Fusidic acid: new opportunities with an old antibiotic

Canadian Medical Association Journal
J D Anderson

Abstract

The extensive foreign experience with fusidic acid prior to its belated introduction to Canada is reviewed. Fusidic acid is a steroid antibiotic with minimal toxic and hormonal effects that is mainly excreted through the liver. It has a predominantly bactericidal action and does not shown cross-resistance with other antibiotics. Since organisms resistant to this drug form easily in vitro when exposed to low concentrations, complementary treatment with another antibiotic may be required in some clinical situations. Although fusidic acid is active in vitro against a number of organisms, to date it has mainly been used to treat serious infections due to Staphylococcus aureus. The agent appears to be particularly valuable in the treatment of bone and joint infections and in pediatric practice. Fusidic acid will soon be available in Canada for both oral and intravenous administration. Attainable antibiotic levels in many tissues and body fluids greatly exceed the minimum inhibitory concentrations.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.

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.
