zhumeria majdae is a rare an endemic medicinal plantspecies grown wild in iran. the hydro distilled essential aerial part oil of z. majdae analysed by gc–ms. thirty-one compounds representing 95.36% of the aerial part oil, respectively, were identified, of which linalool (48.14%), camphor (20.71%), limonene (4.83%), trans-linalool oxide (2.69%), 3-octanone (2.34%), terpinene-4-ol (2.30%), camph...

Background and Aim: This study aimed to compare the effects of acetone and ethanolic extracts of Plantago major (P. major) on S. mutans.   Materials and Methods: In this in vitro study, the antibacterial effects of eight different concentrations of the acetone and ethanolic extracts of P. major seed were examined on S. mutans, and the minimum inhibitory concentration (MIC) and minimum bacte...

the infections risk related to pathogenic germs increases at the present time considering the increased resistance which certain microbes acquire, whose usual antibiotics are ineffective to treat the infectious disease. the aim of this study was to determine antimicrobial effect of the aqueous and ethanolic extracts of lavandula stoechas l. and rosmarinus officinalis l. on listeria monocytogene...

Abstract In this study, minimum inhibition concentration (MIC) and bactericidal (MBC) were estimated for three types of zinc oxide (ZnO) nanoparticles on a Gram-positive bacterial species: Streptococcus mutans . The structural properties these nanoparticles, designated as ZnO-A, ZnO-K, ZnO-Ax, characterized using the techniques field-emission scanning electron microscopy, X-ray diffraction, pho...

Emergence of resistance among pathogenic bacteria against available antibiotics is posing a great challenge to the current world. Thus, there is a great need to discover novel antibiotics. Traditional plants have been proved to be novel source in the search of antimicrobial compounds. The current study pertained to the susceptibilities of some clinically significant bacterial species to various...

The molecule BV-1 is designed to target the bacterial membrane and produce reactive oxygen species at this location, leading E. coli photo-inhibition a relatively low minimum inhibition concentration.

conclusions the kin gingival chlorhexidine mouthwash has a greater effect than behsa and boht mouthwashes on oral microorganisms and is recommended to be used for plaque chemical inhibition. results the mics for kin gingival, behsa and boht mouthwashes were 0.14, 0.48 and 1000 micrograms/ml using the tube method for s. mutans, respectively. the mbcs for the mentioned mouthwashes were 0.23, 1.9 ...
