Bacteriophage T5

Exploring how bacteriophage T5 takes over host functions and how the viral particle self-assembles in bacteria:
A fundamental research approach for the development of new biotechnological tools


The bacteriophage T5 is a virulent virus that infects the Gram-negative bacteria Escherichia coli. Many original features of T5 make it an attractive model to understand fundamental aspects of host takeover and viral particle assembly. These two lines of research open perspectives to develop new biotechnological tools.
