Of the proteins present in the egg albumin, ovalbumin, ovotransferrin and lysozyme have the most important bactericidal properties. However, such properties have not been reported for egg albumen of the sea turtle Lepidochelys olivacea. The objective of this study was to determine the bactericidal activity of egg white of L. olivacea at different concentrations. The results showed both a bactericidal effect on Gram-positive bacteria (Staphylococcus aureus, Staphylococcus saprophyticus and Micrococcus luteus) and Gram-negative bacteria (Klebsiella pneumoniae), as well as a proliferative effect on Gram-positive bacteria (S. aureus, Staphylococcus epidermidis and M. luteus) and Gram-negative (Escherichia coli, K. pneumoniae and Pasteurella multocida).

Key words: Reptile, Gram positive bacteria, Gram negative bacteria
