**7. Role of probiotics and prebiotics in prevention of** *S. aureus* **infection**

As mastitis is the most dangerous and costly disease of dairy industry. The use of antibiotics leads to the development of drug resistance due to which it becomes untreatable disease. Also, the presence of antibiotic residues in milk and dairy products render it unused able for consumer. So, there is another approach for prevention and treatment of mastitis [64]. Many successful experiments have been performed in past by using bacteriocin-based products. Nisin has been used as a

commercial product for the disinfection of teats. And lacticin is used in the dry cow therapy for sealing teat canal at the time of drying off of cow [54, 65].
