The staff of Reference Laboratory for Cattle Diseases within the FGBI “Federal Centre for Animal Health” subordinate to the Rosselkhoznadzor performed a number of serological and molecular-biological tests within monitoring of infectious disease agent spread rate.
891 sera samples from cattle of different age and sex from different RF regions were tested by ELISA.
63 out of 71 samples (88.7%) demonstrated antibodies against infectious bovine rhinotracheitis (IBR); antibodies against bovine viral diarrhea (BVD) were detected in 48 out of 61 samples (78.6%); 71 out of 71 samples (100%) had antibodies against respiratory syncytial virus (RSV); antibodies against bovine mycoplasmosis were found in 2 out of 11 samples (18.1%); 10 out of 10 samples (100%) showed antibodies against bovine pasteurellosis; 201 out of 225 samples (89.3%) had antibodies against bovine parainfluenza-3 (BP-3); antibodies against bovine rotavirus were found in 1 out of 56 (1.7%) samples; 37 out of 56 (66%) samples demonstrated antibodies against bovine coronavirus; 8 out of 8 samples (100%) contained antibodies against bovine clostridiosis (alpha toxin) and 4 out of 8 (50%) of samples against bovine clostrdosis (epsilon toxin).
916 samples of biological material from animals imported from Germany and USA were tested for Schmallenberg disease virus and bluetongue by PCR. The genomes of the mentioned viruses were not detected. But in 2.3% of the samples bovine viral diarrhea virus genome was detected by PCR, in 8.6% of samples – bovine rotavirus genome; in 3.3% - bovine coronavirus genome; in 54% - bovine leucosis and 2.5% respiratory syncytial virus (RSV) genome.
