A giant virus in a small lake: characterization of a new tropical algal virus expands the geographical and genetic diversity of the Brazilian virosphere

Journal of Virology
Chloroviruses are large double-stranded DNA (dsDNA) viruses that infect Chlorella-like green algae in freshwater environments. Despite being extensively studied in the Northern Hemisphere, little is known about their diversity and biology in tropical ...

Faustovirus E12 Transcriptome Analysis Reveals Complex Splicing in Capsid Gene

Frontiers in Microbiology, 2018
Faustoviruses are the first giant viruses of amoebae isolated on Vermamoeba vermiformis. They are distantly related to African swine fever virus, the causative agent of lethal hemorrhagic fever in domestic pigs. Structural studies have shown the presence

The proteomics of the giant cedratvirus particles reveals unique and shared features with pitho-like viruses

Journal of Virology
Cedratvirus is a giant virus belonging to the order Pimascovirales, a group that includes other viruses such as pithoviruses and orpheoviruses. Cedratviruses infect Acanthamoeba castellanii and have a genome of ~600 kb, encoding ~800 predicted proteins ...

Acanthamoeba polyphaga mimivirus Virophage Seroconversion in Travelers Returning from Laos

Emerging Infectious Diseases, 2012
During January 2010, a husband and wife returned from Laos to France with probable parasitic disease. Increased antibodies against an Acanthamoeba polyphaga mimivirus virophage indicated seroconversion. While in Laos, they had eaten raw fish, a potential

Virophages of Giant Viruses: An Update at Eleven

Viruses, 2019
The last decade has been marked by two eminent discoveries that have changed our perception of the virology field: The discovery of giant viruses and a distinct new class of viral agents that parasitize their viral factories, the virophages.

Continuous year-round isolation of giant viruses from brackish shoreline soils

Frontiers in Microbiology
Giant viruses, categorized under Nucleocytoviricota, are believed to exist ubiquitously in natural environments. However, comprehensive reports on isolated giant viruses remain scarce, with limited information available on unrecoverable strains, viral ...

Gram-Positive Bacteria-Like DNA Binding Machineries Involved in Replication Initiation and Termination Mechanisms of Mimivirus

Viruses, 2019
The detailed mechanisms of replication initiation, termination and segregation events were not yet known in Acanthamoeba polyphaga mimivirus (APMV). Here, we show detailed bioinformatics-based analyses of chromosomal replication in APMV from initiation ...

Usurpativirus massiliensis, a new giant virus related to clandestinovirus

Virology Journal
Giant virus discovery in 2003 revolutionized the virus paradigm. In 2015, we introduced a new host, Vermamoeba vermiformis, that led to the discovery of Faustovirus, Orpheovirus and two giant viruses (Clandestinovirus and a faustovirus) having distinct ...
