| genetic diversity of the mitochondrial cytochrome b gene in lutzomyia spp., with special reference to lutzomyia peruensis, a main vector of leishmania (viannia) peruviana in the peruvian andes. | the genetic divergence caused by genetic drift and/or selection is suggested to affect the vectorial capacity and insecticide susceptibility of sand flies, as well as other arthropods. in the present study, cytochrome b (cyt b) gene sequences were determined in 13 species circulating in peru to establish a basis for analysis of the genetic structure, and the intraspecific genetic diversity was assessed in the lutzomyia (lu.) peruensis, a main vector species of leishmania (viannia) peruviana in p ... | 2013 | 23416127 |
| the population structure of lutzomyia verrucarum (diptera: psycodidae), a bartonella bacilliformis and leishmania peruviana vector in peru. | the population genetic structure of lutzomyia verrucarum (townsend), a sand fly disease vector of carrion's disease and cutaneous leishmaniasis in the peruvian andes, was characterized by sequencing 653 bp of cytochrome b and 1,125 bp of the nadh dehydrogenase subunit 4 genes of its mitochondrial genome. dna sequence variation within and between valleys was compared in a sample of 220 sand flies from three valleys (purisima, huaylas, and conchucos) and five departments (amazonas, cajamarca, piur ... | 2012 | 22308774 |
| isolation and molecular identification of leishmania (viannia) peruviana from naturally infected lutzomyia peruensis (diptera: psychodidae) in the peruvian andes. | leishmania (viannia) peruviana was isolated from 1/75 lutzomyia peruensis captured during may 2006 in an endemic cutaneous leishmaniasis region of the peruvian andes (chaute, huarochiri, lima, peru). sand fly gut with promastigotes was inoculated into a hamster and the remaining body was fixed in ethanol. l. (viannia) sp. was determined by polymerase chain reaction (pcr), and leishmania species through molecular genotyping by pcr-restriction fragment length polymorphism analyses targeting the ge ... | 2007 | 17710315 |
| cutaneous leishmaniasis in the peruvian andes: an epidemiological study of infection and immunity. | a prospective longitudinal survey of cutaneous leishmaniasis (leishmania peruviana) was carried out in peru on a study population of 4716 persons living in 38 villages (departments of lima, ancash and piura). demographic and clinical data were collected from all individuals, and a montenegro skin test (mst) was carried out on 72% (3418) of the study population. each household was revisited at 3-monthly intervals for up to 2 years to detect new leishmaniasis cases; 497 people received a second ms ... | 1995 | 7705493 |
