Distribucion geografica de Lutzomyia verrucarum (Townsend, 1913) (Diptera, Psychodidae, Phlebotominae), vector de la batonellosis humana en el Peru

Abstract

Lutzomyia verrucarum (Townsend, 1913) (Diptera: Psychodidae); the natural vector of Bartonella bacilliformis, agent of human bartonellosis (peruvian verruga or Carrion's disease), is a native species of Peru; its geographic distribution occurrs between latitudes 5 degrees and 13 degrees 25' South: in the Occidental and Interandean valleys of the Andean. The altitudinal distribution of Lu. verrucarum in the different valleys is as follows: Occidental between 1100 and 2980 m sea level and Interandean from 1200 to 3200 m sea level. Some discrepancies between the distribution of Carrion's disease and Lu. verrucarum suggest the existence of secondary vectors in certain areas where Lu. verrucarum is not present.

Isolation ofBartonella schoenbuchensisfromLipoptena cervi, a Blood-Sucking Arthropod Causing Deer Ked Dermatitis

“…Interestingly, among the known Bartonella spp., B. schoenbuchensis is most closely related to B. bacilliformis (9), an important human on May 12, 2018 by guest http://jcm.asm.org/ pathogen, which is the only other Bartonella sp. for which the vector is known to be a fly, the sandfly Lutzomyia verrucarum (5). B. schoenbuchensis strains display considerable heterogeneity, e.g., in their gltA sequences (9), a finding supported by the identification of five additional variants in this study (Table 1 and Fig.…”

Survey of Bartonella species infecting intradomicillary animals in the Huayllacallán Valley, Ancash, Peru, a region endemic for human bartonellosis.

“…[5][6][7] The sand fly Lutzomyia verrucarum has long been implicated as a vector of the disease in Peru 8 , and its distribution is very similar to that of bartonellosis. 9 Female Lutzomyia sand flies parasitize a range of warm-blooded animals as well as humans, 10 and thus could act as vectors should B. bacilliformis have a nonhuman host.…”

Experiencias en la prevención y control de la enfermedad de Carrión en el Perú

“…El vector implicado en la transmisión de Bartonella bacilliformis en el Perú, es la hembra de la Lutzomyia verrucarum (11) . Cáceres et al han señalado que en ciertas áreas verrucógenas no hay correlación entre la presencia de la L.verrucarum y la enfermedad de Carrión, lo que sugiere que en dichas áreas el vector podría ser otra especie de Lutzomyia, como Lutzomyia maranonensis y Lutzomyia robusta, las cuales se han adaptado a ambientes tropicales como Amazonas, Cajamarca y Ecuador (12) .…”
