SUMMARY An assay for rapidly detecting and determining sparse populations of vegetative bacteria or bacterial spores (minimum number about 500 ; 2 to 4 x Io-lOg. equivalent bacterial dry weight) is described. A sample is treated with 1251-labelled purified homologous antibody, filtered and washed on a Millipore membrane filter, and the radioactivity of the separated labelled immune complex is measured. The assay is specific, accurate and completed within 8 to 10 min. Sensitivity and accuracy decrease if the assay is applied to samples that contain particulate matter that non- specifically attaches antibody and is retained by a membrane filter. This type of interference is decreased by pretreating samples with clarified normal rabbit serum for a few minutes before assay.
