  • Culture medium for type B
    Patent number: 8673617
    Abstract: The invention relates to a culture medium for Haemophilus influenzae type b, characterized in that the source of protein nitrogen is of non-animal origin and comprises at least one plant peptone and in that the heme source consists of protoporphyrin IX. This medium serves in particular for the production of polyribosyl phosphate (PRP) and for the manufacture of a vaccine against Haemophilus influenzae type b meningitis.
    Type: Grant
    Filed: July 10, 2008
    Date of Patent: March 18, 2014
    Assignee: Sanofi Pasteur SA

  • Self-Replicating Vector Lacking An Antibiotic-Resistance Gene
    Publication number: 20110207173
    Abstract: The subject matter of the present invention is a novel vector and the use thereof for producing a heterologous protein or a gene of interest, that can be used, for example, in the context of an immunization or gene therapy programme and concerns in particular a self-replicating vector lacking an antibiotic-resistance gene, comprising a sequence encoding the ccdA protein functionally linked to a first promoter, the sequence of the Cer locus and a heterologous sequence, functionally linked to a second promoter.
