Abstract

Cardiomyopathies have been increasingly noted in the captive population of Livingstone's fruit bat ( Pteropus livingstonii ). The aim of this study was to produce a set of repeatable quantitative reference measurements that could be used to assess the cardiac size during radiographic examination of this species. Ventro-dorsal and lateral radiographs (n = 129) from a total of 42 individual Livingstone's fruit bats were examined. The control group radiographs (n = 102) consisted of 34 healthy individuals. Radiographic measurements were taken of structures within the thorax and then converted into ratios. These ratios from radiographs (n = 27) were also calculated for eight individuals with diagnosed cardiomyopathy. Vertebral Heart Scores (VHS) were calculated from right lateral radiographs and compared between the two groups. From all the data, only the width of the cardiac silhouette to the width of the thorax (the W : T ratio) in the ventro-dorsal view and the VHS were found to be significantly different between both groups (P < 0.05). The group with cardiomyopathies had a mean W : T ratio of 0.59 (±0.005) and a VHS of 9.77 (±0.89), while a mean W : T ratio of 0.54 (±0.004) and a VHS of 8.71 (±0.93) was established for healthy specimens.

摘要

在圈养的利文斯通果蝠（Pteropus livingstonii）种群中，心肌病越来越多地被发现。本研究的目的是生成一组可重复的定量参考测量值，用于在对该物种进行放射检查时评估心脏大小。对总共42只利文斯通果蝠的腹背位和侧位X线片（n = 129）进行了检查。对照组X线片（n = 102）由34只健康个体组成。对胸部结构进行了放射学测量，然后将其转换为比率。还计算了8例诊断为心肌病的个体的X线片（n = 27）的这些比率。从右侧位X线片计算出脊椎心脏评分（VHS），并在两组之间进行比较。从所有数据中发现，两组之间仅腹背位视图中心脏轮廓宽度与胸部宽度之比（W∶T比）和VHS有显著差异（P < 0.05）。患有心肌病的组的平均W∶T比为0.59（±0.005），VHS为9.77（±0.89），而健康标本的平均W∶T比为0.54（±0.004），VHS为8.71（±0.93）。
