Garlic Extract : Interaction with mechanisms of bacterial resistance

Garlic (Allium sativum) is a medicinal plant which has a diverse biological activities including antioxidant activity, antimicrobial activity, anticancer activity and others… In this article we are focusing on its antimicrobial effect which had been tested individually and in combination with two resisted antibiotics (Ampicillin, Ciprofloxacin) on 3 gram negative bacteria (Proteus mirabilis, klebsiella pneumoniae and Enterobacter aerogenes) to estimate the effect of garlic extract on the activity of the resisted drugs and bacterial resistance mechanism.

Extracting Methods of Essential laurel oil and Fixed oil, Their effects on bacteria

Laurus nobilis is an evergreen plant belonging to the Lauraceae family, native to Southern Europe and the Mediterranean area. This is the report on the composition and bioactivity of laurel essential oil (EO) from leaves and extraction essential oil by two solvents (water and ethanol 69%) using by two devices (Clevenger and evaporator) then we apply the effect of oil and extract on the bacteria. there are some differences between the extraction by water and ethanol . The antibacterial properties of laurel EOs were examined according to the agar well diffusion method The leaf EO showed antibacterial activities against almost all strains of the microorganisms tested, whereas the twig EO was only able to inhibit Staphylococcus aurous and Escherichia coli were the bacterial strains that showed the highest resistance to the laurel EO. The results can benefit the EO industry and bio pesticide development.

Bioactive Materials in Dentistry : Remineralization and Biomineralization

Addresses the use of different bioactive materials in dentistry, considering the performance of these biomaterials in the hard tissues of the tooth, and the response of the dental pulp, as well as the influence of the composition of these materials and of the individual’s systemic alterations in bioactivity and in antimicrobial activity. The several in vivo and in vitro tests to evaluate the bioactivity of a biomaterial will also be addressed.
