摘要

摘要:在这项回顾性研究中,描述了巴西东北部犬猫真菌病的临床和解剖病理结果。在研究期间,对6827例伴侣动物的组织病理学检查(4090例尸检和2737例活检)进行了回顾,其中54例被诊断为真菌感染。其中,32例诊断为猫,22例诊断为狗。孢子菌病是最常见的真菌病(19/54),其次是皮肤真菌病(9/54)、隐球菌病(8/54)、念珠菌病(7/54)和褐丝酵母菌病(4/54)。其他疾病包括曲霉病、毛霉病和组织浆菌病各2例,而球孢子菌病各1例。通过常规和特殊的组织化学染色,通过与病原体的组织形态学特征相关的显微镜病变来诊断真菌病。偶有免疫组织化学和微生物培养证实。这项回顾性研究表明,尽管不常见,但真菌疾病是该地区狗和猫死亡的重要原因,猫是受影响最严重的物种,孢子虫病是最普遍的真菌病。临床体征与感染进入门静脉有关,伴有局部或弥散性浅、深皮肤病变或影响实质器官,尤其是全身性感染。镜下病变主要表现为脓肉芽肿性炎症伴真菌结构。在狗中,真菌病的发生主要是由于犬瘟热病毒合并感染后继发的免疫损伤。

Fungal diseases in dogs and cats in Northeastern Brazil
ABSTRACT: In this retrospective study, the clinical and anatomopathological findings of fungal diseases in dogs and cats in Northeastern Brazil are described. During the study period, 6,827 histopathological examinations (4,090 necropsies and 2,737 biopsies) of companion animals were reviewed, and fungal infections were diagnosed in 54 cases. Of these, 32 cases were diagnosed in cats and 22 in dogs. Sporotrichosis was the most prevalent mycosis (19/54), followed by dermatophytosis (9/54), cryptococcosis (8/54), candidiasis (7/54), and phaeohyphomycosis (4/54). Other diseases had two cases each, including aspergillosis, mucormycosis, and histoplasmosis, whereas coccidioidomycosis occurred once. Mycoses were diagnosed through microscopic lesions associated with the histomorphological characteristics of the agent, as evidenced by routine and special histochemical stains. They were occasionally confirmed by immunohistochemistry and microbiological cultivation. This retrospective study showed that despite being uncommon, fungal diseases are important causes of death in dogs and cats in the region, with cats being the most affected species and sporotrichosis being the most prevalent mycosis. Clinical signs were correlated with the portal of entry of the infection associated with localized or disseminated superficial and deep skin lesions or affecting parenchymal organs, especially in systemic infections. Microscopic lesions were mainly characterized by pyogranulomatous inflammation associated with fungal structures. In dogs, mycoses occurred mainly owing to an immunological impairment secondary to canine distemper virus co-infection.
