GREENVILLE, S.C. - Greenville Health System says it found bacteria in its hospital that caused infections in 14 surgical patients over the past several months.

Hospital epidemiologist Dr. Bill Kelly says one patient who was infected died, but the primary cause of death was an underlying disease.

The hospital says the first patient with the atypical mycobacterium was detected in March 2014. Doctors say it took months for some cases to show up because the organism has a long incubation period.

Kelly says the hospital has identified the piece of equipment that likely caused the infections and pulled it out of use along with other equipment involved in the surgeries.

The hospital says the people who tested positive for the bacteria are being notified.
