The health of former Indonesian dictator Suharto deteriorated Wednesday, with a potentially lethal infection spreading through his body, his doctors said.

Suharto, who brutally ruled the nation for 32 years until being toppled a decade ago, has developed digestive trouble and severe pneumonia, said Dr. Joko Raharjo, a member of the presidential medical team.

"We are trying hard to find and detect the bacteria and treat him with proper antibiotics, but we cannot guarantee it will be successful," he told reporters.

Suharto, who was rushed to a hospital with anemia and a dangerously low heart rate Jan. 4, has suffered multiple organ failure and is on a ventilator, dialysis machine and is being fed through a tube.
