Aims: To determine antibacterial activity of essential oils against bacterial uropathogens.
Study Design: A cross sectional and experimental study.
Place And Duration Of Study: Six selected hospitals in Bushenyi District, Uganda between June 2012 and July 2013.
Methodology: Clean catch midstream urine samples were collected and inoculated on Cystine Lysine Electrolyte Deficient (CLED) agar. The plates were incubated at 37°C for 24hrs to 48hrs. The essential oils were extracted by hydrodistillation of leaves for 4hrs using a Clevenger apparatus. The oil was collected and dried over anhydrous sodium sulphate (NaSO) and kept at 4°C till further use. The antimicrobial activity of essential oils against isolates was determined by agar well method. The MIC of essential oil extract was carried out by microbroth dilution method.
Results: Of the three hundred (300) midstream urine samples collected, 67(22.33%) had significant bacterial growth. is the most common isolate (61.19%, n = 41). The essential oil from showed activity against isolates of , and with mean zone of inhibition (ZI) ranging from 10-22 mm. The essential oils had no inhibitory activity on The minimum inhibitory concentration (MIC) for essential oils ranged from 0.78 to 22 μg/ml. This study showed that essential oils had MIC value of 0.78 μg/ml against and MIC values ranging from 3 to 22 μg/ml against the other tested isolates.
Conclusion: The most common uropathogen was (61.19% n = 41). essential oils exhibited antibacterial activity against majority of the uropathogens, except mean ZI of 10-22 mm and MIC of 0.78 - 22 μg/ml.

Background: Scabies is a debilitating and neglected infectious disease with limited effective treatment options and affecting millions of people worldwide, mainly in poor and overcrowded settings. Essential oils from Australasian Myrtaceae are known to have parasiticidal properties, often attributed to the presence of β-triketones, which are known inhibitors of the tyrosine catabolism pathway through inhibition of hydroxyphenylpyruvate dioxygenase (HPPD).
Purpose: In this study, essential oils from mānuka (Leptospermum scoparium) were evaluated in vitro for miticidal and ovicidal activities and their active β-triketone constituents (flavesone, leptospermone, and isoleptospermone) were identified.
Fingerprinting the emissions of volatile organic compounds emitted from the cooking of oils, herbs, and spices.

Emission rates for volatile organic compounds (VOCs) have been quantified from frying, spice and herb cooking, and cooking a chicken curry, using real-time selected-ion flow-tube mass spectrometry (SIFT-MS) for controlled, laboratory-based experiments in a semi-realistic kitchen. Emissions from 7 different cooking oils were investigated during the frying of wheat flatbread (puri). These emissions were dominated by ethanol, octane, nonane and a variety of aldehydes, including acetaldehyde, heptenal and hexanal, and the average concentration of acetaldehyde (0.

This study aimed to evaluate the antimicrobial effectiveness of cumin seed essential oil (CEO) after encapsulation in chickpea protein-maltodextrin matrix by spray drying and to provide insight into potential use as a natural ingredient in meat-based products. The surface morphology results of encapsulated CEO showed the dispersion in the wall material matrix, and the observed specific common peaks in the FT-IR spectra of encapsulated and non-encapsulated CEO proved the successful encapsulation. The antibacterial activity of non-encapsulated CEO against BC1402, ATCC 27853, Typhimurium ATCC 0402, ATCC 25923 were first evaluated by disc diffusion assay.

The current study had aimed to assess the long-term dietary supplementation with Melaleucae aetheroleum, tea tree essential oil (TTO). The impact on growth performance, biochemical indices, immune function, oxidant/antioxidant activity, gene expression, histopathology, and resistance against Aeromonas sobria in Nile tilapia (Oreochromis niloticus) was investigated. Four groups (with five replicates; G1 (control group, G2, G3, and G4) of Nile tilapia received diets enriched with TTO (doses of 0.
