A. baumannii, which is found in water and soil and resistant to many types of antibiotics, surfaces occasionally in hospitals, often spread among patients in intensive care units.

The injured soldiers are being treated with a spectrum of drugs and are expected to recover from their infections.

ATLANTA (Reuters) - An unexpectedly high number of U.S. soldiers injured in the Middle East and Afghanistan are testing positive for a rare, hard-to-treat blood infection in military hospitals, Army doctors reported on Thursday.

A total of 102 soldiers were found to be infected with the bacteria Acinetobacter baumannii. The infections occurred among soldiers at Walter Reed Army Medical Center in Washington, Landstuhl Regional Medical Center in Germany and three other sites between Jan. 1, 2002, and Aug. 31, 2004.

Although it was not known where the soldiers contracted the infections, the Army said the recent surge highlighted a need to improve infection control in military hospitals.

Eighty-five of the bloodstream infections occurred among soldiers serving in Iraq, the area around Kuwait and Afghanistan, the U.S. Army said in a report published on Thursday by the Centers for Disease Control and Prevention.

Military hospitals typically see about one case per year.
