Trypanosomes were observed in 38% of blood smears from southern brown bandicoots (Isoodon obesulus) and in 10% of blood smears from eastern barred bandicoots (Perameles gunnii). This is the first record of such hemoparasites in Tasmanian marsupials. There appeared to be a statistically significant size difference between trypanosomes found in the 2 bandicoot species, suggesting the possibility of 2 distinct species of parasite. There appears to be a distinction between the trypanosomes found in our temperate Isoodon species and the tropical bandicoot. Isoodon macrurus. The use of the microhematocrit method provided an effective means for concentrating trypanosomes, whereas image analysis was a more effective method than the ocular micrometer for obtaining accurate measurements.
在38%的南褐袋狸（Isoodon obesulus）血涂片和10%的东袋狸（Perameles gunnii）血涂片中观察到了锥虫。这是此类血液寄生虫在塔斯马尼亚有袋动物中的首次记录。在这两种袋狸物种中发现的锥虫在统计学上似乎存在显著的大小差异，这表明可能存在两种不同的寄生虫物种。在我们温带的Isoodon物种中发现的锥虫与热带袋狸Isoodon macrurus中的锥虫似乎有所不同。微量血细胞比容法为浓缩锥虫提供了一种有效的方法，而图像分析是一种比目镜测微计更有效的获取准确测量值的方法。
