Abstract (Summary)
American Cutaneous Leishmaniosis ? ACL and American Visceral - AVL are non-contagiousinfect-parasitic diseases of zootic character, caused by protozoa of several species of thegender Leishmania that attack man, several species of domestic and wild animals. Thesediseases are considered re-emerging infections that reappear or are spread out in a way theycan reach other areas in which its presence had not been noticed before. The World HealthOrganization considers ACL as being the second most important disease caused by protozoawhen it concerns public health. The vectors of ACL and of AVL are phlebotomine of theLutzomyia genus. Worldwide about 800 species are known of which 229 are found in Brazil.Of these approximately 40 species are considered either suspect or proved to beLeishmaniosis vectors. The objective of this work was to monitor the phlebotominic faunarelating it to environmental alterations and climatic elements. The researched area was the oneof construction of the barrage of the Hydroelectric Power Plant ?Capim Banco I, in Araguaririver basin, in Uberlândia, MG, before and during the construction, and after the filling of thelake. The barrage of the Hydroelectric Plant ?Capim Branco I? was built in the latitude 18°47'25"S and longitude 48°08'50"W, in the Km 150 of Araguari river, starting in its. Thisresearch was accomplished from May 2003 to December 2006, being initiated by ademarcation of the plots for captures. Two capture plots were chosen in the area of theHydroelectric Plant. The first plot was set beside the bridge of Pau Furado and the secondone approximately 184m of the edge of the river. To capture the phlebotomine Shanon trapswere used with the light of a gas lantern with screens of 500 candles, 3 luminous traps ofCDC type (Center on Disease Control), with 6-volt batteries each, and suction tube, capturerof Castro. In order to study the environmental dynamics of the area, an Ecological Profile wasdeveloped. 87 captures were accomplished with 522 hours of field work and 1500 hours oflaboratory work. 301 phlebotomine of two genders being 160 Brumptomyia and 141Lutzomyia. 199 were captured in the CDC traps and 104 in the Shannon trap. 135 were maleand 166 female. The capture of two species responsible for carrying ACL (L. whitmani and L.neivai) and the species responsible for carrying AVL in the Southeast Area (L. longipalpis),shows the necessity of a System of Environmental Surveillance in Health with preventionactions and phlebotomine control, in order to avoid risks to the residents of the settlement"Vila Nova" as well as to the visitors looking for leisure and fishing.
