RARE PLASMID-MEDIATED AMPC BETA-LACTAMASE DHA-1 LOCATED ON EASY MOBILIZED IS26-RELATED GENETIC ELEMENT DETECTED IN ESCHERICHIA COLI FROM LIVESTOCK AND FOOD IN GERMANY

Rare Plasmid-Mediated AmpC Beta-Lactamase DHA-1 Located on Easy Mobilized IS26-Related Genetic Element Detected in Escherichia coli from Livestock and Food in Germany

AmpC beta-lactamases cause resistance to third-generation cephalosporins, including beta-lactamase inhibitors.In Escherichia coli from the German food production chain, the majority of AmpC beta-lactamase activity can be attributed to plasmid-mediated CMY-2 or overproduction of chromosomal AmpC beta-lactamase, but occasionally other enzymes like DH

Rapid and persistent selection of the K103N mutation as a majority quasispecies in a HIV1-patient exposed to efavirenz for three weeks: a case report and review of the literature

Abstract Introduction Selection of the K103N mutation is associated with moderately reduced in vitro fitness of HIV.Strains bearing K103N in vivo tend to persist, even in the absence of additional drug pressure, Adidas Cotton T-Shirt as minority quasispecies, often undetectable in genotyping resistance testing assays, performed at standard conditio
