Characterization of Leishmania spp. causing cutaneous leishmaniasis in Manaus, Amazonas, Brazil

In the State of Amazonas, American tegumentary leishmaniasis is endemic and presents a wide spectrum of clinical variability due to the large diversity of circulating species in the region. Isolates from patients in Manaus and its metropolitan region were characterized using monoclonal antibodies and isoenzymes belonging to four species of the parasite: Leishmania (Viannia) guyanensis, 73% (153/209); Leishmania (Viannia) braziliensis, 14% (30/209); Leishmania (Leishmania) amazonensis, 8% (17/209); and Leishmania (Viannia) naiffii, 4% (9/209). The most prevalent species was L. (V.) guyanensis. The principal finding of this study was the important quantity of infections involving more than one parasite species, representing 14% (29/209) of the total. The findings obtained in this work regarding the parasite are further highlighted by the fact that these isolates were obtained from clinical samples collected from single lesions

RECONFIGURABLE ARCHITECTURE PROPOSAL APPLIED TO MOBILE ROBOTS

Abstract. Due to the fast innovation speed in the hardware and software technologies in the field of embedded systems, it becomes more and more necessary to develop applications based on methodologies, which take into account the easiness of future modifications, updates and improvements in the designed system. According to these requirements, this work presents a proposal of environment using reconfigurable computing applied to mobile robots prototype design. The developed software and hardware are structured in independent blocks, through open architecture implementation, allowing the easy expansion of the syste m, better adapting the mobile robot to the tasks associated to it. Keywords. Open Control Architecture, Reconfigurable computing, Mobile Robots, Embedded Systems. 1
