Abstract

The effect of Cd2+ on aerobic and anaerobic growth was studied in the Cd2+-resistant Staphylococcus aureus 17810R which harbours the cadA and cadB markers on a penicillinase plasmid pII17810. Also the effect of Cd2+ on growth of the plasmidless strain 17810S, sensitive to Cd2+ was investigated. The results indicate that under all growth conditions the Cd2+-resistant S. aureus 17810R is protected against Cd2+ toxicity up to 100 microM Cd2+ by the 2H+/Cd2+ antiporter, the product of the cadA gene. Energetics of growth of both strains under various conditions is also discussed.

Antimicrobial Resistance

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