25. Vascular supply of the central nervous system of the land snail Megalobulimus oblongus (Gastropoda, Pulmonata)
The vascularization of the central nervous system of the snail Megalobulimus oblongus was studied by injection of carmine-gelatin solution into the arterial system and using a histochemical technique for the detection of alkaline phosphatase. The central nervous system of M. oblongus is irrigated by the anterior aorta, from which a series of small branches e

27. Respostas imunológicas e mecânicas em população suscetível e resistente Plutella xylostella (L.) (Lepidoptera : Plutellidae) frente a formulações comerciais à base de Bacillus thuringiensis Berliner / Immunologicals and mecanicals responses in susceptible and resistant population of Plutella xylostella (L.) (Lepidoptera : Plutellidae) stand up to commercials formulations of Bacillus thuringiensis Berliner
The resistance of Plutella xylostella (L.) (Lepidoptera: Plutellidae) has been attributed to many mechanisms as alterations in cell membrane receptors on midgut and the immune response to Bacillus thuringiensis Berliner toxin. The research tested the possibility that after expositions to Bt formulations, insects from a susceptible population (SP) and a resis

28. PHENANTHRENE AND ALKYL HOMOLOGOUS METABOLITES FORMATION AND IDENTIFICATION IN CRAB UCIDES CORDATUS / FORMAÇÃO E IDENTIFICAÇÃO DE METABOLITOS DE FENANTRENO E HOMÓLOGOS ALQUILADOS EM CARANGUEJO UCIDES CORDATUS
The main goal of this study was to evaluate the formation of phenanthrenes metabolites, parental and alkylated, in crabs Ucides cordatus urine. Laboratory experiments were carried out exposing organisms to phenanthrene (2 ug.kg-1 and 3 ug.kg-1), to the phenanthrene homologues alkylated, 1-methylphenanthrene and 2,6,9-trimethylphenanthrene (0,0125 ug.kg-1 and

29. Infecção por Hepatozoon sp. em cães da área urbana do município de Uberlândia, Minas Gerais, Brasil
Hepatozoonosis is a disease that affects dogs and it is transmitted by the ingestion of infected ticks with the oocyst of the Hepatozoon sp.. This study was held in order to determine the occurrence of this parasite in the urban área of the city of Uberlândia, Minas Gerais, Brazil, using the blood smear, to compare the best collecting methodology for the d

30. Interaction of Metarhizium anisopliae (Metsch), Beauveria bassiana (Bals.) and granulovirus, the main pathogens of Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae) / Interação de Metarhizium anisopliae (Metsch.), Beauveria bassiana (Bals.) e vírus da granulose, principais patógenos de Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae)
The sugarcane borer, Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) is naturally infected by various pathogens, the most important are Metarhizium anisopliae (Metsch) (Ascomycota: Clavicipitaceae), Beauveria bassiana (Bals.) (Ascomycota: Cordycipitaceae) and granulovirus. These microorganisms may coinfect the same host under field conditions

31. Análise de expressão e splicing alternativo do gene Mdh-1 de Apis mellifera L. (Hymenoptera: Apidae)
Mdh-1 enzyme locus coding for cytoplasmic malate dehydrogenase has three common alleles Mdh-1100 (F), Mdh-180 (M) e Mdh-165 (S) and it has been extensively used as racial marker in populational studies of Apis mellifera. Additional isoforms are detected by electrophoretic analysis during ontogenetic development of A. mellifera, indicating differential expres

32. Susceptibility of Rosa Shrimp Farfantepenaeus subtilis (Pérez-Farfante, 1967) to Infectious myonecrosis virus (IMNV) / Susceptibilidade do Camarão Rosa Farfantepenaeus subtilis (Pérez-Farfante, 1967) ao Vírus da Mionecrose Infecciosa (IMNV)
Viral diseases are causing great damage in shrimp farming. With the IMN virus emergence in Northeastern Brazil in 2002, the shrimp producers faced an unknown disease that caused significant losses for the industry. Thus, a better knowledge about this disease and the investigation of how other species of shrimp are affected by the IMN virus will be an importa

33. Análise da expressão de regiões da proteína Circumsporozoíta de Plasmodium sp. em Aedes aegypti infectado por Plasmodium gallinaceum. / Expression analyses of Plasmodium sp. Circumsporozoite protein regions in Plasmodium gallinaceum infected Aedes aegypti.
Transgenic mosquitoes that impair malaria transmission can be an alternative control but currently an effective line is not available. A better understanding of mosquito interaction with pathogens is very important to improve refractory transgene design. Circumsporozoite protein (CSP) has two conserved domains that could be involved in spz penetration into m

34. Study of proteins obtained from Lonomia obliqua hemolymph with antiviral activity / Estudo de proteínas obtidas de hemolinfa de Lonomia obliqua com ação antiviral
Diversos trabalhos têm demonstrado a presença de peptídeos bioativos em hemolinfa de insetos e seu potencial uso como agentes terapêuticos. Este trabalho buscou identificar e isolar proteínas da hemolinfa de Lonomia obliqua com ação antiviral. A adição de hemolinfa antes da infecção reduziu o título de poliovírus de 1,5x107 TCID50/mL no cultivo

35. Pathogenicity of the fungi genus Isaria (Persoon) on Coptotermes gestroi (Wasmann) (Isoptera : Rhinotermitidae) and immunologic aspects / Patogenicidade de fungos do gênero Isaria (Persoon) sobre Coptotermes gestroi (Wasmann) (Isoptera : Rhinotermitidae) e aspectos imunológicos
The termite Coptotermes gestroi (Wasmann) is an urban and agricultural pest that has been established in many areas of the world. The use of entomopathogenic fungi is an option to minimize the economic loss caused by this termite. It is known, however, that physiological disorders caused by a pathogen trigger defence reactions of the insects, such as humoral

O cupim Coptotermes gestroi (Wasmann) é uma praga urbana e agrícola que vem se estabelecendo em muitas áreas do mundo. A utilização de fungos entomopatogênicos é uma opção para minimizar os prejuízos econômicos causados por este cupim. Sabe-se, contudo, que distúrbios fisiológicos ocasionados por um patógeno desencadeiam reações de defesa pel
