We had examined antibody titers against Legionella spp. of patients' sera which were mainly sent from other hospitals, performed with the indirect fluorescent antibody (IFA) method. The clinical status of the cases diagnosed as Legionella pneumonia serologically, were also studied. Out of 105 cases with clinically suspected Legionella pneumonia, 15 cases (14.3%) were seropositive. In 9 out of the 15 cases (60.0%) were caused by Legionella pneumophila serogroup 1. Clinical outline of these 15 cases did not contradict those reported in the literature, and erythromycin was effective in many cases. Significant rises (more than four times) of the titer were observed 3 to 4 weeks after onset in most of cases. We would like to emphasize that this should be performed serodiagnosis of Legionella pneumonia.
