“…The arenaviruses that occur in North America include Tamiami (TAM) in southern Florida; 1,2 Whitewater Arroyo (WWA) in northwestern New Mexico; 3 and lymphocytic choriomeningitis (LCM), 4 an Old World virus that probably was introduced into the Americas in recent times. Sigmodon hispidus (a cotton rat) is the principal host of TAM virus, 1,2 Neotoma albigula (the white-throated woodrat) is a natural host of WWA virus, 3 and Mus musculus (the house mouse) is the principal host of LCM virus. 4 The family Arenaviridae comprises 2 serocomplexes: the Old World (LCM-Lassa) complex and the New World (Tacaribe) complex.…”

They are WWAV and BBTV isolated from white-throated wood rats (Neotoma albigula) in New Mexico in 1993 and in Arizona, respectively (15,20); AV96010151 and SKTV isolated from Mexican wood rats (Neotoma mexicana) in New Mexico and in Arizona, respectively (22,37); BCNV isolated from California mice (Peromyscus californi- (18,19). Pseudoviruses containing GPC molecules from clade B viruses TCRV and AMAV were included as positive controls, and the one harboring the G protein of vesicular stomatitis virus (VSV) was used as a negative control for the ability to use TfR1.…”

“…These viruses are most closely related to clade B in their entry glycoproteins (GPC) (5), whereas their nucleoproteins (NP) are more closely related to those of clade A viruses. The first recorded North American arenavirus is Tamiami virus (TAMV), which was isolated from hispid cottons rats (Sigmodon hispidus) in southern Florida in 1970 (18,19). Subsequently, Whitewater Arroyo virus (WWAV) was isolated in 1993 in northwestern New Mexico from white-throated wood rats (Neotoma albigula) (20).…”

At least five New World (NW) arenaviruses cause hemorrhagic fevers in South America. These pathogenic clade B viruses, as well as nonpathogenic arenaviruses of the same clade, use transferrin receptor 1 (TfR1) of their host species to enter cells. Pathogenic viruses are distinguished from closely related nonpathogenic ones by their additional ability to utilize human TfR1 (hTfR1). Here, we investigate the receptor usage of North American arenaviruses, whose entry proteins share greatest similarity with those of the clade B viruses. We show that all six North American arenaviruses investigated utilize host species TfR1 orthologs and present evidence consistent with arenavirus-mediated selection pressure on the TfR1 of the North American arenavirus host species. Notably, one of these viruses, AV96010151, closely related to the prototype Whitewater Arroyo virus (WWAV), entered cells using hTfR1, consistent with a role for a WWAV-like virus in three fatal human infections whose causative agent has not been identified. In addition, modest changes were sufficient to convert hTfR1 into a functional receptor for most of these viruses, suggesting that a minor alteration in virus entry protein may allow these viruses to use hTfR1. Our data establish TfR1 as a cellular receptor for North American arenaviruses, highlight an "arms race" between these viruses and their host species, support the association of North American arenavirus with fatal human infections, and suggest that these viruses have a higher potential to emerge and cause human diseases than has previously been appreciated. IMPORTANCEhTfR1 use is a key determinant for a NW arenavirus to cause hemorrhagic fevers in humans. All known pathogenic NW arenaviruses are transmitted in South America by their host rodents. North American arenaviruses are generally considered nonpathogenic, but some of these viruses have been tentatively implicated in human fatalities. We show that these North American arenaviruses use the TfR1 orthologs of their rodent host species and identify TfR1 polymorphisms suggesting an ongoing "arms race" between these viruses and their hosts. We also show that a close relative of a North American arenavirus suggested to have caused human fatalities, the Whitewater Arroyo species complex virus AV96010151, uses human TfR1. Moreover, we present data that imply that modest changes in other North American arenaviruses might allow these viruses to infect humans. Collectively, our data suggest that North American arenaviruses have a higher potential to cause human disease than previously assumed.

“…In nature, MACV was found to be carried by big lauchas (Calomys callosus) [73]. In the following years, the "Tacaribe antigenic group" expanded to include additional newly discovered viruses: Amaparí (AMAV) [109], Latino (LATV, first mentioned in reference [101]), Paraná (PARV) [139], Pichindé (PICV) [133], and Tamiami viruses (TAMV) [36]. None of these viruses are known to cause human disease (although there are anecdotal reports of two severe PICV infections in humans), but all of them were found to be maintained in nature by specific rodent hosts.…”

Until recently, members of the monogeneric family Arenaviridae (arenaviruses) have been known to infect only muroid rodents and, in one case, possibly phyllostomid bats. The paradigm of arenaviruses exclusively infecting small mammals shifted dramatically when several groups independently published the detection and isolation of a divergent group of arenaviruses in captive alethinophidian snakes. Preliminary phylogenetic analyses suggest that these reptilian arenaviruses constitute a sister clade to mammalian arenaviruses. Here, the members of the International Committee on Taxonomy of Viruses (ICTV) Arenaviridae Study Group, together with other experts, outline the taxonomic reorganization of the family Arenaviridae to accommodate reptilian arenaviruses and other recently discovered mammalian arenaviruses and to improve compliance with the Rules of the International Code of Virus Classification and Nomenclature (ICVCN). PAirwise Sequence Comparison (PASC) of arenavirus genomes and NP amino acid pairwise distances support the modification of the present classification. As a result, the current genus Arenavirus is replaced by two genera, Mammarenavirus and Reptarenavirus, which are established to accommodate mammalian and reptilian arenaviruses, respectively, in the same family. The current species landscape among mammalian arenaviruses is upheld, with two new species added for Lunk and Merino Walk viruses and minor corrections to the spelling of some names. The published snake arenaviruses are distributed among three new separate reptarenavirus species. Finally, a non-Latinized binomial species name scheme is adopted for all arenavirus species. In addition, the current virus abbreviations have been evaluated, and some changes are 123Arch Virol (2015) 160:1851-1874 DOI 10.1007/s00705-015-2418 introduced to unequivocally identify each virus in electronic databases, manuscripts, and oral proceedings.
