Publicación Acceso abierto Análisis de la estructura primaria y secundaria del ARN de transferencia mitocondrial para serina en siete especies de Lutzomyia.(Bogotá, Colombia: Revista Biomédica, 2007., 2019-10-21) Vivero, Rafael José; Contreras Gutiérrez, María Angélica; Bejarano, Eduar ElíasLutzomyia sand flies are involved in the transmission of the parasite Leishmania spp. in America. The taxonomy of these vectors is traditionally based on morphological features of the adult stage, particularly the paired structures of the head and genitalia. Although these characters are useful to distinguish most species of Lutzomyia, morphological identification may be complicated by the similarities within subgenera and species group. To evaluate the utility of mitochondrial serine transfer RNA tRNASer for taxonomic identification of Lutzomyia.Publicación Acceso abierto Cambios en el extremo carboxilo terminal de citocromo b como carácter taxonómico en Lutzomyia (Diptera: Psychodidae).(Bogotá, Colombia : Revista Colombiana de Entomología, 2009., 2019-10-16) Vivero, Rafael José; Contreras Gutiérrez, María Angélica; Bejarano, Eduar Elías; Sociedad Colombiana de Entomología .Morphological characters have been traditionally used for identification of sand flies of the genus Lutzomyia; however, their utility is limited in some species. In this work, we characterized the mitochondrial DNA region coding for the carboxyl-terminal domain of cytochrome b protein in seven species of Lutzomyia: L. trinidadensis, L. panamensis, L. cayennensis cayennensis, L. dubitans, L. gomezi, L. rangeliana and L. evansi. A total of 134 polymorphic sites were detected in the gene (40.98%) and 29 sites in the protein (26.6%). The very high level of polymorphism observed in cytochrome b, included replacement of amino acids, use of alternative stop codons, and differences in the size of the protein. The utility of the studied region in the identification of Lutzomyia species is discussed.Publicación Acceso abierto Detección de anticuerpos anti-leishmania (trypanosomatidae) en poblaciones caninas del departamento de Sucre, Colombia.(Bogotá, Colombia: Acta biológica Colombiana, 2016., 2019-10-01) Paternina Tuirán, Luis Enrique; Díaz Olmos, Yiris Arleth; Paternina Gómez, Margaret; Carrillo Bonilla, Lina María; Vélez, Iván Darío; Bejarano, Eduar ElíasThe aim of this survey was to determine prevalence of antibodies against Leishmania in dogs from Sucre, Colombia. We analyzed 122 dogs in rural areas from municipalities of Sampués, Ovejas and Sincelejo, by indirect immunofluorescence (IFA). Anti-Leishmania antibodies were detected in 69.6 % (95 % CI = 61.1 to 78.2) of the selected canine population. In the municipality of Sincelejo, Sampues and Ovejas, the seropositivities were 72 % (95 % CI = 61.1 to 82.8), 68.4 % (95 % CI = 52.3 to 84.5) and 55.5 % (95 % CI = 21.2 to 86.3) respectively. Seropositive animals were mainly young and adult dogs. The 17.6 % of seropositive dogs showed clinical signs compatible with canine leishmaniasis; onychogryphosis, alopecia and cachexia were the most common ones. The detected high frequency of canines with antibodies against Leishmania in the present study, highlights the hyperendemicity status of canine leishmaniasis in this area of the country and the high risk of disease outbreaks.Publicación Acceso abierto Detección de Leishmania spp. (Kinetoplastea: trypanosomatidae) en flebotomíneos (Diptera: psychodidae) asociados a la aparición del primer caso de leishmaniasis visceral en la vereda Toro, San Cayetano, Bolívar(Sincelejo : Universidad de Sucre 2017, 2018) Alemán Santos, Maira Alejandra; Eduar Elías Bejarano Martínez; Universidad de SucreEn la Costa Caribe Colombiana, la leishmaniasis visceral (LV) constituye un importante problema de Salud Pública, tradicionalmente los casos de esta enfermedad se restringían a municipios particulares del macrofoco de Los Montes de María, sin embargo, recientemente se han presentado nuevos brotes en áreas rurales que se consideraban libres de esta enfermedad. En tales escenarios, tanto los parásitos, como los reservorios y los insectos son desconocidos, lo que limita, el diseño y aplicación de medidas de control, en este contexto, el objetivo de este trabajo fue conocer las especies de flebotomíneos asociados a la aparición de un caso autóctono de LV que se presentó por primera vez en la vereda Toro, San Cayetano, Bolívar y detectar ADN de Leishmania spp. en estos insectos. El estudio se desarrolló en mayo del 2015, los flebotomíneos fueron capturados usando trampas de luz emitida por diodos (LED), las cuales fueron ubicadas y operadas entre las 18:00 y las 06:00 horas, éstas fueron ubicadas en ambientes peri y extradomésticos. Las hembras fueron determinadas taxonómicamente y las no alimentadas organizadas en grupos de hasta 20 individuos. La detección del ADN de los parásitos se realizó por PCR de la región conservada del minicírculo del kinetoplasto, del Espaciador Transcrito Interno (ITS 2) y para el gen mitocondrial Citocromo b (Cyt b), los productos obtenidos, fueron secuenciados y analizados en conjunto con cepas de referencia. En total se capturaron 2.178 flebotomíneos. La especie más abundante fue Lu. evansi (99.60%), seguida en orden descendente por Lu. dubitans (0.30%) y Lu. trinidadensis (0,1%). Con base en la región conservada del minicírculo, se encontró que Lu. evansi y Lu. dubitans presentaron una frecuencia mínima de infección con Leishmania del 2,71% (n: 29/1.070) y 25% (n: 1/4) respectivamente. En Lu. evansi se determinó que tres grupos presentaron infección con Le. infantum y con la PCR semi-anidada de la región del Espaciador Transcrito Interno (ITS 2), se encontró que Lu. evansi presentó una xiii frecuencia mínima de infección que corresponde a un 0,186% (n: 2/1.070), adicionalmente, se encontró que un grupo de esta especie presentó infección con Le. braziliensis. Se concluye que hembras de Lu. evansi y Lu. dubitans se infectan naturalmente con Leishmania spp. en la zona bajo estudio y que Lu. evansi se infecta con Le. infantum y Le. braziliensis, lo que sumado a sus antecedentes epidemiológicos como vector, su alta abundancia, amplia distribución, su capacidad de adaptación y sus hábitos alimenticios, sugieren que esta especie podría ser la responsable de la transmisión de estos parásitos en la zona y no se descarta la aparición de brotes cutáneos de la enfermedad.Publicación Acceso abierto Dosis diagnóstica y umbral de resistencia de Lutzomyia evansi (Diptera: Psychodidae), a dos insecticidas utilizados en salud pública en Colombia: deltametrina y lambdacihalotrina.(Buenos Aires, Argentina: Revista de la Sociedad Entomológica Argentina, 2009., 2019-10-15) Henriquez, Caterine; Pereira, Yaneth; Cochero, Suljey; Bejarano, Eduar Elías; Sociedad Entomológica Argentina.Insecticides are an important tool for controlling insect vectors of microorganism pathogens. The aim of this study was to determine the diagnostic dosages of deltamethrin and lambdacyhalothrin for the sand fly Lutzomyia evansi (Núñez-Tovar), a vector of Leishmania infantum in Colombia. Sand flies were collected in the Estación Experimental de Fauna Silvestre of Colosó, Sucre, a natural reserve that had not been previously treated with insecticides. Glass bottles were used for bioassays, following the simplified method (CDC) for detecting insecticide resistance. Wild females of L. evansi were exposed to different concentrations of insecticides during a test period of 80 minutes. The diagnostic dosages of deltamethrin and lambdacyhalothrin were established in 0,0007%, and 0,00035%, respectively, and the resistance threshold was calculated to be ten minutes for both insecticides, exposure period during which the mortality reached 100%. The time-mortality data suggest that lambdacyhalothrin have a lethal effect on L. evansi at a lower concentration than deltamethrin. The last insecticide was less toxic than lambdacyhalothrin.Publicación Acceso abierto Estimación del tiempo de desarrollo de Lutzomyia evansi bajo condiciones experimentales.(Barranquilla, Colombia: Salud Uninorte, 2012., 2019-10-08) Martínez Suárez, Claudia; Almanza Rodríguez, Carlos; Bejarano Martínez, Eduar ElíasThe objective of this research was to estimate the average development time of Lu. evansi, based on a laboratory colony composed of phlebotomineans from an urban area.Publicación Acceso abierto Estimación del tiempo límite de detección del gen citocromo b de humanos en hembras de Lutzomyia evansi.(Bogotá, Colombia : Revista biomédica, 2017., 2019-09-25) Vergara, José Gabriel; Verbel Vergara, Daniel; Bejarano, Eduar Elías; Montesino, Ana Milena; Pérez Doria, AlveiroMolecular biology techniques have allowed a better knowledge of sources of blood meals in vector insects. However, the usefulness of these techniques depends on both the quantity of ingested blood and the digestion process in the insect.Publicación Acceso abierto Estudio de los flebotomíneos (Diptera: Psychodidae) antropofílicos de la Serranía de La Macarena, Colombia.(Bogotá, Colombia: Revista Colombiana de Entomología, 2006., 2019-10-24) Bejarano, Eduar Elías; Duque, Patricia; Vélez, Iván Darío; Sociedad Colombiana de Entomología.A preliminary survey of the anthropophilic sand fly fauna of the Serranía de La Macarena, Colombia, is presented. Although leishmaniasis is endemic in the region, the vectors of the disease are yet unknown. Insects were collected in July and December using a mouth aspirator while they tried to bite humans between 18:00 and 22:00 hours. Ten species of Lutzomyia sand flies were identified from 89 female specimens collected: L. ayrozai, L. davisi, L. hirsuta hirsuta, L. carrerai carrerai, L. lichyi, L. amazonensis, L. sp. series squamiventris, L. yuilli, L. shawi, and L. sp. series townsendi. The subgenus Psychodopygus was most abundant, with six species that comprised 79.8% of all sand flies collected, followed by Nyssomyia with two species that constituted 16.9% of total captures. The verrucarum group and the subgenus Lutzomyia were each represented by one species. Finally, the epidemiological background of the species encountered are briefly reviewed.Publicación Acceso abierto Evidence for anthropophily in five species of phlebotomine sand flies (Diptera: Psychodidae) from northern Colombia, revealed by molecular identification of bloodmeals.(Reino Unido: Acta Tropica, 2015., 2019-11-06) Paternina, Luís E.; Verbel Vergara, Daniel; Romero Ricardo, Luís; Pérez Doria, Alveiro; Paternina Gómez, Margaret; Martínez, Lily; Bejarano, Eduar E.Identification of the bloodmeal sources of phlebotomine sand flies is fundamental to determining which species are anthropophilic and understanding the transmission of Leishmania parasites in natural epidemiological settings. The objective of this study was to identify sand fly bloodmeals in the mixed leishmaniasis focus of the department of Sucre, northern Colombia. In all 141 engorged female sand flies were analyzed, after being captured in intradomiciliary, peridomiciliary and extradomiciliary habitats with Shannon and CDC traps and by active searching in diurnal resting sites. Bloodmeals were identified by sequencing and analysis of a 358 bp fragment of the mitochondrial gene Cytochrome b (CYB) and a 330 bp fragment of the nuclear gene prepronociceptin (PNOC). Using both genes 105 vertebrate bloodmeals were identified, with an efficiency of 72% for CYB but only 7% for PNOC. Ten species of vertebrates were identified as providing bloodmeal sources for eight sand fly species: Homo sapiens (Lutzomyia evansi, Lu. panamensis, Lu. micropyga, Lu. shannoni and Lu. atroclavata), Equus caballus (Lu. evansi, Lu. panamensis and Lu. cayennensis cayennensis), Eq. asinus (Lu. evansi and Lu. panamensis), Bos taurus 4 (Lu. evansi, Lu. panamensis and Lu. c. cayennensis), Tamandua mexicana (Lu. shannoni and Lu. trinidadensis), Proechimys guyanensis (Lu. evansi, Lu. panamensis and Lu. c. cayennensis), Mabuya sp. (Lu. micropyga), Sus scrofa (Lu. evansi and Lu. gomezi) and Gallus gallus (Lu. evansi). Cattle, donkeys, humans and pigs were significantly more important than other animals (P = 0.0001) as hosts of Lu. evansi, this being the most abundant sand fly species. The five Lutzomyia species in which blood samples of human origin were detected included Lu. micropyga and Lu. atroclavata, constituting the first evidence of anthropophily in both species.Publicación Acceso abierto Flebotominos adultos e inmaduros (Diptera: Psychodidae): registros para el Caribe Colombiano.(Estado Aragua, Venezuela: Boletín de Malariología y Salud Ambiental, 2013., 2019-10-03) Vivero Gómez, Ortega Gómez, Edgar Rafael José; Aparicio Argumedo, Torres Gutiérrez, Carolina Yamileth; Muskus López, Bejarano Martínez, Eduar E. CarlosElaborating an inventory for Lutzomyia spp., without considering the immature forms of such insects, gives only a partial information about the species. Investigating immature phlebotomines represents a challenge and urgency especially in Leishmania spp. transmission areas. The objective of this study was to detect natural breeding sites, for an inventory of immature and adult phlebotomine community in the municipality of Colosó, Department of Sucre. Phlebotomine sandflies were collected between May and December of 2009, at the wild life experimental station in Colosó. Detection of immature stages was approached by direct visualization of soil and tree-substrate samples, incubation of substrate in laboratory conditions and use of emergence traps. Adult sampling was conducted by active diurnal search in resting places using bucal aspirators to collect the insects. Resting places were predominantly associated with tree trunks, such as holes in trunks and buttress roots. We collected 44 immatures of phlebotomine sandflies of which 32 belong to the following species: Lutzomyia migonei, Lu. dubitans, Lu. serrana, Lu. cayennensis cayennensis, Lu. micropyga, Lu. evansi, Lu. gorbitzi, Lu. ovallesi and Lu. shannoni. Also, up to 1231 adult individuals were collected and the most abundant species in descending order were Lu. evansi, Lu. micropyga and Lu. trinidadensis. The species Lu. migonei and Lu. gorbitzi are worth noticing given the fact that they represent new records for the Department of Sucre as well as the Caribbean Region in the country. It is necessary to include immature sampling as complementary information on phlebotomine surveys and in this way gather solid information to release proper species inventories with the remarks on potential vectors in leishmaniasis foci.Publicación Acceso abierto Identificación de Leishmania chagasi en canis familiaris en un foco de los Montes de María(2003) Rivero Rodriguez, Matilde ElenaLa leishmaniasis es una antropozoonosis que resulta del parasitismo de los macrófagos por un protozoario del género Lei"shmani"a; esta enfermedad es endémica en 88 países alrededor del mundo. La leishmaniasis visceral es la forma clínica más peligrosa, ya que cuando no es tratada tiempo puede ser mortal. Dentro del ciclo de vida del parásito, los reservorios se constituyen como un eslabón fundamental debido a que son la fuente de parásitos para el insecto vector; Canls fam1J/ar/s está considerado como el principal reservorio de Lei"shmani"a chagasi (agente causal de leishmaniasis visceral en América) y constituye el animal doméstico más importante en el área rural del Departamento de Sucre, el cual es considerado como una región de alto riesgo para la enfermedad. Por todo esto, se realizó el presente estudio en las veredas Loma de Piedra y El Retiro, pertenecientes al municipio de Sampues, en donde se evaluaron un total de 39 ejemplares caninos de raza mestiza (sintomáticos y asintomáticos). Se realizó un protocolo de PCR específico con dos pares de oligonucleótidos específicos para el género Lei"shmani"a (Lir/13Y y SSUF/SSUR) utilizando muestras de sangre periférica. A través de este protocolo se logró identificar ADN de Le/shmanla en seis de las muestras de perros obtenidas, correspondiendo a 12.2% de la población total estudiada. Se confirmó además a través de la utilización de los oligonucleótidos LU-5A/LC-3L que el parásito hallado corresponde a parásitos del complejo donovani, posiblemente Lei"shmani"a chagasiPublicación Acceso abierto Lutzomyia abonneci y Lutzomyia olmeca bicolor (Diptera: Psychodidae), nuevos registros para el departamento de Sucre, Colombia.(Bogotá, Colombia: Acta Biológica Colombiana , 2013., 2019-10-03) Romero Ricardo, Luis; Lastre Meza, Natalia; Pérez Doria, Alveiro; Bejarano Martínez, EduarAmong Colombia’s Caribbean coast departments, Sucre has the greatest species diversity of phlebotomine sand flies (genus Lutzomyia), including several associated with the epidemiological cycles of cutaneous and visceral leishmaniasis. Due to its public health importance, the phlebotomine fauna of Sucre must be monitored periodically. Sand flies were collected in the ecological reserve of the municipality of Colosó, Sucre, during the months of December 2009, 2010 and 2011. Three sampling methods were employed, i.e., daytime collections from diurnal resting sites with a battery-powered aspirator and nocturnal collections using two CDC light traps and a Shannon trap. With these methods 566 phlebotomines were collected belonging to 14 species: Lu.evansi, Lu. panamensis, Lu. micropyga, Lu.gomezi, Lu. cayennensis cayennensis, Lu. trinidadensis, Lu.venezuelensis, Lu. serrana, Lu. abonnenci, Lu. migonei, Lu. dubitans, Lu. olmeca bicolor, Lu. atroclavata and Lu. ovallesi. Shannon trap collections accounted for 48,2 % of all phlebotomines collected, those with CDC light traps 36,6 % and with battery-powered aspirator 15,2 %. Both Lu. abonnenci and Lu. o. bicolor, species with wide spread in Colombia, represent new species records for the department of Sucre.Publicación Acceso abierto Nuevos hallazgos de flebotomíneos (Diptera: Psychodidae) en la Sierra Nevada de Santa Marta, Colombia.(Bogotá, Colombia: Acta Biológica Colombiana , 2015., 2019-10-02) Bejarano, Uribe, Sandra Inés Eduar Elías; Pérez Doria, Agurrola, Jorge Alveiro; Dib, Porter, Charles H. Juan CarlosPhlebotomine sand flies, vectors of leishmaniasis, have not been well studied in the Sierra Nevada de Santa Marta, and likewise, are not well known in other regions of the Department of Magdalena, Colombia. To date only thirteen species of Lutzomyia have been recorded as occurring in the Department. The present note adds three species and includes an additional subgenus. Collections were made in the lower foothills of the Sierra Nevada de Santa Marta at elevations ranging from 117–130 m in the communities of Seywiaka, Las Tinajas and Calabazo. Eighty-four percent of the 885 phlebotomines sand flies collected were obtained from CDC light traps, 11 % from Shannon trap and 5 % from typical resting sites using an electric aspirator. The following nine species were identified from the collections: Lutzomyia gomezi, Lu. panamensis, Lu. trinidadensis, Lu. carpenteri, Lu. evansi, Lu. dysponeta, Lu. dubitans, Lu. shannoni, and Lu. micropyga. The most abundant species were Lu. gomezi and Lu. panamensis, which, respectively, accounted for 69 % and 14 % of the specimens. Of the nine species, Lu. carpenteri, Lu. dubitans and Lu. dysponeta represent new records for the Department of Magdalena. Also, a few female specimens were encountered of a species belonging to the Lu. osornoi series of the subgenus Helcocyrtomyia, which represents the first record of this subgenus in the Caribbean region of Colombia.Publicación Acceso abierto Nuevos registros de flebotomíneos (Diptera: Psychodidae) en el área de influencia del río Amoyá en Chaparral, Tolima.(Bogotá, Colombia: Revista Biomédica, 2012., 2019-10-04) Contreras, María Angélica; Vivero, Rafael José; Bejarano, Eduar Elías; Carrillo, Lina María; Carrillo, Lina María; Vélez, Ivan DaríoIn Colombia, the diversity of phlebotomine sand flies is high, with 162 recorded species, and which include vectors of Leishmania spp. The objective of this research is to identify the the sand fly species of medically importance in the area of influence from Amoyá River Hydroelectric Project, Colombia.Publicación Acceso abierto Nuevos registros de flebotomíneos (Diptera: Psychodidae), con el hallazgo de Lutzomyia longipalpis (Lutz & Neiva, 1912), en los alrededores de la Ciudad de Sincelejo, Colombia.(São Paulo, Brasil:Biota Neotropica, 2009., 2019-10-11) Vivero, Rafael José; Bejarano, Eduar Elías; Pérez Doria, Alveiro; Flórez, Fernando; Estrada, Luis Gregorio; Torres, Carolina; Muskus, CarlosThis is the first report of Lutzomyia longipalpis (Lutz & Neiva, 1912), L. shannoni (Dyar, 1929), L. micropyga (Mangabeira, 1942) and L. atroclavata (Knab, 1913) in the surroundings of an urban settlement in the Caribbean coast. Phlebotomine sandflies were collected by active search using suction devices and mouth aspirators in trees around the city of Sincelejo, the capital of the department of Sucre. Epidemiological importance derived from this finding is discussed due to the vectorial capacity of L. longipalpis, the natural vector of Leishmania infantum Nicolle, 1908 in America.Publicación Acceso abierto Predicción de la estructura secundaria del tRNASer (UCN) mitocondrial del flebotomíneo Lutzomyia hartmani (Diptera: Psychodidae).(Bogotá, Colombia: Acta Biológica Colombiana , 2011., 2019-10-09) Pérez Doria, Alveiro; Bejarano, Eduar E.Lutzomyia (Helcocyrtomyia) hartmanni is a sand fly that has been implicated in the transmission of Leishmania (Viannia) colombiensis, an etiologic agent of cutaneous leishmaniasis in Colombia. The objective of this work was to explore the potential usefulness of the mitochondrial serine transfer RNA (UCN) (tRNASer) in the taxonomic determination of L. hartmanni. Mitochondrial DNA was extracted, amplified and sequenced from entomological material collected in Envigado, Antioquia, Colombia. The tRNASer gene length was 68 nucleotide pairs, with an average adenine-thymine content of 80,9%. The studied tRNASer differs from other sand fly tRNASer known to date, on the basis of its primary and secondary structure. The observed number of intrachain base pairing was 7 in the acceptor arm, 3 in the dihydrouridine (DHU) arm, 5 in the anticodon arm, and 5 in the ribothymidine-pseudouridine-cytosine (T C) arm. The size of the DHU, anticodon, variable and T C loops was estimated to be 5, 7, 4, and 8 nucleotides, respectively. The notorious absence of non-Watson-Crick base pairs in the four arms of the tRNASer distinguishes that of L. hartmanni from others Lutzomyia spp.Publicación Acceso abierto Presence of Lutzomyia evansi, a vector of American visceral leishmaniasis, in an urban area of the Colombian Caribbean coast.(Londres, Reino Unido: Transactions of the Royal Society of Tropical Medicine and Hygiene , 2001., 2019-10-31) Bejarano, Eduar Elias; Uribe, Sandra; Rojas, Winston; Iván Darío, Vélez; Royal Society of Tropical Medicine and Hygiene.American visceral leishmaniasis (AVL) is a potentially fatal disease of neotropical countries, chiefly affecting children aged under 5 years, caused by ~ishmania (Leishmanial &a& Cunha & Chapas. which is indisiinguishablk from the ‘Old World’ paiasite Le. (Le.) injuntum Nicolle, of which it may be a synonym. AVL is transmitted to human or other mammalian hosts by the bites of the phlebotomine sandflies Lutzanzyia (Lutzomy&z) Zongt$alpis (Lutz & Neiva) or Lmmnyiu (Lutzomyia) evami (Nufiez-Tovar) (GRIMALDI et al., 1989; TRAVI et al., 1996). Although Lu. longipalpis is the most widespread and important vector of AVL, Lu. evarnsi has been confirmed as a primary vector in rural areas of the Caribbean coast of Colombia and in some areas of Venezuela (AGUIUR et aE., 1995; MONTOYA, 1996; FEIJCLWGELI et al., 19991. While conducting entomological studies in the urbad area of Sincelejo &y (9’ 18’ N. 75” 25’ WI in northern Colombia. we found adults of Lzk. eeransi ih houses and in peridbmiciliary environments. This is the first record of Lu. evansi from an urban area in Colombia.Publicación Acceso abierto Primer hallazgo de Lutzomyia tihuiliensis (Diptera: Psychodidae) en el valle de Aburrá, Colombia.(Bogotá, Colombia: Revista Biomédica, 2006., 2019-10-24) Bejarano, Eduar Elías; Sierra, Diana; Pérez Doria, Alveiro; Darío Vélez., IvánThree of the seven species that comprise the pia series of the Lutzomyia verrucarum group have been recorded in Colombia, including L. pia, L. limafalcaoae and L. emberai. Objective. The aim of this paper is to report the occurrence of an anthropophilic morphospecies of the pia series in the country.Publicación Acceso abierto Primer registro del flebotomíneo Warileya (Hertigia) hertigi en Antioquia, Colombia.(Bogotá, Colombia: Revista Biomédica, 2018., 2019-09-20) Bejarano, Eduar Elías; Uribe, Sandra; Vivero, Rafael JoséThe genus Warileya is one of the least-known taxa of sandflies, comprising only nine species, i.e., W. (Warileya) phlebotomanica, W. (Hertigia) hertigi, W. (W.) rotundipennis, W. (W.) nigrosacculus, W. (W.) yungasi, W. (W.) fourgassiensis, W. (W.) lumbrerasi, W. (W.) euniceae and W. (W.) leponti.Publicación Acceso abierto Variación temporal de especies de Lutzomyia (Diptera: Psychodidae) en el área urbana de Sincelejo (Colombia).(Barranquilla, Colombia: Salud Uninorte, 2012., 2019-10-08) Lambraño Cruz, Luz Fernanda; Bejarano Martínez, Eduar Elías; Manjarrez Pinzón, GustavoDesde hace más de diez años se registran casos autóctonos de leishmaniasis cutánea y visceral de ocurrencia esporádica en Sincelejo, principalmente en barrios periféricos de esta ciudad, situación que ha estado acompañada por el hallazgo de especies de Lutzomyia (6,14). Sin embargo, se desconoce la variación temporal de estas especies en el entorno urbano; información que podría ser útil para la toma de decisiones en la lucha antivectorial por parte de los entes de salud. Considerando que los flebotomíneos constituyen un riesgo para la población humana como transmisores de Leishmania spp, los objetivos de este trabajo fueron determinar la diversidad de especies del género Lutzomyia y su variación temporal en la zona urbana de Sincelejo.
