Forensic Microbiology Identifies Source of Major Hospital Infection: North America

Cause Of The Global Epidemic Of Clostridium Difficle Identified.  MNT--Medical News Today.  December 10, 2012.

Researchers from the Wellcome Trust Sanger Institute and the London School of Hygiene and Tropical Medicine have established a database for researchers to trace the genomic changes in C. difficile outbreaks.  They have traced C. difficile betwen 2002 and 2006 to two epidemic strains that emerged in North American and spread rapidly between hospitals around the world.  By using techniques of forensic microbiology researchers hope to trace the evolution of drug resistance in hospital and clinical settings.
