SUMMARYThe Aquidauana municipality is considered an endemic area of leishmaniasis and an important tourist site in Mato Grosso do Sul State. The aim of this study was to investigate the sand fly fauna in the city of Aquidauana. Captures were carried out twice a month, from April 2012 to March 2014 with automatic light traps and active aspiration, in the peridomicile and domicile of six residences. A total of 9,338 specimens were collected, 3,179 and 6,159 using light traps and active aspiration, respectively. The fauna consisted of: Brumptomyia brumpti, Evandromyia aldafalcaoae, Ev. evandroi, Ev. lenti, Ev. orcyi, Ev. sallesi, Ev. termitophila, Ev. walkeri, Lutzomyia longipalpis and Psathyromyia bigeniculata. The most abundant species captured was Lutzomyia longipalpis, present in all the ecotopes, predominantly in peridomicile areas, and mainly males. Leishmania DNA was not detected in the insects. It was observed the abundance of the sand fly fauna in the region, as well as the high frequency of Lu. longipalpis, the main vector of L. infantum. The results of this study show the need to increase the monitoring and more effective control measures. It is noteworthy that the studied region presents several activities related to tourism and recreation, increasing the risk of transmission of leishmaniasis to this particular human population.

“…Missawa and Maciel (2007) attributed the variety found in the state of Mato Grosso to the diversity of biomes such as savannah (cerrado), Pantanal, Amazon transition forest and Amazon forest, and this was also observed by Alves et al (2012), in a study conducted in rural settlements in the municipality of Cáceres.…”

Visceral leishmaniasis (VL) is caused by Leishmania (L.) infantum chagasi in the Americas. In Brazil, it is transmitted by sandflies of the species Lutzomyia longipalpis and L. cruzi, and dogs are the main domestic reservoirs. The aim of this study was to analyze data relating to VL transmission in Jaciara, state of Mato Grosso, and discuss vector distribution, domestic reservoirs, and human cases that occurred between 2003 and 2012. The data for analysis were obtained from the Notifiable Diseases Information System (human), the State Health Department's Environmental Monitoring Agency (canine data) and the State Health Department's Entomology Laboratory (sandfly data). Over this period, Jaciara had 19 autochthonous human cases (12 males and seven females), with one death 2,273. Out of the 7,545 dogs tested by enzyme immunoassay and indirect immunofluorescence were positive. The sandflies collected comprised 5,015 individuals belonging to 24 species, with a predominance of L. whitmani followed by L. cruzi. The results showed that the parasite has frequent circulation and that the vector L. cruzi is widely distributed over all months, thus suggesting that transmission may occur at any time of the year.Keywords: Visceral leishmaniasis (VL), Lutzomyia cruzi, Lutzomyia whitmani, Canine Reservoir. ResumoA leishmaniose visceral (LV), causada nas Américas pelo protozoário Leishmania (L.) infantum chagasi, transmitida no Brasil por flebotomíneos das espécies Lutzomyia longipalpis e L. cruzi, tem os cães como principais reservatórios domésticos. O objetivo deste trabalho foi analisar os dados relacionados à transmissão da LV, em Jaciara (MT), e discutir a respeito da distribuição do vetor, reservatório doméstico e os casos humanos ocorridos no período de 2003 a 2012. Os dados para análise foram obtidos do Sistema de Informações de Agravos de Notificação (humanos), da Vigilância Ambiental da Secretaria Estadual de Saúde (caninos) e do Laboratório de Entomologia da Secretaria Estadual de Saúde (flebotomíneos). Jaciara apresentou 19 casos autóctones, 12 do sexo masculino e sete do sexo feminino, com um óbito. Dos 7.545 cães testados por imunoensaio enzimático e reação de imunofluorescência indireta, 2.273 foram reagentes. Os flebotomíneos coletados totalizaram 5.015 indivíduos pertencentes a 24 espécies com predomínio de L. whitmani seguido por L. cruzi. Os resultados demonstraram circulação frequente do parasito e a ampla distribuição do vetor L. cruzi com frequência em todos os meses, sugerindo que a transmissão possa ocorrer em qualquer época do ano.Palavras-chave: Leishmaniose Visceral (LV), Lutzomyia cruzi, Lutzomyia whitmani, Reservatório Canino.

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.
