          Summary

          A cell line, named Epithelioma papulosum cyprini (EPC) and originating from carp epidermal herpes virus-induced hyperplastic lesions, was esta blished and has now given rise to more than 80 subcultures. It grows within a wide temperature range (15–33°C), survives between 7 and 10°C for several months without alterations in its further virus susceptibility and growth characteristics, and degenerates at 37°C. Its karyotype is 2n=96. It propagates most of the systemic infection viruses of the fish families Salmonidae, Cyprinidae, Anguillidae and Esocidae, as well as Indiana-type vesicular stomatitis virus.

          Despite the origin of EPC cells, we were unable to demonstrate the presence of herpes virus in them. Their transformation was reflected in their karyotype (normally 2n=100) and by their growth ability in soft agar medium; monolayer growth, however, was inhibited at a density of 3×10 6 cells/cm 2.

          The temperature growth range, good splitting ratio (1/10) and virus susceptibility make EPC cells a highly suitable material both for fish pathology and for comparative virology studies.

          Résumé

          La séparation enzymatique des cellules d'une lésion cutanée hyperplasique de la carpe induite par un virus de type herpès, a conduit à l'obtention d'une lignée cellulaire épithéliode appelée EPC ( Epithelioma papulosum cyprini) qui a maintenant atteint sa 80è subculture. Cette lignée se développe entre 15 et 33°C, survit sans inconvénients pour son comportement ultérieur entre 7 et 10°C et dégénère rapidement à 37°C. A 30°C, l'ensemencement de 3×10 5 cellules/cm 2 dans du milieu de Stoker, additionné de 10% de phosphate de tryptose et de 10% de sérum d'embryon de bovin, est suivi d'un décuplement du nombre initial des cellules en 6 à 7 jours, qui conduit à la densité de saturation. Le nombre moyen de chromosomes est de 96 au lieu de 100 dans les cellules primaires de carpe, et leur transformation leur permet de se développer en suspension dans un milieu gélifié. Le virus herpétique présent dans la lésion d'origine n'a jamais pu être retrouvé au cours des contrôles effectués, et l'infection locale qu'il induit chez son hôte est d'ailleurs bénigne.

          Les cellules EPC sont sensibles à tous les rhabdovirus de poissons d'eau douce actuellement décrits ainsi qu'à deux des sérotypes du virus de la nécrose pancréatique infectieuse (Sp et VR299) et au virus de la stomatite vésiculeuse de type Indiana.

          Leur large plage thermique de croissance et leur sensibilité à de nombreux virus en font un matériel de choix en pathologie virale des poissons comme en virologie comparée.
