1. Trypanosoma cruzi isolated from a triatomine found in one of the biggest metropolitan areas of Latin America
Abstract: INTRODUCTION: To characterize Trypanosoma cruzi (TcI) isolated from a Panstrongylus megistus specimen found in one of the biggest metropolitan areas of Latin America, the relationship between the TcI group of T. cruzi and the transmission cycle in the urban environment was studied. METHODS: The T. cruzi strain, Pm, was isolated in a culture med

2. History of insecticide resistance of Triatominae vectors
AbstractIn the last 15 years, different types of Triatominae resistance to different insecticides have been reported; thus, resistance may be more widespread than known, requiring better characterization and delimitation, which was the aim of this review. This review was structured on a literature search of all articles from 1970 to 2015 in the PubMed databa

3. Feeding habits of mosquitoes (Diptera: Culicidae) in an area of sylvatic transmission of yellow fever in the state of São Paulo, Brazil
AbstractBackground The reintroduction of sylvatic yellow fever in the state of São Paulo after about six decades was confirmed in the Northwestern region in 2000, where in 2008 there also occurred an important epizootic. The purpose of this study was to investigate the feeding habits of culicids potentially involved in the sylvatic transmission of the virus

4. Chagas disease: control, elimination and eradication. Is it possible?
From an epidemiological point of view, Chagas disease and its reservoirs and vectors can present the following characteristics: (i) enzooty, maintained by wild animals and vectors, with broad occurrence from southern United States of America (USA) to southern Argentina and Chile (42ºN 49ºS), (ii) anthropozoonosis, when man invades the wild ecotope and beco

5. Loops de código: automorfismos e representações / Code loops: automorphisms and representations
Neste trabalho, estudamos Loops de Código. Para este estudo, introduzimos os loops de código a partir de códigos pares e depois, provamos que loops de código de posto $n$ podem ser caracterizados como imagem homomórfica de certos loops de Moufang livres com n geradores. Além disso, introduzimos o conceito de vetores característicos associados a um loo

6. Estudos de expressão do HBsAg: hepatite B oculta, genótipos do HBV e quimeras de HBV e HCV. / Studies of expression of the HBsAg: occult hepatitis B, genotypes of the HBV and chimeras of HBV and HCV.
Introduction: Hepatitis B virus (HBV) is classified into eight genotypes (A-H) that have a distinct distribution in different geographical regions. In Brazil, genotypes A, D and F are the most prevalent. HBV infection is commonly diagnosed by the presence of the surface antigen (HBsAg) in serum. Amino acid mutations may affect HBsAg secretion levels, as well

7. A dimensão técnica nas expressões hipermidiáticas
The objective of this investigation is to help us to understand the technical dimension present in hipemediatic expressions, consubstanciated in mediatic products. This dimension is present in publications in the web, CD-Roms, DVDs, and includes productions of an artistic and educational character that use supports which possess a digital nature. It aims, th

8. Leishmania (Viannia) lainsoni (Kinetoplastida: Trypanosomatidae), a divergent Leishmania of the Viannia subgenus: a mini review
Leishmania (Viannia) lainsoni is the Leishmania species that presents the most distinct biological (morphology, growth in axenic culture medium), biochemical (enzymatic electrophoresis profile), and molecular biology characteristics, when compared to other species of the Viannia subgenus. Development of promastigote forms of this parasite attached to the wal

9. Sistemas dinamicos e controladores fuzzy : um estudo da dispersão da Morte Subita dos Citros em São Paulo / Dynamic systems and fuzzy controllers : a study of the dispersion of the Citrus Sudden Death in São Paulo
Citrus Sudden Death is a relatively new disease that has affected and killed sweet oranges grafted on the Rangpur lime. This is a worrying characteristic because the Rangpur lime amounts to 85% of the citrus orchards in São Paulo and the south of "Triângulo Mineiro". It is believed that the disease is caused by a virus transmitted by citrus aphids (vectors

10. Diversity of biting midges of the genus Culicoides Latreille (Diptera: Ceratopogonidae) in the area of the Yacyretá Dam Lake between Argentina and Paraguay
The Culicoides communities have been analyzed between 1993/1998 in the area influenced by the Yacyretá Dam Lake (Paraná River, Argentina-Paraguay). Adults of Culicoides were collected monthly by using CDC light traps exposed for 24 h in 9 sampling sites located at both margins of the river; 21 species were recorded. Highest values of species richness were

11. Cuticular hydrocarbons of Chagas disease vectors in Mexico
Capillary gas-liquid chromatography was used to analyse the cuticular hydrocarbons of three triatomine species, Triatoma dimidiata, T. barberi and Dipetalogaster maxima, domestic vectors of Chagas disease in Mexico. Mixtures of saturated hydrocarbons of straight and methyl-branched chains were characteristic of the three species, but quantitatively different

12. Development of artificial replicative plasmids for transformation of Mycoplasma pulmonis, M. capricolum and M. mycoïdes subsp. mycoïdes, and disruption of the M. pulmonis hemolysin A gene by homologous recombination / Desenvolvimento de plasmídeos replicativos artificiais para transformação de Mycoplasma pulmonis, M. capricolum e M. mycoïdes subsp. mycoïdes, e dirupção do gene da hemolisina A de M. pulmonis por recombinação homóloga
Mycoplasmas are the smallest microorganisms capable of self replication known to date, responsible for many diseases in man and animals, infecting also plants and insects. They constitute a large group of bacteria, classified in different genera in the class Mollicutes, which main common characteristic, besides the small genome, is the absence of a cell wall
