13. Closely-related Xanthomonas citri subsp. citri isolates trigger distinct histological and transcriptional responses in Citrus limon
ABSTRACT Citrus canker, caused by Xanthomonas citri subsp. citri (Xcc), has an important economic impact on the citrus industry. Extensive information is available about the disease but, nevertheless, the study of plant-pathogen interactions could provide new information in the understanding of citrus canker disease. A new isolate has been identified, Xcc AT

14. Highly Solvent Tolerance in Serratia marcescens IBBPo15
ABSTRACT The aim of this study was to investigate the solvent tolerance mechanisms in Serratia marcescens strain IBBPo15 (KT315653). Serratia marcescens IBBPo15 exhibited remarkable solvent-tolerance, being able to survive in the presence of high concentrations (above 40%) of toxic organic solvents, such as cyclohexane, n-hexane, n-decane, toluene, styrene,

15. Polyphasic analysis of Acidovorax citrulli strains from northeastern Brazil
ABSTRACT Bacterial fruit blotch (BFB) of cucurbit plants is caused by Acidovorax citrulli and represents a serious concern to melon (Cucumis melo L.) growers worldwide, including those in Brazil. Thirty-four A. citrulli strains from different melon production areas of northeastern Brazil were characterized for their virulence on melon fruits and their substr

16. The genotypic diversity and lipase production of some thermophilic bacilli from different genera
Abstract Thermophilic 32 isolates and 20 reference bacilli were subjected to Rep-PCR and ITS-PCR fingerprinting for determination of their genotypic diversity, before screening lipase activities. By these methods, all the isolates and references could easily be differentiated up to subspecies level from each other. In screening assay, 11 isolates and 7 refer

18. Molecular characterization of multidrug-resistant
Klebsiella pneumoniae isolatesKlebsiella pneumoniae is an important cause of healthcare-associated infections worldwide. Selective pressure, the extensive use of antibiotics, and the conjugational transmission of antibiotic resistance genes across bacterial species and genera facilitate the emergence of multidrug-resistant (MDR)K. pneumoniae .

19. Comparing Acidovorax citrulli strains from melon and watermelon: Phenotypic characteristics, pathogenicity and genetic diversity
Melon and watermelon bacterial fruit blotch, incited by Acidovorax citrulli, is limited to some areas in Brazil but causes important losses, mainly in melon-producing regions. Although genetic diversity has been observed among strains belonging to the species, they are considered a homogeneous group based on the fact that they show only slight physiological

20. Caracterização de bactérias promotoras de crescimento vegetal em Vriesea gigantea Gaud. e Tillandsia aeranthos (Loiseleur) L.B. Smith (Bromeliaceae)
Microrganismos que habitam o interior e a superfície podem fornecer substancias essenciais ao crescimento das plantas, como fitormônios e nutrientes essenciais. O presente trabalho teve como objetivo isolar e caracterizar as bactérias da filosfera, do ambiente endofítico e a água de tanque associadas à Vriesea gigantea e Tillandsia aeranthos. As bacté

21. Molecular identification of Lactobacillus spp. associated with puba, a Brazilian fermented cassava food
Puba or carimã is a Brazilian staple food obtained by spontaneous submerged fermentation of cassava roots. A total of 116 lactobacilli and three cocci isolates from 20 commercial puba samples were recovered on de Man, Rogosa and Sharpe agar (MRS); they were characterized for their antagonistic activity against foodborne pathogens and identified taxonomicall

22. Construction of yellow fever virus subgenomic replicons by yeast-based homologous recombination cloning technique
O replicon de RNA derivado do genoma de Flavivirus é uma ferramenta valiosa para o estudo de replicação viral independente da montagem e da maturação do virion, além de possuir um grande potencial para expressão de genes heterólogos. Neste estudo nós descrevemos a construção de replicons subgenômicos do vírus da febre amarela utilizando a técni

23. Genotipificação de isolados de Staphylococcus epidermidis provenientes de casos de mastite caprina
Para verificar a dinâmica da resistência aos antimicrobianos em uma propriedade rural no município de Santa Maria da Boa Vista, PE, foram avaliados 14 isolados de Staphylococcus epidermidis de caprinos com mastite subclínica. O perfil de resistência aos antimicrobianos foi determinado pelo teste de difusão em disco. A genotipificação foi realizada em

24. Endophytic bacterial diversity in banana 'Prata Anã' (Musa spp.) roots
The genetic diversity of endophytic bacteria in banana 'Prata Anã' roots was characterized. Two hundred and one endophytic bacteria were isolated, 151 of which were classified as Gram-positive and 50 as Gram-negative. No hypersensitivity response was observed in any of the isolates. The rep-PCR technique generated different molecular profiles for each prime
