Latex agglutination test for detection of Escherichia coli serotype O157

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

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.

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 ...

Latex agglutination test for detection of antibodies to Toxoplasma gondii.

A resurgence of interest in Toxoplasma gondii has occurred because this coccidian parasite causes lethal infections in immunologically compromised hosts and is responsible for at least 3,000 congenitally infected infants in the United States annually. Thus, rapid, specific, and inexpensive serologic tests are required for routine screening of patients, especially pregnant women. We have develop...
