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

Opis:: The objective of this study was to estimate a herd-level seroprevalence of bovine herpesvirus type 1 (BHV-1) in herds with clinical symptoms of the respiratory tract. Eighty-three herds with suspected BHV-1 infection were selected and divided into two categories with respect to their size: small (n=27) and large herds (n=56). Samples were collected from calves, heifers and cows older than 24 months. Seroprevalence was determined using the gB ELISA test. The herd level seroprevalence was estimated as 53% (44/83) in the tested herds, 11.1% (3/27) in the small herds and 73.2% (41/56) in the large herds. Our study suggests that the current biosecurity measures still warrant improvement.
