The antimicrobial and cytotoxic effects of sodium hypochlorite (NaOCl) and sodium dichloroisocyanurate (NaDCC) were evaluated and compared in vitro. The minimal inhibitory concentration and minimal bactericidal concentration of NaOCl and NaDCC were tested for Streptococcus sobrinus, Streptococcus salivarius, Enterococcus faecalis, and Streptococcus mutans. The cytotoxic effect was assessed by u...

Serious concerns have been expressed about potential health risks of Nano silver containing consumer products (AgNPs) therefore regulatory health risk assessment on such nanoparticles has become mandatory for the safe use of AgNPsinbiomedicalproducts with special concerns to the mutagenic potentials. In this study, we examined the inhibitory and mutagenicity effects of AgNPs in three different ...

The minimal bactericidal concentrations of N-formimidoyl thienamycin (N-f-thienamycin) against 21 strains of enterococci isolated from patients with infective endocarditis were determined by macro- and microdilution methods. By a macrodilution technique with the minimal bactericidal concentration defined as greater than or equal to 99.9% killing of an initial inoculum, all 21 strains of enteroc...

Different aspects are reviewed of the management of emulsified petroleum products in mechanical engineering industries with reference to the waste problem. Poor quality of make-up water, poor hygienic conditions, inadequate design of feed systems and failure to use a suitable bactericide influence the volume that has to be discarded and then subjected to waste treatment. The inadequacy of the f...

Although nowadays there are methods for determining the Minimal Bactericidal Concentration and Minimal Fungicidal Concentration, it is indispensable that the establishment of innovative methodologies could be more practical and cheaper. The new methodology Flash microbiocide is an assay in which one aliquot from 96 well plate of Minimal Inhibitory Concentration test is transferred to another pl...
