Introduction:The sand fly, Lutzomyia longipalpis, is the main vector of Leishmania infantum in the Americas, primarily occurring in areas of apparent anthropomorphic modifications in several regions of Brazil. Methods. Sand flies were captured using light traps. Results: Out of all captured species, Lu. longipalpis numbers had increased within the park. Conclusions: We report the occurrence of Lu. longipalpis in an area of Atlantic Forest, possibly representing the first sylvatic population of Lu. longipalpis in an area absent of peridomestic captures, but with the risk of L. infantum transmission in the areas of Niterói and Maricá.

“…Lu. longipalpis has also been observed in other sylvatic environments (4) (12) ; however, it tends to dominate other sand fly species in modified or urbanized areas (13) (14) . Furthermore, climatic factors, such rain, humidity, and temperature, appear to directly influence the seasonality of Lu.…”

“…Several recent scientific studies describe this expansion; in terms of hosts, Souza et al (2005), Dorval et al, (2010) and Cardoso et al (2015) reported Felis catus domesticus (domestic cat), Mesocricetus auratus (hamster) and Necromys lasiurus (wild rodent) infection. In terms of geographical distribution, Dorval et al (2006), Marlow et al (2013) and Carvalho et al (2013) reported its detection in Mato Grosso do Sul, Santa Catarina and Rio de Janeiro states, Brazil.

Leishmania in synanthropic rodents (Rattus rattus):new evidence for the urbanization of Leishmania (Leishmania) amazonensis AbstractThis study aimed to detect parasites from Leishmania genus, to determine the prevalence of anti-Leishmania spp. antibodies, to identify circulating species of the parasite, and to determine epidemiological variables associated with infection in rats caught in urban area of Londrina, Paraná, Brazil. Animal capture was carried out from May to December 2006, serological and molecular methods were performed. DNA was extracted from total blood, and nested-PCR, targeting SSu rRNA from Leishmania genus, was performed in triplicate. The positive samples were sequenced twice by Sanger method to species determination. In total, 181 rodents were captured, all were identified as Rattus rattus and none showed clinical alterations. Forty-one of the 176 (23.3%) animals were positive for Leishmania by ELISA and 6/181 (3.3%) were positive by IFAT. Nine of 127 tested animals (7.1%) were positive by PCR; seven were identified as L.

L. migonei was found naturally infected in the municipality of São Vicente Ferrer, Pernambuco (5) and in the State of Rio de Janeiro (6) (7) . However, its role in the epidemiology of VL in Brazil needs to be elucidated.…”

“…In Brazil, two species are involved in transmission of visceral leishmaniasis (VL), namely Lutzomyia longipalpis and Lutzomyia cruzi (4) . Lutzomyia migonei specimens were found to be naturally infected with Leishmania infantum, in São Vicente Ferrer, Pernambuco (5) and Rio de Janeiro (6) (7) . An experimental infection with L. infantum was reported in a previous study (8) .…”

Introduction:The sandfl y fauna is well studied globally. In Brazil, sandfl y fauna is very diverse in the Northeast region, especially in states such as Maranhão, Ceará, and Bahia. However, in the State of Pernambuco, the distribution of these insects is still not well known. Therefore, the objective of this study was to identify the different species that constitute the sandfl y fauna in an urban area in the Northeast region of Brazil, where an outbreak of visceral leishmaniasis (VL) was recently reported. Methods: The sandfl ies were collected from an urban area endemic for VL, at fi ve collection points. The collection of samples was carried out from November 2014 to December 2015, using CDC light traps installed in intradomiciliary and peridomiciliary fashion. Results: The collected sandfl ies (n = 297) belonged to eight species: Lutzomyia lenti, Lutzomyia longipalpis, Lutzomyia sallesi, Lutzomyia migonei, Lutzomyia walkeri, Lutzomyia capixaba, Lutzomyia carmelinoi, and Lutzomyia whitmani. Most of the specimens collected were peridomiciliary (247/297, 83%). L. lenti (154/297, 52%) was the most frequently sampled species, followed by L. longipalpis (88/297, 29.6%), and L. sallesi (42/297, 14.1%), which together accounted for over 90% of the collected sandfl y specimens. Conclusions: The continued presence of L. longipalpis in urban areas, including that in intradomiciliary areas, with a predominance of females, is crucial because of the high possibility of them causing VL outbreaks, since this species is the main vector of Leishmania infantum in Brazil.
