The aim of this study was to investigate in vitro the antimicrobial effect and diffusion against E. faecalis of new intracanal medications on the external root surface. The medications tested were a placebo gel (PC); the new formulations with either 3% nitrofurantoin (NIT) or 3% doxycycline hydrochloride (DX) and 2% chlorhexidine (CHX) gel as positive control. The new formulations were tested u...

Propolis is a natural resinous substance collected by bees from tree exudates and secretions. Its antimicrobial activity has been investigated and inhibitory action on Staphylococcus aureus growth was evaluated. The in vitro synergism between ethanolic extract of propolis (EEP) and antimicrobial drugs by two susceptibility tests (Kirby and Bauer and E-Test) on 25 S. aureus strains was evaluated...

The in vitro antimicrobial effect of seaweed extracts belonging to Ascophyllumnodosum and Laminariadigitata were tested against some pathogens (Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, Pseudomonas aeruginosa and Candidaalbicans). In this study, paper disc diffusion assay, absorbance measurements and growth studies were used to elucidate the effects. The organic solvent e...

This study examined the antimicrobial/antifungal ability of a tissue conditioner containing a photocatalyst for Escherichia coli, Streptococcus mutans, Staphylococcus aureus and Candida albicans. The photocatalyst was mixed with tissue conditioners powders at concentrations of 0, 10, 15, and 20 wt%. Tissue conditioners powders containing a photocatalyst were mixed with liquid to make test speci...

BACKGROUND To try established antimicrobial susceptibility patterns and frequency of both nosocomial and community-acquired bloodstream infections and and to try identified the prognostic factors that can be modified. MATERIAL AND METHODS A prospective study of 310 bloodstream infections with clinical significance detected in a non teaching hospital over period from October 2000-2001. A blood...

Most antimicrobial peptides (AMPs) are cationic molecules with a high content of basic amino acids. They often undergo C-terminal amidation that may be related to their antimicrobial activity. Here we describe a mass spectromety (MS)-based approach for identifying novel AMPs. MS is used to profile peptides secreted by endocrine cells. Peptide sequences characteristic of AMPs are selected to tes...

The present study describes the phytochemical profile and antimicrobial activity of Matricaria chamomilla essential oil. The sample of essential oil was obtained from the aerial parts of the plant by hydrodistillation and analyzed by GC–MS. A total 55 compounds were identified mainly including α-Pinene (22.11%), Camphene (10.8%), Sabinene (4%), Limonene(5.64%),1,8-Cineole(6.45%), Camphor (4%) a...

The aim of this study was to examine the antimicrobial susceptibility of 97 Haemophilus parasuis cultured from Australian pigs. As there is no existing standard antimicrobial susceptibility technique available for H. parasuis, methods utilising the supplemented media, BA/SN for disc diffusion and test medium broth (TMB) for a microdilution technique, were initially evaluated with the reference ...

Coastal seawater samples were collected from Rameswaram, Ramanathapuram District. Twenty five bacteria were isolated and identified according to morphology, biochemical tests and selective growth media. The active marine bacteria isolates were assigned to the genera Alteromonas, Pseudomonas, Bacillus and Pseudoalteromonas sp. The TLC autobiographic overlay assay implied that the antimicrobial m...

Ethanolic extracts of 45 Indian medicinal plants traditionally used in medicine were studied for their antimicrobial activity against certain drug-resistant bacteria and a yeast Candida albicans of clinical origin. Of these, 40 plant extracts showed varied levels of antimicrobial activity against one or more test bacteria. Anticandidal activity was detected in 24 plant extracts. Overall, broad-...
