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, is considered the most virulent species with a high prevalence in Brazil and recently in Argentina.
To describe a outbreak in domestic and feral cats detected in the Magallanes region of southern Chile.
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 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 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.
An outbreak caused by 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.
孢子丝菌病是一种植入性真菌病，可引起皮下淋巴管感染，或更罕见的内脏播散性感染；它可通过皮肤创伤接种土壤或植物中的真菌，或通过猫抓感染。在病原体中，被认为是最具致病性的物种，在巴西以及最近在阿根廷都有很高的发病率。
描述在智利南部麦哲伦地区检测到的家猫和野猫中的疫情爆发情况。
在2022年7月至9月期间，三只猫出现了主要位于头部和胸肢的化脓性皮下病变。细胞学检查发现存在具有提示为申克孢子丝菌形态特征的酵母。组织病理学证实了与相同酵母存在相关的化脓性肉芽肿性皮下病变。真菌培养后进行ITS区域的部分基因序列分析，确诊申克孢子丝菌为病原体。这些猫用伊曲康唑治疗，其中一例联合碘化钾。所有病例患者的病情发展都很顺利。
在智利南部的家猫和野猫中检测到由申克孢子丝菌引起的疫情爆发。正确识别这种真菌并进行药敏试验对于治疗决策以及在考虑人类、动物和环境健康的“同一健康”方法下设计传播控制和预防计划至关重要。
