A survey of anti-Ostertagia ostertagii antibody levels in bulk tank milk samples (BTM) in dairy herds in Lower Silesia Region (Poland).

摘要: This work presents serological evidence of cattle ostertagiosis in the Lower Silesia Region (Poland), based on measurement antibodies bulk tank milk (BTM) samples. It represents first this parasite examined with use ELISA test and samples Poland. The prevalence Ostertagia ostertagii was determined BTM from 32 dairy herds. Antibodies to O. were demonstrated all optical density ratio (ODR) varied -0.088 1.024. mean ODR value region 0.53.
