Officials in Kagoshima Prefecture, southwestern Japan, say 8 inpatients have died at Kagoshima University Hospital from a suspected in-hospital infection.
The officials say a bacterium resistant to most antibiotics has been detected from multiple patients at the hospital in Kagoshima city.
Prefectural and Kagoshima city government officials say that since April last year 5 patients have been infected with the multidrug-resistant Acinetobacter. A similar strain of bacterium was detected in 10 other patients.
The officials have not released the age, sex or time of death of the 8 patients. They say the infections may have spread mainly in intensive-care units.
Hospital officials are scheduled to hold a news conference on Friday on the matter.
