| leishmaniasis vector potential of lutzomyia spp. in colombian coffee plantations. | potential vectors of leishmania braziliensis vianna were assessed at four study sites in the mountainous valle del cauca, western colombia, from march to june 1989. in an active focus of transmission at 1450 m altitude, a coffee plantation at versalles, there were high densities of antropophilic phlebotomines: lutzomyia columbiana (ritorcelli & van ty) and lu.townsendi (ortiz), both in the verrucarum species group, and of lu.pia (fairchild & hertig). at a comparable altitude in a forest reserve ... | 1991 | 1768906 |
| evaluation of deltamethrin-impregnated bednets and curtains against phlebotomine sandflies in valle del cauca, colombia. | the effectiveness of bednets and curtains (nylon mesh 64 per cm2) impregnated with deltamethrin at 26 mg a.i./m2 in reducing the biting nuisance caused by three phlebotomine sandfly species: lutzomyia columbiana, lu.lichyi and the predominant lu.youngi (diptera: psychodidae), was evaluated at la guaira, a rural settlement in valle de cauca near cali, colombia. pairs of volunteers collected sandflies under impregnated bednets, in rooms protected by impregnated curtains or in unprotected rooms in ... | 1995 | 7548945 |
| association of lutzomyia columbiana (diptera: psychodidae) with a leishmaniasis focus in colombia due to species of the leishmania mexicana complex. | in colombia, leishmania mexicana has a scattered geographical distribution and no sand fly vectors have been associated with its transmission. during the present study, the anthropophilic sand fly lutzomyia columbiana was found to be the only species collected using diverse methods, in a small focus of le. mexicana in the municipality of samaniego, sw colombia. ecological data indicate that this sand fly species is present in both peri and intradomestic habitats, where it readily bites man. furt ... | 1999 | 10348975 |
| [new findings on the geographic distribution of the verrucarum group (diptera: psychodidae) in colombia]. | the incrimination of sand flies belonging to verrucarum species group in the leishmaniasis transmission underscores the need for a detailed information on the geographical distribution of these species. the current listing adds 34 new records that extend significantly the knowledge of the geographical distribution of the verrucarum group in colombia. the most important new records pertain to lutzomyia spinicrassa in the tropical dry forest of the atlantic coast, lutzomyia ovallesi in the orinoco ... | 2003 | 14582337 |
| isolation and characterization of bartonella bacilliformis from an expatriate ecuadorian. | carrion's disease is typically biphasic with acute febrile illness characterized by bacteremia and severe hemolytic anemia (oroya fever), followed by benign, chronic cutaneous lesions (verruga peruana). the causative agent, bartonella bacilliformis, is endemic in specific regions of peru and ecuador. we describe atypical infection in an expatriate patient who presented with acute splenomegaly and anemia 3 years after visiting ecuador. initial serology and pcr of the patient's blood and serum wer ... | 2008 | 18094131 |
| dna barcoding for the identification of sand fly species (diptera, psychodidae, phlebotominae) in colombia. | sand flies include a group of insects that are of medical importance and that vary in geographic distribution, ecology, and pathogen transmission. approximately 163 species of sand flies have been reported in colombia. surveillance of the presence of sand fly species and the actualization of species distribution are important for predicting risks for and monitoring the expansion of diseases which sand flies can transmit. currently, the identification of phlebotomine sand flies is based on morpho ... | 2014 | 24454877 |
| description of a new phlebotomine species (diptera: psychodidae, phlebotominae) and new records of sand flies from the state of acre, northern brazil. | groundbreaking studies of phlebotomine sand fly populations in assis brasil, state of acre, brazil, resulted in the collection of 13 new records of phlebotomine sand flies and one previously undescribed species. lutzomyia naiffi sp. nov. is described here. the new species is similar to lutzomyia columbiana (ristorcelli & van ty) in measurements and other morphological characters. | 2013 | 24699574 |
| [new records of phlebotomine sand flies (diptera: psychodidae) near the amoya river in chaparral, tolima]. | in colombia, the diversity of phlebotomine sand flies is high, with 162 recorded species, and which include vectors of leishmania spp. | 2012 | 23242300 |
| [identification of lutzomyia spp. (diptera: psychodidae) verrucarum group through electron microscopy of its eggs]. | the value of colombian phlebotomine eggs for species determination was studied with a scanning electron microscope. the species diversity and medical importance of the verrucarum group were the bases to select lutzomyia youngi, lutzomyia evansi, lutzomyia columbiana and lutzomyia longiflocosa. the egg surface was poligonal. lutzomyia youngi, and lutzomyia columbiana had pentagonal or hexagonal patterns; lutzomyia evansi elongated polygons and lutzomyia longiflocosa irregular polygonal sculpturin ... | 2006 | 11354968 |
