The gut tracts of many animals are inhabited by a microbial community composed of bacteria, archaea, fungi, and viruses. The interplay among these inhabitants can have an impact on health and disease. Mosquitoes are no exception – replication of dengue virus in the gut tract is modulated by a fungus and a bacterium.
The TWiVome explores induction of antiviral responses by repeating patterns of capsids, and a fungus in the mosquito gut that aids dengue virus replication. <span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span><span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span>&lt;span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”&gt;&lt;/span&gt;&amp;lt;span …
The TWiVians present an imported case of yellow fever in New York City, and explain how a dengue virus subgenomic RNA disrupts immunity in mosquito salivary glands to increase virus replication.
