[Incidence of Coxiella burnetti and Chlamydia psittaci in cattle in southern Bohemia].

In 1986 and 1987 in six districts and 22 localities of the Southern Bohemian region, and in one district and one locality of the Western Bohemian region the total of 747 head of cattle was examined by a microagglutination method (MAR) and complement fixation method (KFR) for antibodies to Coxiella burnetii and Chlamydia psittaci. The positivity of C. burnetii detection was 44.4% in MAR and 16.5% in KFR. The positivity of Chl. psittaci detection was 7.1%. The widespread incidence and highly positive results of coxiellosis findings in the given regions are especially remarkable. This circumstance--for the closed herd turnover in this country has been abandoned--can be considered a potential risk of Q fever outbreak in the human population not only in the Southern Bohemian region, but also in other localities.
