13. Listeria monocytogenes em linguiças do tipo frescal vendidas a varejo no município de Salvador-BA e eficácia do bacteriófago P100 no controle da contaminação pelo patógeno.
The outbreaks of Food-borne Diseases are a reason of concern for the food industries and public health organs. Listeria monocytogenes is known as an important pathogen causing diseases transmitted by food and its importance has been growing since the 1980s. Although the number of disease cases per year is relatively low, the infection can be serious, with le

14. Genomic variants of bacteriophages against Salmonella enterica serovar Enteritidis with potential application in the poultry industry
Salmonella enterica serovar Enteritidis (SE) is a prevalent gastrointestinal pathogen worldwide, threatening both animal and human health. In the latter, disease is associated to the consumption of SE-contaminated products from the poultry industry. The control of SE infection is largely based on the use of antibiotics and vaccines, but the use of lytic bact

15. In vitro antimicrobial activity of bacteriophages in root canals infected with clinical isolates of Enterococcus faecalis / Estudo in vitro da ação antimicrobiana de bacteriófagos em canais radiculares infectados por isolados clínicos de Enterococcus faecalis
Many studies have investigated different intracanal medications to control infection processes, especially in cases of microbial resistance to disinfection procedures. The purpose of this study was to evaluate the in vitro antimicrobial effect of specific bacteriophages on five isolates of Enterococcus faecalis, as well as the activity of a lysate cocktail i

16. In silico analysis of integrases in the phytopathogen Xylella fastidiosa: diversity, integration sites and association with bacteriophages. / Análise in-silico de integrases no fitopatógeno Xylella fastidiosa: diversidade, sítios de integração e associação com bacteriófagos.
Os elementos genéticos móveis encontrados no genoma da bactéria Xylella fastidiosa (Xf) são representados principalmente por bacteriófagos (na forma de profagos inseridos no genoma) e ilhas genômicas. As integrases são responsáveis pelo processo de mobilização (integração e/ou excisão) destes elementos, através do mecanismo de recombinação s�

17. IMPLICAÇÕES LIMNO-ECOLÓGICAS DERIVADAS DA INFECÇÃO VIRAL NO PLÂNCTON
Virus are described as the most abundant and dynamic organisms in the aquatic environment, influencing communities composition and biogeochemical and ecological processes. These organisms are responsible for great part of the bacterial and phytoplanktonic mortality, for algal blooms decrease and for increasing the nutrients and carbon availability. Many prev

18. ConstruÃÃo de uma biblioteca de anticorpos (scFv) apresentada em fagos para seleÃÃo, anÃlise e caracterizaÃÃo de antÃgenos do carrapato bovino (Boophilus microplus)
CAPÃTULO I: The amplification of fragmentos scFv (single chain fragments variable) of immunized animals is an important method to generation of monoclonal antibodies. In this work chickens had been immunized with proteins of the larval and adult phases of the Boophilus microplus for the generation of an antibodies combinatorial library. Total RNA of spleen

19. Levantamento de bacteriofagos liticos : isolamento e caracterização de virus provenientes de esgoto comum com potencial aplicação antimicrobiana / Survey of lytic bacteriophages: isolation and characterizatio of virus proceeding from raw sewage with potential antimicrobial application
Bacteriophages, viruses that infect prokaryotic hosts, are the most numerous biological entities of the world. Their abundance implied in reviews in several areas of knowledge, like genetics, evolution and ecology, and phages are now recognized as important vectors in the flux of matter, energy and information in natural environments. However, there is a hug

20. Mapeamento fÃsico e anÃlise evolutiva em Phaseolus vulgaris L. e P. lunatus L., utilizando hibridaÃÃo in situ fluorescente(FISH)
This work presents the analyses of the heterochromatin distribution and number of 5S and 45S rDNA sites in the species P. lunatus and P. vulgaris and the development of a cytogenetic map of P. lunatus based on the localization of two bacteriophages and 30 BAC (Bacterial Artificial Chromosome) of chromosomes 3, a and 7 from P. vulgaris. In both species, the c

21. Desenvolvimento de aplicações tecnológicas da metodologia de phage display no diagnóstico do câncer de próstata
Prostate cancer is the second cause of death in men by tumor, surpassed only by lung cancer. Its occurrence is estimated to be 51 to 100,000 cases per year. The increasing incidence levels observed may be partially explained by the evolution of diagnostic methods, quality of information systems and longer life expectancy. The identification of new cancer spe

22. Isolamento, caracterização e regulação de genes que codificam pectato liase em Crinipellis perniciosa, agente etiológico da vassoura-de-bruxa do cacaueiro (Theobroma cacao) / Isolation, characterization and regulation of genes encoding pectate lyase in Crinipellis perniciosa, etiological agent of the witches broom in cocoa (Theobroma cacao)
In this work, genes encoding the pectinolytic enzyme pectate lyase were isolated from the genome of the fungus Crinipellis perniciosa, etiological agent of the witches broom disease of cocoa. Pectinolytic enzymes have been correlated with the pathogenicity of some phytopathogenic fungi. Preliminary database searches of the Genome Project Witches broom, revea

23. Use of lytic bacteriophages to reduce Salmonella Enteritidis in experimentally contaminated chicken cuts
Reducing Salmonella contamination in poultry is of major importance to prevent the introduction of this microorganism into the food chain. Salmonellae may spread during storage time (shelf life) whenever pre-harvest control fails or post-harvest contamination occurs. Therefore, preventive measures should also be used in the post-harvest level of poultry prod
