Pseudomonas infections are very hard to treat in immunocompromised patients, in the post operational and other hospitalization related conditions and are responsible for high number of deaths. Thus Pseudomonas can be very notorious opportunistic pathogen. The major problem associated with chronic P. aeruginosa infections is the development of antibiotic resistance due to long continuous treatment durations in which the resistant mutants start to accumulate. Recent understandings regarding the development of antibiotic resistance have added a new dimension of hypermutator strains which have comparatively high rates of mutations then wild type strains. In Ayurveda, many plants and plant extracts have been widely used for treatment of diseases which may be due to bacterial, fungal or viral pathogen or due to imbalance in the body’s various systems. Modulation of immune response to alleviate disease has been one of the ways practiced in ayurveda including others such as re-establishing the imbalance in the body, lifestyle changes, and diet. The plants extracts used are seeds of Moringa oleifera, Nigella sativa, Vernonia anthelmintica, fruit of Terminalia chebula and root bark of Terminalia bellerica. These plant extracts have been shown to be effective as an antibacterial agent specifically against P. aeruginosa. The plant extracts used in this study are easily available and is being used in normal day-to-day life for various purpose and also have been proven to be effective medicine in Ayurveda.

Zusammenfassung der Kapitel (Chapter Summaries)
Chapter 1: Introduction & Review of Literature: This chapter introduces Pseudomonas aeruginosa, a Gram-negative bacterium commonly found in various environments, including soil, water, and plants. It discusses P. aeruginosa's characteristics, emphasizing its remarkable adaptability and ability to thrive in diverse conditions, including harsh environments such as diesel fuel. The chapter details its classification within the Gamma Proteobacteria, its metabolic capabilities, and its emergence as a significant opportunistic human pathogen, particularly in nosocomial settings. It highlights the bacterium's virulence factors, mechanisms of infection, and the complexities of treating infections due to its propensity to develop antibiotic resistance. The review delves into the current and novel therapeutic approaches, including the potential of plant extracts, while acknowledging the drawbacks of existing treatments. The section on antibiotic resistance extensively covers the development of hypermutator strains, emphasizing the significant challenge posed by these highly resistant variants to current antimicrobial therapies. This chapter sets the stage for the rest of the work by providing a comprehensive background on P. aeruginosa and the challenges associated with its treatment.
Chapter 2: Materials & Methods: This chapter outlines the methodologies employed in the research. It details the experimental design, including both in vivo (Phase I) and in vitro (Phase II) studies. While specifics are not provided here, the chapter lays the foundation for understanding the approach taken to investigate the research questions posed in the introduction. The description would likely include details on participant selection (for in vivo studies), sample preparation and handling, specific laboratory techniques, and statistical analyses performed to evaluate the data obtained from the experiments.
