## Abstract

The method of treating a bacterial infection using colostrum includes administering an effective amount of colostrum to a subject in need thereof. The infection can be caused by G+ or G− bacteria. The colostrum administered may be selected from the group consisting of bovine colostrum, camel colostrum, and a mixture of bovine colostrum and camel colostrum. The bacterial infection may be selected from the group consisting of Staphylococcus aureus subs. aureus Rosenbach, Escherichia coli, Pseudomonas aeruginosa, and Methicillin-resistant Staphylococcus aureus. A colostrum composition can include a mixture of bone and camel colostrum and a pharmaceutically acceptable carrier.
