Rapid test for identification of heat-labile enterotoxin-producing Escherichia coli colonies.
نویسندگان
چکیده
A latex particle agglutination test is described which is suitable for the recognition of heat-labile enterotoxin-producing colonies of Escherichia coli immediately after primary culture on a variety of commonly used enteric diagnostic media. The test is simple and economical to perform, and the results are available in minutes.

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.
متن کاملRadial passive immune hemolysis assay for detection of heat-labile enterotoxin produced by individual colonies of Escherichia coli or Vibrio cholerae.
A rapid screening test has been developed to detect heat-labile enterotoxin produced by individual colonies of Escherichia coli or Vibrio cholerae growing on media solidified with agar. The applicability of this method for isolating tox mutants of E. coli and V. cholerae has been demonstrated.
متن کاملModified Elek test for detection of heat-labile enterotoxin of enterotoxigenic Escherichia coli.
The Elek test was modified for detection of the heat-labile enterotoxin of enterotoxigenic Escherichia coli. A total of 164 strains of E. coli were tested by the modified Elek test, and the results correlated well with those of the Chinese hamster ovary cell assay and passive immune hemolysis. It is concluded that the modified Elek test is a simple and reproducible assay method for identificati...
متن کاملConstruction and Expression of a Fused Gene for B Subunit of the Heat-Labile and a Truncated Form of the Heat-Stable Enterotoxins in Escherichia coli
Elaboration of different toxins by enterotoxigenic E. coli has been considered as one of the main virulence factors contributing to the manifestation of disease caused by these microorganisms. Various strategies have been employed to raise antibodies against these toxins as a line of defense. In this study, the 3’ terminus of the gene that codes for the binding subunit of the heat-labile entero...
متن کاملRapid detection by a coagglutination test of heat-labile enterotoxin in cell lysates from blood agar-grown Escherichia coli.
Colonies of Escherichia coli from blood agar plates were suspended and lysed in saline containing polymyxin B and a detergent (Triton X-100). The lysates were assayed for heat-labile enterotoxin (LT) by a coagglutination test (coa-test). The coa-test reagent consisted of Formalin-treated and heat-killed cells of Staphylococcus aureus, strain Cowan 1, sensitized with a high-titer rabbit anti-LT ...
