Rotaviruses have been implicated as the major causal agents of acute diarrhoea in mammals and fowls. Experimental rotavirus infection have been associated to a series of sub-cellular pathologic alterations leading to cell lysis which may represent key functions in the pathogenesis of the diarrhoeic disease. The current work describes the cytopathic changes in cultured MA-104 cells infected by a simian (SA-11) and a porcine (1154) rotavirus strains. Trypan blue exclusion staining showed increased cell permeability after infection by both strains, as demonstrated by cell viability. This effect was confirmed by the leakage of infected cells evaluated by chromium release. Nuclear fragmentation was observed by acridine orange and Wright staining but specific DNA cleavage was not detected. Ultrastructural changes, such as chromatin condensation, cytoplasm vacuolisation, and loss of intercellular contact were shown in infected cells for both strains. In situ terminal deoxynucleotidyl transferase (Tunel) assay did not show positive result. In conclusion, we demonstrated that both strains of rotavirus induced necrosis as the major degenerative effect.

(résumé de l'ouvrage) Studies on Origen at the beginning of the 21st century continue to dig old and new grounds of research. After the epoch-making rediscovery of the great Alexandrian doctor throughout the past century, contemporary research increasingly deals with the close context of his writings and thought: the cultural tradition of Alexandria in all its components - Hellenistic, Jewish, Egyptian, Gnostic and Christian. This topic was the theme chosen for the «Colloquium Origenianum Octavum» (Pisa, 27-31 August 2001), a major event of patristic scholarship. The proceedings now contain more than 100 papers of contributors from about 30 countries. They not only provide the best overview on a lively field of studies but also demonstrate how Origen's heritage in Christian history and theology carried with it the imprint of one of the most vital traditions of Western civilization.

Comment, dans les premiers siècles de l'histoire du christianisme, se sont formés les livres du Nouveau Testament ? Une dizaine de spécialistes européens et américains abordent ce problème majeur avec un double souci : présenter au public francophone un état de la recherche et faire progresser les études par le recours à l'histoire sociale et à l'histoire des controverses. Une attention particulière est portée à des sources habituellement négligées parce qu'elles sont d'un accès difficile| il s'agit en particulier de textes orientaux (coptes, syriaques, arméniens) qui montrent que le Nouveau Testament est loin de s'être constitué de manière strictement uniforme au cours des cinq premiers siècles.
