The bearded dragon (Pogona vitticeps) is a common species in the pet reptile trade and in zoological collections. Despite this, only a few reviews detailing common causes of mortality have been published. The goal of this retrospective study was to compile information related to the presence and prevalence of various diseases in bearded dragons in several private and one zoological collection. Findings from 36 animals, necropsied over a 20-year period were categorized on the basis of the cause of death or euthanasia and the organ system affected. Multiple contributors to death were identified in a subset of animals (n = 12; 33.33%) and were counted in more than one category. The most common contributors to death by category were inflammatory (infectious or non-infectious) diseases (n = 25; 69.44%), followed by chronic/degenerative diseases (n = 17; 47.22%). Diseases or conditions that were systemic, or affected the hepatobiliary system, were the most commonly implicated in death. The most frequent histological findings included hepatic fatty change, renal tubular epithelial pigmentation and the presence of faveolar hyaline-like material. Although Chi square testing did not reveal an association between these common findings and comorbidities, a statistically significant association was found between chronic/degenerative causes of death and renal tubular epithelial pigment. Chi square testing of categorical variables, including contributors to death, primary organ(s) affected, sex, age class and institution, identified statistically significant associations between males and chronic/degenerative disease (P = 0.043) and inflammatory contributors to death and private collection animals (P = 0.039). Death due to inflammatory contributors was significantly higher in the 1-5-year-old and >5-year-old age classes (P = 0.02).
鬃狮蜥（Pogona vitticeps）是宠物爬行动物贸易和动物园收藏中的常见物种。尽管如此，只有少数几篇详细介绍常见死亡原因的综述已经发表。本回顾性研究的目的是汇总有关几种私人和一家动物园收藏中鬃狮蜥各种疾病的存在和流行情况的信息。在 20 年的时间里，对 36 只动物进行尸检的结果基于死亡或安乐死的原因以及受影响的器官系统进行了分类。在一部分动物（n=12；33.33%）中确定了多个导致死亡的因素，并被归入多个类别。按类别分类，导致死亡的最常见因素是炎症（感染或非感染）性疾病（n=25；69.44%），其次是慢性/退行性疾病（n=17；47.22%）。全身性疾病或影响肝胆系统的疾病最常与死亡有关。最常见的组织学发现包括肝脂肪变性、肾小管上皮色素沉着和泡状透明样物质的存在。尽管卡方检验未显示这些常见发现与合并症之间存在关联，但在慢性/退行性死亡原因与肾小管上皮色素沉着之间发现了统计学上的显著关联。对包括死亡原因、主要受影响器官、性别、年龄组和机构在内的分类变量进行卡方检验，发现雄性与慢性/退行性疾病之间存在统计学显著关联（P=0.043），炎症性死亡原因与私人收藏动物之间存在统计学显著关联（P=0.039）。1-5 岁和>5 岁年龄组因炎症性死亡原因导致的死亡率明显更高（P=0.02）。
