Nativa da Região Amazônica, a castanheira (Bertholletia excelsa H.B.K.) é considerada uma das maiores riquezas nos estados que formam a Amazônia Brasileira. Um dos grandes problemas na conservação da castanha-do-brasil deve-se ao crescimento de fungos produtores de aflatoxinas e bactérias patogênicas, por causa das condições de umidade relativa e temperatura elevadas a que é submetida desde o momento da queda do ouriço. Assim, buscou-se identificar, em indústrias de processamento de castanha-do-brasil no Acre, os microrganismos responsáveis pela qualidade sanitária, especialmente os do grupo coliformes, bactérias mesáfilas, bolores e leveduras. Foram coletadas amostras nos meses de agosto de 2001 a maio de 2002, em cinco etapas do processamento. As... |

The principle of this method is to evaluate, by counts exercised upon selective media, the relative importance of the different bacteria families in the flora of the coastal waters. It is important to separate the contaminant species and the commensal species in the marine environment. Ten culture media distributed into four categories (selective, non selective, saline and non saline) were examined by numeration. Counts were transferred on a diagram allowing to plot down a profile of bacterial flora of water sampled from a given geographical area. The profiles are arranged by a classification method. The sampling points with similar or adjoining profiles were assembled and marked on the chart. In this way, the authors obtained areas representing the impact... |

Pour contrôler la prolifération de la végétation aquatique flottante, en Côte d'Ivoire, une ouverture dans le cordon littoral a été pratiquée en septembre 1987 mettant ainsi en communication directe le fleuve Comoé avec l'océan. L'impact de cet aménagement sur l'hydrochimie (salinité, éléments nutritifs et biomasse chlorophyllienne)et le degré de contamination bactérienne a été étudié dans la zone proche du canal de Vridi. Avant la réouverture du grau de Bassam, les eaux du Comoé s'évacuaient dans l'océan par ce canal artificiel situé dans la ville d'Abidjan. L'étude comparative de deux cycles annuels en quatre stations avant (1985) et après (1987/88)l'ouverture du grau de Bassam (Analyses en Composantes Principales(ACP))est discutée en fonction des... |

Trois campagnes sur l'ensemble de la zone urbaine de la lagune Ebrié (Abidjan, Côte d'Ivoire)ont été réalisées à trois saisons caractéristiques de l'hydroclimat lagunaire (grande saison sèche, grande saison des pluies, petite saison des pluies et crue fluviale)pour estimer les niveaux de pollution organique (seston, ions, ammonium et orthophosphates) et bactérienne ( E.coli et C.perfringens) des eaux à proximité des berges.Celles-ci présentent une forte eutrophisation caractérisée par des concentrations en permanence très élevées pour N-NH4 et lors de la grande saison sèche pour P-PO4. Les charges minérales solides s'accroissent en période de forte dessalure et plus particulièrement lors de la grande saison des pluies.A l'opposé, les charges organiques... |

Poultry meat can be contaminated with a variety of microorganisms, including those capable of spoiling the product during chill storage, and certain foodborne pathogens. Human illness may follow from handling of raw meat, undercooking or mishandling of the cooked product. While Salmonella and Campylobacter spp. remain the organisms of greatest global concern in this respect, others present include the more recently reported Arcobacter and Helicobacter spp. and, occasionally, verotoxigenic Escherichia coli. Also considered here is the growing problem of antimicrobial resistance among poultry-associated pathogens. Because of the need for a systematic and universally applicable approach to food safety control, the Hazard Analysis Critical Control Point... |

Seven fungi were isolated from 50 samples of cosmetic powders. Morphological analyses and ribosomal DNA Internal Transcribed Spacers sequencing were performed which allowed the discrimination of the isolated fungi as Aspergillus fumigatus, Penicillium sp., and Cladosporium sp. which could have, among their species, potentially pathogenic microorganisms. |
