Detection of Escherichia coli Antigens by a Latex Agglutination Test

Latex agglutination test for detection of Escherichia coli serotype O157.

The value of a latex agglutination test (Escherichia coli O157 latex test; Oxoid Ltd.) for rapid presumptive detection of E. coli serotype O157:H7 was determined by laboratory trials and during an outbreak of hemorrhagic colitis. The latex test was found to be a simple, highly efficient and reliable test in detecting E. coli O157:H7 with 100% sensitivity and specificity. It was also found that ...

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

Evaluation of a reversed passive latex agglutination test for detection of Escherichia coli heat-labile toxin in culture supernatants.

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 ...

Rapid latex particle agglutination test for Escherichia coli strains of porcine origin producing heat-labile enterotoxin.

A latex particle agglutination test previously shown to be suitable for the rapid identification of Escherichia coli strains of human origin producing heat-labile enterotoxin (R. A. Finkelstein and Z. Yang, J. Clin. Microbiol. 18:23-28) is equally applicable to strains of porcine origin.

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...
