Abstract：
UNASSIGNED: Respiratory diseases, including the multifactorial \"swine respiratory disease complex,\" have a significant impact on swine production. Recently, a condition manifesting primarily in the trachea, known as hemorrhagic tracheitis syndrome (HTS), has been described in pigs. HTS is characterized by severe coughing and high mortality in finishing pigs.
UNASSIGNED: This report presents the first case of HTS in an adult male pig from a Portuguese farm. The animal died without any previous clinical signs. Necropsy revealed significant thickening of the trachea. Fibrinous necrotic hemorrhagic tracheitis was identified through histopathological analysis, but no bacterial infectious agents were detected during microbiological examination.
UNASSIGNED: This case underscores the need for comprehensive research, including systematic necropsies and histopathological assessments, to understand the actual prevalence of the disease, elucidate the etiology, and develop effective interventions for HTS in swine productions.

摘要：
■呼吸系统疾病，包括多因素的“猪呼吸道疾病复合体”，“对养猪生产有重大影响。最近,一种主要表现在气管中的疾病，被称为出血性支气管炎综合征（HTS），在猪中描述过。HTS的特征在于在育肥猪中严重咳嗽和高死亡率。
■本报告介绍了第一例来自葡萄牙农场的成年公猪的HTS病例。该动物在没有任何先前的临床体征的情况下死亡。尸检显示气管明显增厚。通过组织病理学分析确定了纤维坏死性出血性支气管炎，但是在微生物检查中没有检测到细菌感染因子。
■这个案例强调了全面研究的必要性，包括系统尸检和组织病理学评估，为了了解这种疾病的实际患病率，阐明病因，并为猪生产中的HTS制定有效的干预措施。
