Conclusion

- Dengue virus type 2: replication and tropisms in orally infected Aedes aegypti mosquitoes

The results with the recently colonized Chetumal mosquitoes indicate that the EIP for DENVs may be shorter than the commonly reported, which could have important epidemiological consequences in dengue transmission. The mosquito tracheal system appears implicated in virus dissemination from the midgut, and viral infection in the vector is differentially modulated in different organs. DENV-2 exhibits differences in certain tissue tropisms in its vector in comparison to other arboviruses in their respective vectors.
