Journal ArticleDOI
Origins of dengue type 2 viruses associated with increased pathogenicity in the Americas.
Rebeca Rico-Hesse,Lisa M. Harrison,Rosa Alba Salas,Duilia Tovar,Ananda Nisalak,Celso Ramos,Jorge Boshell,Maria Teresa R. de Mesa,Rita Maria Ribeiro Nogueira,Amelia P.A. Travassos Da Rosa +9 more
TL;DR: Phylogenetic analyses suggest that these genotypes of dengue type 2 virus originated in Southeast Asia and that they displaced the native, American genotype in at least four countries, and vaccination and other control efforts should therefore be directed at decreasing the transmission of these "virulent" genotypes.
Journal ArticleDOI
Dengue Virus Structural Differences That Correlate with Pathogenesis
Katrin C. Leitmeyer,David W. Vaughn,Douglas M. Watts,Rosalba Salas,Iris Villalobos,de Chacon,Celso Ramos,Rebeca Rico-Hesse +7 more
TL;DR: A method for comparing dengue type 2 genomes (reverse transcriptase PCR in six fragments) directly from patient plasma is developed to better reflect the true composition of viral RNA populations in the natural host and permit their association with pathogenesis.
Journal ArticleDOI
Genetic diversity of hantaviruses in Mexico: identification of three novel hantaviruses from Neotominae rodents.
Hiroaki Kariwa,Haruka Yoshida,Cornelio Sánchez-Hernández,María de Lourdes Romero-Almaraz,José Alberto Almazán-Catalán,Celso Ramos,Daisuke Miyashita,Takahiro Seto,Ayako Takano,Masashi Totani,Ryo Murata,Ngonda Saasa,Mariko Ishizuka,Takahiro Sanada,Kentaro Yoshii,Kumiko Yoshimatsu,Jiro Arikawa,Ikuo Takashima +17 more
TL;DR: Phylogenetic analysis revealed that the MTN, CAR, and HUI viruses occupy a monophyletic clade with the LSC, ELMC, and Rio Segundo viruses, which are harbored by Peromyscus boylii, R. megalotis, and Reithrodontomys mexicanus, respectively.
Journal ArticleDOI
Ecology of hantaviruses in Mexico: genetic identification of rodent host species and spillover infection.
Ngonda Saasa,Cornelio Sánchez-Hernández,María de Lourdes Romero-Almaraz,Ezequiel Guerrero-Ibarra,Alberto Almazán-Catalán,Haruka Yoshida,Daisuke Miyashita,Mariko Ishizuka,Takahiro Sanada,Takahiro Seto,Kentaro Yoshii,Celso Ramos,Kumiko Yoshimatsu,Jiro Arikawa,Ikuo Takashima,Hiroaki Kariwa +15 more
TL;DR: Nucleotide sequence and phylogenetic analysis showed that MTNV and CARV were primarily carried by P. beatae and R. sumichrasti, respectively, suggesting active transmission and/or spillover infections within sympatric rodent species.
Journal ArticleDOI
The N-terminus of the Montano virus nucleocapsid protein possesses broadly cross-reactive conformation-dependent epitopes conserved in rodent-borne hantaviruses.
Ngonda Saasa,Haruka Yoshida,Kenta Shimizu,Cornelio Sánchez-Hernández,María de Lourdes Romero-Almaraz,Takaaki Koma,Takahiro Sanada,Takahiro Seto,Kentaro Yoshii,Celso Ramos,Kumiko Yoshimatsu,Jiro Arikawa,Ikuo Takashima,Hiroaki Kariwa +13 more
TL;DR: It is suggested that discontinuous epitopes at the N-terminus are conserved, at least in rodent-borne hantaviruses, and that they contribute considerably to N protein cross-reactivity.
