“…10, * Embora o número de exemplares de M. migonei tenha sido irrelevante do ponto de vista estatístico, sua importância na epidemiologia da LTA não pode ser desconsiderada, uma vez que no Estado de São Paulo esse inseto foi associado à transmissão de LTA. 2 Constatou-se que nos dois períodos de coletas a AF1, independentemente da isca animal utilizada, teve menor rendimento. Esse fato pode estar relacionado à posição na qual a armadilha se encontrava, ao lado de uma via de acesso às residências.…”

Estudo dos hábitos alimentares de flebotomíneos em área rural no sul do BrasilHost feeding preferences of sandflies in rural area, Southern Brazil RESUMO OBJETIVO: Investigar a composição específica e aspectos da preferência alimentar de flebotomíneos em relação aos animais domésticos existentes em área endêmica de leishmaniose tegumentar americana. MÉTODOS:Os flebotomíneos foram coletados nos meses de janeiro a abril de 2004, das 20 às 24h, numa área situada a 40 m de uma das residências de um sítio localizado no município de Mandaguari, PR, sul do Brasil. Foram usadas quatro armadilhas luminosas de Falcão, instaladas a 5 m de distância uma da outra, ao lado de uma gaiola, cada uma delas contendo isca animal (suíno, cão, coelho e galinha). RESULTADOS: ABSTRACT OBJECTIVE:To investigate the fauna and host feeding preferences of sandflies as for domestic animals in an endemic area of American cutaneous leishmaniasis. METHODS:The sandflies collections were carried out from 8:00 pm to 12:00 am in an area 40 meters away from one of the residences in a farm in Southern Brazil, between January and April, 2004. Collection was performed using four Falcão light traps, placed 5 m apart from each other beside a cage, each one of them containing an animal bait (swine, dog, rabbit, and chicken). RESULTS:A total of 1,697 specimens of sandflies were collected as follows: Nyssomyia whitmani, Pintomyia fischeri, Migonemyia migonei, Nyssomyia neivai, Pintomyia pessoai and Psathromyia shannoni. The prevalent species was N. whitmani. There were no feeding preferences of sandflies as for the animals studied. CONCLUSIONS:N. whitmani and P. fischeri are opportunistic species and female

“…whitmani, however, has been regarded to be a species "under adaptation" to the urban environment by several investigators due to the fact that it is collected in high concentrations in thickly forested areas and in peridomiciliary areas of large centers (Camargo-Neves et al 2002, Dos Santos et al 2003, Salomón et al 2003, Oliveira et al 2003 and it has been associated with peridomiciliary transmissions in Brazilian Northeastern and Southeastern areas (Cuba-Cuba et al 1985, Azevedo & Rangel 1991, Rangel et al 1996. Due to this fact, several studies have been undertaken in order to better understand the biology of L. whitmani.…”

“…Moreover, infection in humans depends on their relationship with the chain of parasite transmission (ASHFORD, 2000;LAINSON, 1985). The latest surveys of phlebotomine fauna conducted in some areas of São Paulo have determined that Lutzomyia intermedia is the most abundant species in this state (SHIMABUKURO & GALATI, 2011;SILVA et al, 2012), which coincides with findings of infection by L. (V.) braziliensis (CAMARGO-NEVES et al, 2002). In contrast, L. flaviscutellata, the vector species of L. (L.) amazonensis, has not been found.…”

Leishmaniasis is a major public health problem worldwide. Because Leishmania can adapt to new hosts or vectors, knowledge concerning the current etiological agent in dogs is important in endemic areas. This study aimed to identify the Leishmania species detected in 103 samples of peripheral blood from dogs that were naturally infected with these protozoa. The diagnosis of leishmaniasis was determined through parasitological examination, the indirect enzyme-linked immunosorbent assay (ELISA) and the polymerase chain reaction (PCR). The Leishmania species were identified by means of PCR-restriction fragment length polymorphism (PCR-RFLP). The samples were subjected to PCR using oligonucleotide primers that amplify the intergenic region ITS1 of the rRNA gene in order to identify the species. The amplified DNA was digested using the restriction enzyme HaeIII. A restriction profile identical to L. amazonensis was shown in 77/103 samples and the profile was similar to L. infantum in 17/103. However, a mixed profile was shown in 9/103 samples, which impeded species identification. In conclusion, the infection in these dogs was predominantly due to L. amazonensis, thus indicating that diagnosing of cases of canine leishmaniasis needs to be reexamined, since the causative agent identified is not restricted to L. infantum.
