Global genetic diversity of Aedes aegypti
Mosquitoes, especially Aedes aegypti, are becoming important models for studying invasion biology. We characterized genetic variation at 12 microsatellite loci in 79 populations of Ae. aegypti from 30 countries in six ...
Evaluación de la resistencia a insecticidas en cepas de Aedes aegypti (Diptera Culicidae) de la Región Caribe de Costa Rica
Evaluation of insecticide resistance in strains of Aedes aegypti (Diptera: Culicidae) from the Caribbean region of Costa Rica
Introducción: el dengue y chikungunya son virosis antroponóticas transmitidas por Aedes aegypti que afectan extensas áreas del continente americano incluyendo Costa Rica. La reciente introducción del virus Zika representa ...
Zika Virus (ZIKV): A New Emerging Pathogen Transmitted by Aedes Mosquitoes (Diptera: Culicidae) in the Latin American Subcontinent
Aedes aegypti and Aedes albopictus (Diptera: Culicidae) are two species of synanthropic mosquitoes that are common in outdoor and indoor domiciliary environments in tropical countries. Their vectorial competence and ...
Exposure of dogs to spotted fever group rickettsiae in urban sites associated with human rickettsioses in Costa Rica
The zoonotic transmission cycles of Rickettsia rickettsii and other spotted fever group (SFG) rickettsiae in Latin America have usually been associated with rural or sylvatic environments, although domestic dogs can be ...
Detection of rickettsiae in fleas and ticks from areas of Costa Rica with history of spotted fever group rickettsioses
Outbreaks of spotted fevers have been reported in Costa Rica since the 1950s, although vectors responsible for transmission to humans have not been directly identified. In this study, species of Rickettsia were detected ...
Reevaluación de los índices larvales para Aedes aegypti (Diptera: Culicidae) en dos localidades con historia epidemiológica de dengue, Costa Rica
Reevaluation of the larval índices for Aedes aegypti (Diptera: Culicidae) in two localities with an epidemiological histoy of dengue, Costa Rica
Introducción. En Costa Rica, el dengue es la principal enfermedad de trasmisión vectorial. Esta afecta ecosistema urbanos como La Carpio y La Gran Puntarenas, donde Aedes aegypti es altamente prevalente. Objetivo. Reevaluar ...
Evaluation of predictive maps for Aedes aegypti larval habitats in two urban areas of Costa Rica
The abundance of Aedes aegypti can be associated with urban structure and tree cover, which conceals and protects containers. The purpose of this study was to create and evaluate predictive maps for Ae. Aegypti larval ...
Modeling dengue cases in health Regions of Costa Rica using El Niño Southern Oscillation and local vegetation dynamics
Temporal behavior of dengue fever and dengue hemorrhagic fever (DH/DHF) has been associated with climate, which may modulate mosquito vector populations. El Niño Southern Oscillation (ENSO) fluctuations can be related to ...
Associations between urban structure and Aedes aegypti larval habitats in Puntarenas, Costa Rica
Geospatial technologies have been increasingly applied to study vector-borne diseases, although their use in urban setting has been limited. In this study, high-resolution satellite imagery from QuickBird was analyzed to ...
Mapping the risk of Aedes aegypti larval habitats using tree cover in Puntarenas, Costa Rica
Tree cover and other characteristics of urban structure have been associated in urban environments with abundance and productivity of Aedes aegypti and other mosquito larval habitats. Tree cover can conceal containers, ...
