چکیده

Detection of group B streptococcus (GBS) antigen in urine by latex particle agglutination (LPA) may facilitate the rapid diagnosis of GBS sepsis. We sought to compare three commercial LPA assays with specimens that were spiked with type-specific antigen, group-specific antigen, or type III organisms. There were sensitivity differences between the assays, but the Bactigen assay performed best, detecting as little as 1 ng of GBS group-specific antigen per ml in urine and as few as 10(5) CFU of GBS type III organisms per ml in urine, serum, and cerebrospinal fluid.

Experience with rapid latex agglutination testing for group A streptococcal pharyngitis in a pediatric group office laboratory.

We evaluated 2401 patients with suspected streptococcal pharyngitis with the Culturette 10-minute Group A Strep ID test during a 6-month period in order to determine its suitability for rapid diagnosis in a busy private office practice. Duplicate throat swabs were obtained for each child, and latex agglutination was performed within 15 minutes. In children with negative latex agglutination resu...

Monoclonal antibody to streptococcal group B carbohydrate: applications in latex agglutination and immunoprecipitin assays.

Two monoclonal mouse antibodies with specificities for group B streptococcal capsular antigens were evaluated in assays for the identification of group B streptococci (GBS). One of these antibodies (A9) was shown to precipitate group B carbohydrate antigen in reactions with both purified group B antigen and antigen present in autoclave or enzyme extracts of GBS. A9 antibody was also specific fo...

Comparison of three commercially available assays for detection of varicella-zoster virus antibody.

Three commercially available diagnostic assays for the detection of antibodies to varicella-zoster virus were evaluated to determine which would be the most suitable for our clinical laboratory. Three different methods were examined: an enzyme-linked immunosorbent assay (ELISA), latex agglutination (LA), and an indirect fluorescent-antibody technique. For the 141 serum specimens tested, the ELI...

Comparison of staphylococcal coagglutination, latex agglutination, and counterimmunoelectrophoresis for bacterial antigen detection.

Soluble antigens of Haemophilus influenzae type b, Streptococcus pneumoniae, Neisseria meningitidis, and group B streptococcus were looked for in cerebrospinal fluid, serum, and urine by using the staphylococcal coagglutination test, latex agglutination test, and counterimmunoelectrophoresis. The staphylococcal coaggultination and latex agglutination tests were more sensitive than counterimmuno...

Comparison of a latex agglutination assay and an enzyme-linked immunosorbent assay for detecting cholera toxin.

To determine the pandemic potential of Vibrio cholerae, one must demonstrate both the presence of O1 antigen and the production of enterotoxin (CT). Tissue culture or enzyme-linked immunosorbent assays (ELISAs) for CT have been limited to research and reference laboratories. A kit for detecting CT by reversed passive latex agglutination is now commercially available and was used to test 168 str...
