| Abstract | ||
| Milk samples and lab-made yoghurt were used to investigate the antibacterial effect of bifidobacteria bifidum on Staphylococcus aureus pathogen. All samples were analyzed microbiologically for presence of S. aureus when fresh and after 2 and 5 days of storage at refrigeration temperature for milk and yoghurt respectively proven to be contaminated with S.aureus from infected, non treated dairy cows and experimentally milk inoculated with S.oureus (5x104 cfu/ml). the obtained results indicated that there were adequate difference in S.oureus count in the examined samples treated with bifidobacteria bifidum from zero time till the 2nd day of storage in bifudus milk. The reduction of S.aureus were 100% at 2nd, 3rd, 4th and 5th days of storage in bifidus yoghurt manufactured from inoculated milk with S.aureus. The current study indicates that Bifidobacteria may restrict and/ or inhibit S.aureus in milk and yoghurt. | ||
