The metallo-β-lactamase IMP-1, which belongs to molecular class B (2), is clinically important because of its broad substrate specificity and its efficient hydrolysis of almost all of the β-lactam antibiotics, such as cephems, penicillins, and espe

The antibacterial interactions of temocillin with other beta-lactams were tested by checkerboard combination in Mueller-Hinton agar against 146 strains of members of the family Enterobacteriaceae, 35 Pseudomonas aeruginosa strains, and 35 Staphylococ

In contrast to currently marketed fluoroquinolones, which are zwitterionic, delafloxacin is an investigational fluoroquinolone with an anionic character that is highly active against Gram-positive bacteria. We have examined the effect of acidic pH on

VanA-type Staphylococcus aureus strain VRSA-7 was partially dependent on glycopeptides for growth. The vanA gene cluster, together with the erm (A) and the ant(9)-Ia resistance genes, was carried by the ca. 35- to 40-kb conjugative plasmid pIP848 pre

Class D β-lactamases are a group of structurally related active site serine enzymes that share a common ancestry with the high-molecular-weight class C penicillin-binding proteins (18). Class D β-lactamases usually exhibit a preference for penam su

Changes in bacterial ultrastructure after antibiotic exposure and during the postantibiotic effect (PAE) have been demonstrated by electron microscopy (EM). However, EM is qualitative and subject to individual interpretation. In contrast, flow cytome

The presence of a novel macrolide efflux system in streptococci was first described and firmly established in 1996 by Sutcliffe et al. (81). This system was phenotypically recognized and characterized to confer low-level resistance (MICs, 1 to 32 μg

Antibacterial effect and emergence of resistance to gemifloxacin and levofloxacin were studied in an in vitro pharmacokinetic model of infection. A panel of Streptococcus pneumoniae strains with known mechanisms of resistance were used; two strains h
