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.

New pandemics: HIV and AIDS, HCV and chronic hepatitis, Influenza virus and flu
New pandemics are a serious threat to the health of the entire world. They are essentially of viral origin and spread at large speed.

Molecular analysis of hepatitis B virus "a" determinant in asymptomatic and symptomatic Mexican carriers
Hepatitis B virus (HBV) is a small DNA-containing virus with 4 genes, C, S, X and P.

The PB1-F2 protein of Influenza A virus: increasing pathogenicity by disrupting alveolar macrophages
With the prospect of another pandemic Influenza fresh in our consciousness, the pathogenic nature of the Influenza A virus and its ability to induce high rates of mortality are ever more pertinent.

Zebularine reactivates silenced E-cadherin but unlike 5-Azacytidine does not induce switching from latent to lytic Epstein-Barr virus infection in Burkitt's lymphoma Akata cells
Epigenetic silencing of regulatory genes by aberrant methylation contributes to tumorigenesis.

Quantitative analysis of Nipah virus proteins released as virus-like particles reveals central role for the matrix protein
Nipah virus (NiV) is an emerging paramyxovirus distinguished by its ability to cause fatal disease in both animal and human hosts.

Structure-based engineering of papillomavirus major capsid L1: controlling particle assembly
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.

HSV-2- and HIV-1- permissive cell lines co-infected by HSV-2 and HIV-1 co-replicate HSV-2 and HIV-1 without production of HSV-2/HIV-1 pseudotype particles
In the study, the authors investigated whether HIV-1 and HSV-2 may interact at the cellular level by forming HIV-1 hybrid virions pseudotyped with HSV-2 envelope glycoproteins, as was previously reported for HSV type 1.

More than 3% of world population is infected with hepatitis C virus (HCV).

Hepatitis E in Europe -- are pigs or pork the problem?
Hepatitis E virus infections can be fatal in pregnant women, but until recently doctors thought the disease was confined to China, India and developing countries.
