Diversidad de mosquitos (Diptera: Culicidae) de Jarabacoa, República Dominicana
2019
En República Dominicana tienen especial interés, dada su gran relevancia médica, las enfermedades transmitidas por mosquitos. La presente investigación profundiza sobre la diversidad de los culícidos existentes en el municipio de Jarabacoa, a fin de actualizar la información sobre estos dípteros y sus principales sitios de cría, naturales y artificiales. Para tal cometido, se procedió a la búsqueda activa de formas preimaginales mediante la técnica del dipper; se utilizaron pipetas plásticas para muestrear en reservorios de pequeño tamaño. La identificación se llevó a cabo mediante la utilización de lupa binocular y microscopio, con la ayuda de claves taxonómicas específicas. Se capturaron …
Practices in research, surveillance and control of neglected tropical diseases by One Health approaches: A survey targeting scientists from French-sp…
2021
One health (OH) approaches have increasingly been used in the last decade in the fight against zoonotic neglected tropical diseases (NTDs). However, descriptions of such collaborations between the human, animal and environmental health sectors are still limited for French-speaking tropical countries. The objective of the current survey was to explore the diversity of OH experiences applied to research, surveillance and control of NTDs by scientists from French-speaking countries, and discuss their constraints and benefits. Six zoonotic NTDs were targeted: echinococcoses, trypanosomiases, leishmaniases, rabies, Taenia solium cysticercosis and leptospiroses. Invitations to fill in an online q…
SOUTH AMERICAN COLLABORATION IN SCIENTIFIC PUBLICATIONS ON LEISHMANIASIS: BIBLIOMETRIC ANALYSIS IN SCOPUS (2000-2011)
2014
Objetivos: Evaluar la producción y la red de colaboración de investigación sobre leishmaniasis en Sudamérica. Métodos: Se realizó un estudio bibliométrico usando la base de datos SCOPUS. La unidad de análisis fueron los artículos originales de investigación publicados desde el año 2000 hasta 2011, realizados sobre leishmaniasis y que incluyeron al menos un autor sudamericano. Se obtuvieron para cada artículo: nombre de la revista, idioma, año de publicación, número de autores, instituciones, países y otras variables. Resultados: 3174 artículos fueron publicados, 2.272 de ellos eran artículos originales. Se identificaron 1.160 firmas institucionales diferentes, 58 países y 398 revistas cient…
The transcriptome analysis of Strongyloides stercoralis L3i larvae reveals targets for intervention in a neglected disease.
2012
Background: Strongyloidiasis is one of the most neglected diseases distributed worldwide with endemic areas in developed countries, where chronic infections are life threatening. Despite its impact, very little is known about the molecular biology of the parasite involved and its interplay with its hosts. Next generation sequencing technologies now provide unique opportunities to rapidly address these questions. Principal Findings: Here we present the first transcriptome of the third larval stage of S. stercoralis using 454 sequencing coupled with semi-automated bioinformatic analyses. 253,266 raw sequence reads were assembled into 11,250 contiguous sequences, most of which were novel. 8037…
La hospitalización domiciliaria ante los cambios demográficos y nuevos retos de salud
2002
Today, the most important demographic change taking place is the rapid aging of the population. While this phenomenon is having a growing and profound impact on all spheres of society, its greatest impact is in the health area, affecting all levels of health care and leading to the need for new resources and new structures. Out of that, in many countries have come different alternatives as well as in-patient, outpatient, and in-home programs that are geared toward improving health care and helping set priorities. One of these new initiatives is home hospitalization, or home health care. One objective of this study was to describe and analyze the characteristics of a population in Spain that…
An updated insight into the Sialotranscriptome of Triatoma infestans: developmental stage and geographic variations
2014
Background Triatoma infestans is the main vector of Chagas disease in South America. As in all hematophagous arthropods, its saliva contains a complex cocktail that assists blood feeding by preventing platelet aggregation and blood clotting and promoting vasodilation. These salivary components can be immunologically recognized by their vector's hosts and targeted with antibodies that might disrupt blood feeding. These antibodies can be used to detect vector exposure using immunoassays. Antibodies may also contribute to the fast evolution of the salivary cocktail. Methodology Salivary gland cDNA libraries from nymphal and adult T. infestans of breeding colonies originating from different loc…

The global distribution of lymphatic filariasis, 2000–18:a geospatial analysis
2020
Background Lymphatic filariasis is a neglected tropical disease that can cause permanent disability through disruption of the lymphatic system. This disease is caused by parasitic filarial worms that are transmitted by mosquitos. Mass drug administration (MDA) of antihelmintics is recommended by WHO to eliminate lymphatic filariasis as a public health problem. This study aims to produce the first geospatial estimates of the global prevalence of lymphatic filariasis infection over time, to quantify progress towards elimination, and to identify geographical variation in distribution of infection. Methods A global dataset of georeferenced surveyed locations was used to model annual 2000–18 lym…
