American visceral leishmaniasis (VL) is a vector-borne disease caused by Leishmania infantum (syn. chagasi) and transmitted by Lutzomyia longipalpis and Lutzomyia evansi phlebotomine sand flies. Dogs not only are the main host reservoirs of the parasite but also suffer the disease; therefore, canine VL (CVL) has assumed an important role in public health. In Colombia, human and CVL are restricted to two transmission foci: one in the north region (Caribbean coast) and other in the central south region (middle Magdalena River Valley). We present a CVL case involving a 2-year-old male dog with a history of lack of appetite, general weakness, and progressive loss of weight. A diagnosis of CVL was obtained using the direct parasitological examination in spleen and bone marrow samples stained with Giemsa and RT-qPCR. The infecting Leishmania species was identified as L. infantum by PCR-restriction fragment length polymorphism amplifying the Hsp70 gene from bone marrow and spleen samples and confirming by sequencing. The patient responded favorably to treatment with intramuscular meglumine antimoniate at a dose of 100 mg/kg daily for 8 weeks and oral allopurinol at a dose of 10 mg/kg every 12 hours until new indication. This is the first report of urban CVL in the city of Cali, Colombia, highlighting the need for surveillance and control programs in the municipalities of the department of Valle del Cauca, a region where VL has not been informed before. The findings also indicate the need to reinforce the surveillance programs in other rural and urban regions of the country where favorable eco-epidemiological conditions exist.
-This is the fi rst record of the presence of the medically important genus Lutzomyia França in the Department of Guainía, Colombia. Sand fl ies were collected biting humans in the surroundings of the urban area of the Municipality of Inírida. Three Lutzomyia species were taxonomically identifi ed Los fl ebotomíneos conforman un grupo de insectos de gran interés médico, debido, además de su dolorosa picadura que puede ocasionar reacciones alérgicas, a su papel fundamental en el ciclo epidemiológico de la leishmaniosis, enfermedad que en el último año incrementó su incidencia en Colombia en un 21,85% (Zambrano 2006). Se acepta comúnmente que la subfamilia Phlebotominae Rondani está representada en América por tres géneros: Lutzomyia França, Brumptomyia França & Parrot, y Warileya Hertig (Lewis et al. 1977). Al igual que los demás taxones de la subfamilia, las hembras de Brumptomyia exhiben hábitos hematófagos, apareciendo particularmente asociadas a madrigueras de armadillos, vertebrados que además de compartir su refugio, sirven de fuente de alimento (Ibáñez-Bernal 1999).Aunque el Departamento de Guainía, Colombia, es catalogado como una zona de mediano riesgo para la transmisión de leishmaniosis cutánea (Zambrano 2006), llama la atención que a la fecha no existían informes de la presencia de fl ebotomíneos en el área (Bejarano 2006). Durante una evaluación entomológica desarrollada en la región, se recolectaron ejemplares pertenecientes a tres especies fl ebotomíneas que intentaban picar al humano en el peridomicilio, los cuales constituyen el primer informe de la presencia de la subfamilia para este departamento. Adicionalmente, se registra por primera vez la ocurrencia de B. mesai Sherlock, en el litoral Caribe Colombiano.Guainía es considerado una reserva natural que presenta condiciones ecológicas de bosque húmedo tropical con
Few scientists have dedicated themselves to the study of Colombia’s cockroach diversity. As a result, there are large gaps in the taxonomic knowledge of Colombian cockroach fauna that make species identification difficult and little information is available on their geographic distribution. Therefore, a taxonomic study of the suborder Blattaria was undertaken by examining the literature and studying specimens available in the country’s main entomological collections. A list of genera with their respective distribution in the various biogeographic regions was obtained. Two thousand, one hundred and forty six adult specimens, distributed in 4 families, 15 subfamilies, and 47 genera were examined and identified. The material examined comes from localities belonging to 31 of the Colombian territory’s 32 departments. Distribution data were obtained for 50 genera in seven biogeographic provinces, mainly in the North Andean and Chocó-Magdalena provinces. Seven genera are presented as new records for Colombia: Buboblatta, Cahita, Cariblatta, Euthlastoblatta, Litopeltis, Macrophyllodromia and Nahublattella. The total number of cockroach genera in Colombia is raised to 61.
CARRILLO, L.M. Thirteen new records of Lutzomyia (Diptera: Psychodidae) for the department of Vichada, Colombian Orinoquia. Biota Neotrop. 10(2): http://www.biotaneotropica.org.br/v10n2/en/abstract?shortcommunication+bn01510022010. Abstract: Lutzomyia trinidadensissp., and L. (Evandromyia) sp., are recorded for the first time in the department of Vichada, Colombia. In addition, the presence of L. antunesi (Coutinho, 1939) and L. aragaoi (Costa Lima, 1932) in this department is confirmed. Sand flies were collected in the municipalities of Puerto Carreño, Cumaribo, and La Primavera, using CDC light traps, Shannon trap, and human bait, and by active search in resting places. The epidemiological importance of these sand fly species is discussed in relation with the cutaneous leishmaniasis. Resumen: Se informa el primer hallazgo de Lutzomyia trinidadensis (Newstead, 1922), L. bettinii Feliciangeli, Ramírez-Pérez & Ramírez, 1988, L. flaviscutellata (Mangabeira, 1942, L. yuilli Young & Porter, 1972, L. saulensis (Floch & Abonnenc, 1944, L. runoides (Fairchild & Hertig, 1953), L. ayrozai (Barretto & Coutinho, 1940), L. claustrei Abonnenc, Leger & Fauran, 1979, L. walkeri (Newstead, 1914), L. preclara Young & Arias, 1984 sp., L. (squamiventris) sp., y L. (Evandromyia) sp., en el departamento de Vichada, Colombia. También se confirma la presencia de L. antunesi (Coutinho, 1939) y L. aragaoi (Costa Lima, 1932) en este departamento. Los flebotomíneos fueron recolectados en los municipios de Puerto Carreño, Cumaribo, y La Primavera, con trampas de luz tipo CDC, trampa Shannon y atrayente humano, y mediante búsqueda activa en lugares de reposo. Se discute la importancia epidemiológica de estas especies de flebotomíneos en relación con la leishmaniosis cutánea.
The blaberid genus Schistopeltis Rehn is rediagnosed. Schistopeltis microschistos n. sp. is described and the genus is recorded for the first time from Colombia. A taxonomic key is given to distinguish the new taxon from the previously known species S. peculiaris (from Brazil) and S. lizeri (from Bolivia).
