Effect of Plant Extracts and Volatile Oils on Antibiotic Resistant Bacterial Isolates Causing Infections in Various Parts of the Body

Background: In order to cure newly emerging human illnesses, plant extracts and volatile oils with antimicrobial action against bacteria were employed. This is because medically important plants have substantial phytochemical classes with therapeutic characteristics. Objectives: This study aims to enhance antibiotic efficacy by combining substitute natural compounds to eradicate resistant bacteria, reducing disease transmission and making treatment difficult. Methodology: The investigation involved 72 clinical samples, including blood, abscesses, wounds, and bedsores. Clinical isolates were identified using Bergey's Manual of Determinative Bacteriology, and antibiotic sensitivity was assessed using NCCLS guidelines. SDS PAGE profiles were used to analyze cell protein profiles. Results: The majority of clinical bacterial isolates (52.77%) are Staphylococcus aureus, which is followed by Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, and Staphylococcus epidermidis. Norfloxacin has a 59.72% sensitivity against clinical bacterial isolates, followed by amikacin and chloramphenicol, whereas penicillin and cefoperazone have no effect on these isolates. The difference between norfloxacin's MIC and MBC was highly significant (p < 0.01 HS). The most potent antibacterial action was shown by clove extract and clove volatile oil. Clove extract and norfloxacin together exhibit synergistic suppression of clinical bacterial isolates. Protein bands of the bacteria before and after treatment were different for the control and norfloxacin clove extract-stressed bacterial isolates. Conclusions: This study investigates antibacterial properties of medicinal plants, aiming to prevent drug resistance and develop strategies for future antibiotic synthesis through structural clarification.
