Abstract:
Sheep erythrocytes stabilized by aldehydes were coated with soluble antigens prepared from Legionne-lla pneumophila 1st serogroup Philadelphia 1 strainkindly provided by Center for Disease Control, Atlanta, GA. USA. We found the antibody liter raised more than fourfold during the convalescence of the guinea pigs inoculated with the above antigen. During October to December 1982, sera from 601 blood donors and patients without respiatory infection were tested for Legionnella antibodies by PHA test. 54 of 601 persons or 9% were found to have an antibody titer≥1 : 128.
