Disinfectant

Worldwide chlorine is still the most used disinfectant; its ability to kill harmful microorganisms is more than enough for some. Although some by-products are formed many people believe the evidence for carcinogenic risks due to chlorination is not strong enough for the process to be completely eliminated…

Medieval Chinese Medicine Medieval Chinese medicine influenced modern day medicine, as well as advancing their own knowledge y inventing and discovering. Firstly, Chinese medicine was a system created 3,000 years ago. Through medieval Chinese medicine fatigue and food/herbal causes, atmospheric forces, acupuncture, t’ai chi, and discoveries for disease prevention were all formed. These elements helped shape the medicine used today and helped medieval Chinese medicine tremendously. Chinese…

dropping pipette. Flame the bottle neck again and replace the cap. Lift the lid of the Petri dishes. Place 2-5 drops of culture in the centre of the dishs. Replace the lid as quickly as possible. Discard the dropping pipette into the beaker of disinfectant. Take the bottle of melted agar. Remove the cap and pass the neck through the Bunsen burner flame 2-3 times. Pour the contents into the Petri dishes carefully. Replace the lid as quickly as possible. Flame the neck again and replace the cap…

They shows high tolerance towards many disinfectants used. Although the microbial cells within are vulnerable, they gain protection from the EPS in the matrix which retards penetration of some disinfectants into the biofilms. Some of the cells within also activate the response pathways to the different antimicrobials. The biofilm may also provide different microenvironments…

Microbial contamination is a constant problem, which often compromise development of all in vitro techniques. Therefor cleanliness and proper care of equipment are vital to the operation of a tissue culture laboratory to avoid the risk of contamination. In this practical, the main objective was to observe the sources of contamination and to learn maintenance techniques which are relevant to avoid the risk of contamination in the laboratory premises. While observing the cultures,…

are disinfectants and antiseptics. Disinfectants kill nearly all microbials on hard surfaces, with the exception of spores and antiseptics are typically used to inactive or destroy organisms on skin or living tissue (Grainger Incorporation, 2016). Although there is no conclusive research about the effectiveness of different microbial agents, due to the features of bacteria constantly changing, there are theories about how they affect the growth of bacteria. Firstly, bleach is a disinfectant…

Bleach was found to be a successful disinfectant against the bacterium S.epidermidis and E.coli, at all concentrations. Bleach is a household chemical substance that acts as a halogen-releasing agent specifically releasing chlorine. As bleach is an oxidizing agent, it facilitates the surge of cellular activity of Hsp33, which are redox-regulated chaperone proteins of the bacterial cell. This chaperone protein prevents the bleach from oxidizing the bacteria, which protects the cell against…

Modes of infectious disease transmission Infectious diseases are contagious contra -indications towards beauty treatments, created by organisms such as bacteria, fungi or viruses. The human body carries many living organisms internally and externally that are treatable, although if left undiagnosed the organisms may cause disease. Bacterial Infections, (Impetigo, Conjunctivitis or Styes), Viral Infections (Herpes Simplex, Shingles or Warts), Infestations (Scabbies, Head lice or Pediculosis)…

A Murky Situation: The Flint Water Crisis Most Americans would readily agree that all people deserve the right to clean water, but the when they realize the large monetary commitment this requires, the water becomes murky, both literally and figuratively. This phenomenon is pronounced in Flint, Michigan. The downturns of the auto industry in the 1980s wrecked havoc in this prominently black city to the extent that today about 40% of its citizens live under the poverty line. In 2014, Flint sought…
