Affected horses had gradual hair loss of the mane and tail and endocrine dermatosis after grazing for three months during the dry season on a paddock invaded by the plant. The main histological lesions include compact ortho-keratotic hyperkeratosis and numerous flame follicles. Toxicological analysis by HPLC-UV demonstrated 0.8 mg/g of mimosine in the leaves. © 2024 Published by Elsevier Ltd.  aAlopecia  aAraguari  aMimosa pudica  aMimosine  aPLATAFORMA DE INVESTIGACIÓN EN SALUD ANIMAL - INIA  aPoisonous plants1 aQUEIROZ-MACHADO, C.R.R.1 aQUEIROZ, F.1 aGARDNER, D.R.1 aRIET-CORREA, F.  tToxicon, 2024, Volume 247, 107844. https://doi.org/10.1016/j.toxicon.2024.107844
