Plasma is a neutral ionized gas, which is composed of particles including free electrons, radicals, positive and negative ions, quanta of electromagnetic radiation, excited and non-excited molecules. The plasma needle (NBS) is a type of nonthermal atmospheric capacitive coupled glow discharge; it has a single electrode configuration and is operated in a noble gas. Important properties of this type of plasma are that it operates near room temperature and atmospheric pressure, and allows treatment of irregular surfaces and has a small penetration depth. Opportunistic bacterial pathogens are ubiquitous inhabitants of both the environment and the human body, causing serious infections in immune compromised patients. Pseudomonas aeruginosa is a major cause of nosocomial infections, as it shows a remarkable capacity to resist antibiotics. Physical treatments NBS is an alternative approach to fight opportunistic infections when the effectiveness of chemical agents is weak due to a natural pathogen. The plasma needle is capable of bacterial decontamination and of localized cell removal without causing necrosis to the treated or the neighboring cells. In addition, it has a relatively simple design. The metal pin or needle syringe used as high voltage electrode. Noble gas flows through the electrode at a different rate of L/min. The flow rate is regulated by a mass flow controller. Due to advantages presented in terms of cost, environmental compliance and ease of processing, this study aimed to decrease pathogenicity of P. aeruginosa by applying an alternative method represented by needle plasma at different treatment time as a bactericidal effectiveness tool.
