13. Caracterização biológica, antigência e genética de amostras de vírus da raiva isoladas de animais domésticos e de seres humanos no Estado do Maranhão / Biological, antigenic and genetic characterization of rabies virus samples isolated from domestic animals and humans in Maranhão State
Analisou-se 54 amostras de vírus da raiva isoladas de diferentes espécies animais e de seres humanos do Estado do Maranhão, inicialmente pelas técnicas tradicionais de imunofluorescência direta (IFD) e de inoculação intracerebral em camundongos (ICC), com o objetivo de realizar um estudo de epidemiologia da doença. No reteste, todas as amostras foram

14. Expressão heteróloga, purificação e caracterização de proteínas transmembrana de Mycoplasma hyopneumoniae / Heterologous expression, purification and characterization of transmembrane protein of Mycoplasma hyopneumoniae
Mycoplasma hyopneumoniae is the etiological agent of swine enzootic pneumonia (EP), one the most common respiratory diseases of pigs worldwide. The disease is characterized by retarded growth rate in animals of mid-finishing to slaughter age, causing significant economic losses to swine production. Vaccination is the most cost-effective strategy for the cont

15. Avaliação da resposta humoral a antígenos de Lacazia loboi utilizando soros de pacientes com lacaziose
Jorge Lobos disease is a mycosis of the skin and subcutaneous tissue caused by Lacazia loboi, a fungus that presents phenotypic similarities to Paracoccidioides brasiliensis. Because it resists culture, research to characterize and isolate its DNA and antigenic proteins has been a problem. Thence, most previous serological studies have used antigens from P.

16. Avian metapneumovirus : susceptibility at different cell lines and production of monocioinal antibodies / Metapneumovirus aviario : suscetibilidade em diferentes sistemas celulares e produção de anticorpos monoclonais
Avian Metapneumovirus (AM PV) , also denominated virus of the rhinotracheitis of the turkeys, it is a virus that attacks and it causes infection in the upper respirator) tract of chickens and turkeys. Besides the respiratory infection, in breeders and layers is associated with a significant fall in the production of eggs. In chickens the virus is related wit

17. Epidemiologia molecular dos vírus dengue em Goiânia-GO, 1994 - 2006: vigilância laboratorial e caracterização dos sorotipos circulares / Molecular epidemiology of dengue virus in Goiânia, 1994-2006: laboratorial surveillance and characterization of circulate serotypes
Nowadays, dengue constitute the major public health problem, because is relevant cause of illness and death between thousands people that resident in the tropical and subtropical regions in world. The dengue virus is classified as four serotypes (DENV-1, 2, 3 and 4) according to antigenic differences and characterized intra-typical groups called genotypes. T

18. Antigenic and genomic characterization of adenovirus associated to respiratory infections in children living in Northeast Brazil
From January to December 1998, nasopharyngeal aspirates were obtained from 482 children with acute respiratory infections attended in emergence department and wards of a teaching hospital in the city of Salvador, Brazil. The samples were tested for the presence of adenovirus by isolation in tissue culture and indirect immunofluorescence assay. Eleven adenovi

19. Microsatellite characterization of Plasmodium falciparum from symptomatic and non-symptomatic infections from the Western Amazon reveals the existence of non-symptomatic infection-associated genotypes
In Western Amazon areas with perennial malaria transmission, long term residents frequently develop partial immunity to malarial infection caused either by Plasmodium falciparum or P. vivax, resulting in a considerable number of non-symptomatically infected individuals. For yet unknown reasons, these individuals sporadically develop symptomatic malaria. In o

20. Trypanosoma cruzi ribosomal protein S4: characterization of its coding locus, analysis of transcripts, and antigenicity of the protein
Two allelic genomic fragments containing ribosomal protein S4 encoding genes (rpS4) from Trypanosoma cruzi (CL-Brener strain) were isolated and characterized. One allele comprises two complete tandem repeats of a sequence encoding an rpS4 gene. In the other, only one rpS4 gene is found. Sequence comparison to the accessed data in the genome project database

21. A preliminary survey of M. hyopneumoniae virulence factors based on comparative genomic analysis
Mycoplasma hyopneumoniae is the etiological agent of porcine enzootic pneumonia (PEP), a major problem for the pig industry. The mechanisms of M. hyopneumoniae pathogenicity allow to predict the existence of several classes of virulence factors, whose study has been essentially restricted to the characterization of adhesion-related and major antigenic protei

22. Estabilidade antigênica e patogenia de amostras do vírus rábico após sucessivas inoculações em camundongos. / Antigenic stability and patogeny on rabies virus strains After consecutive inoculations in mice
A raiva é uma zoonose causada pelo vírus da raiva (VR), um membro do gênero Lyssavirus da família Rhabdoviridae. Apesar do VR ser considerado antigenicamente estável, amostras com variações antigênicas têm sido detectadas. Na busca de identificar possíveis variantes circulantes no Brasil, um dos objetivos do presente estudo foi identificar as carac

23. Identificação e caracterização de peptídeos miméticos dos antígenos de Mycobacterium leprae por phage display
CHAPTER I: Leprosy presents a clinical spectrum that spans from a strong cellular mediated immunity and bacili growth control of Mycobacterium leprae at the tuberculoid pole to a poor T cell immunity with extensive bacterial load at the lepromatous pole. The antigenic profile characterization in both clinical forms is a necessary step for discover and evalua

24. Cloning, expression and characterization of an antigenic domain of the a major surface protein recombinant NcSRS2 (Nc1-p43) of Neospora caninum. / Clonagem, expressão e caracterização do domínio antigênico da proteína majoritária de superfície NcRS2 (Nc1-p43) recombinante de Neospera caninum
Neospora caninum is an obligate intracellular protozoan that can infect domestic and wild canids, as well as ruminants and equines. It was described in 1988 as causing neuromuscular alterations and death in dogs. Recently, N. caninum has received considerable attention for its large impact on the dairy industry, given the economic losses related to breeding
