ESTRADA-COATES, Alejandro et al. Surgical management and immunotherapy of Pythium insidiosum in a horse: case report. Abanico vet [online]. 2021, vol.11, e305.  Epub Apr 04, 2022. ISSN 2448-6132.  https://doi.org/10.21929/abavet2021.44.

Equine cutaneous pythiosis is caused by the oomycete Pythium insidiosum, which generally produces rapidly progressive granulomatous ulcerative lesions on the distal parts of limbs and abdomen. It is a globally distributed disease with higher prevalence in tropical and subtropical regions. The objective of this case report was to describe granulomatous lesions with necrotic tissue and fibrin bloody exudate in the palpebral region of the left eye caused by Pythium insidiosum in a quarter horse mare in Veracruz State, Mexico. The diagnosis was based on the clinical characteristics of the lesion and histopathology. Due to the extent of lesions, surgical resection was performed in combination with immunotherapy. Treatment with immunotherapy proved to be an effective alternative to achieve complete resolution of skin lesions.

Keywords : Pythium insidiosum; pythiosis; equine; immunotherapy.
