| The purpose of this paper was to study the storage of the residue from the extraction of cassava starch without the use of storage technologies, through chemical evaluation, pH values, temperature, development of microorganisms and mycotoxins. A randomized block design was used with eight treatments (different storage periods: 0, 3, 6, 9, 12, 15, 18 and 21 days) and five replications. There was a significant difference for DM content, as a function of days in storage. The chemical composition of the residue from the extraction of cassava starch did not changed throughout the storage period. A negative linear effect was obtained for the pH values, which decreased with days in storage. There was significance of the storage period only for the fungus and... |

| Ants inhabit several types of natural and urban habitats, where they successfully nest. In urban environments, the hospitals should be considered priority for studies, as ants pose risks to human health due to their pathogen carrying potential. We aimed at surveying the literature about studies on ants in hospital settings in Brazil in the past 20 years. We found 40 papers in 22 journals, the first one published in 1993. Among them, 26 papers assessed pathogenic microorganisms on ants. We recorded 59 ant species, being Tapinoma melanocephalumthe most common. The Minas Gerais and São Paulo states had the largest number of published papers. Mato Grosso do Sul and Rio Grande do Sul showed the highest number of species. Exotic ant species were recorded in all... |

| Mastitis is an inflammation of the mammary gland that causes severe economic losses due to reduced milk production, expence on pharmaceuticals, veterinary care, discarding of milk after treatment and discarding of affected animals. This inflammatory process may have distinct origins, but all cases of economic importance are caused by microorganisms. According to their origin and means of transmission, the main etiological agents were put together in two groups, contagious microorganisms (Streptococcus agalactiae, Staphylococcus sp, e Corynebacterium bovis) transmitted mainly during rnilking and environmental microorganisms (Streptococcus uberis, Enterobacteriaceae, fungos, algae of the genus Prototheca, etc.).Clinical mastitis is characterized by visible... |

| 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... |

| 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... |

| Durante la estación lluviosa (marzo 2011), las especies identificadas de la microfauna bentónica en el área de la bahía de Manta son: Bulimina pulchella, Buliminella elegantissima, Cibicides bertheloti, F. boueana, Nonion pizarrense, Quinqueloculina lamarckiana, Rotalia beccarii, Lagena striata y la única especie de la microflora béntica fue Coscinodiscus perforatus y corresponden a la provincia zoogeográfica panameña propuesta por Boltovskoy (1965) y confirmada por Boltosvskoy y Gualancañay (1975) y Gualancañay (1986). Durante la fase seca (septiembre 2011), la microflora béntica estuvo representada por dos especies de diatomeas bénticas: Cocinodiscus perforatus y Polymixus coronalis. En cambio la microfauna bentónica se la halló distribuida en el área de... |
