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).

大胡子龙 ( Pogona vitticeps)是宠物爬行动物贸易和动物收藏中的常见物种。尽管如此，仅发表了一些详述常见死亡原因的评论。这项回顾性研究的目的是在几个私人和一个动物收藏中收集与胡须龙中各种疾病的存在和流行有关的信息。根据死亡或安乐死的原因以及受影响的器官系统，对 36 只动物的尸体进行了 20 年的尸检，结果进行了分类。在一组动物（n = 12；33.33%）中确定了多个导致死亡的因素，并被计算在一个以上的类别中。按类别划分的最常见的死亡原因是炎症（传染性或非传染性）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或病症最常导致死亡。最常见的组织学发现包括肝脏脂肪变化、肾小管上皮色素沉着和存在小窝透明样物质。尽管卡方检验没有揭示这些常见发现与合并症之间的关联，但在慢性/退行性死亡原因与肾小管上皮色素之间发现了统计学上显着的关联。分类变量的卡方检验，包括导致死亡的因素、受影响的主要器官、性别、年龄等级和机构，确定了男性与慢性/退行性疾病之间的统计学显着关联。最常见的组织学发现包括肝脏脂肪变化、肾小管上皮色素沉着和存在小窝透明样物质。尽管卡方检验没有揭示这些常见发现与合并症之间的关联，但在慢性/退行性死亡原因与肾小管上皮色素之间发现了统计学上显着的关联。分类变量的卡方检验，包括导致死亡的因素、受影响的主要器官、性别、年龄等级和机构，确定了男性与慢性/退行性疾病之间的统计学显着关联。最常见的组织学发现包括肝脏脂肪变化、肾小管上皮色素沉着和存在小窝透明样物质。尽管卡方检验没有揭示这些常见发现与合并症之间的关联，但在慢性/退行性死亡原因与肾小管上皮色素之间发现了统计学上显着的关联。分类变量的卡方检验，包括导致死亡的因素、受影响的主要器官、性别、年龄等级和机构，确定了男性与慢性/退行性疾病之间具有统计学意义的关联。尽管卡方检验没有揭示这些常见发现与合并症之间的关联，但在慢性/退行性死亡原因与肾小管上皮色素之间发现了统计学上显着的关联。分类变量的卡方检验，包括导致死亡的因素、受影响的主要器官、性别、年龄等级和机构，确定了男性与慢性/退行性疾病之间的统计学显着关联。尽管卡方检验没有揭示这些常见发现与合并症之间的关联，但在慢性/退行性死亡原因与肾小管上皮色素之间发现了统计学上显着的关联。分类变量的卡方检验，包括导致死亡的因素、受影响的主要器官、性别、年龄等级和机构，确定了男性与慢性/退行性疾病之间的统计学显着关联。P  = 0.043）和导致死亡和私人收藏动物的炎症因素（P  = 0.039）。在 1-5 岁和 >5 岁年龄段中，炎症因素导致的死亡显着更高（P  = 0.02）。
