objective: this study designed to test the antibacterial potency of enrofloxacin (enr) and essential oils from zataria multiflora boiss (zeo) and trachyspermum copticum (teo)on aeromonas hydrophila. material and methods: the antibacterial potency of test compounds was determined by several methods including the inhibition zone diameter determination, microbroth dilution method and colorimetric ...

To prevent and treat diseases caused by the spread of microbes, humans have invented all sorts of effective antimicrobial substances. The most widely used antimicrobial substance is antibiotics. However, misuse of antibiotics can generate various negative effects, bacterial resistance, decreased immunity, and internal flora imbalance which can lead to endogenous infection. In addition, existing...

Essential oils (EOs) have been long recognized for their antibacterial, antifungal, antiviral, insecticidal and antioxidant properties. They are widely used in medicine and the food industry for these purposes. The increased interest in alternative natural substances is driving the research community to find new uses and applications of these substances. EOs and their components show promising ...

Pseudomonas aurantiaca S-1 can serve as a natural source of pesticides towards phytopathogens like Fusarium oxysporum P1 and Pseudomonas syringae pv. glycinea BIM B-280. The largest pool of produced antimicrobial compounds was found in four days-old spent culture supernatant. At least two groups of bioactive substances were identified, one responsible for the antibacterial activity and the othe...

Plants used in traditional medicine are potential sources of new biologically active compounds many of them with antibacterial and antifungal activity. Plants can serve as a source of model compounds for synthetic or semi synthetic structure modification (Balandrin et al., 1993). Potential natural and synthetic substances with biocidal activity are considered candidates for developing new drugs...

Interest is arising in the possible use of higher plants as the source of naturally occurring antibiotic substances. The use of higher plants in the treatment of disease is as old as the art of healing itself. Isaiah of Biblical times suggested that a plaster of figs be placed on boils as a treatment of this form of infection. Hyssop and cedarwood were used in the cleansing of lepers. The Orien...

the edible mushrooms (basidomycetes) have high nutritional value, promote the immune system, and as a source of natural antimicrobial substances have been used to cure bacterial infections since ancient times.various kinds of proteins with several biological activities are produced by mushrooms. in this research, in order to evaluate antibacterial activity of edible mushrooms, we isolated prote...
