家兔(Oryctolaguscuniculus)通常作为宠物饲养或饲养进行实验室研究,肉,毛皮生产,或这些目的的组合。我们进行了一项回顾性研究,以根据目的评估家兔的疾病患病率。我们取回了尸检结果,活检,以及2013-2022年在加利福尼亚州4个诊断实验室收到的2,583例病例的细胞学。兔子被归类为宠物(2,241;86.8%),实验动物(92;3.6%),产肉动物(60;2.3%),或多用途动物(190;7.4%)。最终诊断为2,360例(91.4%),按系统分类,病因学,和过程类型。宠物兔的中位年龄最高(5.9岁;vs.3y,0.67y,和0.25y的肉,多用途,实验室兔子,分别),并且大多数肿瘤在该组中被诊断出(研究中总共896个肿瘤中的872个;97.3%),皮肤肿瘤,女性生殖道,血液淋巴系统是最常见的。实验室兔子的感染性肠囊炎患病率很高(92只中有40只;43.4%),这些病例中约有45%是由于机会性大肠杆菌病。传染性和寄生性肺炎在肉兔中很常见(60中的18例;30%);肺炎巴氏杆菌病占这些病例的60%以上。传染性胆管炎在多用途兔子中很常见(110中的61;55.5%),兔出血性疾病是最常见的病因(占这些病例的82.4%)。我们的结果表明,使用目的可以预测提交诊断实验室的兔子的疾病患病率。
Domestic rabbits (Oryctolagus cuniculus) are commonly kept as pets or bred for
laboratory investigation, meat, fur production, or a combination of these purposes. We conducted a retrospective study to assess the prevalence of diseases in domestic rabbits according to purpose. We retrieved results of autopsies, biopsies, and cytologies from 2,583 cases received at 4 diagnostic laboratories in California from 2013-2022. Rabbits were classified as pets (2,241; 86.8%),
laboratory animals (92; 3.6%), meat-production animals (60; 2.3%), or multipurpose animals (190; 7.4%). A final diagnosis was reached in 2,360 (91.4%) cases and was classified by system, etiology, and type of process. Pet rabbits had the highest median age (5.9 y; vs. 3 y, 0.67 y, and 0.25 y in meat, multipurpose, and
laboratory rabbits, respectively), and most of the neoplasms were diagnosed in this group (872 of the total 896 neoplasms in the study; 97.3%), with tumors of the skin, female reproductive tract, and hematolymphoid system being the most common.
Laboratory rabbits had a high prevalence of infectious enterotyphlocolitis (40 of 92; 43.4%), and ~45% of those cases were due to opportunistic colibacillosis. Infectious and parasitic pneumonias were common in meat rabbits (18 of 60; 30%); pneumonic pasteurellosis accounted for >60% of those cases. Infectious cholangiohepatitides were common in multipurpose rabbits (61 of 110; 55.5%), with rabbit hemorrhagic disease representing the most common etiology (82.4% of those cases). Our results demonstrate that purpose of use can predict prevalence of disease in rabbits submitted to diagnostic laboratories.
