“…Such assays can take up to five days to perform (Anon, 1978). Antibody technology is now beginning to make an impact in microbiological areas, and several immunoassays for Salmonella have been described (Krysinski & Heimsch, 1977;Mattingly, 1984;Ibrahim et ai, 1986;Hadfield et al, 1987) which are available commercially as kits. One of the kits has been declared official first-action by the Association of Official Analytical Chemists (Flowers et al, 1986).…”

Rapid antibody-based assays have been developed for the detection of Salmonella enteritidis in eggs. The assays consist of an initial non-selective enrichment step in a chemically defined medium followed by either an indirect competitive enzyme-linked immunosorbent assay or an antibody-capture enzyme-linked immunosorbent assay. The limits of detection are 6 × 10 5 cells and 5×10 4 cells/ml respectively, and both assays are highly reproducible. A positive result is obtained from an egg inoculated with 10 S. enteritidis cells in 18 h using either assay. The potential for further improvements is discussed.

“…To this end, researchers have used antibodies or antigens in the same assay zone labeled with (a) different fluorescent molecules (6,7), (b) different radioactive species (8 -10), (c) different enzymes (11,12), (d) a mixture of radioactive species and enzymes (13), (e) metal ions (14), (f) colored latex particles (15), and (g) particles of different sizes (16). The various detection schemes used in these multianalyte assays are based on a change in one or more of the following signals: absorbance, steady-state fluorescence, fluorescence lifetime, chemiluminescence, radioactivity, electrochemical response, laser light scattering, and frequency of apiezoelectric quartz crystal, upon the binding event(s) (6 -20).…”

“…These include the Oxoid Salmonella Latex Kit (Oxoid, Basingstoke, UK) designed to be used with the Oxoid Rapid Salmonella Test Kit (Holbrook et al, 1989); the Microscreen Salmonella Latex Slide Agglutination Test (Mercia Diagnostics Ltd, UK); the Wellcolex ® Colour Salmonella Test (Remel Inc, USA) (Hadfield et al, 1987a, b); and the Spectate ® Salmonella test (Rhône Poulenc Diagnostics Ltd, UK) (Clark et al, 1989). The latter two kits use mixtures of coloured latex particles that allow not only detection but also serogrouping of Salmonella.…”
