Avaliação da atividade antimicrobiana das defensinas recombinantes de ervilha (drr230a) e café (cd1) produzidas em Pichia pastoris

The inefficiency of chemical pesticides to control phytopathogenic fungi in agriculture and the frequent incidence of human diseases caused by bacteria which are resistant to antibiotics lead to the search for alternative antimicrobial compounds. In this context, plant defensins are a promising tool for the control of both plant and human pathogenic agents. Plant defensins are cationic peptides of about 50 amino acid residues, rich in cysteine and whose tridimensional structure is considerably conserved among different plant species. These antimicrobial molecules represent an important innate component from plant defense response against pathogens and are expressed in various plant tissues, such as leaves, tubers, flowers, pods and seeds. The present work aimed at the evaluation of the antimicrobial activity of two plant defensins against different phytopathogenic fungi and pathogenic bacteria to humans. The defensin Drr230a, whose gene was isolated from pea (Pisum sativum), and the defensin CD1,whose gene was identified within coffee (Coffea arabica) transcriptome, were subcloned in yeast expression vector and expressed in Pichia pastoris. The gene cd1 was subcloned as two different recombinant forms: CD1tC, containing a six-histidine sequence (6xHis) at the peptide C-terminal region and CD1tN, containing 6xHis coding sequence at the N-terminal region. In the case of the defensin Drr230a, the 6xHis coding sequence was inserted only at the N-terminal region. Assays of the antimicrobial activity of the purified recombinant proteins rDrr230a and rCD1 against Phakopsora pachyrhizi, causal agent of soybean Asian rust, were performed to analyze the in vitro spore germination inhibition and disease severity caused by the fungus in planta. Both recombinant defensins were able to inhibit P. pachyrhizi uredospore germination, with no difference between the antimicrobial action of either CD1tC or CD1tN. Moreover, rDrr230a and rCD1 drastically reduced severity of soybean Asian rust, as demonstrated by in planta assays. In spite of the fact that rCD1 was not able to inhibit proliferation of the human pathogenic bacteria Staplylococcus aureus and Klebsiella pneumoniae, rCD1 was able to inhibit growth of the phytopathogenic fungus Fusarium tucumaniae, that causes soybean sudden death syndrome. The obtained results show that these plant defensins are useful candidates to be used in plant genetic engineering programs to control agriculture impacting fungal diseases.

Análise de qualidade da atenção à criança na estratégia saúde da família: o óbito infantil evitável como referência

Alma-Ata declaration bring the Primary Attention to the Health (PAH) as first level of health attention for individuals, family and community, which considers infant group as priority. Several initiatives that gave bases to integral attention to the children health formalized in the principles of Unique Health System. Family Health Strategy (FHS) comes to strengthen this attention, instituting new ways of work organization and professional practices that gave impact in their quality indicators. One of them is children mortality, showing decline in their values. Though, studies indicates persistence of avoidable infant deaths. In Natal RN, this reality is also perceptible leading to inquietudes, mainly at the space of services production, it means, which motivated the accomplishment of the present study intending to analyse the way that the organizational and structural processes as long as the professional practices in FHS interfered in the quality of children s health attention who died by avoidable death in the year of 2007 in municipal district of Natal-RN. It treats, therefore, to an exploratory and descriptive survey of cases study type, thar had as primary sources the oficial documents of MH, the family prontuary, pregnant card, child card and testimony obt ined from instrument of research elaborated based in investigation form of infant death by MH, applied to 10 mothers of children who had avoidable death. In analysis it was appealed silmultaneous triangulation of methods and sources, allowing a bigger aproximation from obtained informations. To elucidate the cases, the aspects studied were analyzed to the light of explicative model of Social Determinants of Health. Among individual and family aspects were highlighted the related to age, schooling, family habits and customs and mother s economic condition, besides of pregnancy age, newborn weight and associated diseases, which don t differ from literature about the theme. Reffering to the factors organizational and structural processes and professionals practice, highlihgted, the treatment given by the professionals, the territorialization and adscription of areas, the difficulty of having access to the services or sleepers and the reference and counterreference. But also, the ausence or few greet, the lack of communication, few assiduity and ponctuality by professionals in service, among others. In a general way mothers considers the attendance received in the hospital good and very good , opnions that in the Basic Attention weren t so favorable, in spite of many of predictible actions in this level have been performed in the studied cases. It is observed, therefore, that the social determinants of health has a strong influence in ocurrence of infant deaths, what implicates in a large actuation by Infant Mortality Committee from municipal district. This way, it becomes fundamental the reflection and evaluation about the effectiveness and execution by the processes of vigilance to health in FHUs; the rethink about the social determinants of health in a wide and articulate way to the services quality, to permanent education, to management in service, to the given attention and to the way how it is installed the popular participation and social control. To the professionals it is presented the great challenge to review their daily practice, their values, behaviors and commitment, which ones must be guided by logical of sharing, work in team, humanescence and alterity, not only by the accomplishment of a professional duty
