Abstract excerpt

Listeriosis is a severe foodborne infection and associated with high mortality. Treatment is based on ampicillin, amoxicillin or penicillin, often combined with gentamicin, but meropenem is also used occasionally. β-lactam resistant Listeria monocytogenes isolates are infrequently described but the mechanism of resistance is not known. A clinical L. monocytogenes isolate with reduced β-lactam susceptibility was...
