Rapid Immunoassay for detection of Escherichia coli O157 directly from stool specimens.
    Journal of clinical microbiology, 1996, Volume: 34, Issue:4

    A new and rapid ( < 1 h) enzyme-linked immunosorbent assay (ELISA) was compared with conventional sorbitol-MacConkey agar (SMAC) culture for the detection of Escherichia coli O157 from stool specimens. Among 34 positive specimens, confirmed by colony-sweeping and immunofluorescence stain methods, 6 did not exhibit visible sorbitol-negative colonies on SMAC. These six specimens would have been considered to be negative if SMAC alone had been used. The ELISA detected 31 of the 34 positive samples, including 5 of the above-mentioned 6 false-negative samples, resulting in a sensitivity and specificity of 91.2 and 99.5%, respectively. Cross-reactivity with other enteric pathogens was not noted by ELISA. The SMAC method had a sensitivity and specificity of 82.4 and 100%, respectively. The ELISA-negative specimens do not require culture confirmation, whereas positive results must be considered to be presumptive until confirmed by culture. The test is accurate and is easy to perform, making it a very efficient method for screening stool specimens for E. coli O157.

Rapid detection and isolation of shiga-like toxin (verocytotoxin)-producing Escherichia coli by direct testing of individual enterohemolytic colonies from washed sheep blood agar plates in the VTEC-RPLA assay.
    Journal of clinical microbiology, 1996, Volume: 34, Issue:11

    By combining the enterohemolysin test and the VTEC-RPLA test (specific for the detection of Shiga-like toxin I [SLT-I], SLT-II, and SLT-IIc), single colonies of SLT-producing Escherichia coli were found to constitute between 0.03 and 68.1% of the coliform flora in human stool cultures and were isolated and characterized within 72 to 96 h.
