Herman Bustamente filed suit against the United States for damages pursuant to the Federal Tort Claims Act (FTCA), 28 U.S.C. §§ 2671-80, alleging that he received negligent medical treatment at the New Orleans Veterans Administration Medical Center. He alleges that he contracted herpes from receiving blood infected with the virus during heart surgery at the hospital in 1996. Bustamente contends that the hospital was negligent based upon the doctrine of res ipsa loquitur. Bustamente appeals the district court’s grant of summary judgment to the Government.

We review a grant of summary judgment de novo, using the same standard applicable in the district court. Melton v. Teachers Ins. & Annuity Ass’n of America, 114 F.3d 557, 559 (5th Cir. 1997). Under the FTCA, the United States is hable for its torts if a private person would be hable for the same act or omission under local laws. 28 U.S.C. §§ 1346(b), 2674; *427 see Tindall v. United States, 901 F.2d 53, 55 (5th Cir. 1990). Because the alleged medical malpractice in this case occurred in Louisiana, Louisiana law controls. See Tindall, 901 F.2d at 55.

The only evidence offered by Bustamente as proof of the hospital’s negligence are medical records from his treating physicians, and those records do not support his allegation that he contracted herpes from a blood transfusion. Consequently, Bustamente has failed to carry his burden of proving the hospital’s negligence. See Boutte v. Jefferson Parish Hospital Service District No. 1, 807 So.2d 895, 898 (La.App. 5 Cir.), writ denied, 813 So.2d 1093 (La. 2002).

Bustamente’s argument regarding res ipsa loquitur need not be considered because it is raised for the first time in his reply brief. See Cinel v. Connick, 15 F.3d 1338, 1345 (5th Cir. 1994). Even if the res ipsa loquitur theory were addressed, however, it would be found unconvincing. Bustamente’s own evidence shows that the blood transfusion was not the probable cause of his infection and that there were other equally plausible explanations for his condition. See Cangelosi v. Our Lady of the Lake Regional Medical Center, 564 So.2d 654, 660 (La. 1990).

Accordingly, the judgment of the district court is hereby AFFIRMED.
