The intensive use of antibiotics in aquaculture has resulted increased resistance among fish pathogens, and this situation led researchers to investigate the antibacterial properties natural resources. present study focused on an essential oil isolated from leaves Eucalyptus camaldulensis as a potential that could be used against Aeromonas caviae. Eighteen compounds were identified oil, represe...

Eleven essential oils (EOs) were evaluated for their antibacterial properties, against Vancomycin-Resistant Enterococci (VRE) and E. coli O157:H7. EOs were introduced into Brain Heart Infusion agar (BHI) (15ml) at a concentration of 0.25 to 2% (vol/vol) to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for each pathogen evaluated. Results showe...

An alarming increase in biofilm forming methicillin-resistant Staphylococcus aureus (MRSA) possesses a serious problem in hospital environment demands a renewed effort to seek agents from natural system that are effective against pathogenic bacteria resistant to current antimicrobials. In the study, the distribution of biofilm forming MRSA and the antibacterial activity of essential oils (Eucal...

HIGHLIGHTS Eucalyptus cinerea essential oil (EO) contains 1,8-cineole as the main component. This EO demonstrated antioxidant and antimicrobial properties. reduced viability of Jurkat Calu-3 cells decreased DNA content. had cell death mechanism related to apoptosis.

Because of its resistance to antibiotics, Staphylococcus aureus causes many of problems in hospital and society. As one of the main reasons of clinical infections it can cause to serious surgical and cutaneous infections and pneumonia. The inhibitory effect of the essential oils include; Eucalyptus largiflorence, E. camaldulensis, E. malliodora and E. polycarpa as a natural and herbal antimicro...

The present study was undertaken to explore the bioherbicidal potential of essential oil(EO)(25 to 250μg/ml) from Eucalyptus tereticornis against one of the major weed of rice (Oryza sativa L.), i.e. Echinochloa crus – galli L. considering percent germination, root length and shoot length development chlorophyll, protein and carbohydrate content and percent cellular respiration). Studies reveal...

Phytotherapy may be an alternative strategy for controlling gastrointestinal parasites. This study evaluated the anthelmintic efficacy of Eucalyptus citriodora essential oil (EcEO). The in vitro effects of EcEO were determined through testing the inhibition of egg hatching and larval development of Haemonchus contortus. EcEO was subjected to acute toxicity testing on mice, orally and intraperit...

The present investigation is design to determine the chemical composition of the essential oil of Eucalyptus camaldulensis grown in Egypt and to study its antioxidant and cytotoxic effects on different cancer and normal cell lines. The analysis of E. camaldulensis oil using GC/MS resulted in the identification of 43 compounds. The current results indicated that the essential oil has weak radica...

Biomass can be envisaged as a potential solution to mitigate the problems that extensive exploitation of fossil sources causes on environment. Transforming biomass into added-value products with better calorific properties is highly desired. Thermochemical liquefaction convert bio-oil. The work herein presented concerns study direct Eucalyptus globulus sawdust. main goal was optimise operating ...
