1. Avaliação da utilização de colifagos como indicadores virais a partir da análise de enterovírus e adenovírus em efluentes tratados por diferentes processos biológicos
Domestic sewage contains a high amount of bacteria and other pathogens and non pathogens that are discharged into water bodies. Contamination of water by the presence of pathogenic bacteria and viruses, brings undesirable consequences, especially for public health. The objective of this work was to evaluate the possibility of using analysis of coliphages as

2. Peptídeos antimicrobianos: síntese, ensaios biológicos, estudos termodinâmicos e análise estrutural por RMN em meios biomiméticos
Many organisms employ noxious chemicals (e.g., amines, steroid derivatives, alkaloids and peptides) to defend themselves against predators and pathogenic microrganisms. Among these chemical agents stand out peptides that can be found in a wide variety of organisms including bacteria, fungi, plants, insects, fish, amphibians,arachnids and mammals. The vast ma

3. Isolamento, cultivo e identificação de bactérias com potencial uso probiótico no cultivo de organismos aquáticos: Estudo de caso com bactérias do trato gastrointestinal do linguado Paralichthys orbignyanus (Valenciennes, 1839).
Probiotic organisms are those capable to improve the health of their hosts, by assisting in the food digestion and nutrient assimilation, stimulating their immunological system or by controlling the development of pathogens. However, the use of commercial probiotics poses a serious hazard to the health of farmed animals and to the environment that must be co

4. Evaluation of Musca domestica as mechanical vector of pathogenic microrganisms in Minas frescal cheese. / Avaliação de Musca domestica como vetor mecanico de microrganismos patogenicos em queijo minas frescal.
As moscas são consideradas responsáveis pela transmissão de doenças de origem alimentar ao atuarem como vetores mecânicos de microrganismos patogênicos, como Shigella sp, Salmonella Enteriditis, Escherichia coli O157:H7, Campylobacter jejuni desde o reservatório até os alimentos. Os produtos lácteos, principalmente os produzidos artesanalmente quase

5. Utilização de pediocina em produto cárneo tipo linguiça frescal toscana para controle de Listeria monocytogenes / use of pediocins in meat products like toscana fresh sausage to control listeria monocytogenes.- seropédica:
The production of safe food with regard to pathogenic microorganisms is requirement of the legislation, being the Listeria monocytogenes one of the pathogens that must be controlled. Bactericins, among the preservations methods available in the literature, can be used to improve microbial reductions. The pediocin is a type of bacteriocin produced by the Pedi

6. Evaluation of biocide activity on biofilms formed in cutting fluid employed in metal working industry / Avaliação da atividade de biocidas em biofilmes formados a partir de fluido de corte utilizado na usinagem de metais
Biofilms are complex structures consisting of interdependent microbial species associations acting as surface colonization mechanism. Once undesirably installed at an industrial plant, biofilms contribute to contaminate many process areas, because they represent sources of microbial release and dissemination, which can deteriorate products, causing financial

7. Identificação de um novo Antígeno de Paracoccidioides brasiliensis (Lumazina Sintase) através da Técnica de IVIAT
Paracoccidioides brasiliensis is a thermally dimorphic fungus causing paracoccidioidomycosis (PCM), a mycosis that affects 10 million individuals in Latin America. The infection is acquired by inhaling airborne propagules produced by the fungal mycelium which transforms into the pathogenic yeast form, when at the body temperature. P brasiliensis expresses in

8. Air desinfection in restricted environments by combining action of titanium and ultraviolet light (TiO2/UV) / Desinfecção do ar em ambientes confinados pela ação combinada de dioxido de titanio e luz ultravioleta (TiO2/UV)
The populational growth and development of new technologies and equipments to improve quality of life can many times contribute to an increase of polluent agents and the proliferation of pathogenic ones. Respiratory-tract diseases in Brazil have been an important cause of concern and hospitable internations. Several biochemical processes are under research a

9. Ocorrencia de Enterobacter sakazakii em formulas infantis para lactentes em hospitais e maternidades da região de Campinas/SP. / Ocurrence of Enterobacter sakazakii in infant formula for sucking baby in hospitals and maternities of Campinas region.
Enterobacter sakazakii is an emergent pathogenic bacteria, recently classified by the International Commission on Microbiological Specifications for Foods (ICMSF) as "severe risk for restricted population, representing threat of death or chronic sequels of long duration". The risk population is children under 1 year old, particularly the prematures and low c
