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 ...19957705493
natural leishmania infection of lutzomyia spp. in peru.natural infection of lutzomyia spp. with leishmania was studied with the aid of the polymerase chain reaction (pcr) in chaute, lima, perú, a locality endemic for andean cutaneous leishmaniasis (uta). the pcr, with primers specific for the l. braziliensis complex, was applied to sandfly pools. sandflies were sampled from april 1990 to may 1991 with cdc light traps in homes, and from near homes with a shannon trap using protected human bait. lu. verrucarum (4 pools) and lu. peruenis (2 pools) from ...19948036658
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 ...200717710315
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 ...201323416127
