Chemical parameters and bacterial communities associated with larval habitats of Anopheles, Culex and Aedes mosquitoes (Diptera: Culicidae) in wester…

2016

AbstractAquatic larval habitat conditions influence the development, fitness and vectorial capacity of mosquitoes. In turn, human activities can influence these conditions and shape mosquito vector distribution, thus affecting pathogen circulation and transmission. We measured environmental factors (chemical and microbial) in mosquito larval habitats and evaluated their potential as predictors for the occurrence of different mosquito species in an arbovirus and malaria endemic region of western Kenya. We found significantly greater proportions ofAedes aegyptimosquito larvae in ammonium and phosphate rich habitats, suggesting that fertilizer usage could potentially increase aquatic habitat s…

Modulation of La Crosse virus infection in Aedes albopictus mosquitoes following larval exposure to coffee extracts

2013

This commentary highlights key points, basic ideas, and future outlooks presented by Eastep et al. (2012) in Frontiers in Physiology-Systems Biology. The authors have provided an interesting investigation about the successful use of an environmentally friendly product derived from plants as a larvicidal agent to control mosquito populations as well as a substance that could alter the vector competence of mosquitoes for arthropod-borne viruses (arboviruses). Specifically Eastep and collaborators used coffee extracts (with and without caffeine) to try to answer two hypothesis: first, coffee extracts could have good results as a mosquitocidal compounds applied in larval biotopes and second, vi…

Could malaria and dengue reappear in Spain?

2010

El aumento de la inmigración durante los últimos años en España ha facilitado la importación de numerosas enfermedades tropicales. Entre ellas, las de transmisión vectorial son algunas de las más complicadas de estudiar por la complejidad que conlleva la participación de diversos hospedadores en los ciclos de transmisión, así como por la necesidad de conocer todos los parámetros fisiológicos, bioecológicos y biogeográficos relacionados con el organismo vector para poder inferir las posibilidades reales de la emergencia o la reemergencia de las enfermedades pertinentes. En estas circunstancias, el presente trabajo aporta información acerca de enfermedades importadas de incuestionable interés…

Venezuela's humanitarian crisis, resurgence of vector-borne diseases, and implications for spillover in the region

2019

In the past 5–10 years, Venezuela has faced a severe economic crisis, precipitated by political instability and declining oil revenue. Public health provision has been affected particularly. In this Review, we assess the impact of Venezuela's health-care crisis on vector-borne diseases, and the spillover into neighbouring countries. Between 2000 and 2015, Venezuela witnessed a 359% increase in malaria cases, followed by a 71% increase in 2017 (411 586 cases) compared with 2016 (240 613). Neighbouring countries, such as Brazil, have reported an escalating trend of imported malaria cases from Venezuela, from 1538 in 2014 to 3129 in 2017. In Venezuela, active Chagas disease transmission has be…

Vertical transmission of naturally occurring Bunyamwera and insect-specific flavivirus infections in mosquitoes from islands and mainland shores of L…

2018

Background Many arboviruses transmitted by mosquitoes have been implicated as causative agents of both human and animal illnesses in East Africa. Although epidemics of arboviral emerging infectious diseases have risen in frequency in recent years, the extent to which mosquitoes maintain pathogens in circulation during inter-epidemic periods is still poorly understood. This study aimed to investigate whether arboviruses may be maintained by vertical transmission via immature life stages of different mosquito vector species. Methodology We collected immature mosquitoes (egg, larva, pupa) on the shores and islands of Lake Baringo and Lake Victoria in western Kenya and reared them to adults. Mo…

Autoecología de los culícidos (Diptera, Culicidae) en Castellón: diversidad, abundancias y enfermedades vectoriales

2023

La familia Culicidae es una de las familias de insectos que presentan mayor relevancia en la Sanidad Pública, ya que engloba algunas especies de dípteros capaces de actuar como vectores de enfermedades que afectan al ser humano, además de las molestas picaduras producidas debido a su alimentación hematofágica. Debido a esto, los mosquitos han sido uno de los principales objetivos en los programas de control con el fin de regular sus niveles poblacionales, evitando así la posible propagación de las enfermedades que son capaces de transmitir y reduciendo las molestias a poblaciones humanas cercanas. El mayor conocimiento de sus fenologías, abundancias, distribuciones, biologías y ecologías se…

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 …

Prevalence of ulcerative stomatitis in arbovirus infections in a Brazilian Northeast population

2020

Background Although there are no population-based studies that support an association, there are reports in the literature of mucocutaneous, vesiculobullous and ulcerated lesions in the oral mucosa in cases of arbovirus infection. The aim of this study is to analyze the prevalence of ulcerative stomatitis in individuals affected by arboviruses in a population of the municipality of Arcoverde, Pernambuco, Brazil. Material and Methods 1,003 people living in an area assigned to a Primary Health Care Unit were interviewed. A structured questionnaire was used for data collection, with questions about sociodemographic variables, residence conditions, general health information, as well as informa…
