| Depuis 1991, des mortalités massives associées à des infections à herpès virus sont rapportées chez des larves et des juvéniles de différentes espèces de bivalves dans différentes régions du globe. Les études ont porté essentiellement sur la mise en évidence de la présence de ce type de virus chez les coquillages d'intérêt économique. Actuellement, l'intérêt se porte sur la persistance du virus dans le milieu marin, et cela dans le but de déterminer si le milieu constitue ou non un moyen de contamination des animaux. Le travail a constitué en une étude sur la persistance de la détection de l'ADN d'herpès virus (OsHV-1) afin de mieux appréhender les modes de dissémination et de transmission du virus. Dans un premier temps, la stabilité de l'ADN purifié et... |

| A simple, rapid, and quantitative bioassay method was compared to a gas chromotography/mass spectrometry (GC/MS) procedure for the analysis of ametryn in surface and groundwater. This method was based on the activity of ametryn in inhibiting the growth of the primary root and shoot of germinating lettuce, Lactuca sativa L. seed. The procedure was sensitive to 0.01 ug/l and was applicable from this concentration up to 0.6 ug/l. Initial surface sterilization of the seed selection of pregerminated seed of certain root lengths, and special equipment are not necessary. So, we concluded that the sensitivity of the bioassay method is compatible with the chromatographic method (GC-MS). However, the study of the correlation between methods suggests that the... |

| The contamination of coastal areas by potentially pathogenic enteric bacteria is of concern for the sustainability of some uses, such as shellfish farming, recreational shellfish harvesting and bathing. The contamination of these environments may occur through the land-spreading of livestock wastes, animal feces deposited on pastures, wastewaters from slaughterhouses or from municipal wastewater treatment plants. The presence of these bacteria in coastal environment may present a potential risk to human health. In fact, shellfish-borne outbreaks or human infections may occur by the consumption of shellfish from contaminated areas or the ingestion of water during bathing in contaminated waters, respectively. To date, few studies focusing on the presence and... |
