“…However, certain differences in the distributions as well as recent epidemics in areas outside the geographic range of L. verrucarum indicate that other Lutzomyia species may serve as additional vectors (4,68,325). The role of human body lice (Pediculus humanus corporis) and their feces in the transmission of trench fever was well known already more than half a century before the discovery of B. quintana (66), but other vectors such as cat fleas (Ctenocephalides felis) have been occasionally reported as well (368).…”

SUMMARY Bartonella spp. are facultative intracellular pathogens that employ a unique stealth infection strategy comprising immune evasion and modulation, intimate interaction with nucleated cells, and intraerythrocytic persistence. Infections with Bartonella are ubiquitous among mammals, and many species can infect humans either as their natural host or incidentally as zoonotic pathogens. Upon inoculation into a naive host, the bartonellae first colonize a primary niche that is widely accepted to involve the manipulation of nucleated host cells, e.g., in the microvasculature. Consistently, in vitro research showed that Bartonella harbors an ample arsenal of virulence factors to modulate the response of such cells, gain entrance, and establish an intracellular niche. Subsequently, the bacteria are seeded into the bloodstream where they invade erythrocytes and give rise to a typically asymptomatic intraerythrocytic bacteremia. While this course of infection is characteristic for natural hosts, zoonotic infections or the infection of immunocompromised patients may alter the path of Bartonella and result in considerable morbidity. In this review we compile current knowledge on the molecular processes underlying both the infection strategy and pathogenesis of Bartonella and discuss their connection to the clinical presentation of human patients, which ranges from minor complaints to life-threatening disease.

“…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) . Lutzomyia peruensis, uno de los mosquitos implicados en la transmisión de la Leishmaniasis cutánea, fue el implicado en la epidemia ocurrida en el departamento del Cusco en 1998 (13,14) .…”

“…Éstas también participan en la transmisión de Bartonella bacilliformis (Strong et al, 1913), el agente etiológico de la bartonelosis humana (2,3). Taxonómicamente, el grupo verrucarum ha sido dividido en cuatro series de especies según el número y la distribución de las espinas sobre el estilo de la genitalia masculina: verrucarum, serrana, townsendi y pia (4).…”

Introducción. La serie pia del grupo verrucarum está integrada por siete especies de Lutzomyia, incluyendo a L. pia, L. limafalcaoae y L. emberai que están presentes en Colombia. Objetivo. Este artículo tiene como objetivo registrar el hallazgo de una morfoespecie antropofílica de la serie pia en el país. Materiales y métodos. Los flebotomíneos fueron recolectados con un aspirador bucal sobre cebo humano protegido dentro de un bosque secundario del municipio de Envigado, departamento de Antioquia. El muestreo entomológico se desarrolló entre las 18:00 y 22:00 horas, en junio y diciembre de 2004. Resultados. Los especímenes recolectados fueron identificados como L. tihuiliensis, que se distingue por la pigmentación basal de la pleura toráxica, la longitud del labro-epifaringe ³350 µm y la longitud del segundo palpómero ³170 µm. Adicionalmente, el taxón muestra un ducto común claramente más largo que los ductos individuales, con una relación de la longitud del ducto común/ducto individual ³2. Conclusión. Con el hallazgo de L. tihuiliensis se eleva a 21 el número de especies del grupo verrucarum registradas en Colombia. La presencia de cuatro especies de la serie pia en el país es de interés para el estudio de la génesis del taxón, considerando además que dos de éstas son endémicas del territorio nacional.Palabras clave: Psychodidae, Lutzomyia, leishmaniasis, Colombia. First finding of Lutzomyia tihuiliensis (Diptera: Psychodidae) in the Valle de Aburrá, ColombiaIntroduction. Three 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. Materials and Methods. Sand flies were collected with a mouth aspirator on protected human bait in a secondary forest in the municipality of Envigado, department of Antioquia. The entomological survey was performed from 18:00 to 22:00 hours in June and December, 2004. Results. Captured specimens were identified as L. tihuiliensis, which can be distinguished easily from other species of the pia series by its basally pigmented pleura, the length of the labro-epipharynx, ³350 µm, and the length of the second palpomere, ³170 µm. In addition to the previous characters, the sand flies collected exhibit a longer common sperm duct than the individual ducts with the ratio of the lengths of the common/individual ducts ³2. Conclusion. The finding of L. tihuiliensis raises to 21 the number of species of the Lutzomyia verrucarum group recorded to date in Colombia, including two endemic species of the pia series. From a biogeographical point of view, the presence of four species of the pia series in Colombia is of great interest for the study of the origin of the taxon.
