| host-parasite relationship of leishmania mexicana mexicana and lutzomyia abonnenci (diptera: psychodidae). | the life cycle of leishmania mexicana mexicana in the gut of the sand fly, lutzomyia abonnenci, was studied by light and electron microscopy. development was suprapylarian with initial establishment of parasites in the bloodmeal (posterior midgut), and anterior migration of parasites to the cardia/stomodeal valve region beginning at 2.5 days post-infection. flagellates were first observed in the esophagus at 3.5 days, in the posterior armature region of the pharynx at 5 days, and in the anterior ... | 1987 | 3826488 |
| leishmania differentiation in natural and unnatural sand fly hosts. | leishmania differentiation in the gut of phlebotomine sand flies was evaluated based on five light and electron microscopic studies of natural (leishmania panamensis/lutzomyia gomezi, leishmania chagasi/lutzomyia longipalpis) and unnatural (leishmania mexicana/lutzomyia abonnenci, leishmania panamensis/phlebotomus papatasi, leishmania major/lutzomyia longipalpis) life cycles. in the bloodmeal, transformation of amastigotes into stumpy promastigotes occurred before or during division. further div ... | 1993 | 8461893 |
| lutzomyia sand fly diversity and rates of infection by wolbachia and an exotic leishmania species on barro colorado island, panama. | sand flies (diptera, psychodidae, phlebotominae) in the genus lutzomyia are the predominant vectors of the protozoan disease leishmaniasis in the new world. within the watershed of the panama canal, the cutaneous form of leishmaniasis is a continuous health threat for residents, tourists and members of an international research community. here we report the results of screening a tropical forest assemblage of sand fly species for infection by both leishmania and a microbe that can potentially se ... | 2010 | 20231892 |
| ecuador paraiso escondido virus, a new flavivirus isolated from new world sand flies in ecuador, is the first representative of a novel clade in the genus flavivirus. | a new flavivirus, ecuador paraiso escondido virus (epev), named after the village where it was discovered, was isolated from sand flies (psathyromyia abonnenci, formerly lutzomyia abonnenci) that are unique to the new world. this represents the first sand fly-borne flavivirus identified in the new world. epev exhibited a typical flavivirus genome organization. nevertheless, the maximum pairwise amino acid sequence identity with currently recognized flaviviruses was 52.8%. phylogenetic analysis o ... | 2015 | 26355096 |
| diversity and distribution of sandflies (diptera: psychodidae: phlebotominae) in a military area in the state of amazonas, brazil. | this study reports the distribution, ecotopes and fauna diversity of sandflies captured in five training bases on a military reserve in manaus, state of amazonas (am). a total of 10,762 specimens were collected, which were distributed among 58 species, with the highest number recorded at base instruction 1 (bi1). a higher rate of species richness was found at the base instruction boina rajada and low levels of diversity associated with a high abundance index with the clear dominance of lutzomyia ... | 0 | 23903983 |
| lutzomyia adiketis sp. n. (diptera: phlebotomidae), a vector of paleoleishmania neotropicum sp. n. (kinetoplastida: trypanosomatidae) in dominican amber. | | 2008 | 18627624 |
| anthropophily of lutzomyia wellcomei (diptera: psychodidae) in an atlantic forest conservation unit in northeast brazil. | lutzomyia wellcomei (fraiha, shaw & lainson) (diptera: psychodidae) can act as an important vector of leishmania (viannia) braziliensis this study presents the results of collections carried out in a fragment of atlantic forest in a conservation unit of rio grande do norte state. collections occurred over 12 consecutive months using shannon and cdc traps. a total of 777 sand flies from eight species were collected: lutzomyia walkeri (newstead), lutzomyia evandroi (costa lima & antunes), lutzomyi ... | 2016 | 27330100 |
| description of psathyromyia (psathyromyia) baratai sp. n. (diptera: psychodidae: phlebotominae) from cantareira state park, são paulo, brazil. | the shannoni complex consists of a group of sand fly species included in the subgenus psathyromyia (psathyromyia) barretto, 1962, in which the females have banana-shaped spermathecae and the males have terminalia with digitiform parameres. the species included in the complex present morphological similarity, mainly among the females, and the males contribute most clearly to species differentiation. we describe a newspecies in the shannoni complex, psathyromyia baratai sp. n., on the basis of mor ... | 2016 | 26590192 |
