چکیده

The aim of this study was to investigate the antibacterial effect of the recombinant camel Lactoferrampin-Lactoferricin on the growth rate of Staphylococcus aureus bacteria, one of the causes of mastitis in dairy cows. This peptide, which was prepared through a previous study in Biotechnology Laboratory of Animal Science Department, Faculty of Agriculture, Ferdowsi University of Mashhad. Antibacterial effects of this peptide was assessed by Count Colonies on Methicillin-resistant Staphylococcus aureus -PTCC 1764- and Staphylococcus aureus -ATCC 25923-. Heat resistance properties and freeze drying process of the peptide were evaluated by disk diffusion method in triplicate. The results showed that this recombinant peptide had an antibacterial effect on Staphylococcus aureus -p<0/0001-, but had no effect on methicillin-resistant Staphylococcus aureus. Heat resistant of the recombinant peptide also showed that 100 °C temperature for 40 minutes had no significant effect on the anti-bacterial properties of this protein -p<0/0001-. This protein showed no loss of activity after freeze drying process. The results obtained from this study proved the stable activity of natural peptides as well as antibacterial properties. This recombinant peptide can be used as an alternative to antibiotics or a therapeutic supplement to cure mastitis in dairy cows.
