Enterohemorrhagic Escherichia coli O157:H7 (EHEC) has caused foodborne outbreaks worldwide and the bacterium forms antimicrobial-tolerant biofilms. We investigated the abilities of various plant essential oils and their components to inhibit biofilm formation by EHEC. Bay, clove, pimento berry oils and their major common constituent eugenol at 0.005% (v/v) were found to markedly inhibit EHEC bi...

Antifungal activity of essential oils (EOs) of Zataria multiflora (thyme) and Syzygium aromaticum (clove) against Aspergillus flavus growth and aflatoxin B1 production was studied in potato dextrose agar (PDA) and potato dextrose broth (PDB), as well as in Iranian white cheese as a food model. The results showed that the inhibitory potential of EOs in the PDB medium is more than PDA medium. Clo...

Objective: Results obtained from literature reviews and human studies have shown the analgesic effects of clove plant in toothache. The present work was undertaken in order to investigate the possible analgesic effect of clove oil in mice. Materials and Methods: Fifty mice were divided into 5 groups: 1) Saline; 2) Essential oil (Ess) 2%, 3) Ess 5%, 4) Ess10% and 5) Ess 20%. The hot plate test (...

  There is a few available information about the effect of anesthetics, specially electroanesthesia on immune parameters in fish. In the present work, two anesthetics, MS222 (50 ppm), clove oil (25 ppm), and electroanesthesia were tested in rainbow trout (Oncorhynchus mykiss) in narcosis stage. The results showed, clove oil and electroanesthesia increase the lysozyme activity 24 h after anesthe...

This paper discusses the application of the dynamic method to measure the solubility in pseudo-ternary systems formed by vegetable raw materials (cellulosic structure+solute) and CO2. For aromatic, medicinal, and spice plants, the soluble portion of the solid is formed of essential oils, oleoresins, pigments, and various substances from several other classes of organic compounds. The experiment...

Determination of clove (Eugenia caryophyllata) essential oil and comparison its antibacterial properties with some conventional antibiotics

The ethanol extracts of clove (Eugenia caryophyllus Bullock & Harrison) and sweet flag (Acorus calamus Linn.) were investigated for their antifungal activity in comparison with eugenol and amphotericin B (AmB) by using the National Committee for Clinical Laboratory Standards (NCCLs) M27-P broth microdilution method. Two medicinal plant extracts, eugenol and amphotericin B were used to determine...

Vector repellent is one element in the prevention of vector-borne diseases. Families that neglect protecting their children against vectors risk their children contracting illnesses such as West Nile virus, eastern equine encephalitis, Lyme disease, malaria, dengue hemorrhagic fever, yellow fever, babesiosis, Crimean-Congo hemorrhagic fever, Rocky Mountain spotted fever, Southern tick-associate...

Effect of premedication with buprenorphine (BP) on efficacy and safety of tribromoethanol (TBE) - induced anaesthesia was evaluated and compared with anaesthesia induced by ketamine (K) and xylazine (X) combination in rats undergoing ovariectomy. Fifteen Sprague -Dawley rats (mean weight 246.5 ± 13.1g) were randomly divided into three groups. Group (TBE) received tribromoethanol solution (250mg...
