Standard & Poor's said Monday drug developer Wyeth and medical waste management company Stericycle Inc. will replace Anheuser-Busch Cos. Inc. on several indices.

Madison, N.J.-based Wyeth will replace Anheuser-Busch on the S&P 100 index and Lake Forest, Ill.-based Stericycle will replace Anheuser-Busch in the S&P 500 index.

Meanwhile, Thomasville, Ga.-based Flowers Foods Inc. is taking Stericycle's place in the S&P MidCap 400, while San Francisco-based Diamond Foods Inc. will replace Flowers Foods in the S&P SmallCap 600.

S&P has yet to announce the effective date of the changes.

Additionally, Carlsbad, Calif.-based Life Technologies Corp., which will be the new name of the combined Applied Biosystems Inc. and Invitrogen Corp., will replace Applied Biosystems in the S&P 500. Hercules, Calif.-based Bio-Rad Laboratories Inc. will replace Invitrogen in the S&P MidCap 400.

Those changes are effective at the close of trading Nov. 21.
