Development of Vaccines to Prevent Wound Infections Due to Anaerobic Bacteria

摘要

Progress on the two major objectives of this contract were made during this year. One lot of capsular polysaccharide of Bacteroides fragilis vaccine was tested for protective capacity in mice and found to function to induce a protective response. One human volunteer was immunized without adverse reactions occurring and the immunogenicity will be assessed. On the second specific aim, major progress was made in producing a special T cell factor by cloning lymphocytes in vitro to produce the protective lymphokine. A small molecular weight antigen specific factor has been produced from hybridoma clones. This factor is of T cell origin and protects mice against experimental infection with Bacteroides fragilis.
