dengue 2 genotypes in the state of oaxaca, mexico.to genetically characterize dengue 2 (den-2) viruses in oaxaca, mexico, the c protein, and a portion of the prm protein genes of 8 isolates from the 2001 den epidemic were sequenced. the sequences were compared to those of prototype den-2 viruses from various parts of the world. phylogenetic analysis suggested that the 2001 isolates of den-2 were of the american/asian genotype and were most similar to the jamaica and venezuelan isolates mara3, lard1996 and lard1910. molecular analyses confirmed ...200616096709
evidence of vertical transmission of dengue virus in two endemic localities in the state of oaxaca, mexico.dengue virus is spread in tropical areas of the world and is the causative agent of dengue fever and dengue hemorrhagic fever. it is horizontally transmitted to humans by infected aedes mosquitoes, but it is also able to be vertically or transovarially transmitted to insect progeny.200717700030
specific genetic markers for detecting subtypes of dengue virus serotype-2 in isolates from the states of oaxaca and veracruz, mexico.dengue (den) is an infectious disease caused by the den virus (denv), which belongs to the flavivirus genus in the family flaviviridae. it has a (+) sense rna genome and is mainly transmitted to humans by the vector mosquito aedes aegypti. dengue fever (df) and dengue hemorrhagic fever (dhf) are caused by one of four closely related virus serotypes (denv-1, denv-2, denv-3 and denv-4). epidemiological and evolutionary studies have indicated that host and viral factors are involved in determining ...200818625078
multiple recombinants in two dengue virus, serotype-2 isolates from patients from oaxaca, mexico.dengue (den) is a serious cause of mortality and morbidity in the world including mexico, where the infection is endemic. one of the states with the highest rate of dengue cases is oaxaca. the cause of den is a positive-sense rna virus, the dengue virus (denv) that evolves rapidly increasing its variability due to the absence of a repair mechanism that leads to approximately one mutational event per genome replication; which results in enhancement of viral adaptation, including the escape from h ...200920003526
distribution of dengue cases in the state of oaxaca, mexico, during the period 2004-2006.dengue virus infection is an emergent viral disease and the most important transmitted by a vector worldwide. in mexico it has been an important public health problem since 1995 and oaxaca is one of the most affected states in the country.200919487157
