Antibiotic resistance of Staphylococcus aureus isolated from the milk of a cow with mastitis in selected countries of the Europe, Western Balkans, Asia and Africa

Clinical, subclinical and chronic staphylococcal mastitis of cattle is a frequent phenomenon on farms. The skin of the udder and the environment are not sterile, which is why it is important to maintain high hygiene standards in the production of milk and milk products, in order to prevent the transmission of pathogens into drinking milk and milk products. Laboratory detection of the causative agent of mastitis is important in order to detect the disease and prevent food poisoning in consumers. In contrast to subclinical, clinically manifest mastitis, it is often treated empirically. Such practices lead to the spread of antibiotic resistance. The purpose of the study was to investigate the prevalence of antibiotic resistance of Staphylococcus aureus, the presence of MRSA and the mecA gene in isolates from the dairy sector in many regions in order to pay attention in time to the current prevalence and prevent the spread of resistant bacterial isolates to animals and humans. Prevention of bovine mastitis requires finding effective vaccines, effective antibiotic therapy, rationalizing antibiotic consumption, as well as finding new antibiotics and new alternative means of treatment.
