1. Chemical composition and antibacterial activity of essential oils from Citrus aurantifolia leaves and fruit peel against oral pathogenic bacteria
ABSTRACT Tooth decay is a major public health problem which affects a large number of people in several countries. Even though more than 700 bacterial species have been detected in the oral cavity, Streptococcus and Lactobacillus stand out as the genera that cause tooth decay and other periodontal diseases. In this study, essential oils from Citrus aurantifo

2. Isolation, identification, and biocontrol of antagonistic bacterium against Botrytis cinerea after tomato harvest
ABSTRACT Tomato is one of the most important vegetables in the world. Decay after harvest is a major issue in the development of tomato industry. Currently, the most effective method for controlling decay after harvest is storage of tomato at low temperature combined with usage of chemical bactericide; however, long-term usage of chemical bactericide not onl

3. Antimicrobial activity of ozone and NaF-chlorhexidine on early childhood caries
Abstract An early childhood carie (ECC) is an extremely destructive form of tooth decay. The aim of this study was to investigate the action of ozone (O3), and the association of sodium fluoride (NaF) with chlorhexidine (CHX) on bacteria related to ECC. Overnight culture of the bacteria was performed. On exponential phase the suspension was adjusted (101-108

4. Decaimento bacteriano em lagoas de estabilização no Nordeste brasileiro
Lagoas de estabilização consistem no sistema de tratamento de esgotos mais utilizado no Rio Grande do Norte (RN), Brasil, correspondendo a cerca de 90% de todos os sistemas. As bactérias fecais são removidas principalmente nas lagoas facultativas e de maturação. Muitos fatores influenciam no decaimento de bactérias, como: os níveis de pH e OD, temper

5. Passive acquisition of protective antibodies reactive with Bordetella pertussis by the newborn via placental transfer and breastfeeding / Aquisição passiva de anticorpos protetores reativos com Bordetella pertussis pelo recém-nascido via transferência placentária e aleitamento materno
Pertussis is currently considered an important public health problem in developed countries. Although there is no evidence of an increase in the number of pertussis cases in our country, can not rule out the hypothesis of a future re-emergence of disease, as epidemiological data from some regions show an increase in incidence, indicating that probably there

6. CEFALOSPORINAS E SURFACTANTE NÃO-IÔNICO EM EFLUENTE HOSPITALAR: DETERMINAÇÃO, DEGRADAÇÃO POR MEIO DE FOTÓLISE E ELETROCOAGULAÇÃO E IDENTIFICAÇÃO DE SUBPRODUTOS E METABÓLITOS / CEFALOSPORINS AND NON IONIC SURFACTANTS IN HOSPITAL WASTEWATER: DETERMINATION, DEGRADATION BY MEANS OF PHOTOLYSIS AND ELECTROCOAGULATION AND IDENTIFICATION OF BYPRODUCTS AND METABOLITES
The currently incorrect and excessive consumption of pharmaceuticals and surfactants, mainly domestic usage, has become a concern to the scientific community around the world, due to the environmental consequences with regard to the bacterial resistance (characteristic of antibiotics), and alteration of hormonal systems (provoked by the degradation products

7. Caracterização e comportamento de uma série de lagoas de polimento tratando esgotos sanitários / Characterization and performance of a polishing pond series treating domestic wastewater
This work, conducted in Viçosa MG, presents the results of five years monitoring of a domestic wastewater treatment system including an anaerobic reactor (UASB) plus a submerged aerated biofilter (real scale), followed by a three to four shallow polishing / maturation ponds series (pilot scale, h ≤0,90 m), with operational flexibility in terms of dept

8. Solar Disinfection Evaluation and its Social Viability at State of Ceará, Brazil / Avaliação do Processo de Desinfecção Solar (SODIS) e de sua Viabilidade Social no Estado do Ceará
Despite the importance of sanitation for well-being of the mankind and the natural resources conservation, still today a large number of people do not have access to wastewater system neither to public water supply. One technique which has being studied and applied in developing countries as a safe household water treatment method is solar disinfection, SODI

9. Potencial cariogenico "in vitro" de estreptococos grupo mutans da cavidade bucal e seu significado em relação a carie dentaria
In order to analyze the cariogenic potential of some group mutans streptococci species, isolated and in association, by formation of "in vitro" bacterial plaque, production of extracellular polysaccharides and acid production capacity, strains of those microorganisms belonging to the microbial collection of Microbiology and Immunology Laboratory, Dental Scho

10. Benthic and Pelagic Viral Decay Experiments: a Model-Based Analysis and Its Applicability
The viral decay in sediments, that is, the decrease in benthic viral concentration over time, was recorded after inhibiting the production of new viruses. Assuming that the viral abundance in an aquatic system remains constant and that viruses from lysed bacterial cells replace viruses lost by decay, the decay of viral particles can be used as a measure of v

12. Decay-Accelerating Factor and Cytoskeleton Redistribution Pattern in HeLa Cells Infected with Recombinant Escherichia coli Strains Expressing Dr Family of Adhesins
Escherichia coli strains expressing Dr fimbriae are able to enter epithelial cells by interacting with a complement-regulatory protein, decay-accelerating factor. This model of bacterial internalization, with a well-characterized bacterial ligand and host receptor, provides a unique opportunity to investigate the early stages of invasion. We used immunofluor
