Chagas disease is a neglected tropical disease caused by the parasite that is transmitted mainly by the feces of infected Triatomines. In Ecuador the main vector is which is distributed in several provinces of the country. More than 40% of these insects in the wild have as part of their intestinal microbiota. For this reason, the objective of this research was to characterize the intestinal bacterial microbiota of .
The methodology used was based on the DNA extraction of the intestinal contents from the wild collected insects (adults and nymphs V), as well as the insects maintained at the insectary of the CISeAL. Finally, the samples were analyzed by metagenomics extensions based on the different selected criteria.
The intestinal microbiota of presented a marked divergence between laboratory-raised and wild collected insects. This difference was observed in all stages and was similar between insects from Loja and Manabí. A large loss of microbial symbionts was observed in laboratory-raised insects.
This study is a crucial first step in investigating microbiota interactions and advancing new methodologies.
恰加斯病是一种被忽视的热带疾病,由寄生虫引起,主要通过受感染锥蝽的粪便传播。在厄瓜多尔,主要病媒是[具体病媒名称缺失],它分布在该国的几个省份。这些野生昆虫中超过40%的肠道微生物群中含有[具体微生物名称缺失]。因此,本研究的目的是对[具体昆虫名称缺失]的肠道细菌微生物群进行特征描述。
所使用的方法基于从野外采集的昆虫(成虫和若虫V)以及在CISeAL昆虫饲养室饲养的昆虫的肠道内容物中提取DNA。最后,根据不同的选定标准,通过宏基因组学扩展对样本进行分析。
[具体昆虫名称缺失]的肠道微生物群在实验室饲养的昆虫和野外采集的昆虫之间呈现出明显差异。在所有阶段都观察到了这种差异,并且来自洛哈和马纳比的昆虫之间的差异相似。在实验室饲养的昆虫中观察到大量微生物共生体的损失。
本研究是调查微生物群相互作用和推进新方法的关键第一步。
