Mother: My son contracted Pseudomonas at Prince George's Hospital Center last year

CHEVERLY, Md. - Prince George's Hospital Center shut down its neonatal intensive care unit Tuesday and transferred nine babies to another hospital after three of the infants tested positive for a dangerous bacteria known as Pseudomonas.

As of Wednesday, the source of the bacteria found in the NICU has still not been determined, but hospital officials said this type of bacteria is often found in water systems. This led the hospital to begin the disinfecting process of the plumbing that leads into the NICU on Wednesday.

FOX 5 spoke with a woman who said her adult son was treated at the hospital last year and caught the bacteria while at the facility.

"[On] May 31, my son got shot and he was rushed here and he contracted Pseudomonas," said Mecca Recio. "Not even the gunshot wounds kept him here in the hospital. The Pseudomonas kept my son sick for almost a year."

Recio said some of the symptoms her son faced were vomiting, high fever and "anything and everything that would make you internally sick in the stomach and in your blood system."

FOX 5 has confirmed the Maryland Department of Health and Mental Hygiene sent employees to the hospital on Wednesday to help in the effort to make sure the entire hospital is safe again.

The Washington Suburban Sanitary Commission said it conducted tests on a water sample collected at a nearby sampling station near the hospital last week and found no bacteria in the samples. WSSC tested another water sample from the same site on Wednesday and results are expected on the following day.
