Accurate diagnosis of group A streptococcal pharyngitis and appropriate antimicrobial therapy are important, particularly to prevent nonsuppurative sequelae such as rheumatic fever. Most episodes of sore throat, however, are caused by viral agents. Clinical findings cannot reliably differentiate streptococcal from viral pharyngitis and most physicians tend to overestimate the probability of a s...

AIM This study investigated the effectiveness of disinfecting solution when incorporated into alginate powder instead of water against some microorganisms and on compressive strength of alginate. MATERIALS AND METHODS For measuring antimicrobial activity of alginate, 60 alginate specimens were prepared and divided into two groups: One with water incorporated in the mix (control) and the other...

In contact experiments with different experimental conditions, electrochemical Ag+ solutions exhibited better antimicrobial effectiveness against bacteria, a yeast species, and a mold than did analogous silver solutions from inorganic salts. The particular characteristics of electrochemical Ag+, such as the mode of action, effectiveness at low concentrations, and stability, indicate that Ag+ co...

 Background: Essential oils of medicinal plants such as chamomile are very complex natural mixtures which can contain compounds at quite different concentrations and some of their components have antioxidant and antimicrobial activities in foodstuff. Objective: The antioxidant and antimicrobial effects of chamomile essential oil in cake preparation were evaluated during 75 days of storag...

Antimicrobial activity was detected in the 50% ethanolic extract of Ixora coccinea. The effective inhibitory concentration of the extract against both the bacterial test organisms and the fungal test organisms studied was 125 ug mL(-1), beyond which the inhibitory activity declined and the organisms started reviving from the effect of the antimicrobial principle.
