DETECTION OF BACTERIAL ANTIGENS BY STAPHYLOCOCCAL CO-AGGLUTINATION TEST

Latex agglutination test for rapid detection of bacterial antigens in body fluids.

A modified latex agglutination (LA) test performed on glass slides was evaluated for the detection of Streptococcus pneumoniae (Pn), Hemophilus influenzae type b (Hib), and K1 antigens in serum, cerebrospinal fluid (CSF), nasopharyngeal secretions, and other body fluids in patients suspected of having infection. Forty-eight, 61, and 31 specimens were tested for the presence of Pn, Hib, and K1 a...

Detection of rotavirus by Latex Agglutination Test (Rotales); Comparison with Electron Microscopy and Complement Fixation Test

An evaluation of the staphylococcal co-agglutination test for the detection of group A rotavirus in human faeces.

The group A rotavirus staphylococcal co-agglutination test was evaluated and its sensitivity and specificity compared with an in-house enzyme-linked immunosorbent assay (ELISA) and a commercial latex agglutination test (Rotalex). In addition, the storage stability of the staphylococcal reagents was ascertained. Examination of 136 clarified suspensions of diarrhoeal faeces by the staphylococcal ...

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...

Single-tube mixed agglutination test for the detection of staphylococcal protein A.

A simple, rapid mixed agglutination test using sheep erythrocytes (SRBC) sensitized with rabbit hemolysin and intact viable staphylococci is described for the detection of bound staphylococcal protein A. Soluble protein A was heat extracted from 50 clinical isolates as well as the Cowan I and Wood 46 strains of Staphylococcus aureus and titered by a hemagglutination test using sensitized SRBC a...
