ABSRACT - [ Total Page(s): 1 ]Ethanol, Bleach and Phenolics are three kinds of disinfectants which have been widely used in common laboratories. In this study, a compared experiment on these three disinfectants efficiency was conducted against Staphylococcus aureus and Pseudomonas aeruginosa using agar hole diffusion method. Different concentrations of bleach (1%, 2%, 3%, 4% and 5%) were used on both organisms. Also (50%, 60%, 70%, 85% and 95%) of ethanol as well as (5%, 10%, 20%, 25%, and 30%) Phenolics were used. Diffrences in concentrations tested was because, the original concentrations of the disinfectants diffe

CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONE1.0 INTRODUCTION Microorganisms are minute living things that individually are too small to be seen with the unaided eyes (Tortora et al, 2007). Though only a minority of microorganisms are pathogenic (disease producing), practical knowledge of microbes is necessary for medicine and related health sciences. For example hospital workers must be able to protect patients from common microbes that are normally harmless but pose a threat to the sick and injured. Thousands of people died in devastating epidemics; the cause of which w ... Continue Reading
