Merck & Co Inc said on Monday it would buy Cubist Pharmaceuticals Inc in a deal valued at $9.5 billion, giving the major drugmaker an entry into the market for drugs that target so-called superbugs.

Merck (MRK) and British rival AstraZeneca Plc have turned their attention to newer kinds of antibiotics that attack superbugs — strains of bacteria that are resistant to several types of antibiotics — after the 2013 threat report from the U.S. Centers for Disease Control and Prevention.

The CDC estimated that more than 2 million people in the United States are sickened every year by such infections, with at least 23,000 dying as a result.

Cubist’s lead drug, Ceftolozane/Tazobactamis, is widely expected to win marketing approval from the U.S. Food and Drug Administration later this month as a treatment for complicated urinary tract infections.

Merck will pay $102 per share for Cubist, a premium of 37 percent to the Lexington, Massachussetts-based company’s closing share price of $74.36 on Friday.

The deal includes assumption of $1.1 billion in debt.
