Teucrium polium L. (Labiatae) has long been recognized in folk medicine in the treatment of many pathophysiological implications, such as gastrointestinal disorders, inflammations, diabetes and rheumatism. In this study antimicrobial activity of two crude extracts obtained from Teucrium polium L. was tested against bacterial species. Minimum Inhibitory Concentration (MIC) and Minimum Bactericid...

This study assessed biofilm formation on polystyrene by Staphylococcus aureus, Listeria monocytogenes, L. welshimeri and Escherichia coli, isolated from a slaughtering plant, grown on tryptic soy broth (TSB) using different glucose concentrations. The tested bacteria produced biofilm in at least one of the concentrations used, and some of them were strong biofilm producers.

results the amount of hgbr2 (0.1% wt/vol) and cdso4 (0.2% wt/vol) were considered as lethal doses for l. monocytogenes ptcc 1297 (serotype 4a). different concentrations of pbo could not kill bacteria yet decreased their growth. the bacteria showed different morphologic and biochemical characteristics under each stressor. objectives the aim of this work was evaluate the growth, surface structure...

INTRODUCTION The aim of this study is the evaluation of the effect of Antimicrobial Photodynamic Therapy with Radachlorin on Staphylococcus aureus and Escherichia coli. New windows are open in the antimicrobial field so-call Photodynamic therapy that incorporates a nonpoisonous photosensitizer (PS) with innocuous special wavelength photons to excite the PS. METHODS Two strains of bacteria use...

Background: Controlling and reducing the food-borne illnesses remain one of the most challenging problems encountered by food authorities worldwide. This study was conducted to assess the microbiological quality of chicken breast, chicken liver, local and imported offal, and ground beef meat products sold in the Lebanese retail market. Methods: Thirty-five chicken breast and liver samples prod...

Materials and Methods Paneer is a tempting, nutritious and delicious indigenous dairy product obtained by acid and heat coagulation of milk. In India, where most people are vegetarian in dietary habits, milk products constitute major source of protein and other essential nutrients. Growing tensed environment and diets rich in fat combined with lack of exercise and physical work are leading to c...

The aim of this study was to evaluate antibacterial activity of Pistachia khinjuk fruit oil and extra virgin olive oil. The Pistacia khinjuk fruit oil was extracted using n-hexane by cold maceration and Soxhlet method. Antibacterial activity was evaluated using disk diffusion and micro broth dilution methods on food pathogenic bacteria (Staphylococcus aureus, Escherichia coli and Listeria monoc...

Staphylococcus aureus requires iron for growth and utilizes heme as a source of iron during infection. Staphylococcal surface proteins capture hemoglobin, release heme from hemoglobin and transport this compound across the cell wall envelope and plasma membrane into the bacterial cytoplasm. Here we show that Staphylococcus aureus isdG and isdI encode cytoplasmic proteins with heme binding prope...

Background: In many developing countries, the risk of contracting a food-borne disease is high after consuming contaminated ready-to-eat Street-Vended Foods (SVFs). The main objective of this research was to assess the microbiological quality of SVF groups sold in the Johannesburg Metropolis, South Africa. Methods: A stratified random sampling procedure was used for collecting the ready-to-eat...
