13. Metatranscriptomic analysis of small RNAs present in soybean deep sequencing libraries
A large number of small RNAs unrelated to the soybean genome were identified after deep sequencing of soybean small RNA libraries. A metatranscriptomic analysis was carried out to identify the origin of these sequences. Comparative analyses of small interference RNAs (siRNAs) present in samples collected in open areas corresponding to soybean field plantatio

15. Mecanismos envolvidos com a sobrevivência de Xylella fastidiosa em condições de estresse e efeito de N-Acetil-L-Cisteína em seu biofilme / Mechanisms involved in Xylella fastidiosa survival under stress conditions and effect of N-Acetyl-L-Cysteine on its biofilm
Xylella fastidiosa is a Gram-negative bacterium that causes several diseases in different plant species, including citrus variegated chlorosis (CVC) in sweet orange (Citrus sinensis L. Osbeck), whose economic damage is of millions of dollars annually. The symptoms development has been associated with the blockage of xylem vessels caused by bacterial biofilm

16. Probiosis: concepts and prospects
The use of probiotics in animal and human feeding has been a subject of increasing interest both for the academia and the industry, mostly due to their potential positive effects on health and profitability. However, the knowledge on the composition of bacterial gastrointestinal communities in humans and animals, as well as its respective nutritional require

17. Molecular battles between plant and pathogenic bacteria in the phyllosphere
The phyllosphere, i.e., the aerial parts of the plant, provides one of the most important niches for microbial colonization. This niche supports the survival and, often, proliferation of microbes such as fungi and bacteria with diverse lifestyles including epiphytes, saprophytes, and pathogens. Although most microbes may complete the life cycle on the leaf s

18. Recent research data on the removal of pharmaceuticals from sewage treatment plants (STP)
Pharmaceutical compounds have been detected in sewage treatment plant (STP) effluents, surface waters and, less frequently, in groundwater and drinking water, all over the world. Different sources are responsible for their appearance in the aquatic environment, however, it is widely accepted that the main sources of this type of pollutant are STP effluents.

19. Polyetic progress and quantification of damages caused by Citrus Variegated Chlorosis in Natal Orange trees submitted to water deficits / Progresso poliético e quantificação de danos da Clorose Variegada dos Citros em laranjeiras Natalsubmetidas a déficits hídricos
A Clorose Variegada dos Citros (CVC), causada pela bactéria Xylella fastidiosa, é atualmente a doença de maior incidência no Estado de São Paulo. A incidência e a severidade da doença são maiores nas regiões Norte e Noroeste do Estado, onde o clima é predominantemente quente e com déficit hídrico, principalmente no inverno. Embora não haja nada

20. A comparative evaluation of antibacterial potential of some plants used in indian traditional medicine for the treatment of microbial infections
A comparative in vitro antibacterial potential of extracts (aqueous and ethanol) of five important medicinal plants (Aegle marmelos, Azadirachta indica, Terminalia chebula, Mangifera indica and Ocimum sanctum) were investigated using microbial growth inhibition assays against the common human pathogenic bacteria (Staphylococcus aureus, Pseudomonas aeruginosa

22. Development of a database for classification and analysis of type IV secretion systems / Desenvolvimento de um banco de dados para classificação e análise de sistemas de secreção do tipo IV bacteriano
The type IV secretion system can be classified as a large family of macromolecule transporters divided in three recognized sub-families involved in different bacterial functions. The major sub-family of T4SS is the conjugation system, which allows transfer of genetic material as a nucleoprotein via cell contact among bacteria. Analogously to bacterial conjug

23. Antimicrobial activity of wax and hexane extracts from Citrus spp. peels
Antibacterial and antifungal properties of wax and hexane extracts of Citrus spp. peels were tested using bioautographic and microdilution techniques against three plant pathogenic fungi (Penicillium digitatum, Curvularia sp., and Colletotrichum sp.), two human pathogens (Trichophyton mentagrophytes and Microsporum canis), and two opportunistic bacteria (Esc

24. Gene Expression in Xanthomonas axonopodis pv. citri Mediated by Plant Inducible Promoter (PIP-box) / "Expressão gênica em Xanthomonas axonopodis pv. citri controlada por promotores induzidos pela planta hospedeira"
The citrus canker, caused by the bacterial pathogen Xanthomonas axonopodis pv citri (Xac), is considered worldwide as one of the most important disease of citrus crop due to the lack of resistance in citrus plants and to the absence of efficient methods to control the disease. It was already shown that several genes involved in virulence and pathogenicity in
