Trueperella (T.) pyogenes is an opportunistic pathogen that causes suppu-rative diseases in domestic animals. In this work, the properties, pathogenesis and phenotypic diversity of T. pyogenes isolates from bovine mastitis were studied. Both pyolysin (plo) and collagen-binding protein (cbp) virulence factor genes were detected by PCR in all T. pyogenes isolates (n = 50). Using the tissue culture plate method, 90% of T. pyogenes isolates were able to form biofilms. The minimum inhibitory concentrations (MICs) of 13 antimicrobials against T. pyogenes isolates were determined. High susceptibility was observed to rifampin (96%), ampicillin (94%), ciprofloxacin (94%), and penicillin (92%), while low susceptibility was found to trimethoprim-sulphamethoxazole (10%) and bacitracin (2%). The intra-cellular assay revealed that T. pyogenes isolates had different cytopathogenic ef-fects on cells. The high percentage (28.6%) of T. pyogenes isolates suggests that this bacterium is an important contributor to mastitis. Moreover, the high occur-rence of multidrug resistance, biofilm production, intracellular survival, and the temporal dynamics of T. pyogenes interactions are key factors for a better under-standing of how immunity acts on infections with these bacteria and how they evade immuné surveillance, thus highlighting the need for the prudent use of an-timicrobial agents in veterinary medicine.
Key words: Trueperella pyogenes, bovine mastitis, biofilm, virulence factor, antimicrobial susceptibility Vissza
