    摘要: Vaccines for conferring immunity in mammals to infective pathogens are provided, as well as vectors and methods for plastid transformation of plants to produce protective antigens and vaccines for oral delivery. The invention further provides transformed plastids having the ability to survive selection in both the light and the dark, at different developmental stages by using genes coding for two different enzymes capable of detoxifying the same selectable marker, driven by regulatory signals that are functional in proplastids as well as in mature chloroplasts. The invention utilizes antibiotic-free selectable markers to provide edible vaccines for conferring immunity to a mammal against Bacillus anthracis, as well as Yersina pestis. The vaccines are operative by parenteral administration as well. The invention also extends to the transformed plants, plant parts, and seeds and progeny thereof. The invention is applicable to monocot and dicot plants.

    摘要: A novel technique for improving the production by bacteria of amino acids that contain sulfur has been developed, and thereby a sulfur-containing amino acid-producing bacterium, and a method for producing a compound such as a sulfur-containing amino acid are provided. A sulfur-containing amino acid, a related substance thereof, or a mixture of these can be produced by culturing a bacterium belonging to the family Enterobacteriaceae, which has a sulfur-containing amino acid-producing ability and has been modified so that the activity of the protein encoded by the yeeE gene, for example, the protein of the following (A) or (B), is increased in a medium, and collecting a sulfur-containing amino acid, a related substance thereof, or a mixture of them from the medium: (A) a protein having the amino acid sequence of SEQ ID NO: 14, (B) a protein having the amino acid sequence of SEQ ID NO: 14 but which includes one or several amino acid substitutions, deletions, insertions, or additions, and when the intracellular activity of this protein is increased, the ability of the bacterium to produce a sulfur-containing amino acid is improved.

    摘要: Provided herein are methods for treating planktonic bacteria or a biofilm. The methods include contacting the planktonic bacteria or biofilm with an effective amount of an isolated Citrobacter freundii colicin A polypeptide, wherein the polypeptide has an antibacterial activity against the planktonic bacteria or the biofilm. Methods are also provided herein for treating a subject that has a bacterial infection, for example caused by a biofilm. The methods can be used to treat a biofilm on a living or non-living surface. Also provided herein are Citrobacter freundii colicin A polypeptides that have an antibacterial activity against planktonic bacteria or surface attached bacteria, and nucleic acid sequences encoding the polypeptides. Medical devices comprising a surface having an antimicrobial effective amount of a Citrobacter freundii colicin A polypeptide, or a nucleic acid molecule encoding the polypeptide, are also disclosed.
