The National Microbiology Laboratory (NML) is located in the Canadian Science Centre for Human and Animal Health in Winnipeg, Manitoba, Canada. This modern state-of-the-art facility houses the NML's Biological Safety Level 4 (BSL-4) containment laboratory, currently Canada's only BSL-4 laboratory. As a maximum containment facility, the NML deals with the most serious human and animal pathogens and diseases, such as SARS, Ebola and Lassa fever. The laboratory has played a pivotal role in testing and identifying specimens from suspected victims of the 2009 swine flu.
