| possible determination of the vector and reservoir of leishmaniasis in the dominican republic. | two species of sand flies were collected by various methods from sites in the dominican republic. lutzomyia cayennensis hispaniolae was the more common of the two. it was found in wooded habitats from sea level to an elevation of 442 m. this species was observed feeding on lizards (anolis sp.) in the wild. in the laboratory, it fed only on lizards and only under lighted conditions. the other species, lu. christophei was only found in the vicinity of seven leishmaniasis case sites. it readily fed ... | 1992 | 1558267 |
| impact of habitat degradation on phlebotominae (diptera: psychodidae) of tropical dry forests in northern colombia. | we examined changes in the phlebotomine fauna resulting from human intervention in a tropical dry forest of northern colombia where visceral and cutaneous leishmaniases are endemic. a natural forest reserve (colosó) and a highly degraded area (san andrés de sotavento [sas]) were sampled monthly for 8 mo using shannon traps, sticky traps, and resting-site collections. overall abundances were higher in colosó (15,988) than in sas (2,324). and species richness of phlebotomines was greater in the fo ... | 2002 | 12061439 |
| [analysis of the primary and secondary structure of the mitochondrial serine transfer rna in seven species of lutzomyia]. | lutzomyia 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. | 2007 | 18320108 |
| "is leishmaniasis possible in puerto rico?". | in a survey encompassing eight different ecological regions, lutzomyia cayennensis puertoricensis was found in five, and l. c. viequesensis in one of 24 sites. the search centered on arboreal microhabitats. these subspecies were the two phlebotomids reported 40 years before by fairchild and co-workers. in the face of these findings the possibility of leishmaniasis being introduced from the dominican republic is discussed. it was concluded that conditions in puerto rico do not seem apt for the es ... | 2007 | 1876681 |
| current and future niche of north and central american sand flies (diptera: psychodidae) in climate change scenarios. | ecological niche models are useful tools to infer potential spatial and temporal distributions in vector species and to measure epidemiological risk for infectious diseases such as the leishmaniases. the ecological niche of 28 north and central american sand fly species, including those with epidemiological relevance, can be used to analyze the vector's ecology and its association with transmission risk, and plan integrated regional vector surveillance and control programs. in this study, we mod ... | 2013 | 24069478 |
| sandfly (diptera: psychodidae: phlebotominae) species diversity in an urban area of the municipality of tapachula, chiapas, mexico. | monitoring phlebotomine sandflies in urban areas is key for epidemiological studies in susceptible populations. this paper describes sandfly fauna that were present in an urban area of the municipality of tapachula, chiapas, mexico, and were captured with shannon and cdc light traps. during february and march of 2014, 1,442 sandflies were captured, specifically lutzomyia cruciata (coquillet) (98.8%), lutzomyia cayennensis cayennensis (floch and abonnenc) (0.8%), lutzomyia chiapanensis (dampf) (0 ... | 2015 | 25742275 |
| leishmania (leishmania) martiniquensis n. sp. (kinetoplastida: trypanosomatidae), description of the parasite responsible for cutaneous leishmaniasis in martinique island (french west indies). | the parasite responsible for autochthonous cutaneous leishmaniasis in martinique island (french west indies) was first isolated in 1995; its taxonomical position was established only in 2002, but it remained unnamed. in the present paper, the authors name this parasite leishmania (leishmania) martiniquensis desbois, pratlong & dedet n. sp. and describe the type strain of this taxon, including its biological characteristics, biochemical and molecular identification, and pathogenicity. this parasi ... | 2014 | 24626346 |
| evidence for anthropophily in five species of phlebotomine sand flies (diptera: psychodidae) from northern colombia, revealed by molecular identification of bloodmeals. | 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 extradomiciliar ... | 2016 | 26464046 |

| [natural infection of lutzomyia cayennensis cayennensis with trypanosomatid parasites (kinetoplastida: trypanosomatidae) in los montes de maria, colombia]. | the presence of sand flies naturally infected with trypanosomatid parasites was determined in los montes de maria, colombia, a region considered endemic for visceral and cutaneous leishmaniasis. phlebotomines were collected using cdc light-traps, and sticky traps soaked with castor oil placed in the peri and intradomestic habitats. six species of lutzomyia were morphologically identified among the 159 sand flies captured: lu. evansi, lu. cayennensis cayennensis, lu. trinidadensis, lu. atroclavat ... | 2013 | 23427416 |
| multivariate morphometric discrimination among three species of lutzomyia subgenus micropygomyia (diptera: psychodidae). | canonical discriminant analysis accurately separated males of lutzomyia yencanensis (n = 36) (ortiz), lutzomyia cayennensis cayennensis (n = 24) (floch and abonnenc) and lutzomyia micropyga (n = 28) (mangabeira). only seven (length of head, interocular distance, wing vein delta, genital filaments, coxite, paramere, and lateral lobe) of 20 possible morphometric measurements were required for differentiation, with a highly significant canonical correlation. the discriminant equations provided a si ... | 2003 | 14765649 |
