Effect of sublethal heat on the metabolic activity of Staphylococcus aureus.

Cells of Staphylococcus aureus MF-31 which have been heat-injured at 52 C have an altered metabolic activity. Analyses of whole-cell preparations by means of the Thunberg technique and Warburg manometry showed decreased dehydrogenase activity and oxygen uptake on a variety of substrates. In cell-free extracts prepared from injured cells, it was demonstrated that the specific activity of fructos...

Repair and enterotoxin synthesis by Staphylococcus aureus after thermal shock.

To study repair and enterotoxin synthesis, four staphylococcal strains (FRI-100, FRI-137, FRI-472, and S6) were subjected to sublethal heat treatment, transferred to four liquid repair media (1% powdered skim milk in distilled water, complex medium, M9 minimal salt medium, and saline solution), and then incubated at different temperatures. Powdered skim milk proved to be the most efficient medi...

Thermotolerance and Human Performance: Role of Heat Shock Proteins

Introduction Thermotolerance (intrinsic and acquired) is the ability of the body and its cellular structures to withstand severe destructive heat stress. Acquired thermotolerance [adaptive] (ATT) is induced by pre-exposure to elevated but non-lethal temperatures and leads to enhanced cellular protection, synthesis of stress and heat shock proteins (HSPs), and reduced risk from subsequent heat i...

Thermotolerance and profile of protein synthesis in murine bone marrow cells after heat shock.

In this study, we first investigated the survival of colony-forming units, granulocyte and macrophage (CFU-GM), after a single heat treatment. We then examined the induction, development, and decay of thermotolerance in CFU-GM. Finally, we analyzed the profiles of protein synthesis in the total murine bone marrow population during the development of thermotolerance. Several salient features eme...

Sublethal vancomycin-induced ROS mediating antibiotic resistance in Staphylococcus aureus

Staphylococcus aureus is the leading cause of many human infectious diseases. Besides infectious dangers, S. aureus is well-known for the quickly developed drug resistance. Although great efforts have been made, mechanisms underlying the antibiotic effects of S. aureus are still not well clarified. Recently, reports have shown that oxidative stress connects with bactericidal antibiotics [Dwyer ...
