| ecological aspects and molecular detection of leishmania dna ross (kinetoplastida: trypanosomatidae) in phlebotomine sandflies (diptera: psychodidae) in terra firme and várzea environments in the middle solimões region, amazonas state, brazil. | phlebotomine sand flies (diptera: psychodidae) are insects of medical importance due to the role that some species play in the transmission of leishmaniasis. this work aimed to study some ecological aspects among sand flies fauna inhabiting two different environments: the várzea (lowland amazonian forest) and terra firme (upland amazonian forest), both located in tefé municipality, amazonas state, braziland to detect leishmania infection in those phlebotomine populations. | 2015 | 25889808 |
| molecular detection of leishmania in sand flies (diptera: psychodidae: phlebotominae) collected in the caititu indigenous reserve of the municipality of lábrea, state of amazonas, brazil. | phlebotominae sand flies are of medical importance because they are vectors of human pathogens, such as protozoa of the genus leishmania ross, etiological agent of american cutaneous leishmaniasis (acl). in lábrea, a municipality in the state of amazonas, brazil, acl is primarily associated with subsistence activities, such as collection and extraction of forest products, undertaken by both indigenous and nonindigenous people. data on acl in indigenous populations are scarce, such that there is ... | 2014 | 26309318 |
| further observations on lutzomyia ubiquitalis (psychodidae: phlebotominae), the sandfly vector of leishmania (viannia) lainsoni. | | 1992 | 1343653 |
| molecular identification of leishmania spp. in sand flies (diptera: psychodidae, phlebotominae) from ecuador. | the detection and identification of natural infections in sand flies by leishmania protozoan species in endemic areas is a key factor in assessing the risk of leishmaniasis and in designing prevention and control measures for this infectious disease. in this study, we analyzed the leishmania dna using nuclear ribosomal internal transcript spacer (its) sequences. parasite dna was extracted from naturally infected, blood-fed sand flies collected in nine localities considered leishmaniasis-endemic ... | 2017 | 28981860 |
| cutaneous leishmaniasis in the amazon region: natural infection of the sandfly lutzomyia ubiquitalis (psychodidae: phlebotominae) by leishmania (viannia) lainsoni in pará state, brazil. | | 1991 | 1842393 |
| sandfly fauna (diptera: psychodidae) from caves in the state of rondônia, brazil. | this study had the aim of ascertaining the sandfly fauna and possible presence of leishmania in these insects, collected in caves in the state of rondônia, brazil. collections were conducted in eight caves located in two different areas of this state. leishmania in the sandflies collected was detected using the polymerase chain reaction (pcr). this was the first study on sandflies from caves in rondônia and, among the total of 1,236 individuals collected, 24 species and 10 genera were identified ... | 2016 | 27007243 |
| natural leishmania (viannia) infections of phlebotomines (diptera: psychodidae) indicate classical and alternative transmission cycles of american cutaneous leishmaniasis in the guiana shield, brazil. | from 1996 to 1999 multi-trapping methods (center of diseases control, cdc) light traps, light-baited shannon traps, and aspiration on tree bases) were used to study the phlebotomine fauna of the "serra do navio" region of the brazilian state of amapá, which is part of the guiana shield. fifty-three species were identified among 8,685 captured individuals. the following species, associated with the transmission of american cutaneous leishmaniasis in amazonian brazil, were captured: nyssomyia umbr ... | 2017 | 28508745 |
| phlebotomine sand fly composition (diptera: psychodidae) and putative vectors of american cutaneous leishmaniasis in porto velho municipality, western amazon, brazil. | this study evaluated the species composition of sand flies and identified potential vectors of leishmania ross species in rural areas of porto velho, rondônia state, brazil. american cutaneous leishmaniasis (acl) is one of the gravest threats to public health in this state. sand flies were collected over the course of 2014 and 2015 using hp light traps. polymerase chain reaction was performed by targeting the leishmania mkdna region. in total, 2,344 sand flies were collected, from which 45 speci ... | 2017 | 28399264 |
| phlebotominae sand flies (diptera: psychodidae): potential vectors of american cutaneous leishmaniasis agents in the area associated with the santo antônio hydroelectric system in western amazonian brazil. | an entomological study was conducted as part of a vector-monitoring program in the area associated with the santo antônio hydroelectric system in state of rondônia, western amazonian brazil. | 2015 | 26108003 |
