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.201525889808
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 ...201426309318
sand fly fauna in chapare, bolivia: an endemic focus of leishmania (viannia) on the distribution and abundance of lutzomyia spp. (diptera: psychodidae) in bolivia is scarce. sand flies from an area of leishmania (viannia) braziliensis endemicity in the isiboro-secure national park in the department of cochabamba were captured and identified to species. in total, 945 sand flies (789 females and 156 males) belonging to 15 species were collected from the four collection points in two study villages in 2007. with 549 (58.1%) specimens, lutzomyia shawi was the most abund ...201223025199
phlebotomine sandfly fauna and natural leishmania infection rates in a rural area of cerrado (tropical savannah) in nova mutum, state of mato grosso in brazil.american cutaneous leishmaniasis (acl) has been reported in every municipality of the state of mato grosso, brazil, but the transmission epidemiology remains poorly understood. our study was developed in a rural area of the nova mutum municipality where four autochthonous cases of acl were reported in 2009. our aims were to describe the local phlebotomine sandfly fauna and to investigate the infection rates and infecting leishmania species in the captured sandflies.201323856858
comparative analysis of carbohydrate residues in the midgut of phlebotomines (diptera: psychodidae) from colony and field populations from amazon, brazil.leishmaniasis are worldwide diseases that occur in 98 countries including brazil, transmitted by the bite of female phlebotomines during blood feeding. in brazil it is known that some species of sand flies as lutzomyia longipalpis sensun latum (vector of leishmania infantum chagasi), lutzomyia flaviscutellata (vector of leishmania (leishmania) amazonensis) and lutzomyia antunesi [suspected vector of leishmania (viannia) lindenbergi] are incriminated of transmitting the parasite leishmania for th ...201627264642
the phlebotomine fauna (diptera: psychodidae) of guaraí, state of tocantins, with an emphasis on the putative vectors of american cutaneous leishmaniasis in rural settlement and periurban areas.phlebotomine sandflies were captured in rural settlement and periurban areas of the municipality of guaraí in the state of tocantins (to), an endemic area of american cutaneous leishmaniasis (acl). forty-three phlebotomine species were identified, nine of which have already been recognised as acl vectors. eleven species were recorded for the first time in to. nyssomyia whitmani was the most abundant species, followed by evandromyia bourrouli, nyssomyia antunesi and psychodopygus complexus. the s ...023903972
an outbreak of cutaneous leishmaniasis among soldiers in belém, pará state, brazil, caused by leishmania (viannia) lindenbergi n. sp. a new leishmanial parasite of man in the amazon region.eight cases of cutaneous leishmaniasis are recorded among soldiers of the brazilian forest infantry stationed in belém, state of pará, north of brazil. the infections, all acquired during manoeuvres in nearby degraded primary forest, are attributed to a new member of the subgenus viannia, leishmania (v.) lindenbergi n. sp. a further infection by this parasite was encountered in a woman, who lived very close to the same piece of forest. the new parasite has been characterised and differentiated f ...200211938695
aspects on the ecology of phlebotomine sand flies (diptera: psychodidae) from guaraí, state of tocantins, brazil, endemic area for american cutaneous brazil, american cutaneous leishmaniasis (acl) ecology involves a diversity of leishmania species transmitted by different sand fly species. workers involved in agricultural activities are those mainly affected by acl in some regions from tocantins state (to), brazil, where the disease can be established in new settlements. the objective of this study was to examine the seasonal and hourly frequency of sand fly species, focusing on the potential vectors of acl, in a settlement in guaraí (to), ...201728082651
