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

To be transmitted by its mosquito vector, dengue virus (DENV) must infect midgut epithelial cells, replicate and disseminate into the hemocoel, and finally infect the salivary glands, which is essential for transmission.

The outer shell of the papillomavirus particle is comprised of 72 pentamers of the major capsid L1 protein arranged on a T = 7 icosahedral lattice.

Interaction between Bluetongue virus outer capsid protein VP2 and vimentin is necessary for virus egress

In this study it is demonstrated that BTV VP2 associates with vimentin in both virus infected cells and in the absence of other viral proteins.

Oral ulcer as an unusual feature of visceral leishmaniasis in an AIDS patient

Human immunodeficiency virus (HIV) infection is increasing worldwide, and several reports indicate a rising trend of VL / HIV co-infection, modifying the traditional anthroponotic pattern of VL transmission.
