Abstract
CASE REPORT
An adult female Australian little red flying fox (Pteropus scapulatus) presented with icterus and anaemia. Examination of a blood smear revealed numerous trypanosomes 20.4-30.8 µm long with tapered ends. Necropsy and histological findings were consistent with trypanosome infection of lymphoid tissue and intravascular haemolysis. Sequence and phylogenetic analysis demonstrated this trypanosome species to be genetically distinct and most similar to Trypanosoma minasense and Trypanosoma rangeli (with a genetic distance of 1% at the 18S rRNA locus for both).
CONCLUSION
To the authors' knowledge this is the first report of a trypanosome infection associated with clinical disease in bats.
摘要
病例报告
一只成年雌性澳大利亚小红狐蝠（Pteropus scapulatus）出现黄疸和贫血症状。血液涂片检查发现了许多长20.4 - 30.8微米、两端逐渐变细的锥虫。尸检和组织学检查结果与锥虫感染淋巴组织和血管内溶血相符。序列和系统发育分析表明，这种锥虫物种在基因上是独特的，与米纳斯锥虫（Trypanosoma minasense）和兰氏锥虫（Trypanosoma rangeli）最为相似（在18S rRNA基因座处两者的遗传距离均为1%）。
结论
据作者所知，这是首次报道与蝙蝠临床疾病相关的锥虫感染。
