Diagnostic Bacteriology Laboratory

The Diagnostic Bacteriology Laboratory (DBL) provides diagnostic assistance for bacterial and protozoal diseases by conducting serologic testing for the presence of antibodies to pathogens; isolating, identifying, and genotyping bacteria; producing reagents needed for diagnostic testing; administering proficiency tests for selected diseases; and providing diagnostic training.

The DBL is a World Organization for Animal Health (OIE) reference laboratory for leptospirosis, contagious equine metritis, and anthrax.

The major functions of the DBL include import testing for equine piroplasmosis, dourine, and glanders; Salmonella serotyping; cultures for the diagnosis of bovine tuberculosis and brucellosis; brucellosis reagent production; Mycobacterium patatuberculosis (Johne's Disease) serology and culture; and Leptospira serology.

The laboratory also maintains the brucellosis, bovine tuberculosis, Johne's Disease, and National Animal Health Monitoring System serum banks and Johne's Disease culture bank.
