Viruses are obligate parasites of Eukarya, Archaea and Bacteria. Acanthamoeba polyphaga mimivirus (APMV) is the largest known virus; it grows only in amoeba and is visible under the optical microscope. Mimivirus possesses a 1,185-kilobase double-stranded linear chromosome whose coding capacity is greater than that of numerous bacteria and archaea1, 2, 3.(More)
BACKGROUND Antiretroviral preexposure prophylaxis has been shown to reduce the risk of human immunodeficiency virus type 1 (HIV-1) infection in some studies, but conflicting results have been reported among studies, probably due to challenges of adherence to a daily regimen. METHODS We conducted a double-blind, randomized trial of antiretroviral therapy(More)
Giant viruses such as Mimivirus isolated from amoeba found in aquatic habitats show biological sophistication comparable to that of simple cellular life forms and seem to evolve by similar mechanisms, including extensive gene duplication and horizontal gene transfer (HGT), possibly in part through a viral parasite, the virophage. We report here the(More)
Mimivirus is the largest known virus whose genome and physical size are comparable to some small bacteria, blurring the boundary between a virus and a cell. Structural studies of Mimivirus have been difficult because of its size and long surface fibers. Here we report the use of enzymatic digestions to remove the surface fibers of Mimivirus in order to(More)
We recently described a giant double stranded DNA virus called Mimivirus, isolated from amoebae, which might represent a new pneumonia-associated human pathogen. Its unique morphological and genomic characteristics allowed us to propose Mimivirus as a member of a new distinct Nucleocytoplasmic Large DNA viruses family, the Mimiviridae. Mimivirus-specific(More)
Acanthamoeba polyphaga Mimivirus is a giant double-stranded DNA virus defining a new genus, the Mimiviridae, among the Nucleo-Cytoplasmic Large DNA Viruses (NCLDV). We used utrastructural studies to shed light on the different steps of the Mimivirus replication cycle: entry via phagocytosis, release of viral DNA into the cell cytoplasm through fusion of(More)
In recent years, France has witnessed both structural changes in the population of people living with HIV and a relative improvement in the social representation of HIV infection. However, potential changes in people's day-to-day experience with HIV have not been documented. We used data from the national surveys ANRS-VESPA (2003) and VESPA2 (2011) to(More)
Encouraging HIV-positive people to disclose their serostatus to their main partner is considered as a key component of secondary prevention. The purpose of this study was to identify individual and structural factors associated with HIV serostatus disclosure to one's steady partner in Cameroon, a country which has implemented a large program for access to(More)
OBJECTIVES HIV-infected men who have sex with men (HIV-MSM) are at high risk of hepatitis C virus (HCV) infection. This study aimed to compare risk factors between HIV-MSM coinfected with HCV and those who are not, in a national representative survey conducted in France. METHODS The ANRS VESPA2 survey (April 2011-January 2012) collected sociodemographic(More)
To determine whether systemic immunization with plasmid DNA and virus vector against visna/maedi virus (VMV) would induce protective immune responses, sheep were immunized with VMV gag and/or env sequences using particle-mediated epidermal bombardment and injection of recombinant modified vaccinia Ankara. The results showed that immunization induced both(More)
