background and objectives: dental caries is still remained as a major health problem. this problem has created a new interest to search for new antimicrobial agents from various sources including medicinal plants. since limited data is available so far regarding the antibacterial effect of coriandrum sativum seed and dentol drop against streptococcus mutans, this study aims to assess this activ...

The importance and use of herbal remedies (turmeric, tulsi, amla and aloe vera etc.) has been reviewed systematically. Turmeric (curcumin), acts as an antioxidant, antimutagenic, antiinflamatory and antimicrobial agent and protect liver against a variety of toxicants. Tulsi (eugenol) have anticancer properties, reduced blood glucose levels, total cholesterol levels and promotes immune system fu...

Multispecies bacterial communities such as the microbiota of the gastrointestinal tract can be remarkably stable and resilient even though they consist of cells and species that compete for resources and also produce a large number of antimicrobial agents. Computational modeling suggests that horizontal transfer of resistance genes may greatly contribute to the formation of stable and diverse c...

Tel.: +86-451-8219-1693 An antimicrobial superabsorbent was prepared by grafting polyacrylic acid on tara gum and adding chitosan quaternary ammonium salt (2-NHydroxypropyl-3-trimethylammonium chloride chitosan, HTCC). The effect of the amount of HTCC on swelling ratio of the product was investigated. The product was characterized by Fourier transform infrared (FTIR) spectroscopy, scanning elec...

The antimicrobial activity of silver nanoparticles with the clinically important microbes is a major area of research in the field of nanobiotechnology. Syzgium cumini (L.) is used as medicinal plant for anti-diabetic property. The leaves and bark are used for controlling blood pressure and gingivitis. In this present study, we have synthesized silver nanoparticles using Syzygium cumini leaf ex...

The antimicrobial effect of the polyamide 6/66-chitosan blend obtained by extrusion and chitosan-coated plastic films was compared with pure chitosan films and chitosan solution against Escherichia coli, Listeria monocytogenes and Bacillus cereus. The films from polyamide 6/66-chitosan blend had no antibacterial activity, and the chitosan plastic film coating (bilayer system) showed only contac...

Copper and silver are antimicrobial metals, on whose surface bacteria do not grow. As our paper demonstrates, this commonly reported antimicrobial property does not apply to electrochemically active, electrode respiring bacteria. These bacteria readily colonize the surface of these metals, forming a highly active biofilm. Average anodic current densities of 1.1 mA cm 2 (silver) and 1.5 mA cm 2 ...

Chlorhexidine is a broad spectrum antimicrobial agent, which has been into used in the dental practice as major anti plaque agent. not only shows property of substantivity, but due to its property, it various oral diseases. Different uses chlorhexidine are, prime most antiplaque can be root canal irrigant during process treatment, prevention caries results suppression streptococcus mutans cavit...

The protegrin family of antimicrobial peptides is among the shortest in sequence length while remaining very active against a variety of microorganisms. The major goal of this study is to characterize easily calculated molecular properties, which quantitatively show high correlation with antibacterial activity. The peptides studied have high sequence similarity but vary in activity over more th...

POSTER PRESENTATIONs Anatum (16.1 %, 9 farms) followed by Rissen (14.5 %, 7 farms), Typhimurium (11.3 %, 7 farms), Derby (9.7 %, 3 farms), Tilburg (8.1 %, 2 farms), Goldcoast (8.1 %, 1 farm), Typhimurium variant 4,5,12:i:(6.5 %, 4 farms). Serotypes Bovismorbificans, Bredeney, Diarizonae, Grumpensis, Infantis, Kapemba, Kedougou, Ohio, Seftenberg and Virchow were also isolated although less than ...
