“…Uma espécie que chama bastante atenção, apesar de pouco representada aqui é L. yuilli, com sua reconhecida importân-cia médica na transmissão de Leishmania para humanos na Colômbia, tendo sido encontrada naturalmente infectada com L. (V.) panamensis (Santamaría et al, 2006), indicando participação ativa na transmissão dessa espécie, que causa mais de 50% dos casos de LTA no país (Vergara et al, 2008). Em 1998, Ferro e Morales também encontraram essa espécie infectada com flagelados não identificados na cidade de Letícia -Colôm-bia, fronteira com Tabatinga-AM, Brasil.…”

ResumoOs flebotomíneos transmitem doenças a humanos e animais, como as arboviroses e bartonelose, além das leishmanioses. O objetivo desta pesquisa foi identificar possíveis espécies de flebotomíneos vetores da doença nessa região no município de Tabatinga. Flebotomíneos foram capturados com armadilhas luminosas e em coletas manuais por aspiração em bases das árvores. Nos meses de agosto dos anos 2010 e 2011, foram capturados 4.542 flebotomíneos (♂: 71,9% e ♀: 28,1%) vetores ou suspeitos de transmitirem tripanosomatídeos, pertencentes a 13 espécies. A espécie mais abundante foi Lutzomyia umbratilis com 78,7%. Um total de 576 (74,0%) flebotomíneos do gênero Lutzomyia foram dissecados, sendo observada infecção natural por tripanosomatídeos em 44 fêmeas. Observou-se no trato digestório dos flebotomíneos a presença de sangue em decomposição em 86,3%; sendo que no que se refere aos ovários, 59,0% mostravam-se em desenvolvimento. A análise isoenzimática de dez isolados, demonstrou perfis similares a Leishmania colombiensis e Endotrypanum sp., no entanto, o perfil do locus Malato Desidrogenase (MDH) demonstrou maior similaridade para o gênero Endotrypanum. Esta é a primeira investigação da fauna entomologia e tentativa de isolamento de tripanosomatídeos no município de Tabatinga, área de tríplice fronteira com o Brasil.Palavras-chave: Amazonas, Endotrypanum, flebotomíneos, Lutzomyia. Vectors of Trypanosomatids (Kinetoplastida: Trypanosomatidae) in Tabatinga,Amazonas, Brazil AbstractThe sand flies transmit diseases to humans and animals, such as arboviruses and bartonellosis, besides the leishmaniasis. The objective of this research was identified potential vectors of this disease in the municipality of Tabatinga. Sand flies were captured with miniature light trap and manual collection by aspiration at the bases of trees. In the months of august 2010 and 2011, were captured 4,542 sand flies (♂: 71.9% and ♀: 28.1%) vectors or suspected of trypanosomatids transmission, belonging to 13 species. The most abundant species was Lutzomyia umbratilis with 78,7%. A total of 576 (74.0%) sand flies of the genus Lutzomyia were dissected and natural infection by trypanosomatids was observed in 44 females. Blood in decomposition was detected at the digestive tract in 86,3% insects; being 59.0% of the ovaries in developing. The isoenzymatic analysis of ten isolates showed similar profiles to Leishmania colombiensis and Endotrypanum sp., however, the profile of the locus Malate Dehydrogenase (MDH) showed major similarity to the genus Endotrypanum. This is the first investigation of the fauna entomology and attempt of trypanosomatids isolation in the municipality of Tabatinga, area of triple border with Brazil.

“…The most abundant species in the study area was Ny. yuilli yuilli ; it was reported for the first time in Caldas in 2008 (Vergara et al 2008). This species has been found in forests, as well as in the peri and intradomicile (Barreto et al 2000, Cortés 2006, Sandoval et al 2006, Santamaría et al 2006).…”

“…However, several studies on endemic foci of leishmaniasis have found this species in places where the environments are quite disturbed (Santamaría et al 2006). In Colombia, its distribution has been attributed to the Andean region (Young and Duncan 1994, Vergara et al 2008), but it has also been recorded in the Amazon region; however, the revalidation of the Ny. fraihai (Martins, Falcão & Silva, 1979) (closely related species) reinforces the necessity of evaluating the identification of this taxon in that region (Godoy and Galati 2016).…”

The community structure of sand flies indicates the level of adaptation of vector species in a region, and in the context of vector management and control, this information allows for identifying the potential risks of pathogen transmission. This study aimed to analyze sand fly diversity and spatial-temporal distribution in an endemic area of cutaneous leishmaniasis. The study was carried out in the Carrizales hamlet (Caldas), between September 2019 and October 2021. The monthly distribution of sand fly species was evaluated through collections with CDC traps. Shannon and evenness indices were calculated and used to compare species frequencies at each house. The association between climatic variables and the frequency of sand flies was evaluated using Spearman’s correlation. A total of 6,265 females and 1,958 males belonging to 23 species were found. Low diversity and evenness were observed, with the dominance of Nyssomyia yuilli yuilli (Young & Porter). Ecological and diversity indices did not reveal differences between the houses. The sand fly community was composed of 3 dominant species, Ny. yuilli yuilli, Psychodopygus ayrozai (Barretto & Coutinho), and Ps. panamensis (Shannon), representing 75.8% of the total catches. No statistical association was found between the absolute frequency of sand flies, rainfall, and temperature. The results show one dominant species, this fact has epidemiological relevance since density influences parasite-vector contact. The high densities of sand flies recorded in peri- and intradomiciliary areas highlight the necessity of periodic monitoring of vector populations and control activities to reduce the risk of Leishmania transmission in this endemic area.

The Epidemiology and Ecology of Leishmaniasis

The study of transmission foci involves the clinical characterization of disease within a focus using active surveillance of human cases, characterization of the population group that is most frequently infected or at highest risk of becoming infected, diagnosis and treatment of infected people and identiication of the conceptions, atitudes, beliefs and practices related to the disease. An entomological survey is necessary to determine the geographical distribution of species and incrimination of vector species, the ecological characteristics of the zone (macro-focus), times of the year and day of highest biting activity and places in homes in which the most frequent contact between the people and the vectors occurs. A survey of peri-domestic and wild mammals in the area is advisable to try to identify potential reservoir hosts. Using this information, it is feasible to design speciic and accurate prevention and efective, rational and economic control measures and deine the times of the year and locations in which these measures must be applied.In this chapter, a description of the application of the eco-epidemiological method to the study of leishmaniasis transmission foci is provided. A special emphasis is placed on the methodology, multidisciplinary work and analysis of indings.
