Naja kaouthia ). Twenty-five captive snakes were randomly allocated to five groups, each undergoing a control extraction followed by a repeated extraction at 1, 4, 7, 10, or 14 days. Venom profiles were characterized using reversed-phase high-performance liquid chromatography (RP-HPLC) and Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). Results indicated that while fresh venom yield remained stable across all intervals, %Dw significantly decreased in extractions performed between 1 and 10 days, ...

Overview of the scorpion fauna of Morocco (Arachnida: Scorpiones)

Abstract
Morocco hosts one of the most abundant and diverse scorpion faunas in North Africa and the Mediterranean region. This scorpion fauna is notable for marked endemism and medical significance, as it encompasses species confirmed to pose a danger to humans. The present study serves as a synthesis of the knowledge gathered regarding the inventory of this scorpion fauna from previously published works. The current checklist of this scorpion fauna includes 68 species and subspecies distributed across 12 genera and two families.
