Vector competence of Culex quinquefasciatus for Tembusu virus and viral factors for virus transmission by mosquitoes.
Article in Veterinary research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The ongoing epidemic of flaviviruses worldwide has underscored the importance of studying flavivirus vector competence, considering their close association with mosquito vectors. Tembusu virus is an avian-related mosquito-borne flavivirus that has been an epidemic in China and Southeast Asia since 2010. However, the reason for the outbreak of Tembusu virus in 2010 remains unclear, and it is unknown whether changes in vector transmission played an essential role in this process. To address these questions, we conducted a study using Culex quinquefasciatus as a model for Tembusu virus infection, employing both oral infection and microinjection methods. Our findings confirmed that both vertical and venereal transmission collectively contribute to the cycle of Tembusu virus within the mosquito population, with persistent infections observed. Importantly, our data revealed that the prototypical Tembusu virus MM_1775 strain exhibited significantly greater infectivity and transmission rates in mosquitoes than did the duck Tembusu virus (CQW1 strain). Furthermore, we revealed that the viral E protein and 3' untranslated region are key elements responsible for these differences. In conclusion, our study sheds light on mosquito transmission of Tembusu virus and provides valuable insights into the factors influencing its infectivity and transmission rates. These findings contribute to a better understanding of Tembusu virus epidemiology and can potentially aid in the development of strategies to control its spread.
