Clinical Effects of the Immunization Protocol Using Loxosceles Venom in Naïve Horses

Toxins, 2022
Bites of brown spiders (Loxosceles spp.) are responsible for dermonecrotic lesions and potentially systemic envenoming that can lead to death. The only effective therapy is the use of the antivenom, usually produced in horses.
