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.
■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。
