  • Patent number: 10046038
    Abstract: The antigenic mass of Leptospira cultures can be significantly increased, independent from any increase in biomass, by supplementing Leptospira cultures with a specific type of fatty acid: a polyunsaturated C18 fatty acid. This provides advantages in the production Leptospira antigens. Also this enables the production of improved Leptospirosis vaccines, that are safer and more effective.
    Type: Grant

  • Publication number: 20140178433
    Abstract: The antigenic mass of Leptospira cultures can be significantly increased, independent from any increase in biomass, by supplementing Leptospira cultures with a specific fatty acid: linoleic acid. This provides advantages in the production Leptospira antigens. Also this enables the production of improved Leptospirosis vaccines, that are safer and more effective.

  • Patent number: 8586331
    Abstract: The present invention pertains to a method to produce RTX-toxin Apxl by culturing Actinobacillus pleuropneumoniae bacteria in a liquid culturing medium that supports growth of the bacteria, to which medium a calcium salt is added to form calcium ions in the medium, wherein the culturing medium contains borogluconate to form a calcium borogluconate complex in the medium.

  • Patent number: 8445235
    Abstract: The current invention pertains to a method to produce RTX-toxins ApxI or ApxIII by culturing Actinobacillus pleuropneumoniae bacteria in a liquid culturing medium that supports growth of the bacteria, characterized in that air is passed through the medium, wherein the air has a carbon dioxide content above normal atmospheric level to increase RTX-toxin production during the production phase of the RTX-toxins.
