For culture-negative meningitis, use of the latex agglutination test for detection of bacterial antigen in the CSF has a sensitivity of only 7%. Routine use of the latex agglutination test may not contribute to the management of suspected acute bacterial meningitis, since patients are treated on the basis of their clinical presentations and CSF findings.

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 ...

Sera submitted to the Texas Department of Health for the serodiagnosis of Rickettsia typhi were tested by the microimmunofluorescent antibody technique and a new latex agglutination procedure. Results indicated that the latex agglutination test was sensitive and specific and would serve well as a first-line screening test for murine typhus.

AIMS To examine A, C, Y, and W135 Neisseria meningitidis serogroup characterisation by ultrasonic standing wave enhanced latex agglutination tests (USELATs) of clinical samples. In addition, to determine USELAT enhancement of detection sensitivity for the individual antigens compared with conventional card latex agglutination tests (LATs). METHODS Wellcogen (Abbott Murex), Slidex meningite ki...

One hundred strains of Escherichia coli were tested for the production of the heat-labile enterotoxin by the Y1 adrenal cell test and a commercially available reversed passive latex agglutination test. The strains were grown in Casamino Acids-yeast extract broth, and filtered culture supernatants were tested for the presence of heat-labile enterotoxin. There was perfect correlation between the ...

The serum of patients with rheumatoid arthritis contains a factor which causes agglutination of sensitized particulate bodies. This phenomenon has been demonstrated using sheep red cells (Waaler, 1940), collodion particles (Wallis, 1946), bacteria (Wager, 1950), polysterene latex particles (Singer and Plotz, 1956), and bentonite (Bozicevich, Bunim, Freund, and Ward, 1958).
