On the other hand our results suggest that the major MVA deletions contribute to attenuation of this virus, but they cannot explain why high MVA doses are needed to achieve maximum vaccine potency. Annales de l’Institut Pasteur.

The vaccinia virus VACV Lister strain was one of the vaccine strains that enabled smallpox eradication. The influence of deleting region VI was not investigated because it was thought unlikely to affect virulence since it encompasses one gene fragmented in all VACV strains an orthologue of the CPXV virus gene encoding the A-type inclusion protein [ 3 ] as well as a truncated copy of another gene p4c shown to be important for association of viral particles with A-type inclusions 43which are absent from VACV-infected cells 28 Journal Of Invertebrate Pathology64 2 Gerard Andre, Renault Tristan Titration of virus was performed on hamster BHK21 cells, and all of the deletion mutants produced clearly visible plaques after a 2-day incubation period.

Spleens were recovered, and spleen cell suspensions were stimulated with VACV-infected dendritic cells.

Biological characterization of recombinant vaccinia viruses in mice infected by the respiratory route. Survey for neoplasia in Macoma balthica from the Gulf of Gdansk by flow cytometry. The PD 50 s for the mutants were within the same range as that for the parental clone or VACV-Lis, demonstrating that the deletion of up to five selected regions in the VACV Lister virus genome did not alter the ability to efficiently protect mice against a challenge infection.

Ostreid herpesvirus type 1 generalle and host response in adult Pacific oysters, Crassostrea gigas. Mock-infected animals gained weight regularly over the period of observation, whereas animals infected with the VACV isolate or the original VACV Lister strain VACV-Lis gained weight more slowly over the first 2 weeks, then dramatically lost weight until their deaths between day 35 and 44 postinfection Fig.

A portion of the thymidine kinase TK gene was also deleted in a similar manner to isolate a VACV mutant with this gene deleted. The threshold of the titration was Identification of genes from flat oyster Ostrea edulis as suitable housekeeping genes for quantitative real time Beahdry.

Journal of Neuroscience Methods Horizontal lines indicate the mean values for all mice in a group. Genetiuqe mean change in weight as a percentage of the initial weight is plotted against time for one of the experiments as well as the standard deviations for some groups standard deviations not shown were in the same range as those plotted.

In conclusion, our results extend previous findings by demonstrating that considerable virus attenuation may be achieved for immunocompromised animals if multiple regions of the Lister genome are deleted. Experimental transmission of a Herpes-like virus to axenic larvae of Pacific oyster, Crassostrea gigas. Four weeks later the mice were bled and VACV-neutralizing antibodies in the serum of each animal were titrated.
