Abstract
A study of the resistance of microflora isolated from the secret of udder patients with cow mastitis showed high resistance of isolated microorganisms to antibiotics of penicillin, tetracycline cephalosporin, polymyxin, macrolides, glycopeptides and lincosamides. In determining the sensitivity of isolated microorganisms to complex antibacterial drugs, it was found that all strains of S. agalactiae showed resistance to all the drugs studied (Bayoclox DC, Mamifort secado, Mastiet forte, Mastizim, Norfloxamast, Primalact, C-mast). E. coli was resistant to 9,9% of the study drugs (Bayoclox DC, Mamifort secado, Mastizim, C-mast). S. aureus – to 15,9% of drugs. Antibiotic resistance of the groups of penicillins, tetracyclines, linkosamides of 15,9 generation was recorded in 26,4% of the strains studied. 86% E. col, 88% S. aureus and 62,5% S. agalactiae were resistant to fluoroquinolone preparations. 50,0% E. col, 1% S. aureus and 100% S. agalactiae were resistant to cefazoline antibiotics. E. coli did not show resistance to the group of aminoglycosides (gentamicin); of the isolates S. aureus and S. agalactiae, 56,6% were resistant.
