The use of monoclonal antibodies in the diagnosis of partially treated Pseudomonas aeruginosa meningitis: patient report.

The objective of this study was to evaluate the efficacy of mouse anti-pseudomonas monoclonal antibodies to detect small numbers of pathogenic pseudomonas in the spinal fluid of a patient who had been treated with antibiotics for meningitis. Anti-605 monoclonal antibody against Pseudomonas aeruginosa PAC 605, a rough mutant, showed sensitivity similar to that of anti-Fisher 1 monoclonal antibody in detecting P. aeruginosa Fisher 1 antigens in boiled spinal fluid drawn from a patient with a P. aeruginosa perispinal abscess and partially treated meningitis.
