[ 1 ] - In Vitro Antibacterial Activity of Several Plant Extracts and Oils against Some Gram-Negative Bacteria
Background: Medicinal plants are considered new resources for producing agents that could act as alternatives to antibiotics in the treatment of antibiotic-resistant bacteria. The aim of this study was to evaluate the antibacterial activity of 28 plant extracts and oils against four Gram-negative bacterial species.Methods: Experimental, in vitro, evaluation of the activities of 28 plant extract...
[ 2 ] - Inactivation of Gram-Negative Bacteria by Low-Pressure RF Remote Plasma Excited in N2-O2 Mixture and SF6 Gases
The role of low-pressure RF plasma in the inactivation of Escherichia coli O157, Klebsiella pneumoniae, Proteus mirabilis, and Enterobacter sakazakii using N2-O2 and SF6 gases was assessed. 1×109 colony-forming units (CFUs) of each bacterial isolate were placed on three polymer foils. The effects of pressure, power, distance from the source, and exposure time to plasma gases were optimized. The...
[ 3 ] - Effect of Medium pH on Antibiotic Activity against Syrian Brucella spp. Isolates
Background: Brucellosis is an endemic zoonosis in Syria, affecting large numbers of animals. There are an increasing number of cases in humans. Brucella is a facultative intracellular pathogen, a small, non-motile, Gram-negative coccobacillus, which causes abortion in domestic animals and a febrile illness in humans. Methods: One hundred isolates collected from different Syrian regions were con...
[ 4 ] - The Antibacterial Activity of Selected Labiatae (Lamiaceae) Essential Oils against Brucella melitensis
Background: Brucellosis, a zoonosis caused by four species of brucella, has a high morbidity. The major cause of brucellosis worldwide is brucella melitensis. Medicinal plants are considered as new antibacterial sources that could replace conventional antibiotics in the treatment of antibiotic-resistant bacteria. The aim of this study was to evaluate the efficacy of some native plants, alone an...
[ 5 ] - Antibacterial Activity of Thymus Syriacus Boiss Essential Oil and Its Components against Some Syrian Gram-Negative Bacteria Isolates
Background: Despite the medical discoveries of different medicines and advanced ways of treatment, statistics have shown that the number of patients is increasing. This may be due to chemical drugs used in healthcare, agriculture, and diets. This soaring demand in medicines urges us to look for natural sources such as aromatic plants and essential oils, which are rich in efficient compounds. ...
[ 6 ] - In Vitro Antibacterial Effects of Five Volatile Oil Ex-tracts Against Intramacrophage Brucella Abortus 544
Background: Brucella abortus is a gram-negative facultative intracellular bacterium that can cause a highly contagious disease in sheep, goats, cattle and one-humped camels. It is responsible for one of the most important zoonosis in human. The aim of this study was to evaluate the role of Mentha piperita, Origanum majorana, Citrus lemon, Cinnamomum verum and Myristica fragrans essential volati...
