arenavirus

 [ah-re´nah-vi″rus]
any member of a family of spherical or pleomorphic RNA viruses containing host cell–derived ribonucleoproteins, including viruses that cause lassa fever and lymphocytic choriomeningitis; the natural hosts are rodents.

Any of a family of single-stranded RNA viruses that cause chronic infections in rodents and when transmitted to humans cause various hemorrhagic diseases, including Lassa fever.

Arenavirus

The single genus of the family Arenaviridae, which includes Lassa virus, lymphocytic choriomeningitis virus and the Tacaribe group of haemorrhagic fever (e.g., Junin, Machupo viruses).

arenavirus

Any of the family of Arenaviridae of viruses which includes those causing LASSA FEVER and LYMPHOCYTIC CHORIOMENINGITIS. The name derives from the sand-like appearance of the internal granules seen on electron microscopy.

The phylogeny was inferred using BEAST2 (https:// www.beast2.org/) with nucleotide sequences of full-length nucleoprotein (NP), glycoprotein precursor (GPC), and L and Z genes of the Togo strain in conjunction with representative sequences of Lassa virus and other Old World arenaviruses. The most stable reconstruction was obtained for the L gene with the Togo strain being placed in sister relationship with lineage II (all branches with posterior support values >0.97) (Figure).
