Abigail A. Salyers has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and materials for introducing DNA into Prevotella ruminicola
    Patent number: 5674733
    Abstract: A method of introducing expressible heterologous DNA into Prevotella ruminicola is provided. The method involves conjugal transfer of a shuttle vector comprising the heterologous DNA operatively linked to a promoter functional in P. ruminicola. The invention also provides shuttle vectors for use in the method and P. ruminicola produced by the method. The invention further provides a tetracycline resistance gene of the TetQ class, or fragments thereof that confer tetracycline resistance, and a protein of the TetQ class that provides resistance to tetracycline by protecting ribosomes from tetracycline, or active fragments thereof. Finally, the invention provides a promoter functional in P. ruminicola and an engineered P. ruminicola comprising expressible foreign DNA.
    Type: Grant

  • DNA probes for identification of bacteroides species
    Patent number: 4977251
    Abstract: DNA hybridization probes have been developed which identify Bacteroides fragilis, members of the Bacteroides fragilis group of species, and members of Bacteroides - Fusobacterium. These probes can be used to detect these obligately anaerobic bacteria in clinical specimens.
