| evaluation of a pcr-rflp-its2 assay for discrimination of anopheles species in northern and western colombia. | anopheles mosquitoes are routinely identified using morphological characters of the female that often lead to misidentification due to interspecies similarity and intraspecies variability. the aim of this work was to evaluate the applicability of a previously developed pcr-rflp-its2 assay for accurate discrimination of anophelines in twelve localities spanning three colombian malaria epidemiological regions: atlantic coast, pacific coast, and uraba-bajo cauca-alto sinu region. the evaluation of ... | 2011 | 21345325 |
| larval habitat characteristics of the main malaria vectors in the most endemic regions of colombia: potential implications for larval control. | malaria incidence has recently decreased globally and, as malaria elimination is envisioned as a possibility by the health authorities, guidance is needed to strengthen malaria control strategies. larval source treatment, which could complement routine vector control strategies, requires knowledge regarding the anopheles larval habitats. | 2015 | 26620401 |
| spatial association between malaria vector species richness and malaria in colombia. | malaria transmission in colombia is highly variable in space and time. using a species distribution model, we mapped potential distribution of five vector species including anopheles albimanus, anopheles calderoni, anopheles darlingi, anopheles neivai, and anopheles nuneztovari in five departments of colombia where malaria transmission remains problematic. we overlaid the range maps of the five species to reveal areas of sympatry and related per-pixel species richness to mean annual parasite ind ... | 2016 | 26970373 |
| malaria in gold-mining areas in colombia. | gold-mining may play an important role in the maintenance of malaria worldwide. gold-mining, mostly illegal, has significantly expanded in colombia during the last decade in areas with limited health care and disease prevention. we report a descriptive study that was carried out to determine the malaria prevalence in gold-mining areas of colombia, using data from the public health surveillance system (national health institute) during the period 2010-2013. gold-mining was more prevalent in the d ... | 0 | 26814645 |
| human biting activity, spatial-temporal distribution and malaria vector role of anopheles calderoni in the southwest of colombia. | anopheles calderoni was first recognized in colombia in 2010 as this species had been misidentified as anopheles punctimacula due to morphological similarities. an. calderoni is considered a malaria vector in peru and has been found naturally infected with plasmodium falciparum in colombia. however, its biting behaviour, population dynamics and epidemiological importance have not been well described for colombia. | 2015 | 26104785 |
| spatial distributions of anopheles species in relation to malaria incidence at 70 localities in the highly endemic northwest and south pacific coast regions of colombia. | a proper identification of malaria vectors is essential for any attempt to control this disease. between 40 and 47 anopheles species have been recorded in colombia, and eight species complexes have been identified in the last decade. an update of anopheles species distribution and its relationship with malaria is required, particularly for newly identified members of species complexes. | 2016 | 27515166 |
| entomological monitoring and evaluation: diverse transmission settings of icemr projects will require local and regional malaria elimination strategies. | the unprecedented global efforts for malaria elimination in the past decade have resulted in altered vectorial systems, vector behaviors, and bionomics. these changes combined with increasingly evident heterogeneities in malaria transmission require innovative vector control strategies in addition to the established practices of long-lasting insecticidal nets and indoor residual spraying. integrated vector management will require focal and tailored vector control to achieve malaria elimination. ... | 2015 | 26259942 |
| malaria vectors in ecologically heterogeneous localities of the colombian pacific region. | the colombian pacific region is second nationally in number of malaria cases reported. this zone presents great ecological heterogeneity and anopheles species diversity. however, little is known about the current spatial and temporal distribution of vector species. this study, conducted in three ecologically different localities of the pacific region, aimed to evaluate the composition and distribution of anopheles species and characterize transmission intensity. a total of 4,016 anopheles mosqui ... | 2014 | 25090233 |
| molecular taxonomy provides new insights into anopheles species of the neotropical arribalzagia series. | phylogenetic analysis of partial mitochondrial cytochrome oxidase c subunit i (coi) and nuclear internal transcribed spacer 2 (its2) sequences were used to evaluate initial identification and to investigate phylogenetic relationships of seven anopheles morphospecies of the arribalzagia series from colombia. phylogenetic trees recovered highly supported clades for an. punctimaculas.s., an. calderoni, an. malefactor s.l., an. neomaculipalpus, an. apicimacula s.l., an. mattogrossensis and an. perya ... | 2015 | 25774795 |
| confirmation of anopheles (anopheles) calderoni wilkerson, 1991 (diptera: culicidae) in colombia and ecuador through molecular and morphological correlation with topotypic material. | the morphologically similar taxa anopheles calderoni, anopheles punctimacula, anopheles malefactor and anopheles guarao are commonly misidentified. isofamilies collected in valle de cauca, colombia, showed morphological characters most similar to an. calderoni, a species which has never previously been reported in colombia. although discontinuity of the postsubcostal pale spots on the costa (c) and first radial (r1) wing veins is purportedly diagnostic for an. calderoni, the degree of overlap of ... | 2010 | 21225197 |
