Caption:
This photomicrograph of a direct fluorescent antibody (DFA) stained specimen, used to detect the presence of fluorescent treponemal antibody (FTA) antigen, revealed a number of Treponema pallidum bacteria, glowing before the dark background. T. pallidum bacteria, if present, will fluoresce when viewed with DFA stain in the presence of FTA bound to the bacterium’s cell wall.
