Means and their standard errors of mRNA levels of SAA3, HP, and CP genes in mammary gland epithelial cells (MEC) depending on the mammary gland health status: CoPS (N = 8), CoNS (N = 7), or H (N = 8). SAA3 – serum amyloid A3 gene, HP – haptoglobin gene, CP – ceruloplasmin gene, CoPS – coagulase-positive staphylococci, CoNS – coagulase-negative staphylococci, H – samples free from bacteria. The value within the same gene with different letters differs significantly: a, b – at p ≤ 0.05. The value within the same gene with different numbers differs at the trend level: 1,2 – at p < 0.1
