The chemical composition of hydro distilled essential oil from Origanum acutidens (Hand. and Mazz.) Ietswaart was collected from Tunceli (Turkey) were analyzed by GC and GC-MS. Essential oil and methanol extract of Origanum acutidens were tested against Yersinia ruckeri (ATCC 29473), Aeromonas hydrophila (ATCC 607920), Lactococcus garviae (ATCC 43921) Staphylococcus aureus (ATCC 29213) fish pathogenic bacterial strains. The analysis of the essential oil of Origanum acutidens showed the presence of 6 components accounting for 93.8 % of the total amount. Calvacrol (61.8 %), p-cymene (15.5 %) and thymol (12.7 %) that possessed antimicrobial activity were found as the major component. The final concentrations of the methanol extract and the essential oil were determined by using disk diffusion assay. Mean inhibition zones of bacterial strains for Origanum acutidens essential oil varied from 28.0 +/- 1.2 and 36.7 +/- 0.7 mm. The inhibition zones of methanol extract (10 mu L and 20 mu L) of Origanum acutidens against bacterial strains were in the range 8.7 +/- 0.7 - 11.0 +/- 0.6 mm and 12.7 +/- 0.67 - 22.7 +/- 1.3 mm, respectively. Our results suggest that both the methanol extract and the essential oil of Origanum acutidens may be valuable as potential antibacterial agents against the major fish pathogens.

The effect of Tween 20 on antimicrobial effects of acidic (lactic acid), neutral (cetyl pyridinium chloride) and alkaline (trisodium phosphate) decontaminants to reduce the numbers of Salmonella inoculated to broiler carcasses were studied. In addition, survival of Salmonella in waste decontamination fluids was investigated. For this purpose, an average of 7 +/- 1 log(10) cfu/ml Salmonella Enteritidis and Salmonella Typhimurium cocktail was surface-inoculated on to a total of 110 broiler carcasses. Contaminated carcasses were immersed in to tap water (control), lactic acid (LA) (1-2%), cetyl pyridinium chloride (CPC) (0.5-1%), or trisodium phosphate (TSP) (8%) and the combinations of these treatments with Tween 20 (TW20) (0.5%) for 15 min. Results indicated that. Salmonella numbers significantly decreased (P < 0.05) in all groups, except control and 1% LA. No significant difference was found between treatments with and without TW20. In waste decontamination fluids, 6.68 and 3.41 log(10) cfu/ml of Salmonella were recovered from control and CPC groups, respectively, while no viable Salmonella cell was detected in LA and TSP groups by direct plating. It was concluded that regardless of TW20, the antimicrobials tested were effective to reduce Salmonella in poultry carcasses. However, the pathogen may survive in neutral waste decontamination fluid such as CPC and can pose a risk for consumer health by contaminating the plant environment. (c) 2012 Elsevier Ltd.

The aim of study was to compare the effects of supplementation of food with herbal oils (Thymus vulgaris and Foeniculum vulgare) on biochemical properties and electrolytes of rainbow trout infected with Yersinia ruckeri. In total, 120 healthy fish (mean weight 84 +/- 1.02 g) were equally divided into four experimental groups. The experimental study was carried out for one week. The first group was control without supplementation and infection, the second group was infected and without oil supplementation, the third group was supplemented with oils (10 ml.100 g(-1) rates) for one week and infected with Y ruckeri and the last group was oil supplemented without infection. Results indicated that fish fed with dietary supplements showed enhanced bactericidal activity, total protein, albumin, cholesterol, triglyceride and bilirubin compared to the control (P < 0.05). As the value of herbal oils was increased in diets, the plasma glucose level decreased. The levels of K, Na, Ca, and Mg increased whereas Cl values decreased, compared to the control. It can be concluded that diet supplementation with herb oils used in this study can increase disease resistance by increasing levels of some biochemical parameters and electrolytes in rainbow trout to Y ruckeri infection.
