Habronemosis, also known as habronemiasis or habronematidosis, is a parasitic disease of equids caused by the larval stages of Habronematidae nematodes (Habronema muscae, Habronema microstoma, and Draschia megastoma) that are transmitted by muscid flies. The presence of aberrant infective larvae in the cutaneous and conjunctival tissues of these hosts results in granulomatous, exudative, and ulcerated lesions, also known as "summer sores." In this study, we present a retrospective analysis of habronemosis cases in horses from the municipality of Lages, located on the Santa Catarina Plateau, a region with high altitudes and a temperate climate that differs from regions of Brazil where such parasitosis usually occurs. The equids were examined from 2008 to 2020 at the Veterinary Hospital of Santa Catarina State University. Sixteen patients were diagnosed and treated using macrocyclic lactones and wound cleaning. Most cases were recorded in autumn in horses (10/16, 62.5%) over 15 years of age (11/16, 68.8%), and the lesions were more frequently located in the conjunctiva (11/16, 68.8%). In scientific dissemination media, this is the first report of habronemosis on the Santa Catarina Plateau, Brazil. This information will contribute to the diagnosis, treatment and prevention of skin diseases in horses in this region.
马胃蝇蛆病，又称马胃线虫病或马胃蝇蛆蚴病，是一种由胃蝇科线虫（马胃蝇、小胃蝇和大胃蝇）幼虫引起的马属动物寄生虫病，通过食蝇传播。这些宿主皮肤和结膜组织中异常的感染性幼虫导致肉芽肿性、渗出性和溃疡性病变，也称为“夏季溃疡”。在这项研究中，我们对来自圣卡塔琳娜高原拉热斯市的马胃蝇蛆病病例进行了回顾性分析，该地区海拔较高，气候温和，与巴西通常发生这种寄生虫病的地区不同。这些马从 2008 年至 2020 年在圣卡塔琳娜州立大学兽医医院进行了检查。16 例患者被诊断并使用大环内酯类药物和伤口清洁进行治疗。大多数病例发生在 15 岁以上的秋季（10/16，62.5%）（11/16，68.8%），病变更常位于结膜（11/16，68.8%）。在科学传播媒体中，这是巴西圣卡塔琳娜高原首例马胃蝇蛆病报告。这些信息将有助于该地区马皮肤病的诊断、治疗和预防。
