FIG. 6.

Digital analysis of fluorescence microscopy using rabbit antiserum and FITC labeling of B. henselae Houston-1 cultured in media alone (▧) or with HMEC-1 (▪) for 5 days. Cultures were reacted with NRS (A) or with rabbit serum specific for the 17-kDa protein (B). Samples were reacted with antiserum, stained with FITC, and examined by fluorescence microscopy. Digital images were captured and reported as a ratio of FITC (green fluorescence) to DNA (blue fluorescence).
