Detection of urinary antigens of Legionella pneumophila serogroup 12 by broad-spectrum enzyme-linked immunosorbent assay.

Evaluation of the Binax and Biotest urinary antigen kits for detection of Legionnaires' disease due to multiple serogroups and species of Legionella.

The Binax and the Biotest urinary antigen kits for the detection of Legionnaires' disease caused by organisms other than Legionella pneumophila were compared by testing 45 urine samples from non-Legionella pneumophila serogroup 1 patients previously positive in a broad-spectrum enzyme-linked immunosorbent assay (ELISA). Eighteen were positive with the Binax kit, and 13 were positive with the Bi...

Characterization of a lipoprotein common to Legionella species as a urinary broad-spectrum antigen for diagnosis of Legionnaires' disease.

We have previously identified the Legionella 19-kDa peptidoglycan-associated lipoprotein (PAL) as a species-common immunodominant antigen. We describe here for the first time the excretion and detection of the PAL antigen in infected urine specimens, which is useful for the diagnosis of Legionnaires' disease. Rabbit anti-PAL immunoglobulin G (IgG) antibody was produced by immunization with the ...

Immunologic diversity among serogroup 1 Legionella pneumophila urinary antigens demonstrated by monoclonal antibody enzyme-linked immunosorbent assays.

We tested urine specimens from 222 patients with serogroup 1 Legionella pneumophila pneumonia in two enzyme-linked immunosorbent assays (ELISAs) which used different monoclonal antibodies (A and B) as detector antibodies. Of 171 specimens which contained enough antigen to be detected in the ELISAs, 169 reacted in only one of the two assays. A total of 25 patients whose infections were acquired ...

An ELISA test for the detection of antibodies to Legionella pneumophila.

An enzyme-linked immunosorbent assay (ELISA) test has been developed to detect antibodies to Legionella pneumophila serogroup 1. There is good correlation between indirect fluorescent antibody (IFA) and ELISA titres but ELISA is more sensitive.

Detection of IgM antibodies against Legionella pneumophila serogroup 1 in Malaysian blood donors and patients with respiratory illnesses: evaluation of enzyme-linked immunosorbent assay and indirect immunofluorescence assay.
