“…whitmani, besides being the most abundant overall (167/630), was most frequently found in the savannah (75.4%) as discovered in the State of Mato Grosso by Missawa e cols 5 . It is known that cutaneous leishmaniasis is a zoonosis of rural environments 35,36 similar to the settlements studied here.…”

“…They were found in three biomes (Amazon rainforest, savannah, and Pantanal) 4 . All the 141 cities from the State have recorded autochthonous cases of the integumental form of the disease in these three ecosystems 5 , and the human visceral form is distributed in 34 municipalities of the State of Mato Grosso, with higher prevalence in the south-central and southeast regions of the State 6 . Given the growing incidence and geographic spread of leishmaniasis, as well as the importance of the phlebotomine sandflies in the transmission of Leishmania species, this research aimed to analyze the phlebotomine sandfly fauna (Diptera: Psychodidae) in three rural settlements at the municipality of Cáceres, State of Mato Grosso, with a view to developing better control measures.…”

Introduction: Leishmaniasis is expanding across Brazil, including the State of Mato Grosso (MT). The aim of this study was to characterize the phlebotomine sandfly fauna at three rural settlements located in the municipality of Cáceres, MT, from August 2010 to July 2011. Methods: Sandfly captures were conducted at the forest border and in intra and peridomicile areas with automatic light traps, biweekly, from 5pm to 6am. Results: Of the 630 sandflies collected, 348 were female, and 282 were male. Captured specimens were distributed across 11 genera -Brumptomyia, Evandromyia, Expapillata, Lutzomyia, Martinsmyia, Micropygomyia, Nyssomyia, Pintomyia, Psathyromyia, Psychodopygus, species. Among these, six species had not been marked yet in MT (Brumptomyia avellari, Br. mangabeirai, Evandromyia aldafalcaoae, Micropygomyia echinatopharynx, Micropygomyia peresi, and Pa. campograndensis). Nyssomyia whitmani was the most abundant species across ecotopes at all settlements. Interestingly, Lutzomyia longipalpis and Lutzomyia cruzi were found in sympatry. Conclusions: The disorganized occupation of the environment that is happening at the rural settlements of Mata Comprida, Laranjeira I and II could provide opportunities for the domiciliation of wild populations of phlebotomine, including vectors of leishmaniasis. Therefore, more studies are needed to understand the epidemiology of the disease in these areas and its impact on the human population. Keywords: Mato Grosso. Phlebotomine fauna. Nyssomyia whitmani. Rural settlement. RESUMO Introdução:As leishmanioses encontram-se em expansão no Brasil, inclusive no Estado de Mato Grosso (MT). A presente pesquisa teve como objetivo estudar a fauna flebotomínica em três assentamentos rurais localizados no município de Cáceres, MT, entre agosto de 2010 e julho de 2011. Métodos: As coletas foram realizadas na margem da mata, no intra e peridomicílio com armadilhas automáticas luminosas, quinzenalmente, das 17h às 6h. Resultados: Foram coletados 630 exemplares, sendo 348 fêmeas e 282 machos. Os espécimes foram distribuídos em 11 gêneros: Brumptomyia, Evandromyia, Expapillata, Lutzomyia, Martinsmyia, Micropygomyia, Nyssomyia, Pintomyia, Psathyromyia, Psychodopygus e Sciopemyia e 28 espécies, sendo que dentre estas, seis não haviam sido assinaladas em MT (Brumptomyia avellari, Br. mangabeirai, Evandromyia aldafalcaoae, Micropygomyia echinatopharynx, Micropygomyia peresi e Pa. campograndensis). Ressalta-se o encontro de Nyssomyia whitmani, espécie mais abundante nos diferentes ecótopos em todos os assentamentos. Destaca-se também a presença das espécies Lutzomyia longipalpis e Lutzomyia cruzi em simpatria. Conclusões: A ocupação desordenada do ambiente, como vem ocorrendo nos assentamentos Mata Comprida, Laranjeira I e II, pode proporcionar a domiciliação de populações selváticas de flebotomíneos, dentre estes os vetores das leishmanioses, tornando-se necessários maiores estudos para entender a dinâmica de transmissão dessas morbidades nestes locais.

Introduction: 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 sandfl y fauna and to investigate the infection rates and infecting Leishmania species in the captured sandfl ies. Methods: Entomological captures were performed bimonthly at 10 fi xed sites close to the edge of a forested area between June 2011 and April 2012. Results: A total of 3,743 phlebotomine sandfl ies belonging to 31 distinct species were captured. Approximately 75% of the specimens were females. The most abundant species (45.4%) was Lutzomyia antunesi, which was consistently captured at every site. Species that are epidemiologically important for ACL, such as L. fl aviscutellata, L. whitmani and L. umbratilis, were also captured. L. antunesi and L. ubiquitalis were naturally infected by Leishmania braziliensis or Le. guyanensis, with minimum infection rates of 0.88% and 6.67%, respectively. Surprisingly, L. antunesi was infected by Le. infantum (synonym chagasi). Conclusions: The natural infection of L. antunesi and L. ubiquitalis by Leishmania sp. suggests that these species might play a role in the zoonotic cycle of ACL in Nova Mutum. The presence of Le. infantum in L. antunesi suggests that there may be a risk of an outbreak of visceral leishmaniasis (VL) in Nova Mutum.

“…It was identified in a two-year-old child who lived in the Administrative Region (AR) of Guara and who had never left the Federal District (FD) (3). In the early 1990s, the urban presence of Lutzomyia (Nyssomyia) whitmani (phlebotomine sand flies) was reported in the FD (4,5). Four years later, four cases of ACL were published, and the hypothesis of peridomestic infection was raised.…”

Abstract:The first autochthonous case of American cutaneous leishmaniasis was reported in the Federal District in 1980, and the species involved in this type of leishmaniasis was unknown. This study aimed to identify the species that causes the disease in the Federal District and to investigate its clinical and epidemiological aspects. Between 2000 and 2007, 71 autochthonous cases of leishmaniasis were reported in the Federal District. Leishmania species were identified by means of direct immunofluorescence reactions using monoclonal antibodies and restriction fragment length polymorphism. The species of 40 (56.33%) out of 71 samples were identified. Thirty-six (90%) were identified as Leishmania (Viannia) braziliensis and four (10%) were identified as Leishmania (Leishmania) amazonensis. In this area, the disease had clinical and epidemiological characteristics similar to those found in other Brazilian regions.
