Sporothrix brasiliensis in cats from Santiago, Chile

María Carolina Escobar et al. Med Mycol Case Rep. .

Abstract

We report Sporothrix brasiliensis infection in three cats from Santiago, Chile. Recently, S. brasiliensis was reported in cats from the southernmost region of Chile located 2,190 km from Santiago. Our findings emphasize the emergence of S. brasiliensis in the Chilean context, reflecting its rapid expansion across South America in recent years. Veterinarians should include S. brasiliensis in the differential diagnosis of skin conditions in cats.

Sporothrix brasiliensis lesions in a cat (case A). A) Gross (clinical) image showing multifocal to coalescing ulcerative and exudative skin lesions on the head, face and neck. B) Fine needle aspirate and smear from one of the lesions described in A). Several fungal yeasts are seen in the cytoplasm of a macrophage and free in the background. These are oval (“cigar-shaped”), 3–5 μm in diameter and 5–9 μm in length, with a clear cell wall. May-Grünwald Giemsa stain. 500X original magnification. C) Low power histologic image of one of the skin lesions. These consist of a dense pyogranulomatous infiltrate that ulcerates the epidermis. Hematoxylin and Eosin. 100X original magnification. D) Yeasts are PAS positive and can be seen in the cytoplasm of macrophages and free between the inflammatory cells. Periodic acid-Schiff. Digital magnification of a 200X original image.
