Exhibit 99.1

Oragenics, Inc. Changes Name to ONI Biopharma Inc.

FOR IMMEDIATE RELEASE

ALACHUA, FL (May13, 2008) – Oragenics, Inc. (AMEX:ONI) announced today that its Board of Directors approved the use of the Company’s new name of ONI BioPharma Inc. The Company recently registered in the State of Florida to do business as “ONI BioPharma Inc.” The Company will refer to itself as ONI BioPharma from this point forward and expects to seek to obtain shareholder approval to amend its articles of incorporation in order to formally change its name from Oragenics, Inc. to ONI BioPharma Inc. in connection with the next annual meeting of shareholders. The Company believes that the new name more accurately reflects the broad range of scientific platforms and products that the Company has under development through the efforts of its scientific team, headed by Dr. Jeffrey Hillman, our Chief Scientific Officer.

Our Chairman, Richard T. Welch, stated that, “although we remain committed to oral health, the Company is active in the development of novel antibiotics and diagnostics as well and the new ‘doing business name,’ ONI BioPharma, conveys a better sense of a company that is active in other areas, in particular the infectious diseases arena.”

Notwithstanding our doing business as ONI BioPharma Inc, and our expected future formal name change, our common stock will continue to trade under the stock symbol “ONI” on the American Stock Exchange.
