The aim of this study was to evaluate the chemical composition of EOs extracted from Origanum majorana (OM-EO), Mentha suaveolens (MS-EO), Rosmarinus officinalis (RO-EO), Salvia officinalis (SO-EO) and Mentha pulegium (MP-EO). Their antioxidant properties and antibacterial activity against Listeria monocytogenes and different serotypes of Salmonella enterica subsp.

Prevalence, characterization and antimicrobial resistance of isolated from beef meat in Meknes city, Morocco.

Introduction: enes is one of the most pathogenic bacteria related to the consumption of contaminated food. This study aims to determine the prevalence of in raw beef meat in Meknes city of Morocco, to evaluate its pathogenicity and resistance to antimicrobials.

Methods: During four seasons, a total of 140 samples were collected from supermarkets, butcheries and Souk (weekly traditional market).

Chemical characterization and adsorption of oil mill wastewater on Moroccan clay in order to be used in the agricultural field.

Oil mill wastewater (OMW) is the main liquid discharge from oil mills, it is considered as a dangerous pollutant due to its toxic chemical compounds which are unloaded directly in the environment without any treatment. The aims of this study were to evaluate the effectiveness of OMW adsorption on clay as a good method for the elimination of toxic chemical compounds and to study the application of treated OMW as an irrigation source in agricultural field. For this, Clay was collected from the city of Agourai (Meknes region, Morocco) and characterized by X-ray diffraction, X-ray fluorescence spectrometry, BET and FTIR analysis.

Antimicrobial Resistance, Virulence Genes, and Genetic Diversity of Isolated from Sausages.

is a major cause of morbidity and mortality in humans worldwide, and the infection with multidrug-resistant strains can cause severe diseases. This study was designed to evaluate the antimicrobial resistance, to detect the virulence genes, and to study the genetic diversity of isolated strains using 16S rRNA sequences. For this, 34 strains isolated from sausages were identified using biochemical and serological methods.

Antibiotic Susceptibility profile of isolated from sausages in Meknes, Morocco.

Background And Aims: is one of the most common causes of foodborne disease worldwide, due to the consumption of food contaminated by their toxins. This study aimed to determine the prevalence and the antimicrobial resistance of isolated from sausages in Meknes city of Morocco.

Materials And Methods: A total of 156 samples (Beef sausages, Turkey sausages, and Artisanal sausages "Merguez") were collected from different shopping sites (butchery, supermarket, street vendors, and weekly market "Souk") and used for the isolation of .

Antimicrobial resistance and genetic diversity of Salmonella Infantis isolated from foods and human samples in Morocco.

Objectives: Genotyping of Salmonella strains is an important molecular tool to discriminate isolates and to improve epidemiological studies when an outbreak occurs. Among the DNA-based genotyping methods, pulsed-field gel electrophoresis (PFGE) is currently used to subtype Salmonella isolates. In this study, the feasibility of genotyping Salmonella enterica serotype Infantis strains using XbaI restriction enzyme was evaluated.

Antimicrobial activity of ZnO-TiO nanomaterials synthesized from three different precursors of ZnO: influence of ZnO/TiO weight ratio.

In this study, ZnO-TiO nanoparticles were synthesized from three different precursors for ZnO (zinc acetate di-hydrate, zinc nitrate hexahydrate and zinc sulfate heptahydrate) and titanium (IV) isopropoxide for TiO. The prepared nanomaterials were calcined at 500 °C for 3 h and characterized by various physicochemical techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and transmission electron microscopy, combined with energy dispersive X-ray spectroscopy (TEM-EDS). The obtained results showed that the crystalline structure, size and morphology of the ZnO-TiO nanoparticles are strongly influenced by the nature of the precursor of ZnO, as well as the ZnO/TiO weight ratio.
