| natural infection of lutzomyia neivai and lutzomyia sallesi (diptera: psychodidae) by leishmania infantum chagasi in brazil. | natural infections with leishmania were found in females of the phlebotomine sand flies lutzomyia neivai (pinto) (= nyssomyia neivai) and lutzomyia sallesi (galvão & coutinho) (= evandromyia sallesi) (diptera: psychodidae) from lassance, in the brazilian state of minas gerais. promastigotes were found in the pyloric region of the former species and in the abdominal midgut of the latter species. insects found to be infected by microscopic examination were macerated in saline solution and inoculat ... | 2009 | 19769049 |
| phlebotomine fauna, natural infection rate and feeding habits of lutzomyia cruzi in jaciara, state of mato grosso, brazil. | visceral leishmaniasis (vl) in brazil is transmitted by the phlebotomine lutzomyia longipalpis and in some midwestern regions by lutzomyia cruzi. studies of the phlebotomine fauna, feeding habits and natural infection rate by leishmania contribute to increased understanding of the epidemiological chain of leishmaniases and their vectorial capacity. collections were performed in jaciara, state of mato grosso from 2010-2013, during which time 2,011 phlebotomines (23 species) were captured (68.70% ... | 2014 | 25410993 |
| restricted outbreak of american tegumentary leishmaniasis with high microfocal transmission. | cutaneous leishmaniasis is endemic in salta, the northwestern province of argentina. we describe an outbreak involving five recreational hunters whose exposure was limited to several hours in a residual patch of primary forest. all patients presented with typical cutaneous lesions after a mean incubation period of 59 days (range 15-78), and one developed simultaneous mucosal involvement. polymerase chain reaction analysis of lesions confirmed leishmania (v.) braziliensis as the etiologic agent i ... | 2013 | 23339200 |
| sandflies (diptera: psychodidae) in an urban area of northeastern brazil. | the sandfly fauna is well studied globally. in brazil, sandfly fauna is very diverse in the northeast region, especially in states such as maranhão, ceará, and bahia. however, in the state of pernambuco, the distribution of these insects is still not well known. therefore, the objective of this study was to identify the different species that constitute the sandfly fauna in an urban area in the northeast region of brazil, where an outbreak of visceral leishmaniasis (vl) was recently reported. | 2017 | 28001216 |
| study of sand flies (diptera: psychodidae) in visceral and cutaneous leishmaniasis areas in the central-western state of minas gerais, brazil. | the transmission of leishmania involves several species of sand flies that are closely associated with various parasites and reservoirs, with differing transmission cycles in brazil. a study on the phlebotomine species composition has been conducted in the municipality of divinópolis, minas gerais, brazil, an endemic area for cutaneous leishmaniasis (cl), which has intense occurrence of visceral leishmaniasis (vl) cases. in order to study the sand flies populations and their seasonality, cdc lig ... | 2013 | 23178219 |
| [sand flies in timóteo, minas gerais, brazil] | sporadic cases of tegumentary leishmaniasis have occurred in timóteo, minas gerais state, basically among the rural population. in order to study the region's sand fly population, new jersey light traps were set in seven different neighborhoods. specimens were gathered from june through october 1994, december 1994, and january through march 1995, with a total of 3,240 hours per trap. a total of 4,396 sand flies were captured, distributed among two genera and twenty species: brumptomyia cunhai, b ... | 1997 | 10886917 |
| ecology of lutzomyia longipalpis in an area of visceral leishmaniasis transmission in north-eastern brazil. | visceral leishmaniasis is a major public health issue in south america, where the disease is rapidly spreading. changes in ecology and distribution of the principal vector, lutzomyia longipalpis are among the factors accounting for the increasing incidence of the disease in this region. however, information about the ecology of l. longipalpis is still incipient, which may directly impair the implementation of effective control programs. herein, the ecology of l. longipalpis was studied in a focu ... | 2013 | 23369878 |
