Leishmania infantum was considered to be absent from Amapá until 2017 when canine infection was detected. However, there is a lack of knowledge about which reservoir species are involved in transmission in this region.
Between 2014 and 2016, 86 samples from wild mammals and 74 from domestic dogs were collected in Wajãpi Indigenous Territory and were tested for the presence of deoxyribonucleic acid (DNA) of Leishmania.
The DNA of Le. infantum was detected in two rodent samples, Dasyprocta sp. and Proechimys cuvieri.
This is the first evidence characterizing a sylvatic transmission cycle of Le. infantum in the State of Amapá.
直到 2017 年才发现犬类感染,此前莱什曼原虫被认为不存在于阿马帕州。然而,人们对该地区参与传播的储存宿主物种知之甚少。
2014 年至 2016 年,在瓦雅皮土著领地采集了 86 份野生哺乳动物样本和 74 份家犬样本,检测莱什曼原虫脱氧核糖核酸(DNA)的存在情况。
在两种啮齿动物样本(Dasyprocta sp. 和 Proechimys cuvieri)中检测到莱什曼原虫 DNA。
这是首次在阿马帕州证实莱什曼原虫的森林传播循环。
