Background: This work evaluated the efficiency of common ultrasound stimulation (U.S.S) types on bacterial growth in vitro using clinically relevant conditions.Objective: To estimate different frequencies ultrasound bactericidal ability on bacteria in bacteria of Pseudomonas Aeruginosa. Methods: Six types of U.S.S (continuous wave, 7w/cm2, 20 KHz; continuous wave, 35w/0.8L, 40 KHz; continuous wave, 5w/cm2, 1.1 MHz; pulsed wave, 5w/cm2, 3.3 MHz; continuous wave, 5w/cm2, 3.3 MHz and continuous wave, 0.5w/cm2, 3.5 MHz) were applied to a separate set of culture plates containing Pseudomonas aeruginosa for 10 minutes at room temperature on four sample sets to inhibit bacterial growth. After US.S treatment, the zone of inhibition at the US probe location was measured.Results: Zone of inhibition measurements demonstrated a significant inhibitory effect for continuous wave US.S of 5w/cm2, 1.1 MHz; pulsed wave US.S of 5w/cm2, 3.3 MHz; and continuous wave US.S of 5w/cm2, 3.3 MHz (p < 0.05), but not for continuous wave US.S of 7w/cm2, 20 KHz; continuous wave US.S of 35w/0.8L, 40 KHz; and continuous wave US.S of 0.5w/cm2, 3.5 MHz.Conclusion: The data suggest that for infected wounds, continuous wave US.S of 5w/cm2 and 1.1 MHz; pulsed wave US.S of 5w/cm2 and 3.3 MHz; and continuous wave US.S of 5w/cm2 and 3.3 MHz ultrasound treatments may have an initial bacterial inhibitory effect, which does not significantly change with subsequent treatments.

A comparison of four electrical stimulation types on Staphylococcus aureus growth in vitro.

We evaluated the efficacy of common electrical stimulation (ES) types on bacterial growth in vitro using clinically relevant conditions. Four types of ES--continuous microamperage direct current (microADC), high-voltage pulsed current (HVPC), low-voltage monophasic milliamperage pulsed current (LVMmAPC), and low-voltage biphasic milliamperage pulsed current (LVBmAPC)--were each applied to a sep...

The Effect of Magnetic Fe3O4 Nanoparticles on the Growth of Genetically Manipulated Bacterium, Pseudomonas aeruginosa (PTSOX4)

Background: Magnetite (Fe3O4) nanoparticles are currently one of the important and acceptable magnetic nanoparticles for biomedical applications. To use magnetite nanoparticles for bacteria cell separation, the surface of nanoparticles would be modified for immobilizing of nanoparticles on the surface of bacteria. Functionalization of magnetite nanoparticles is performed by different s...

In vitro comparison of effects of extracts of Ailanthus altissima and Salvia nemorosa on Pseudomonas aeruginosa, Staphylococcus aureus and Proteus vulgaris

Introduction: Some plants have antiseptic roles and often do not cause harm to humans or animals. In this study, we try to introduce plants to disinfect spaces and surfaces contaminated with bacteria so that toxic substance does not remain in the environment. Materials and Methods: Ailanthus altissima and Salvia nemorosa extracts were used against lyophilized Pseudomonas aeruginosa, Staphyloco...
