A: Maximum parsimony phylogenetic tree B: Distance-based phylogenetic
tree. The tree was built under the Tamura-Nei model of DNA substitution
with estimation of the shape parameter of the gamma distribution (
28
). This model and the associated parameters resulted from testing
our dataset with the program MODELTEST 3.06 (
26
). Both trees include Argentinean and Uruguayan hantaviruses from
hantavirus pulmonary syndrome (HPS) case-patients and rodents.
Hantavirus sequences from HPS case-patients in Uruguay: Ac1Hu, Ca2Hu,
Bu3Hu, Pe4Hu, Uru1/97, Uru1/99. Hantavirus sequences from yellow pygmy
rice rats: U89, Sa63, Ce20, Ce22. Sin Nombre virus was used as
outgroup.*Specimens deposited at the Specimen Collection of the
Sección Zoología Vertebrados, Facultad de
Ciencias, Universidad de la República, Montevideo, Uruguay,
with the following numbers: U89=ZVC-M2154, SA63=ZVC-M2155,
Ce20=ZVC-M2156, Ce22=ZVC-M2157, and Ce155=ZVC-M2158.
