The essential oil extracted from the dried flower buds of clove, Eugenia caryophyllata L. Merr. & Perry (Myrtaceae), is used as a topical application to relieve pain and to promote healing and also finds use in the fragrance and flavouring industries. The main constituents of the essential oil are phenylpropanoids such as carvacrol, thymol, eugenol and(More)
Vibrio alginolyticus was isolated from the internal organs of diseased gilthead sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax) cultured in two fish farms located on the Tunisian Mediterranean coast, from 2003 to 2005. After phenotypic characterisation, a selection of 34 isolates from gilthead sea bream and sea bass were molecularly typed by(More)
In seawater, enteric bacteria evolve toward a stressed state that is difficult to identify because of major alterations of their phenotype. In this study, we incubated four reference strains of S. enterica serovar Typhimurium in seawater microcosms for 10 months and studied the modifications of their main phenotypic characters. All of the strains lost some(More)
Many essential oils are known to possess an antioxidant activity and antifungal properties and therefore they potentially act as antimycotic agents. Essential oil of clove (Eugenia caryophyllata) was isolated by hydrodistillation. The chemical composition of the essential oil was analysed by gas chromatography and gas chromatography/mass spectroscopy. The(More)
This study characterises the bacteria associated with a marine hatchery in Tunisian coastal marine waters. Presumptive vibrios (TCBS agar) and heterotrophic aerobic microflora (CFU) were studied at different stages within the hatchery: seawater, batches of algal cultures, rotifers andArtemia culture tanks. The bacterial strains were isolated on TCBS Agar(More)
Staphylococcus aureus and Coagulase-negative staphylococci (CoNS) are a major source of infections associated with indwelling medical devices. Many antiseptic agents are used in hygienic handwash to prevent nosocomial infections by Staphylococci. Our aim was to determine the antibiotic susceptibility and resistance to quaternary ammonium compound of 46 S.(More)
The ability of Vibrio alginolyticus strains isolated from a bathing and fishing area (Khenis, Centre of Tunisia) to adhere to both biotic and abiotic surfaces was evaluated in the present work. The biochemical, physiological and enzymatic activities of all strains was also investigated. Three morphotypes of V. alginolyticus were obtained on Congo red agar(More)
We analysed 34 Vibrio alginolyticus strains isolated from gilthead sea bream Sparus aurata L. and sea bass Dicentrarchus labrax L. cultured in fish farms on the Tunisian Mediterranean coast for the presence of several virulence properties such as extracellular products (ECP) production, growth in iron-limiting conditions and survival in fish serum. The(More)
The aim of this study was to evaluate the survival responses of four strains of Vibrio alginolyticus in seawater under starvation conditions. We used microcosms containing sterilised seawater and incubated at ambient temperature (22-25 degrees C). V. alginolyticus maintained its culturability for at least nine months. Long-term-starved cells showed an(More)
Cytochrome P450 (CYP)1A1 gene polymorphism has been shown to be associated with several diseases. In this study, we evaluated the association between the polymorphism in the cytochrome P-450 (CYP)1A1 (CYP1A1) gene and genetic susceptibility to prostate cancer (PCa) in Tunisian men. One hundred and thirty eight PCa patients and the same number of controls(More)
