Development of a quantitative immunofluorescence assay for detection of Stenotrophomonas maltophilia antibodies in patients with cystic fibrosis  P. Gonçalves Vidigal, D. Schmidt, F. Stehling, U. Mellies, E. Steinmann, J. Buer, P.-M. Rath, J.

Fig. 1 A) Antibody levels of S. maltophilia (Sm) whole cell in serum samples from healthy subjects (healthy), CF patients with chronic (CF chronic Sm), intermittent (CF intermittent Sm), and never Sm without P. aeruginosa (CF never Sm/Pa). Antibody levels are reported as titres. P values<0.0005 by non-parametric test were considered significantly different. B) Comparison of antibody titre between CF “never Sm/Pa” and CF never Sm but chronic Pa. Antibody titres did not differed between the groups (P=0.1898).

ROC data (area=0.8815; std. error=0.052; P=0.0002) of CF patients never colonised S. maltophilia/P. aeruginosa (Sm/Pa) versus CF patients with chronic S. maltophilia (Sm).
