| presence of american cutaneous leishmaniasis vectors surrounding the city of medellín, colombia. | the presence of lutzomyia (helcocyrtomyia) hartmanni, as a vector of leishmania colombiensis and l. columbiana (verrucarum group), recently incriminated in the transmission of leishmaniasis, and l. pia (verrucarum group) are reported for the first time in a periurban area of medellín city. there is thus a risk of leishmaniasis transmission in this town. | 2002 | 12219126 |
| identification of endotrypanum species from a sloth, a squirrel and lutzomyia sandflies in ecuador by pcr amplification and sequencing of the mini-exon gene. | pcr amplification and nucleotide sequencing of the mini-exon gene revealed that four strains isolated from a sloth (choloepus hoffmanni), a squirrel (sciurus granatensis) and two sandflies (lutzomyia hartmanni) in ecuador were indistinguishable from endotrypanum monterogeii. another strain isolated from lu. hartmanni showed the high sequence similarity to e. schaudinni. since three of these strains have been previously identified as leishmania (viannia) equatorensis, the results demonstrate that ... | 2003 | 12808222 |
| first report of warileya rotundipennis (psychodidae: phlebotominae) naturally infected with leishmania (viannia) in a focus of cutaneous leishmaniasis in colombia. | the expansion of transmission of cutaneous leishmaniasis from sylvatic ecosystems into peri-urban and domestic settings has occurred as sand flies have adapted to anthropogenic environmental modifications. assessment of the intradomiciliary presence of sand flies in households of the settlement "la cabaña", in the department of risaralda, colombia, revealed an abundance of warileya rotundipennis. this unexpected observation motivated further analyses to evaluate the participation of this species ... | 2015 | 25917717 |
| taxonomy, diversity, temporal and geographical distribution of cutaneous leishmaniasis in colombia: a retrospective study. | leishmaniases are tropical zoonotic diseases, caused by kinetoplastid parasites from the genus leishmania. new world (nw) species are related to sylvatic cycles although urbanization processes have been reported in some south american countries such as colombia. currently, few studies show the relative distribution of leishmania species related to cutaneous leishmaniasis (cl) in south america due to the lack of accurate surveillance and public health systems. herein, we conducted a systematic es ... | 2016 | 27328969 |
| a study of a population of nyssomyia trapidoi (diptera: psychodidae) caught on the pacific coast of ecuador. | cutaneous leishmaniasis is endemic to the pacific coast of ecuador, and nyssomyia trapidoi is considered to be its main vector. dujardin et al. [1] recorded some differences in body pigmentation and isoenzymatic profiles in sympatric populations of ny. trapidoi from the pacific coast of ecuador and suggested the existence of two cryptic species. | 2012 | 22824472 |
| new records of phlebotomine sand flies (diptera: psychodidae) from ecuador. | the number of recorded phlebotomine sand fly species in ecuador has nearly doubled during the past 20 years as a result of surveys. in 2005, a sand fly survey of two localities, tiputini in the amazon rain forest and paraiso escondido in the pacific coastal lowland forest, resulted in the capture of 25 species. new records for ecuador consisted of five species from the amazonian region and one from paraiso escondido. the amazonian species were nyssomyia richardwardi (ready and fraiha), psathyrom ... | 0 | 22628901 |
| description of lutzomyia velezi, a new species of phlebotomine sand fly (diptera: psychodidae) from the department of antioquia, colombia. | the phlebotomine sand fly lutzomyia velezi sp.nov. was described and illustrated from male specimens collected by light trap in the reserva natural cañon del río claro in the central cordillera of the colombian andes. the new species belongs to the series sanguinaria of the subgenus helcocyrtomyia, which is represented in colombia by lutzomyia cirrita, lutzomyia hartmanni, lutzomyia sanguinaria, lutzomyia scorzai, lutzomyia sp. of pichindé and lutzomyia tortura. the new species can be differenti ... | 2010 | 20512248 |
| phlebotomine sand flies (diptera: psychodidae) of chiapas collected near the guatemala border, with additions to the fauna of mexico and a new subgenus name. | collections from four localities, two of the high plateau and two of the eastern mountains municipality of chiapas, near the border with guatemala, included 26 species with four new species records for mexico: lutzomyia (helcocyrtomyia) hartmanni (fairchild & hertig, 1957), dampfomyia (coromyia) disneyi (williams, 1987), psychodopygus bispinosus (fairchild & hertig, 1951), and psychodopygus corossoniensis (lepont & pajot, 1978). these records represent an updated total of 50 species in mexico, 4 ... | 2015 | 26250267 |
| dna barcoding for the identification of sand fly species (diptera, psychodidae, phlebotominae) in colombia. | sand flies include a group of insects that are of medical importance and that vary in geographic distribution, ecology, and pathogen transmission. approximately 163 species of sand flies have been reported in colombia. surveillance of the presence of sand fly species and the actualization of species distribution are important for predicting risks for and monitoring the expansion of diseases which sand flies can transmit. currently, the identification of phlebotomine sand flies is based on morpho ... | 2014 | 24454877 |
| description of lutzomyia (helcocyrtomyia) tolimensis, a new species of phlebotomine sandfly (diptera: psychodidae) from colombia. | a description is presented of lutzomyia tolimensis sp. nov., a new species of the subgenus helcocyrtomyia, series sanguinaria. it was collected in dwellings, peridomestic environment and in nearby forest patches located in the foothills of the andean central cordillera, where in 2004-2006 occurred the largest epidemic ever recorded of leishmaniasis in colombia. the male of this species is differentiated from other members of the series sanguinaria based on the following combination of characters ... | 0 | 23295748 |
| ecuador paraiso escondido virus, a new flavivirus isolated from new world sand flies in ecuador, is the first representative of a novel clade in the genus flavivirus. | a new flavivirus, ecuador paraiso escondido virus (epev), named after the village where it was discovered, was isolated from sand flies (psathyromyia abonnenci, formerly lutzomyia abonnenci) that are unique to the new world. this represents the first sand fly-borne flavivirus identified in the new world. epev exhibited a typical flavivirus genome organization. nevertheless, the maximum pairwise amino acid sequence identity with currently recognized flaviviruses was 52.8%. phylogenetic analysis o ... | 2015 | 26355096 |
