analysis of hantavirus genetic diversity in argentina: s segment-derived phylogeny. | nucleotide sequences were determined for the complete s genome segments of the six distinct hantavirus genotypes from argentina and for two cell culture-isolated andes virus strains from chile. phylogenetic analysis indicates that, although divergent from each other, all argentinian hantavirus genotypes group together and form a novel phylogenetic clade with the andes virus. the previously characterized south american hantaviruses laguna negra virus and rio mamore virus make up another clade tha ... | 2002 | 11907216 |
characterization of hantaviruses circulating in central brazil. | in 2004, an outbreak of hcps in brazil made hantaviruses a national threat to the rural and urban population. during this outbreak, 164 cases were reported, and 18.3% of them occurred in the federal district. in this study, hantavirus genomic sequences were amplified from seven patients who resided in central brazil and then sequenced and compared to other hantavirus sequences. the complete s segment sequence, which is 1847 bases long and potentially encodes the 428 amino acid nucleocapsid prote ... | 2009 | 19103306 |
genetic evidence of hantavirus infections in wild rodents from northwestern colombia. | this report builds on recent serological evidence for the presence of hantavirus in northern colombia by providing sequence-specific and phylogenetic data of hantavirus infections in wild rodents. from august 2007 to august 2008, 354 rodent specimens representing four families were collected in the northwestern antioquia region of colombia. antibodies reactive to sin nombre virus and maciel virus antigens by igg enzyme-linked immunosorbent assay were found in 15 of 109 (14%) cherries cane rats ( ... | 2011 | 21284514 |
prevalence of antibody to hantaviruses in humans and rodents in the caribbean region of colombia determined using araraquara and maciel virus antigens. | we tested sera from 286 agricultural workers and 322 rodents in the department of córdoba, northeastern colombia, for antibodies against two hantaviruses. the sera were analysed by indirect elisa using the lysate of vero e6 cells infected with maciel virus (macv) or the n protein of araraquara virus (arav) as antigens for the detection of antibodies against hantaviruses. twenty-four human sera were igg positive using one or both antigens. we detected anti-macv igg antibodies in 10 sera (3.5%) an ... | 2013 | 23579795 |
