Environmental Mutagen Society Meeting—October 15-19
NCTR scientists presented their research results at the 42nd Annual Meeting of the Environmental Mutagen Society (EMS) held in Montreal, Canada.  The topics of their presentations included:

• Cancer biomarker methodology developed at NCTR
• New method to detect mutations induced by drugs or environmental chemicals

The EMS promotes “critical scientific knowledge and research into the causes and consequences of damage to the genome and epigenome in order to inform and support national and international efforts to ensure a healthy, sustainable environment for future generations.”

Fluoroquinolone-Resistant Salmonella Schwarzengrund from Imported Foods
NCTR scientists have identified fluoroquinolone-resistant strains of Salmonella enterica serovar Schwarzengrund and characterized the antimicrobial-resistance determinants in isolates collected by the FDA Pacific Regional Laboratory from food imported to the USA.  Salmonella Schwarzengrund is spreading internationally and is one of few serovars causing invasive salmonellosis.  With limited numbers of antibiotics available for treatment, antibiotic resistance may increase the risk of invasive salmonellosis, which has a high hospitalization rate.  A manuscript describing the results of this study was recently accepted for publication in the Journal of Antimicrobial Chemotherapy (DOI: 10.1093/jac/dkr414).
