Comparison of Two Commercial Enzyme-Linked Immunosorbent Assays with an Immunofluorescence Assay for Detection of Legionella pneumophila Types

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.

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

The first Canadian case of Legionella pneumophila serogroup 12 infection is reported. The initial diagnosis was made with a urine specimen by a broad-spectrum enzyme-linked immunosorbent assay; further serogrouping was done by indirect fluorescent-antibody and tube agglutination tests. This case emphasizes the importance of multivalent urinary antigen detection for the diagnosis of legionellosis.

Adaptation of an indirect enzyme-linked immunosorbent assay by purified gp51SU for detection of antibodies to bovine leukemia virus

The objective of this study was to compare an indirect ELISA, based on a purified 60 kDa envelope glycoprotein (gp51SU), with a Pourquire indirect ELISA for the detection of antibodies to the bovine leukemia virus. For conducting this research, 340 serum samples were collected from two different breeds of cows (Sarabi and Holestin) in different herds. Commercial ELISA revealed positive results ...

Detection of antibodies against Legionella pneumophila serogroups 1 to 6 and the Leiden-1 strain by micro ELISA and immunofluorescence assay.

One hundred and seventy-five human sera were tested for the presence of type-specific antibodies against L pneumophila serogroups 1 to 6 and the Leiden-1 strain by means of an enzyme linked immunosorbent assay (ELISA) and compared with the results obtained by the indirect immunofluorescence assay (IFA). A high correlation (correlation coefficient 0.92) between both methods was found. No consist...
