The Clinical Microbiology Laboratories at the Veterinary Hospital of the University of Pennsylvania comprise five individual laboratories, namely, Ryan Clinical Microbiology (CML-Ryan), New Bolton Center Clinical Microbiology (CML-NBC), the Salmonella Reference Center (SRC), Molecular Testing Laboratory (MTL) and the Salmonella Egg Testing (PEQAP) lab. The New Bolton Center Labs belong to the Pennsylvania Animal Diagnostic Laboratory System (PADLS). All labs perform diagnostic testing and each lab also has a research component.

Salmonella, Staphylococcus, antibiotic resistance, molecular diagnostics, pulsed-field gel electrophoresis (PFGE)

Research includes the development, validation and verification of molecular diagnostic assays, for the diagnosis of infectious disease in animals. The lab focuses primarily on discriminatory molecular typing methods to study the epidemiology of methicillin-resistant staphylococci isolated from companion animals and their potential to be transmitted to humans. Similar molecular methods are used to characterize Salmonella strains isolated from food animals. We also study the mechanisms of transferable and non-transferable antimicrobial resistance of Salmonella and other Enterobacteriaceae in natural populations.
