  1. Prevalence of Legionella pneumophila serogroup 1 antibodies in blood donors.

    Article - En anglais

    The prevalence of anti-Legionella pneumophila serogroup 1 antibodies in 777 blood donors of the Turin area was determined by the indirect immunofluorescence assay (IFA) and by the microagglutination test (MA).

    Low titers (IFA of 1/16 and MA of 1/8) were found in 0.3% of the subjects.

    A statistically significant difference was not observed by sex and by age for IFA titers, but was noted by sex for MA titers of = 1/4 (p<0.05).

    The upper limit of normal titer was<1/8 by IFA and<1/4 by MA at 15% cutoff level and 1/8 by IFA and 1/4 by MA at 1% cutoff level.

    In conclusion, the prevalence of antibodies in the Turin area was very low ; IFA titers of = 1/64 and MA titers of>1/16 can be considered as presumptive of infection in a single serum specimen of a patient with pneumonia ; no change in the epidemiology of the disease was observed in the recent years.
