Fluorescent Antibody Staining Test for Rapid Diagnosis of Shigella Dysenteriae 1 Infection

An indirect fluorescent antibody test for rapid detection of Shigella dysenteriae 1 in diarrheal stools was developed. A diagnosis could be made within 90 min of submission of specimens to the laboratory. On comparison with culture results, the test had a sensitivity of 92%, a specificity of 93%, and positive and negative predictive values of 94% and 92%, respectively.
