Two dangerous scorpion species, Leiurus quinquestriatus and Androctonus aeneas, cause severe envenomations in Niger. The study highlights the need to test existing antivenoms for Androctonus aeneas due to its high toxicity.

Area of Science:

  • Toxicology
  • Zoology
  • Public Health

Context:

  • Severe human envenomations in Niger are linked to two scorpion species.
  • Leiurus quinquestriatus is abundant, while Androctonus aeneas is less frequent.
  • Androctonus aeneas is newly documented in a Sahel country, previously known only in North Africa.

Purpose:

  • To identify the scorpion species responsible for severe envenomations in Niger.
  • To assess the venom toxicity of Androctonus aeneas in comparison to other dangerous African scorpions.
  • To address the lack of a specific antivenom for Androctonus aeneas.

Summary:

  • Leiurus quinquestriatus and Androctonus aeneas are identified as key envenomating scorpions in Niger.
  • Androctonus aeneas venom exhibits high toxicity, comparable to other medically significant Androctonus species.

  • Existing antivenoms for related species may offer paraspecific neutralization, requiring further investigation.

    • Impact:

    • Informs public health strategies for scorpion sting management in Niger and the Sahel region.
    • Highlights the urgent need for developing or validating antivenoms for Androctonus aeneas.
    • Contributes to understanding scorpion biodiversity and medical entomology in North and West Africa.
