| Bokashi is fermented organic compost capable of improving the physical, chemical, and biological conditions of the soils. The compost action in the agricultural production system is influenced by its preparation, resulting in products with different physicochemical characteristics. The study aimed to characterize bokashi produced on-farm and compare it with commercial products. The produced composts in southern Brazil were obtained through efficient microorganisms (EM), collected in an area of permanent preservation, and kefir. Two commercial composts were used for comparison (Plantae FertTM and Bokashi Sementes BrasilTM). Physical characteristics related to apparent specific gravity, water content, and water retention capacity and chemical characteristics... |

| Protozoa population, microbial synthesis efficiency and rumen degradability of dry matter and neutral detergent fiber in cattle fed on diets with different lipid rates were evaluated. Nine 16-month-old Nelore young bulls, cannulated in the rumen and duodenum, weighing 232 ± 35 kg, were used in the trial. Experimental design consisted of a 3 x 3 square in triplicate, comprising the following treatments: 2, 4 and 6% lipid in diet. In situ degradability was assessed by rumen incubation of corn silage, soybean, soybean meal and citrus pulp during 0, 3, 6, 12, 24, 48, 72 and 96h. The flow of microbial nitrogen and microbial efficiency were not influenced (p > 0.05) by the inclusion of lipid levels in the diet. When the animals received diet with 4%... |

| Estudou-se o efeito da adição de enzimas fibrolíticas (celulase e xilanase) sobre a degradabilidade in situ da matéria seca (MS), proteína bruta (PB), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA) e hemicelulose da silagem de milho (SM) e da palha de arroz (PA), utilizando seis bovinos fistulados no rúmen. Também foi avaliada a proporção de nitrogênio (N) insolúvel em detergente ácido em relação ao N total (NIDA/N total). As enzimas fibrolíticas foram extraídas dos fungos Aspergillus Níger e Trichoderma longibrachiatum, sendo fornecido 0,75 g kg-1 de MS animal-1 dia-1, via cânula ruminal. Os tempos de incubação foram: 0, 3, 6, 12, 24, 48, 72 e 96 h. Os resíduos de incubação foram comparados por meio da microscopia eletrônica de... |

| ABSTRACT Four soybean meal-based diets containing increasing levels of an enzyme complex (E50, E100, E150 and E200 at 50, 100, 150 and 200 g ton-1, respectively) and one soybean meal-based diet without the enzyme complex (E0) were fed in triplicate to M. liza juveniles in a semi-static flow system with 20 fish per tank for 75 days. There were no differences between the treatments for animal performance parameters, but fish fed the enzyme complex treatment exhibited significantly (P<0.05) higher values of calcium bone retention compared with control fish. Although there was no relationship between bacterial counts in different sections of the gastrointestinal tract or enzyme levels, filamentous bacteria were increased in E50 compared with E150. All of... |

| 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... |

| The aim of this study was to evaluate somatic cell count (SCC), prevalence and etiology of mastitis in a dairy buffalo herd from Analândia, São Paulo State, Brazil, in the dry and rainy seasons. Additionally, antimicrobial susceptibility profile of microorganisms isolated from milk samples was also evaluated. 1,042 milk samples from female Murrah buffaloes in a dairy farm located in Analândia, São Paulo State, Brazil, collected between May 2011 and November 2012 were analyzed. After the mammary gland physical examination, strip cup test and California Mastitis Test (CMT) were performed. Afterwards, 50mL of milk samples from each mammary quarter were collected aseptically for SCC in automatic equipment and microbiological examination. The antimicrobial... |

| The aim of this work was to study the constructed wetland system for the treatment of water from the Corumbataí river simulated on a laboratory scale. The parameters analyzed at different points of the system were ammonia, biochemical demand for oxygen (BDO), chemical demand for oxygen (CDO), chlorides, apparent color, conductivity, dissolved oxygen, magnesium (Mg), sodium (Na), potassium (K), silicon (Si), total phosphorous, total coliforms and Escherichia coli, total dissolved solids (TDS), turbidity, and macrophyte biomass. The results demonstrated that this alternative water treatment system was effective in removing the microorganisms (total coliforms and E. coli), among other parameters analyzed, for varying periods of the treatment, promoting... |

| Total phosphorus concentration was used to define the trophic state of the main sub-basins of the middle Rio Doce, in Minas Gerais State (southeast Brazil) and physical, chemical, and microbiological variables of water were analyzed during 2000 to 2001. The study evaluated changes in water quality caused by seasonality and human activities. Water temperature, conductivity, pH, total alkalinity, dissolved oxygen, and concentrations of NH4-N, NO2-N, NO3-N, total-N, PO4-P, total-P, DOC, and chlorophyll-a were measured in seven rivers stretches (sampling stations). Total yeasts, faecal and total coliforms, and heterotrophic bacteria were also determined. The studied areas were considered to be under oligotrophic to eutrophic conditions. The variables that... |

| 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... |

| Processes like ultrasound, chlorination and filtration-adsorption were compared to eliminate microorganisms and to adjust established parameters of public drinking water. A mini water treatment plant (WTP-CB), in pilot scale, was projected and built to evaluate each process influence as: decontamination, coagulation-flocculation, sedimentation and filtration. Total and fecal coliforms, Escherichia coli and heterotrophic bacteria and physic/chemical parameters were quantified from water. Ultrasound, chlorination and filtration-adsorption were efficient to inactivate and/or eliminate bacteria. Ultrasound decontamination in addition to coagulation-flocculation, sedimentation and filtration, could be considered as an alternative treatment water solution where... |

| Nosocomial pneumonia is a common complication in patients on mechanical ventilation and results in significant mortality. Diagnosis of pneumonia in patients who are intubated and under mechanical ventilation is difficult, even with the aid of clinical, laboratorial, and endoscopic tests. The objective of this study was to compare three methods of tracheal sputum collection in patients with a clinical and radiological diagnosis of pneumonia. Twenty-two patients with a clinical diagnosis of liver disease were enrolled, 18 years of age or older, 13 males and nine females, who had been mechanically ventilated over an intubation period of 5.86 ± 4.62 days. These patients were being treated in intensive care unit (ICU) of the Liver Transplantdepartment.... |
