An improved fluorescent monoclonal antibody staining kit, Cholera DFA, for direct detection and enumeration of Vibrio cholerae O1 has been developed, employing a highly specific anti-A antigen monoclonal antibody, COLTA, labeled with fluorescein isothiocyanate (FITC). An optimized quantity of anti-photobleaching agent is used in a glycerol mounting medium to retard the rapid fading of immunofluorescent stained cells during fluorescent microscopy, thus enabling prolonged inspection of individual fields, as well as improved photographic recording of results without loss of fluorescence intensity. When tested for specificity, all 30 strains of V. cholerae O1 reacted with Cholera DFA, whereas 100 heterologous species examined did not, yielding 100% specificity for all strains examined in this study. A field trial was conducted in Bangladesh, employing Cholera DFA and the results were compared with those obtained by conventional culture methods. Of 44 diarrheal stool specimens tested, Cholera DFA was positive for V. cholerae O1 in all culture-positive stool specimens and negative for all culture-negative stool specimens. The procedure is sensitive and highly specific, as well as simple, i.e., less complex than the indirect fluorescent assay, requiring only one reagent and less than 30 min to complete the staining process, while retarding rapid fading that often occurs with fluorescent microscopy.
