| Abstract: | OBJECTIVE To prepare and identify the antibody-serum or monoclonal antibody of alginate, and investigate the protesting role of antibody of alginate against bacterial biofilm (BBF) disease caused by Pseudomonas aeruginosa in nosocomial infection. METHODS Antibody-serum of alginate was acquired by routine immunity method. The spleen cell was obtained from BALB/c mice by programmed immunization and then was fused with myeloma cell line SP2/0. The positive clones were obtained by ELISA method. SEM was used to observe the form of BBF. RESULTS Two kinds of monoclonal antibody of alginate were obtained; P. aeruginosa BBF alginate was decreased by antibody of alginate. CONCLUSIONS The neutralization role of antibody of alginate is one of the mechanism that antibody of alginate prevents and cures P. aeruginosa BBF. |
