Comparing anti legionella antibody titers between hospital workers and healthy population; a case-control study.
Pak J Med Sci Jan ;27(1):82-4.

Objective: To determinate Legionella antibody titers among healthcare workers and healthy population. Methodology: The blood samples were collected from all 360 subjects (case and control) and the ELISA method was used to assess the anti-Legionella IgG titer. The statistical analyses were performed using the SPSS software version 13. Results: The mean of antibody titer was 5 ± 0.38 in all participants. There was a 95.6% negative and a 2.2% positive antibody titer in the case group. In the control group, the negativity rate was 91.1% and the positivity rate was 6.7%. The antibody titer difference between two groups was not statistically significant (P value= 0.167). Conclusion: The total antibody titer in both healthcare workers and healthy population was not high and the difference was not significant.
