Abstract:

Because of inappropriate use of antibiotics and prevalence of resistant bacteria, there is urgentneed for antibacterial drugs that have fewer side effects than antibiotics. Myrtus communis is amedicinal plant which had many uses in traditional medicine. In this study, ethanol leave extractof this plant is tested on Acinetobacter baumannii. In the case of antimicrobial evaluation ofplants, one of the effecting factors on effectiveness of the microbial inhibition is extractiontechniques. In the presents study, the antibacterial activity of the Ethanol, Methanol, andEthyl acetate extracts of M. communis plant was evaluated at seven different concentrationsby broth microdilution method. The results of this study showed that the antimicrobial effectof M. communis extract is concentration dependent. Different extracts were obtained by themaceration method. Extracts of the plant exhibited antibacterial activity at varied levels againstA. baumannii. Obtained results from our antibacterial experiments showed that all extracts haveanti-bacterial activity against tested bacterial isolates According to the results, the ethyl acetateextracted fraction showed the highest level of activity at a MIC 400 mg/ml for A. baumannii.The results of this study indicate that, different extracts had growth inhibitory effect on A.baumannii. Therefore this plant has the potential to be evaluated as an alternative or adjunct toantibiotics to treat Acinetobacter infections.

Antibacterial Effect Leaf Extract of Avicennia marina on Standard and Clinical Strains of Acinetobacter baumannii

Background: Acinetobacter baumannii is an opportunistic pathogen and a nosocomial infection agent. Antibiotic resistance in this organism results in serious health problem such as treatment failure and increased mortality. Mangrove plants, especially Avicennia marina, are a potential bioresource for new drugs as they have been used in traditional medicine. This study aimed to investigate antib...

Evaluation of the Antimicrobial Properties of the Essential Oil of Myrtus communis L. against Clinical Strains of Mycobacterium spp.

Mycobacterium tuberculosis is the etiological agent of tuberculosis. The World Health Organization has estimated that 8 million of people develop active TB every year and the situation is complicated by an increase of Mycobacterium tuberculosis strains resistant to drugs used in antitubercular therapy: MDR and XDR-TB. Myrtle leaf extracts, used as an antiseptic in Sardinian traditional medicine...

Isolation and antibacterial activity of acylphloroglucinols from Myrtus communis.

Isolation procedures of two new acylphloroglucinols, myrtucommulone-A and myrtucommulone-B, from Myrtus communis leaves are given. Myrtucommulone-A was highly antibacterial against gram-positive bacteria but was not active against gram negatives. The chemical relation to other acylphloroglucinols and the antibacterial activity of the compounds isolated are discussed.

Silver Nanocomposite Biosynthesis: Antibacterial Activity against Multidrug-Resistant Strains of Pseudomonas aeruginosa and Acinetobacter baumannii.

Bacterial resistance is an emerging public health issue that is disseminated worldwide. Silver nanocomposite can be an alternative strategy to avoid Gram-positive and Gram-negative bacteria growth, including multidrug-resistant strains. In the present study a silver nanocomposite was synthesized, using a new green chemistry process, by the addition of silver nitrate (1.10-3 mol·L-1) into a ferm...
