Aims:
The objective of this study was to evaluate virucidal efficacy of the commercially available povidone-iodine formulations Betaisodona solution and Betaseptic Mundipharma (Mundipharma).
Methods And Results:
The quantitative suspension test for virucidal testing of biocides according to the German guideline was used as method. The use of Betaisodona solution resulted in virucidal efficacy, corresponding to >or=10(4)-fold reduction in viral titre, against vaccinia virus, bovine viral diarrhoea virus and polyomavirus SV40 within 0.5 min and adenovirus type 5 within 3-5 min without and with organic load. For inactivation of the most resistant poliovirus type 1, a time interval of >or=60 min was needed. By contrast, Betaseptic Mundipharma inactivated significantly all model viruses for virucidal testing including poliovirus type 1 within 5 min independently from the addition of proteins.
Conclusions:
Betaisodona solution shows a good efficacy against enveloped model viruses as well as against some nonenveloped human viruses, e.g. adenovirus and polyomavirus. Betaseptic Mundipharma has an excellent virucidal efficacy including the inactivation of the most resistent poliovirus type 1.
Significance And Impact Of The Study:
The findings of this study make Betaseptic Mundipharma suitable for virucidal disinfection of the skin within short time intervals.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

01:29Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
