(1) Background: spp. are zoonotic bacteria with small mammals as main reservoirs. spp. prevalence in small mammals from Myanmar and Sri Lanka are yet unknown. (2) Methods: Small mammals were snap trapped in Sri Lanka and Myanmar in urban surroundings. Spleens-derived DNA was screened for spp. using conventional PCR based on three target genes. Positive samples were sequenced. (3) Results: 994 small mammals were collected comprising 6 species: , , , and . In Myanmar, the prevalence in Bandicoot rats (68.47%) was higher than in (41.67%), (21.33%), and (3.64%). Furthermore the prevalence in Myanmar (34%, = 495) was twice as high as in Sri Lanka (16%, = 499). In Sri Lanka, spp. occurred almost exclusively in . In Myanmar, was mainly detected (56%), followed by sp. KM2529 (15%), sp. SE-Bart D (12%) and (1%). In Sri Lanka, (60%) and sp. KM2581 (33%) were predominant. (4) Conclusions: spp. were detected in all investigated small mammal species from Myanmar and Sri Lanka for the first time. and are zoonotic. As these small mammals originated from urban settlements, human bartonellosis seems likely to occur.
(1) 背景：巴尔通体属细菌是一种人畜共患病菌，主要宿主为小型哺乳动物。缅甸和斯里兰卡小型哺乳动物中巴尔通体属细菌的流行情况尚不清楚。(2) 方法：在斯里兰卡和缅甸的城市环境中用陷阱捕捉小型哺乳动物。基于三个靶基因，采用常规聚合酶链反应（PCR）对脾脏来源的DNA进行巴尔通体属细菌筛查。对阳性样本进行测序。(3) 结果：共收集994只小型哺乳动物，分属6个物种：板齿鼠、黄毛鼠、屋顶鼠、斯氏家鼠、臭鼩鼱和长尾大麝鼩。在缅甸，板齿鼠中巴尔通体属细菌的流行率（68.47%）高于黄毛鼠（41.67%）、屋顶鼠（21.33%）和斯氏家鼠（3.64%）。此外，缅甸的流行率（34%，n = 495）是斯里兰卡（16%，n = 499）的两倍。在斯里兰卡，巴尔通体属细菌几乎只出现在斯氏家鼠中。在缅甸，主要检测到五日热巴尔通体（56%），其次是巴尔通体sp. KM2529（15%）、巴尔通体sp. SE - Bart D（12%）和汉赛巴尔通体（1%）。在斯里兰卡，五日热巴尔通体（60%）和巴尔通体sp. KM2581（33%）占主导地位。(4) 结论：首次在缅甸和斯里兰卡所有调查的小型哺乳动物物种中检测到巴尔通体属细菌。五日热巴尔通体和汉赛巴尔通体是人畜共患病菌。由于这些小型哺乳动物来自城市居民区，人类巴尔通体病似乎有可能发生。
