Selection of gentamicin-resistant variants of Pseudomonas aeruginosa in the rat cornea

Journal of Ocular Pharmacology
P R Badenoch, D J Coster

Abstract

Pseudomonas aeruginosa often persists in ocular infections despite intensive antimicrobial therapy. In this study, gentamicin-resistant small colony variants (SCV) were selected in vitro from three gentamicin-susceptible Pseudomonas isolates by incubation with antibiotic. In the rat cornea, SCV were selected from two of these strains by administration of gentamicin either topically or intravenously. The selection of resistant variants may be a contributing factor in the persistence and reactivation frequently associated with ocular Pseudomonas infections.

Antimicrobial Resistance

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

Antifungals (ASM)

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

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.

Aminoglycosides

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.
