| serologic evidence of flavivirus infection in bats in the yucatan peninsula of mexico. | we captured 140 bats of seven species in merida city in the yucatan peninsula of mexico in 2010. serum was collected from each bat and assayed by plaque reduction neutralization test (prnt) using six flaviviruses: west nile virus, st. louis encephalitis virus, and dengue viruses 1-4. flavivirus-specific antibodies were detected in 26 bats (19%). the antibody-positive bats belonged to three species: the pallas's long-tongued bat (glossophaga soricina), jamaican fruit bat (artibeus jamaicensis), a ... | 0 | 23778622 |
| introduction of the american/asian genotype of dengue 2 virus into the yucatan state of mexico. | a dengue (den) outbreak occurred in the yucatan state of mexico in 2002. three isolates were obtained from patients presenting with den-like symptoms, and examined by partial nucleotide sequencing and phylogenetic analysis. the isolates were identified as den-2 viruses of the american-asian genotype; this is the first report of this genotype in the yucatan state. the den-2 viruses of the american-asian genotype have been associated with more severe disease outcomes. thus, its introduction into t ... | 2004 | 15516647 |
| variation in vector competence for dengue 2 virus among 24 collections of aedes aegypti from mexico and the united states. | aedes aegypti from 24 collections in mexico and the united states were challenged orally with dengue 2 virus jam1409 (den-2 jam1409). the vector competence (vc) of the populations ranged from 24% to 83%. mosquito populations from the yucatan exhibited greater vc than those from other areas of mexico. the presence or absence of a midgut infection barrier (mib) and a midgut escape barrier (meb) was determined for mosquitoes in each population. the percentage of mosquitoes exhibiting an mib ranged ... | 2002 | 12363070 |
