利用16S rRNA 测序方法,研究年龄、饮食、种类、地理位置等因素对哥伦比亚地区两种主要疟疾病原携带蚊(那尼按蚊和达林按蚊)的肠道菌群组成的影响;
蚊子的大多数肠道菌群是在幼虫期获得的,蚊子的发育时期对肠道菌群的影响最大, 其次是地理位置,而蚊子的种类和饮食影响力最小;
蚊子的肠道菌群可以帮助其抵抗环境细菌的入侵;
对蚊子肠道菌群组成的调节因素的深入研究,为病媒生物防除策略提供了参考依据。

Abstract:
BACKGROUND: The understanding of the roles of gut bacteria in the fitness and vectorial capacity of mosquitoes that transmit malaria, is improving; however, the factors shaping the composition and structure of such bacterial communities remain elusive. In this study, a high-throughput 16S rRNA gene sequencing was conducted to understand the effect of developmental stage, feeding status, species, and geography on the composition of the gut bacterial microbiota of two main Colombian malaria vectors, Anopheles nuneztovari and Anopheles darlingi.
RESULTS: The results revealed that mosquito developmental stage, followed by geographical location, are more important determinants of the gut bacterial composition than mosquito species or adult feeding status. Further, they showed that mosquito gut is a major filter for environmental bacteria colonization.
CONCLUSIONS: The sampling design and analytical approach of this study allowed to untangle the influence of factors that are simultaneously shaping the microbiota composition of two Latin-American malaria vectors, essential aspect for the design of vector biocontrol strategies.
