| Les rotavirus font partie des principaux virus entériques humains susceptibles d'être rencontrés dans l'environnement. Leur mise en évidence par culture cellulaire dans des prélèvements est longue et peu sensible, ce qui explique le manque de données sur la contamination du littoral. La RT-seminested PCR a été développée pour pallier ces inconvénients. Après une mise au point méthodologique cette technique a été utilisée lors d'études in vitro et in situ. Les études in vitro sur le devenir des rotavirus en eau de mer, suivi par RT-PCR quantitative et par multiplication en culture cellulaire, montrent que dans des conditions proches de celles du milieu naturel (eau de mer non stérile et à une température relativement basse), la détection d'ARN viral peut... |

| The main pathogenic enteric viruses able to persist in the environment, such as hepatitis A virus (HAV), Norwalk-like virus (NLV), enterovirus (EV), rotavirus (RV), and astrovirus (AV), were detected by reverse transcription-PCR and hybridization in shellfish during a 3-year study. Oyster samples (n = 108), occasionally containing bacteria, were less frequently contaminated, showing positivity for AV (17%), NLV (23%), EV (19%), and RV (27%), whereas mussel samples, collected in areas routinely impacted by human sewage, were more highly contaminated: AV (50%), HAV (13%), NLV (35%), EV (45%), and RV (52%). Sequences obtained from HAV and NLV amplicons shelved a great variety of strains, especially for NLV (strains close to Mexico, Snow Mountain Agent, or... |

| Oysters harvested in western France, from five sites associated with outbreaks of food-borne norovirus gastroenteritis between February 2000 and March 2001, were assayed for enterovirus RNA by reverse transcriptase-heminested polymerase chain reaction (RT-heminested PCR). Forty percent (21/52) of shellfish samples (pool of seven oysters) were contaminated by enteroviruses. Infectious coxsackieviruses serotype A21 were isolated from three of these positive samples. Amplicons corresponding to 65 base sequences in the 5' untranslated region of the enteroviral genome were analyzed by direct sequencing. Interpretable results were obtained from 18 amplicons, but mixtures of sequences confused the results from 3 samples. Sequences isolated from samples from the... |
