| age structure, blood-feeding behavior, and leishmania chagasi infection in lutzomyia longipalpis (diptera: psychodidae) at an endemic focus of visceral leishmaniasis in colombia. | ecological studies on the sand fly lutzomyia longipalpis (lutz & neiva) were conducted during 1990-1992 in a small rural community in colombia where american visceral leishmaniasis (avl) is endemic. subsamples of sand flies collected weekly from pigpens, the interior of houses, and natural outdoor resting sites were dissected to determine physiological age and leishmania chagasi cunha & chagas infection rates. eleven female l. longipalpis had flagellates in their gut, 2 of which were successfull ... | 1995 | 7473616 |
| impact of habitat degradation on phlebotominae (diptera: psychodidae) of tropical dry forests in northern colombia. | we examined changes in the phlebotomine fauna resulting from human intervention in a tropical dry forest of northern colombia where visceral and cutaneous leishmaniases are endemic. a natural forest reserve (colosó) and a highly degraded area (san andrés de sotavento [sas]) were sampled monthly for 8 mo using shannon traps, sticky traps, and resting-site collections. overall abundances were higher in colosó (15,988) than in sas (2,324). and species richness of phlebotomines was greater in the fo ... | 2002 | 12061439 |
| [seroprevalence of canine visceral leishmaniasis in sector 8 of neiva and in four municipalities of huila, colombia]. | canine visceral leishmaniasis in endemic areas of colombia could be a public health risk factor given the zoonotic nature of the disease. ninety-six human cases of visceral leishmaniasis were reported in colombia in 2004, 5 of them in huila, where lutzomyia longipalpis has been incriminated as the main vector species. | 2006 | 17361848 |
