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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
A review of the genus Rickettsia in Central America
In this paper, we present a historical review of rickettsiosis in Central America and also the most recent findings of Rickettsia in ectoparasites. All countries of Central America have records of rickettsiosis. Regarding ...
Spotted fever group Rickettsiae in Ticks from Missouri
Tick-borne rickettsioses pose a major health threat among vector-borne infections in Missouri but there are some uncertainties regarding the vector competence and range of tick species, as well as the virulence of certain ...
Cimex lectularius Linnaeus, 1758 (Hemiptera: Cimicidae) in Costa Rica: First Case Report Confirmed by Molecular Methods in Central America
Cimex lectularius and Cimex hemipterus are the most common species of bedbugs that infest homes. Although case reports decreased substantially by the end of the 20th century, bed bugs, and especially C. lectularius, are ...
Exposure of dogs to Rickettsia spp. in Costa Rica: Risk factors for PCR-positive ectoparasites and seropositivity
Infection of dogs with Rickettsia spp. can result in inapparent, mild, or severe disease. Moreover, common dog ticks and fleas are able to transmit rickettsiae to nearby humans. In this study, the seroprevalence of spotted ...
