13. Strutural characterization of hypothetical proteins complex - XACb0032/XACb0033 from Xanthomonas axonopodis pv. citri / Caracterização estrutural do complexo de proteinas hipoteticas - XACb0032/XACb0033 da bacteria Xanthomonas axonopodis pv. citri
Xanthomonas axonopodis pv. citri (Xac) is the causative agent of citrus canker, a disease of significant economic importance worldwide. The molecular bases of the virulence mechanism are still unknown, but is believed that transfer of bacterial virulence proteins directly into the host cell cytoplasm is mediated by protein secretion systems, mainly type III

14. Avaliação do potencial de agentes biológicos e seus produtos no controle da cancro cítrico causado por Xanthomonas axonopodis pv. citri
Asiatic citrus canker caused by Xanthomonas axonopodis pv. citri (Xac) (Hasse) is a disease known worldwide in the majority of commercial citrus production areas Limited strategies exist for suppression of citrus canker on more susceptible cultivars. The application of microorganisms as agent to control citrus canker is a great ecological progress to solve t

15. 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

16. In silico identification of potential chaperone genes that belong to type III and type IV secretion systems in Xanthomonas axonopodis pv citri
The secretion of bacterial virulence factors and flagellar components requires the assistance of specific type III and flagellar chaperones. Standard computational annotation of the genome of Xanthomonas axonopodis pv citri, a plant pathogen that causes citrus canker, initially did not identify any genes belonging to these chaperone categories since the prim

17. Fisiologia de Bacillus subtilis R14 sob condiÃÃes restrita e irrestrita de oxigÃnio: produÃÃo de compostos bioativos e esporulaÃÃo
Several strains of Bacillus subtilis produce lipopeptides, which are amphiphilic compounds with surfactant and antimicrobial activities. Production of lipopeptide, sporulation and competence in B. subtilis are interconnected through a complex array of controlling elements. The aims of this study were to evaluate the activity of B. subtilis R14 against severa

18. Genetic transformation of citrus with bacterio-opsin (bo), cecropin and gus genes. / Transformação genética de citros com os genes bacteriopsina (bO), cecropina e gus.
Application of modern biotechnology techniques, as genetic transformation, has helped breeding programs of perennial plant species. This technique is already successfully used in citrus in several countries, mostly to the production of more disease-tolerant plants. Present work had three objectives as it follows: 1. genetic transformation of Rangpur lime roo

19. Avaliação de agentes biológicos e seus produtos na incidência de lesões foliares do cancro cítrico
O cancro cítrico, causado por Xanthomonas axonopodis pv. citri (Xac), é um grave problema para a citricultura, pois o principal método de controle é a erradicação das plantas contaminadas. O controle biológico com microrganismos representa uma alternativa no controle da doença. Foram obtidos quatro isolados bacterianos, de lesões de cancro cítrico

20. Cancro bacteriano do tomateiro: metodologia de inoculação, reação de genótipos do hospedeiro e eficiência de químicos sobre o controle. / Bacterial canker of tomato: inoculation methodology, reaction of host genotypes and efficiency of chemicals on the control.
O cancro bacteriano, causado por Clavibacter michiganensis subsp. michiganensis (Cmm), é uma das doenças mais importantes da cultura do tomate (Lycopersicon esculentum Mill.), especialmente para tomateiros estaqueados. O controle está fundamentado na adoção de um conjunto de medidas preventivas, pois poucas são as informações sobre materiais resisten

21. Quantitative PCR Method for Diagnosis of Citrus Bacterial Canker†
For diagnosis of citrus bacterial canker by PCR, an internal standard is employed to ensure the quality of the DNA extraction and that proper requisites exist for the amplification reaction. The ratio of PCR products from the internal standard and bacterial target is used to estimate the initial bacterial concentration in citrus tissues with lesions.

22. Diagnosis of ear canker in dogs by bacterial-colony displacement.
The diagnosis of a case of ear canker in a dog by bacterial-colony displacement is described. In this case, the causative mite was detected on the primary plates inoculated from a bacterial swab. This result indicates that the phenomenon of bacterial-colony displacement should be noted and investigated in diagnostic laboratories, as it indicates the presence

23. Evaluation of the Biolog Substrate Utilization System To Identify and Assess Metabolic Variation among Strains of Xanthomonas campestris pv. Citri
Metabolic fingerprints of 148 strains of Xanthomonas campestris pv. citri originating from 24 countries and associated with various forms of citrus bacterial canker disease (CBCD) were obtained by using the Biolog substrate utilization system. Metabolic profiles were used to attempt strain identification. Only 6.8% of the studied strains were correctly ident

24. Genomic Relatedness of Xanthomonas campestris Strains Causing Diseases of Citrus †
Xanthomonas campestris strains that cause disease in citrus were compared by restriction endonuclease analysis of DNA fragments separated by pulsed-field gel electrophoresis and by DNA reassociation. Strains of X. campestris pv. citrumelo, which cause citrus bacterial spot, were, on average, 88% related to each other by DNA reassociation, although these stra
