| Afin d'améliorer les numérations bactériennes du sédiment, nous avons testé différentes méthodes physiques et chimiques pour relarguer les bactéries des particules. Une étude préliminaire a permis de définir des concentrations et des temps d'action non toxiques pour des bactéries d'intérêt sanitaire. Les différentes techniques testées ne permettent d'augmenter la numération, dans le meilleur des cas (action du lauryl sulfate de sodium), que d'une demi unité log. |

| Seismic, Seabeam, magnetic and gravimetrie surveys in the southern part of the N-Fiji basin were conducted during the SEAPSO LEG III Cruise. The active spreading axis was recognized between 17°30'S and 21°S. It consists of a continuous N-S Ridge cross-cut by transverse directions oriented N25 and N45. North of 17°30'S, the spreading System is more complex due to the existence of a possible triple junction located around 15° S. The eastern part of the N-Fiji basin, west of Viti Levu is mostly characterized by alternating highs and deeps (<4,000 m). This area must be regarded no more as a spreading center, but as complex boundary suffering transverse tectonics. |

| Microbes regularly contaminate Thau lagoon shellfish. Between 1997 and 2007, 18% of the analyses carried out in dry weather recorded more than 230 Escherichia coli / 100 g of bivalves (Ifremer French microbial monitoring network), leading the administration to restrict the shellfish harvest area, including suspension of production. This study aims to determine, the contribution of seabirds, which roost at night on the Thau lagoon shellfish growing frames, to shellfish faecal pollution in dry weather.Data were collected in 2008 from both the drainage area (pollution input) and the lagoon (water quality and microbial monitoring, seabird counts) in dry weather. The data showed that, with no watershed input or lagoon resurgence, microbial contaminants were... |

| 129 strains of Micrococcaceae were isolated from food of animal origin (minced meat, cakes with confectioner's custard) on Baird-Parker medium. 120 were Staphylococcus and 9 Micrococcus, according to the ID 32 STAPH-System (1989). The results were analyzed using a computer program. 60% of these 120 Staphylococcus strains of animal origin were coagulase positive S. aureus (aurease+, Rapidec Staph technique). 46% were resistant to novobiocin (5 microg/ml), 13 to 44% were identified with negative discordant tests using this micromethod. 44% produced no acetoin, 35% had no urease and 15% no arginine dihydrolase. 48 Staphylococcus strains (40%) were identified as human coagulase negative Staphylococcus species (strains: 39; species: 9) or as animal species... |
