| ABSTRACT: The plant, Amburana cearensis A. C. Smith (Fabaceae), commonly called cumaru, is widespread in the Caatinga cearense, a less known ecosystem in Brazil. A. cearensis is rich in several compounds like protocatechuic acid, tannins, coumarin, flavonoids and phenolic heterosides, such as amburosides A and B, that have been isolated. The aim of this study was to determine the antimicrobial potential and draw the chemical profile of the distinct characteristics of A. cearensis stem bark decoction, for its possible potential as a food conservation agent. The chemical compounds were characterized by one- and two-dimensional 1H and 13C NMR analyses and Liquid Chromatography-Mass Spectrometry (LCMS). The compounds of coumarin, amburosides A and B, and... |

| Seed deterioration induces the formation of free radicals and proliferation of microorganisms, but the application of external antioxidants may lessen these effects. The aim of this study was to investigate the antioxidant and antimicrobial activity of cathode and anode water on the physiological quality and health of Coffea arabica L. seeds. Part of the seeds were soaked in cathode water and the other part in anode water for periods of 1, 6, 12, 24, and 36 hours. The physiological quality of the seeds was evaluated by the germination test and tetrazolium test, and seed health by the Blotter test. Analysis of variance and Pearson correlation analysis were performed on the data for all the response variables. Soaking in cathode water or anode water up to 24... |

| Numerous studies have shown that subinhibitory concentrations of antimicrobials can alter bacterial virulence factors. This study evaluates motility and biofilm formation by H. pylori 43504 grown in subinhibitory concentrations of amoxicillin (AMX), clarithromycin (CLA), or tetracycline (TET). For the swimming and swarming motility assays, H. pylori 43504 suspensions were prepared with the strain alone or with the strain in AMX, CLA, or TET at ½ MIC. Next, the media were incubated at 37 ºC, under microaerophilia. To assess biofilm formation in the presence of one of the antimicrobials at subinhibitory antimicrobial concentrations, bacterial suspensions (109 CFU/mL) were prepared in 2.5% FBS containing AMX, CLA, or TET at ½ MIC. After incubation for 10... |

| Abstract: Chrysomya megacephala (Diptera: Calliphoridae), known as blowfly, has a great capacity for dispersion and, due to factors such as food abundance and favorable climate, it colonizes Brazil completely in a short time. These insects are important because carrying microorganisms such as bacteria, viruses, protozoa and helminthes, which promote many diseases. The aim of this study was to verify the diversity of bacteria carried by this species in the Federal University of Mato Grosso ? Campus of Sinop during the month of January of 2012. The flies were collected using two traps baited with 100 g of fresh sardines on each and maintained in the field for 24 hours. Twenty specimens of C. megacephala were placed in Petri dishes, to walk for two minutes... |

| ABSTRACT The endophytic bacteria belong to a larger group of microorganisms that have their life-cycle partly or entirely inside the plant and are located in intra and inter-cellular spaces or in the vascular tissue. These bacteria can be found colonizing aerial parts or roots. This review aims to analyze the colonization strategies of endophytic bacteria through interaction with plants, as well as to highlight the metabolic influence of these organisms in plant tissues, which result in physiological and biochemical changes. Depending on the different mechanisms used internally to colonize a plant, these microorganisms are called obligate, facultative, or passive endophytes. Phytostimulation, biofertilization and biological control are mechanisms that... |

| Este estudo teve como objetivo avaliar a frequência de mastite clínica e subclínica e descrever os micro-organismos envolvidos no processo inflamatório da glândula mamária nos rebanhos de búfalos leiteiros no Nordeste do Brasil. Foram analisadas 1.896 amostras de leite provenientes de 474 búfalos em quatro propriedades localizadas nos Estados de Alagoas, Bahia, Ceará e Pernambuco. Após o exame físico da glândula mamária, as amostras de leite de cada teto foram submetidas aos testes da caneca do fundo preto e CMT (California Mastitis Test). As amostras que apresentaram scores ++ e +++ no CMT e as positivas para a caneca do fundo preto foram submetidas ao exame microbiológico. Do total de amostras estudadas, 90/1.896 (4,74%) apresentaram mastite clínica. Com... |
