The Association of Official Analytical Chemists (AOAC) test for assessing the tuberculocidal activity of disinfectants has been shown to be variable. A modified AOAC test, which substituted Middlebrook 7H9 broth as the primary subculture medium and used neutralization by dilution, was compared with the standard AOAC method to assess the mycobactericidal activity of three glutaraldehyde-based di...

BACKGROUND Most of the materials (casts, impressions, etc.) that are sent to the dental laboratories show the presence of numerous pathogenic microorganisms. All the spray disinfectants are not equally effective against these microorganisms. AIMS AND OBJECTIVES The aim was to compare the effectiveness of different spray disinfectants on irreversible hydrocolloid impressions and to find out th...

Six different kinds of non-metallic or organic disinfectants were obtained in this research study including “Neutral Electrolyzed Water”, “M22” organic disinfectant solution, Superoxy Food Wash disinfectant, Hydrogen Peroxide, Clorox Germicidal Bleach and Clidox-S. The effectiveness of these disinfectants was studied against various subtypes of avian influenza virus (AIV). The virus-disinfectan...

We evaluated the in vitro efficacy of weak acid hypochlorous solution (WAHS) against murine norovirus (MNV) by plaque assay and compared the efficacy with diluted NaOCl (Purelox) and 70% ethanol. WAHS was as effective as 70% ethanol and diluted Purelox for 0.5-min reactions. For 0.5-min reactions in the presence of mouse feces emulsion, the efficacy of WHAS and 1:600 diluted Purelox was decreas...

The ability of Clostridium difficile to form highly resilient spores which can survive in the environment for prolonged periods causes major contamination problems. Antimicrobial 405 nm light is being developed for environmental decontamination within hospitals, however further information relating to its sporicidal efficacy is required. This study aims to establish the efficacy of 405 nm light...

The West Africa Ebola virus (EBOV) outbreak has highlighted the need for effective disinfectants capable of reducing viral load in a range of sample types, equipment and settings. Although chlorine-based products are widely used, they can also be damaging to equipment or apparatus that needs continuous use such as aircraft use for transportation of infected people. Two aircraft cleaning solutio...

Using disinfectants in agriculture increasingly requires consideration of the indirect effects on the environment and human health. At present, only limited information is available on post-application effects of disinfectants, and such data therefore needs to be gathered in order to assess potential effects. In addition, a basis exists for establishing precautionary guidelines using current in...

Vulvovaginal candidasis is a significant gynaecological infection, which causes extreme discomfort, such as vulvovaginal itching. Using modified agar well-diffusion method, this study therefore, investigates in vitro inhibitory / cleansing potentials of soaps, germicides and disinfectants on vulvovaginal Candida species, especially with regards to vulvovaginal itching. Crusader oil (100%), Meri...
