Researchers have discovered an unusually small virus in a lake in Brazil.
- The virus has been named Yaravirus after ‘Yara’, a water-queen figure in Brazilian mythology.
- It was found in Lake Pampulha, an artificial lagoon in the city of Belo Horizonte
- Researchers found that more than 90 percent of the Yarvirus’ genes had never been identified in other viruses.
- The new virus — which is only 80 nanometers in diameter, or about 0.1% the thickness of a human hair — has the ability to infect other amoebas.
- The Yaravirus does not infect human cells.
- DNA viruses are classified based on the protein that makes up their shell, or capsid. The Yaravirus’ capsid doesn’t resemble any previously known protein.
