Although little evidence existed to support that view, European countries and in particular France, have regarded echinoderms, including sea urchins, as low risk in terms of feacal contamination. It is hypothesized that the sea urchins mode of feeding, which is based on grazing and differs from bivalve molluscs, would prevent it from concentrating high levels of Escherichia coli. Here, we monitored E. coli levels in sea urchins (Paracentrotus lividus) and in filter-feeder mussels (Mytillus galloprovincialis), collected concurrently from the same natural area over a 1-year period to verify this assumption. Sea urchins were collected on the seafloor, whereas mussels were collected from the water column at a depth of 4 m. Our results showed heavy bacterial... |

Après un rappel des objectifs, du fonctionnement et de la méthode d’interprétation des résultats des réseaux de contrôle microbiologique (REMI) et de surveillance chimique (ROCCH), ce rapport inclut un bilan national et décrit le programme annuel du département du Morbihan. Il présente l’ensemble des résultats obtenus, en particulier l’estimation de la qualité microbiologique et chimique des zones de production de coquillages classées pour la période 2015-2017. En 2017, la surveillance microbiologique des zones de production conchylicole a concerné 51 zones classées. Selon les critères réglementaires pris en compte (règlement CE n°854/2004, modifié par le règlement n°2285/2015), la qualité microbiologique est estimée en « A » pour 23 zones de production,... |

Après un rappel des objectifs, du fonctionnement et de la méthode d’interprétation des résultats du réseau de contrôle microbiologique REMI, ce rapport présente le bilan national et décrit le programme annuel pour le département de la Charente-Maritime. Il présente l’ensemble des résultats obtenus, en particulier l’estimation de la qualité des zones de production de coquillages classées et l’évolution de leur qualité sur la période 2014-2016. Le programme de surveillance 2016 a été réalisé à 99%. Les données manquantes résultent d’un manque de ressource ou de problèmes de disponibilité. Au total, le dispositif d’alerte a été déclenché à 25 reprises en 2016 et a donné lieu à la réalisation de 37 prélèvements et analyses supplémentaires. Toutes les zones de... |

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... |

Marine environment contamination can affect fishing and shellfish farming products (and shellfish in the first place), thus making them improper for human consumption, threatening public health and producer’s business. Analysis and health risk management are mandatory for consumer’s security and shellfish production survival. About microbial risk, monitoring shellfish production areas and several studies carried by LERPC laboratory give a good view of the microbial contamination impacting the Pertuis Charentais shellfish production area. On the other hand, State-Region Plan Contract (CPER) studies results from 2007 to 2013 are presented and discussed; additionally, the law-prescribed sanitary studies for professional on foot-fishing classification are... |

This study investigated the antibacterial activity of propolis produced by A. mellifera and Brazilian stingless bees, called "meliponíneos". Susceptibility tests to ethanolic extracts of propolis (EEP) were performed using bacterial strains (Staphylococcus aureus, Enterococcus sp, and Escherichia coli) isolated from human infections. Dilution of EEP in agar (%v/v) was used for determination of minimal inhibitory concentration (MIC). The stingless bee species (and common names) were: Nannotrigona testaceicornis ("Iraí"), Tetragonisca angustula ("Jataí"), Trigona spinipes ("Arapuá"), Scaptotrigona sp ("Tiúba"), Partamona sp ("Cupira"), Melipona scutellaris ("Uruçu"), Melipona sp ("Manduri"), and Melipona mandaçaia ("Mandaçaia"). EEP inhibitory efficiencies... |
