the purpose of this research was to study the neutralization efficacy of a universal neutralizer proposed by the ctpa on a range of antimicrobial agents and its potential toxicity for microorganisms that are used for antimicrobial preservation testing. several types of antimicrobial agents including a mixture of methylisothiazolinone and its 5-chloro derivative, dimethylol dimethyl hydantoin, q...

introduction: an ideal intracanal medicament should be able to eliminate any remaining intracanal microorganism. the aim of this study was to compare the antimicrobial effects of bioglass 45s5 with calcium hydroxide on enterococcus ( e ) faecalis in-vitro . materials & methods: direct exposure test (det) was used to evaluate the antimicrobial effect of bioglass 45s5, calcium hydroxide and norma...

The antimicrobial activity of a wound dressing is a key factor for preventing and treating wound infection. The current study evaluated the physiochemical properties and antimicrobial activities of semi-IPNs (interpenetrating polymer networks) based on chitosan/polyvinyl alcohol (PVA) films and nanofibers as candidates for wound dressings and investigated the effects of morphologies (nanofibrou...

To test for antimicrobial activity, crude extractions of the fruit of Barringtonia edulis were performed using traditional Hawaiian implements of a stone grinder (poi pounder) and a wooden board. The Kirby-Bauer method was used to test the antimicrobial properties of these extractions against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, and Candida albican...

   Disk diffusion test is the usual applicable method for assessing the antimicrobial susceptibility pattern in most institutions and hospitals. The aim of this study was to determine the reliability of resistant-reported results of disk diffusion test for 6 routinely used antibiotics against Gram-positive microorganisms of nosocomial origin, using E-test method.    Over a 1-year period, clinic...

This study analyzes the National Residue Program (NRP) of the Food Safety and Inspection Service (FSIS), United States Department of Agriculture (USDA), data for the years 1983-1998 to determine the effectiveness of all three microbiological screen tests that were developed and used by the FSIS to control antimicrobial residues in food animals. The Swab Test On Premises (STOP) was the first scr...

Effect of different solvents; dimethyl-sulfoxide (DMSO), dimethyl formamide (DMF), methanol, tween 80 and acetone on morphology, cytology and reproduction of Aspergillus flavus, A. parasiticus, A. fumigatus and A. niger was assayed for standardization of a suitable organic solvent for test/antimicrobial compound in antimicrobial assays. Comparison of antimicrobial sensitivity methods was also m...

PURPOSE A significant barrier to efficient antibiotic management of infection is that the standard diagnostic methodologies do not provide results at the point of care. The delays between sample collection and bacterial culture and antibiotic susceptibility reporting have led to empirical use of antibiotics, contributing to the emergence of drug resistant pathogens. As a key step toward the dev...

INTRODUCTION The antimicrobial efficacy of root canal irrigant plays an important role in increasing the success of root canal treatment (RCT). The aim of the present experimental study was to compare the antimicrobial activity of Triphala (a plant-derived solution) with 0.5, 1, 2.5 and 5% concentrations of sodium hypochlorite (NaOCl), against Enterococcus faecalis (E. faecalis). METHODS AND ...
