“…In this study, the presence of the parasite in different tissues indicates its localization in the body, for example, in the blood and skin, with visceralization indicated by its detection in the bone marrow and spleen. Similar results have also been reported by others (Nery-Guimarães et al, 1968;Lainson et al, 1981;Roque et al, 2010).…”

Leishmania nested PCR (LnPCR) targeted to the SSUrRNA gene and DNA sequencing were used to analyze 315 tissue samples from 80 Rattus norvegicus specimens trapped in an area endemic for leishmaniasis in Belo Horizonte, Minas Gerais, Brazil. Of the samples analyzed, 17.46% (55/315) of all tissues, 10% (8/80) of skin, 26.92% (21/78) of blood, 30.76% (24/78) of bone marrow and 2.53% (2/79) of spleen were positive for Leishmania. The overall infection prevalence was 36.25% (29/80) The DNA sequencing showed that 65.51% (19/29) of the positive animals were infected by parasites belonging to the Leishmania braziliensis complex. The identification of L. braziliensis DNA in R. norvegicus in an area with a high prevalence of leishmaniasis might imply a zoonotic role of this species. The rodent control programs and health education may represent important measures toward the control of leishmaniasis.

“…They bred well and we were soon able to move our small colony to an animal house that we had adapted from an old generator shed. Otis Causey's discovery led to two publications in 1964 16,17 and two more in 1966 18,19 . The IEC was created in 1936 under the name of the "Instituto de Pathologia Experimental do Norte" (IPEN), to study visceral leishmaniasis in Pará State 2 .…”

“…Reports of wild reservoirs infected by Leishmania spp. emphasize the zoonotic character of ACL [5] and increased the importance of studies of domestic and peridomestic animals as spreading agents of the parasite to humans. A number of rodent, marsupial, and wild canid species were identified as natural hosts and potential reservoirs for Leishmania spp.…”

In the present study we surveyed the fauna of phlebotomine sand flies and small mammals in peridomestic areas from a Brazilian municipality where the American cutaneous leishmaniasis (ACL) is endemic. A total of 608 female phlebotomine sand flies were captured during nine months in 2009 and 2010. Seven different species were represented with 60% of them being Lutzomyia intermedia and Lu. whitmani, both incriminated vectors of ACL. Lu. longipalpis, a proven vector of visceral leishmaniasis (VL) was also captured at high proportion (12.8%). Genomic DNA analysis of 136 species-specific pools of female sand flies followed by molecular genotyping showed the presence of Leishmania infantum DNA in two pools of Lu. longipalpis. The same Leishmania species was found in one blood sample from Rattus norvegicus among 119 blood and tissue samples analysed. This is the first report of Le. infantum in R. norvegicus in the Americas and suggests a possible role for this rodent species in the zoonotic cycle of VL. Our study coincided with the reemergence of VL in Governador Valadares.
