A 2019 study conducted in Puerto Rico showed that the 95th percentile for the time until the loss of Zika virus RNA detection was 54 days in serum, 34 days in urine, and 81 days in semen. (medscape.com)

To better understand the extent of fitness costs of the T242N mutation and the repair of fitness loss through compensatory amino acids, we investigated its fitness impact in different transmitted/founder (T/F) viruses. (ox.ac.uk)

XMRV was identified using a viral detection DNA microarray composed of oligonucleotides corresponding to the most conserved sequences of all known viruses (1). (phoenixrising.me)

RESULTS: The T242N mutation resulted in various levels of fitness loss in four different T/F viruses. (ox.ac.uk)
Expression of the lhNef hairpin within the HIV-1 genome results in potent trans-inhibition of wild-type HIV-1. (biomedcentral.com)

Trans-complementation of the HIV-1 NL4-3 IN D116N virus with mutant IN molecules restored particle release to levels comparable to WT IN (red), partially restored particle release (gray) or could not restore particle release (blue). (elifesciences.org)

Blood and any body fluid visibly contaminated with blood should be considered capable of transmitting hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). (medscape.com)
Patients coinfected with HBV and hepatitis D virus (HDV) have a greater risk of HCC and cirrhosis. (researchsquare.com)
The current study was undertaken to assess HDV genotype distribution and determine clinical characteristics of hepatitis delta virus (HDV) among HBsAg positive individuals in Shanghai. (researchsquare.com)
The global epidemiology of Hepatitis C Virus (HCV) may be roughly described by two groups of genotypes: the worldwide distributed ones (subtypes 1a, 1b, 2a and 3a, among others) and the endemic ones (subtypes 4a, 5a, 6a, among others). (cdc.gov)

Human immunodeficiency virus type 1 (HIV-1) can be inhibited by means of RNA silencing or interference (RNAi) using synthetic short interfering RNAs (siRNAs) or gene constructs encoding short hairpin RNAs (shRNAs) or long hairpin RNAs (lhRNAs). (biomedcentral.com)
Traditional phenotypic assays selleck chemicals used to assess the susceptibility of mutant human immunodeficiency virus type-1 (HIV-1) obtained from infected patients or from resistance selection to antiviral agents in cell culture are rather tedious and time consuming. (mdmpathway.com)

Some of the earliest characterized whole-genome HIV-1 sequences were collected in Zaire, currently called the Democratic Republic of the Congo (DRC), in the late 1970s and early 1980s. (cdc.gov)
