№ 3 - 2014 pose of this study was to conduct a serological monitoring of chlamydiosis in dairy cattle in the Urals region and determination of the basic strategic directions of its elimination. <...> Serological monitoring of chlamydia in cattle in dairy herds in the Urals region was carried. <...> For this examined samples of serum from cows and heifers from herds with dysfunction of reproduction by ELISA. <...> In all examined herds noted the presence antibodies to Chlamydophila abortus in cows, seroprevalence in 2013 was 64.0%, in 2014 - 56.4%. <...> The developed strategy for the elimination of chlamydia in dairy cattle herds, including diagnostic testing of breeding stock by ELISA, treatment and veterinary sanitary measures as well as measures in points insemination of animals. <...> In the implementation of all necessary countermeasures in full, may be achieved reduction of pathologies reproduction in dairy herds. <...> Нежданов, А.Г.
