2012). Harmful pathogens are targeted with different antimicrobial agents according to their toxicity in order to sufficiently eliminate them. Such agents include disinfectants, Antiseptic, and Antibiotics. Microorganisms are prevented, killed and eliminated from living tissue and on inanimate objects through application of disinfectants and antiseptics…
1. (4 points) The results below were obtained from a use-dilution test of two disinfectants. Cultures were inoculated into tubes with varying concentrations of disinfectants and incubated for 24 hr at 20°C, then subculture in nutrient media without disinfectants. (+ = growth; - = no growth) Disinfectant 1 Disinfectant 2 Concentration Initial Subculture Initial Subculture Most concentrated 1:10 - + - - 1:90 + + - - 1:900 + + - - 1:90,000 + + - - 1:900,000 + + - + 1:9,000,000 + + - +…
In everyday life, people use disinfectants, substances used to destroy viruses and microbes such as bacteria and fungi1, to clean their bathrooms. If not properly sterilized and cleaned, the bathroom can be a domain for numerous bacteria including ubiquitous Serratia Marcescens, a short, rod shaped, facultative anaerobic, opportunistic pathogen that can cause nosocomial infections such as urinary tract infections, bacteraemia, meningitis, sepsis and cerebral abscesses2. Facultative anaerobic…
natural product; vinegar, is better than man made chemical products; Domestos and Pine O clean. This will be determined by the results of the experiment which product has created the largest zone of inhibition. To determine which of the three disinfectants are the most effective depend the one with the largest inhibition zone. Bacteria are tiny microorganisms that colonise together and are found in every living organism. Bacteria is a type of Prokaryotes and RESEARCH Some Bacteria can be…
the organism. The second type is Antiseptics, these are microbial agents used on the skin and they are harmful to microbes. The third type is Disinfectants and these types of antimicrobial agents are used on inanimate objects like counter tops and they also kill and inactivate microbes. In order to test how well antibiotics, antiseptics, and disinfectants work on two different types of bacteria (S.…
1900s chlorine started to be used as a disinfectant in water. Water had to be chlorinated because of waterborne pathogens which would then go and cause deadly diseases which flourished in our pipes and water ways and infected millions of people. But ever since the disinfection of water the most of these diseases have been eliminated in first world countries but is still a big problem in 3rd world problems. (Calomiris, 1998) Chlorine is the most used disinfectant around the world for water…
Introduction: The world of antiseptics and disinfectants is ever changing. There are many different options out there and people have to decide what is the best option for them. For the experiment we performed in class, we had a variety of different options to use to see what the results would be from these. The range of items used were from and everyday household product of Lysol to Iodine which can be used in the operating room to prep the patient for the type of surgery they are having done.…
Chlorine is added to drinking water, as a disinfectant, to get rid of harmful bacteria, which are usually present in areas from where the water is obtained. The controversy of this issue is that chlorination can work as an advantage or as a disadvantage to those consuming it. Chlorine is currently the most effective water treatment when compared with other alternatives. However, it also reacts with natural organic compounds present in the water to produce harmful chemicals that on a long-term…

was placed on the surface of the agar using the antibiotic disc dispenser. Once the disk was placed on the agar surface, it was not to be moved. The plate was inverted into the incubator at 37 degrees Celsius. Procedure III: Antiseptics and Disinfectants Basic Technique A. Alcohol Flame Sterilization of…
