Enteric Diseases Laboratory Branch

National Botulism Laboratory Team

The National Botulism Laboratory Team (NBLT) maintains CDC expertise for laboratory investigations of botulism, and provides training to U.S. and international public health laboratories. NBLT outbreak activities include detection and serotyping of botulinum neurotoxin, and the isolation and identification of botulinum-toxin-producing Clostridia. NBLT also develops and validates new detection and identification methods for the enhancement of the U.S. response to bioterrorism events involving botulinum toxin.
