Montreal's Maisonneuve-Rosemont Hospital has been working on the cure of a Clostridium difficile outbreak, which has infected a number of people and has caused more than 300 deaths, so far.

C. difficile causes intense diarrhea, fever and abdominal pain and is regarded as the most dangerous bacterial superbug confronting North American hospitals in the past decade.

CBC has gained the information from the internal documents, accessing it through information laws.

The hospital claims that the outbreak is resultant of the overcrowded emergency rooms and improper sterilization. It has admitted that it has been battling with the outbreak from the last 6 months.

"For me, a crisis is something we don't see coming. In this case, it's the opposite. This is something we were working on", said Francis Methot, Hospital Director.

The hospital shared that the infection rates were higher in 2009 than in 2006 and 2007. As reported in the beginning of this month, C. difficile infection rate has dipped by 50%.

The Health officials suggest that regular hand-washing and other measures inspired by the swine flu outbreak have contributed in curbing the spread of C. difficile.
