performance of lactating friesian cows fed a diet supplemented with Coriander oil feed intake nutrient digestibility ruminal fermentation blood chemistry and milk production
Animal Feed Science and Technology, 2017Co-Authors: O H Matloup, A Abd El M Tawab, A A Hassan, Fatma I Hadhoud, M S A Khattab, Mohamed S Khalel, Sobhy M A Sallam, Ahmed E KholifAbstract:Abstract Thirty multiparous lactating Friesian cows (523 ± 8.9 kg BW) were used to study the effect of feeding Coriander oil, a natural feed additive, versus salinomycin; an ionophore. Early lactation Friesian cows were used for 63 days in a completely randomized experimental design with repeated measures. Cows were randomly assigned to three treatments and fed a basal diet of concentrates, berseem clover (Trifolium alexandrinum) and rice straw in a ratio of 40:40:20 DM basis. The treatments were: (1) the basal diet with no additive (Control treatment); (2) the basal diet supplemented with 4 g/cow daily of salinomycin (Salinomycin treatment); and (3) the basal diet supplemented with 14 mL Coriander oil/cow daily (Coriander treatment). Cows in the salinomycin and Coriander groups had greater feed intake (P 0.05) by the salinomycin and Coriander treatments. Greater serum glucose concentration (P = 0.013), without affecting other blood measurements, was noted with Coriander and salinomycin treatments. Similarly, Coriander and salinomycin resulted in greater (P

Cows in the salinomycin and Coriander groups had greater feed intake ( P 0.001) and nutrient digestibility ( P 0.01) than control cows. Ruminal ammonia-N concentration was lowered ( P versus the other two treatments. Concentrations of total and individual short-chain fatty acids were not affected ( P > 0.05) by the salinomycin and Coriander treatments. Greater serum glucose concentration ( P = 0.013), without affecting other blood measurements, was noted with Coriander and salinomycin treatments. Similarly, Coriander and salinomycin resulted in greater ( P 0.05) daily outputs of milk, energy corrected milk, fat, and milk energy, and both salinomycin and Coriander improved milk efficiency ( P 0.05) compared with control. It is concluded that Coriander oil at 14 mL/cow daily can replace ionophore salinomycin in the diet of early lactating Friesian cows. Enhanced feed utilization and lactational performance were observed with Coriander oil supplementation without any negative effect on animal health.

synergistic activity of Coriander oil and conventional antibiotics against acinetobacter baumannii
Phytomedicine, 2012Co-Authors: Andreia Duarte, Filomena Silva, Susana Ferreira, Fernanda C DominguesAbstract:Abstract In this study we investigated the existence of synergistic antibacterial effect between Coriander (Coriandrum sativum L.) essential oil and six different antibacterial drugs (cefoperazone, chloramphenicol, ciprofloxacin, gentamicin, tetracycline and piperacillin). The antibacterial activity of Coriander oil was assessed using microdilution susceptibility testing and synergistic interaction by checkerboard assays. The association of Coriander essential oil with chloramphenicol, ciprofloxacin, gentamicin and tetracycline against Acinetobacter baumannii showed in vitro effectiveness, which is an indicator of a possible synergistic interaction against two reference strains of A. baumannii (LMG 1025 and LMG 1041) (FIC index from 0.047 to 0.375). However, when tested the involvement between Coriander essential oil and piperacillin or cefoperazone, the isobolograms and FIC index showed an additive interaction. The in vitro interaction could improve the antimicrobial effectiveness of ciprofloxacin, gentamicin and tetracycline and may contribute to resensitize A. baumannii to the action of chloramphenicol.

antifungal activity of coriandrum sativum essential oil its mode of action against candida species and potential synergism with amphotericin b
Phytomedicine, 2011Co-Authors: Filomena Silva, Susana Ferreira, Andreia Duarte, Dina I M D De Mendonca, Fernanda C DominguesAbstract:The increasing incidence of drug-resistant pathogens and toxicity of existing antifungal compounds has drawn attention towards the antimicrobial activity of natural products. The aim of the present study was to evaluate the antifungal activity of Coriander essential oil according to classical bacteriological techniques, as well as with flow cytometry. The effect of the essential oil upon germ tube formation, seen as an important virulence factor, and potential synergism with amphotericin B were also studied. Coriander essential oil has a fungicidal activity against the Candida strains tested with MLC values equal to the MIC value and ranging from 0.05 to 0.4% (v/v). Flow cytometric evaluation of BOX, PI and DRAQ5 staining indicates that the fungicidal effect is a result of cytoplasmic membrane damage and subsequent leakage of intracellular components such as DNA. Also, concentrations bellow the MIC value caused a marked reduction in the percentage of germ tube formation for C. albicans strains. A synergetic effect between Coriander oil and amphotericin B was also obtained for C. albicans strains, while for C. tropicalis strain only an additive effect was observed. This study describes the antifungal activity of Coriander essential oil on Candida spp., which could be useful in designing new formulations for candidosis treatment.

Coriander coriandrum sativum l essential oil its antibacterial activity and mode of action evaluated by flow cytometry
Journal of Medical Microbiology, 2011Co-Authors: Filomena Silva, Susana Ferreira, Joao A Queiroz, Fernanda C DominguesAbstract:The aim of this work was to study the antibacterial effect of Coriander (Coriandrum sativum) essential oil against Gram-positive and Gram-negative bacteria. Antibacterial susceptibility was evaluated using classical microbiological techniques concomitantly with the use of flow cytometry for the evaluation of cellular physiology. Our results showed that Coriander oil has an effective antimicrobial activity against all bacteria tested. Also, Coriander oil exhibited bactericidal activity against almost all bacteria tested, with the exception of Bacillus cereus and Enterococcus faecalis. Propidium iodide incorporation and concomitant loss of all other cellular functions such as efflux activity, respiratory activity and membrane potential seem to suggest that the primary mechanism of action of Coriander oil is membrane damage, which leads to cell death. The results obtained herein further encourage the use of Coriander oil in antibacterial formulations due to the fact that Coriander oil effectively kills pathogenic bacteria related to foodborne diseases and hospital infections.

Kajian Kekhususan Inang Stegobium paniceum (Coleoptera: Anobiidae)
Universitas Gadjah Mada, 1998Co-Authors: F. X. Wagiman, V. PoerdriestiAbstract:The study of the host range of Stegobium paniceum (L.) (Coleoptera: Anobiidae) was conducted at the Laboratory of Research center for Biological Control (RCBC), Gadjah Mada University, under room temperature of 26.55±0.72oC–30.66±0.40oC and 57.38±5.53% relative humidity. The materials tested were seventh materials of stored products in their original and flour form. No Choice Method and Free Choice Method were to determine the applied host range and host specificity. New generation of S. paniceum produced from a material was used to indicate that the material was its host. The results showed that the main host of S. paniceum was Coriander, and its alternative hosts were caraway seed, rice, dry ginger, candlenut, and nutmeg, while S. paniceum could not survive on pepper. The material form did not significantly affect the S. paniceum development. Key words: Stegobium paniceum, Anobiidae, coriande

Kajian Aspek Biologi Stegobium Paniceum (Coleoptera: Anobimae) = Study On The Biological Aspects Of Stegobium Paniceum (Coleoptera: Anobiidae)
[Yogyakarta] : Perpustakaan UGM, 1998Co-Authors: V. Poerdriesti, F. X. Wagiman, Koeswari AnandaAbstract:The biological aspects of Stegobium paniceum (L.)(Coleoptera: Anobiidae) was studied by culturing the insect on Coriander seeds at the Laboratory of Research Center for Biological Control (RCBC), Gadjah Mada University, under room temperature of 26.5510.72°C - 30.66±0.40°C and 57.38±5.53% relative humidity. The results showed that egg, larval and pupal stages of S. paniceum were 9.15±1.3735.97±5.53 and 5.80±0.54 days, respectively. Females laid eggs firstly at 5 days old, hence, the life cycle was 55.92 days. The female produced eggs for 4.691-3.42 days, as many as 13.6799.39 eggs. The eggs were laid in the Coriander seedsup to more than 50 eggs per seed, but only 68.54±-29.27% out of them hatched and one to three individuals of them developed into adult. Larvae and pupae lived in the Coriander seeds or in the Coriander powder. The adults did not eat and could survive for. 27.90±18.71 days, but could cause damage by making exit holes on the Coriander seeds. The pest might cause Coriander damage up to 80%.
