Abstract：
Sporotrichosis is an implantation mycosis with subcutaneo-lymphatic or, more rarely, a viscerally disseminated affection; it can be acquired through traumatic percutaneous inoculation of the fungus present in soil or plant matter, or by feline scratching. Among the causative agents, Sporothrix brasiliensis is considered the most virulent species with a high prevalence in Brazil and recently in Argentina.
OBJECTIVE: To describe a S. brasiliensis outbreak in domestic and feral cats detected in the Magallanes region of southern Chile.
METHODS: Between the months of July and September 2022, three cats presented with suppurative subcutaneous lesions located mainly on the head and thoracic limbs. The cytology revealed the presence of yeasts with morphological characteristics suggestive of Sporothrix spp. The histopathology confirmed pyogranulomatous subcutaneous lesions associated with the presence of the same yeasts. The fungal culture followed by the partial gene sequence and analysis of the ITS region confirmed the diagnosis of the S. brasiliensis as the causative agent. The cats were treated with itraconazole associated in one case with potassium iodide. The evolution of the patients was favorable in all cases.
CONCLUSIONS: An outbreak caused by S. brasiliensis was detected in domestic and feral cats in austral Chile. The correct identification of this fungus and antifungigram is essential for treatment decisions and for designing dissemination control and prevention programs under a one health approach that consider the health of people, animals, and the environment.

摘要：
孢子丝菌病是一种植入性真菌病，伴有皮下淋巴或，很少,内脏传播的影响；它可以通过对土壤或植物中存在的真菌进行创伤性经皮接种来获得，或者是猫科动物抓挠.在病原体中，巴西孢子丝菌被认为是最具毒力的物种，在巴西和最近在阿根廷的流行率很高。
目的：描述在智利南部的Magallanes地区发现的家猫和野猫中的巴西链球菌爆发。
方法：在2022年7月至9月之间，三只猫出现化脓性皮下病变，主要位于头部和胸肢。细胞学检查显示存在具有孢子丝菌形态特征的酵母。组织病理学证实与相同酵母的存在相关的脓性肉芽肿性皮下病变。真菌培养后的部分基因序列和ITS区域的分析证实了巴西链球菌作为病原体的诊断。在1例与碘化钾相关的情况下，用伊曲康唑治疗猫。在所有情况下，患者的发展都是有利的。
结论：在智利南方的家猫和野猫中发现了由巴西链球菌引起的暴发。这种真菌和抗真菌的正确识别对于治疗决策和在考虑人的健康的单一健康方法下设计传播控制和预防计划至关重要，动物,和环境。
