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.

TL;DR: Although epizootic VEEV strains are opportunistic in their use of mosquito vectors, the most widespread outbreaks appear to involve specific adaptation to Ochlerotatus taeniorhynchus, themost common vector in many coastal areas.

TL;DR: Findings suggest that the epidemic in Venezuela during 1995 resulted from the re-emergence of an epizootic serotype IC VEE virus, and raises the possibility of a serotypes IC enzootic transmission cycle in northern Venezuela.

TL;DR: The relatively high prevalence of L. chagasi infection found among D. marsupialis captured near human dwellings suggests that these animals may be an important peridomestic reservoir.

TL;DR: A total of 340 Leishmania strains, isolated from humans, animals, and sand flies from various regions of Colombia, were examined by isozyme electrophoresis and indicated that the populations of these 2 species are genetically very similar.
