This paper presents the results of the effect of trichloroacetic acid (TCA) at two different temperatures and the effect of a mixture of detergents (D) on Coxiella burnetii. Both TCA and D caused a large destruction of C. burnetii cells. In both cases complexes of high-molar-mass components from the outer membrane were extracted. In the D case not only proteins but a mixture with other high-molar-mass structures were released from the destroyed cells. By extraction of TCA, the antigenic complex composed of lipopolysaccharides (LPS), proteins and phospholipids was released. The effect of the D mixture on C. burnetii causes their complete destruction. The TCA causes a surface destruction of cells but it does not cause complete disintegration. The small-cell variants (SCV) in both cases were shown to be more stable compared to the large-cell variants (LCV).
