1. Juquitiba-like Hantavirus from 2 Nonrelated Rodent Species, Uruguay

Author

Adriana Delfraro, Lorena Tomé, Guillermo D’Elía, Mario Clara, Federico Achával, José C. Russi, and Juan Arbiza

Subjects
Hantavirus, Oligoryzomys, Oxymycterus, Sigmodontinae, Uruguay, dispatch, Medicine, Infectious and parasitic diseases, RC109-216
Abstract

Serologic and genetic analyses indicate that a Juquitiba-like hantavirus circulates in Maldonado, Uruguay. This virus is carried by 2 rodent species, Oligoryzomys nigripes and Oxymycterus nasutus. The same hantavirus in 2 nonrelated species can be explained by a spillover infection or a host-switching event.

2. Yellow Pygmy Rice Rat (Oligoryzomys flavescens) and Hantavirus Pulmonary Syndrome in Uruguay

Author

Adriana Delfraro, Mario Clara, Lorena Tomé, Federico Achaval, Silvana Levis, Gladys Calderón, Delia Enria, Mario Lozano, José Russi, and Juan Arbiza

Subjects
hantavirus, reservoir host, Oligoryzomys flavescens, Uruguay, research, Medicine, Infectious and parasitic diseases, RC109-216
Abstract

During 5,230 trapping nights, 672 small mammals were trapped in the areas where most hantavirus pulmonary syndrome (HPS) cases occur in Uruguay. Yellow pygmy rice rats (Oligoryzomys flavescens) were the only rodents that showed evidence of antibodies to hantavirus, with a seroprevalence of 2.6%. The rodents were trapped in all the explored environments, and most of the seropositive rodents were found in habitats frequented by humans. Nucleotide sequences were obtained from four HPS case-patients and four yellow pygmy rice rats of the M genome segment. Sequence comparison and phylogenetic analysis showed that rodent-borne viruses and viruses from three HPS case-patients form a well-supported clade and share a 96.4% identity with the previously characterized Central Plata hantavirus. These results suggest that yellow pygmy rice rat (O. flavescens) may be the host for Central Plata, a hantavirus associated with HPS in the southern area of Uruguay.[
