[Research on IgG and IgM anti-Legionella pneumophila group 1 in 101 subjects with pneumonitis].
IgG and IgM antibodies anti-Legionella pneumophila group 1 were detected by fluorescent-antibody technique according to Wilkinson et al. (1979) in the sera of 101 patients with pneumonia. Positive sera were tested by the same authors' modified technique (1981). Our results indicate a low specificity of the first method, since 43.7% of the IgG-positive sera and all the IgM-positive sera were negative when tested by the modified method. 8.9% of the sera were IgG-positive, confirming the relatively high diffusion of the microorganism. In none of the studied patients an increase on antibody titer or an IgM-positivity were observed; in none of the studied cases of pneumonia the aetiological agent was therefore Legionella pneumophila.
