Homologous recombination between different species of alphaherpesviruses has been described between herpes simplex viruses 1 and 2 but has not yet been observed between other alphaherpesviruses. In the present study we chose to assess to what extent in vitro recombination can occur between members of a well-defined group of closely related viruses such as ruminant alphaherpesviruses. At 24 h af...
HIV-1 prevalence in Guangxi, China, has been growing since 1996, when the first case was reported. Over half of HIV-1 positive patients in Guangxi Province were injecting drug users (IDUs), possibly because of the province's location near drug-trafficking routes. Since a phase II HIV vaccine trial is ongoing there, a current characterization of the subtypes of HIV-1 among IDUs in Guangxi would ...
Global HIV-1 surveillance has led to the detection of its new recombinant forms. This study was carried out for the first time to elucidate the genetic characterization and evolutionary relationship of HIV-1 strains among injecting drug users of Nagaland, northeastern India. A total of 156 injecting drug users participated in this study voluntarily. Among them 18 were seropositive for HIV-1 (11...
Genetic recombination is an important mechanism for increasing diversity of RNA viruses, and constitutes a viral escape mechanism to host immune responses and to treatment with antiviral compounds. Although rare, epidemiologically important hepatitis C virus (HCV) recombinants have been reported. In addition, recombination is an important regulatory mechanism of cytopathogenicity for the relate...
Currently, data on HIV-1 circulating strains among men who have sex with men (MSM) in Argentina is scarce. In South America, the distribution and the prevalence of BF recombinants are dissimilar and exhibit an underappreciated heterogeneity of recombinant structures. Here, we studied for the first time the genetic diversity of HIV-1 BF recombinants and their evolution over time through in-depth...
A complication in the analysis of the role of ICP34.5 gene in the herpes simplex virus type-1 (HSV-1) lifecycle is the presence of overlapping antisense gene, open reading frame P (ORF P), which is also deleted in HSV-1 ICP34.5 negative mutants. A HSV-1 wild type strain (17) ICP34.5/ORF P deletion mutant (1716) is totally avirulent in animal models and impaired in a number of in vitro functions...
