Relation of aerobiosis and ionic strength to the uptake of dihydrostreptomycin in Escherichia coli

Abstract

Aminoglycoside antibiotics exhibit a markedly reduced antibacterial activity under anaerobic conditions. Anaerobiosis or inhibitors of electron transport produced an extensive decrease in the uptake of dihydrostreptomycin in Escherichia coli K-12. Uptake of proline or putrescine were only slightly impaired under anaerobic conditions in the presence of glucose. Both the susceptibility to and the uptake of dihydrostreptomycin under anaerobic conditions were partially restored by addition of the alternative electron acceptor, nitrate. This stimulation required functional nitrate reductase activity. Abolition of uptake by 2,4-dinitrophenol under both aerobic and anaerobic conditions indicates that streptomycin uptake requires electron transport as well as a sufficient membrane potential. In addition, the initial rate of dihydrostreptomycin uptake was competitively and reversibly inhibited by added salts. The inhibition was relatively nonspecific with respect to the identity of salt added, being approximately dependent on the ionic strength. Although dihydrostreptomycin and polyamines mutually inhibited each other's uptake, several conditions (polyamine limitation, streptomycin uptake-deficient mutants) were found in which uptake of...Continue Reading

Allergy & Infectious Diseases

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.

Aminoglycosides (ASM)

Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside. Discover the latest research on aminoglycoside here.
