The Wildlife Conservation Society's Bronx Zoo has been housing and breeding slender-tailed cloud rats (Phleomys pallidus) since 1985. Records of 82 animals from 1985 to 2013 were reviewed for this study. The animals were kept successfully in small family groups with a single adult male, multiple adult females, and their offspring. Sexual maturity was noted at approximately 2 years of age and gestation length ranged from 52 to 55 days. Animals were fed a diet including a complete commercial pelleted feed, mixed greens, carrot or yam, mixed hard nuts, and locally sourced browse. Medical conditions requiring treatment in neonates were often fatal whereas most medical conditions in adults were survivable. The most common cause of morbidity and mortality in neonates was maternal neglect or trauma (42%, 5/12 antemortem problems; cause of death in 32%, 8/25). The most significant problems in adults were cryptococcal pneumonia and trauma. Cryptococcus sp. was the cause of death in 11 cases (34%, 11/32) and significant comorbidity in an additional three cases. Treatment with antifungal medications was attempted but was unsuccessful in four cases. Many cases of trauma were treated successfully with conservative management or limited intervention. In four cases, treatment was complicated by extensive self-mutilation after surgical repair of traumatic lesions, which resulted in death or euthanasia. Lymphoplasmacytic thyroiditis was a common postmortem finding in adults (95%, 21/22 for which the thyroid gland was examined histologically). It is unclear if thyroiditis resulted in functional hypothyroidism so the significance of this finding is undetermined.

细尾云鼠（Phleomys pallidus）的饲养、发病率和死亡率

自 1985 年以来，野生动物保护协会的布朗克斯动物园一直在饲养和繁殖细尾云鼠（Phleomys pallidus）。本研究审查了 1985 年至 2013 年间 82 只动物的记录。这些动物被成功地饲养在具有单个成年雄性、多个成年雌性及其后代的小家庭组中。在大约 2 岁时注意到性成熟，妊娠长度为 52 至 55 天。给动物喂食的食物包括完整的商业颗粒饲料、混合蔬菜、胡萝卜或山药、混合硬坚果和当地采购的食物。新生儿需要治疗的医疗状况通常是致命的，而成人的大多数医疗状况都是可以生存的。新生儿发病和死亡的最常见原因是母亲的疏忽或创伤（42%，5/12 的死前问题；32% 的死因，8/25）。成人最严重的问题是隐球菌性肺炎和创伤。隐球菌属 是 11 例 (34%, 11/32) 的死亡原因，另外 3 例是严重合并症。曾尝试使用抗真菌药物进行治疗，但在 4 例中均未成功。许多创伤病例通过保守治疗或有限干预成功治疗。在四个案例中，外伤性病变的手术修复后广泛的自残导致治疗复杂化，导致死亡或安乐死。淋巴浆细胞性甲状腺炎是成人常见的死后发现（95%，21/22 对甲状腺进行组织学检查）。目前尚不清楚甲状腺炎是否导致功能性甲状腺功能减退症，因此这一发现的意义尚不确定。成人最严重的问题是隐球菌性肺炎和创伤。隐球菌属 是 11 例 (34%, 11/32) 的死亡原因，另外 3 例是严重合并症。曾尝试使用抗真菌药物进行治疗，但在 4 例中均未成功。许多创伤病例通过保守治疗或有限干预得到成功治疗。在四个案例中，外伤性病变的手术修复后广泛的自残导致治疗复杂化，导致死亡或安乐死。淋巴浆细胞性甲状腺炎是成人常见的死后发现（95%，21/22 对甲状腺进行组织学检查）。目前尚不清楚甲状腺炎是否导致功能性甲状腺功能减退症，因此这一发现的意义尚不确定。成人最严重的问题是隐球菌性肺炎和创伤。隐球菌属 是 11 例 (34%, 11/32) 的死亡原因，另外 3 例是严重合并症。曾尝试使用抗真菌药物进行治疗，但在 4 例中均未成功。许多创伤病例通过保守治疗或有限干预成功治疗。在四个案例中，外伤性病变的手术修复后广泛的自残导致治疗复杂化，导致死亡或安乐死。淋巴浆细胞性甲状腺炎是成人常见的死后发现（95%，21/22 对甲状腺进行组织学检查）。目前尚不清楚甲状腺炎是否导致功能性甲状腺功能减退症，因此这一发现的意义尚不确定。
