Bacterial resistance to aminoglycoside antibiotics occurs by a variety of mechanisms. In
clinical situations the most common mechanism is plasmid-determined modification of the …

A 37 but not 26 degrees C virulent Yersinia pestis is known to require at least 2.5 mM Ca2+
for growth; this requirement is potentiated by Mg2+. After shift of log-phase cells (doubling …

Mutations conferring resistance to low levels of kanamycin in Escherichia coli have been
mapped at 3 locations: the unc locus (min. 83), a locus we have designated, kanA (min. 72) …

Mutants resistant to the 2-deoxystreptamine aminoglycosides hygromycin B and gentamicin
were analyzed biochemically and genetically. In hygromycin B-resistant strains, ribosomal …

Aminoglycoside adaptive resistance was characterized in one reference strain and four
clinical isolates of Pseudomonas aeruginosa. Adaptive resistance was initiated with a 2-h …

Zwittermicin A is a novel aminopolyol antibiotic that represents a new structural class of
antibiotic and has diverse biological activities, including the suppression of plant disease …

A mutation affecting the intrinsic membrane portion (BFo) of the ATP synthetase complex is
described. The phenotype is different from previously reported BFo mutants. This mutation …

The relative impermeability of the cytoplasmic membrane to protons, and at least some other
cations, may critically relate to the energization of a variety of processes, including ATP …

Gentamicin and neomycin-resistant mutants of Escherichia coli K-12 were isolated some of
which were resistant to nitrofurans, chlorate, PI and λ bacterio-phages as well as to all …
