temperature like endospore. Therefore‚ the amount of bacteria would decrease as the heating persists. Germicides are disinfectants or chemicals used to kill germs which are mainly pathogenic microorganisms present in the environment. (Farlex‚ 2012) Germicides are formulated to break down and destroy pathogenic microorganisms. In this experiment‚ 4 types of germicides are used to control the growth of bacterial populations which are Dettol‚ 5% Savlon‚ 3% H2O2 and Listerin. A paper disc is used to transfer

Cross Infection Definition Cross infection is the physical movement or transfer of harmful bacteria from one person‚ object‚ or place to another‚ or from one part of the body to another (such as touching a staph-infected hand to the eye). When this cross infection occurs in a hospital or long-term care facility it is called a nosocomial infection. Community acquired infections are those contracted anywhere except a hospital or long-term care facility. Description Cross infection accounts for

has many advantages and disadvantages. Advantages and Disadvantages Ozone is more effective than chlorine in destroying viruses and bacteria and after ozone there are no regrowth microorganisms unlike ultraviolet and chlorine disinfection. Also ozonation‚ which is a water treatment process that kills microorganisms‚ increases the dissolved oxygen concentration of the discharged wastewater. The increase in dissolved oxygen can improve the oxygen content of the receiving body of water. Another adcantage

simplicities. Yet a microorganism calls places like these “home”. These microbes are called extremophiles‚ prospering in extreme environments where humans can’t. Barren or poisonous environments that other organisms would perish in tend to be the extremophile’s hot spots (Rothschild‚ 2001). They reach their full potential within these environments. Without these environments‚ lifecycles like reproduction wouldn’t take place at all. Extremophiles are wide spread and well diverse microorganisms. Lactobacillus

A surgical site infection(SSI) is defined when a microorganism settles into and contaminates sterile tissue within 30 days of the surgery. Per the CDC (2017) SSIs are responsible for 31% of healthcare-associated infections or nosocomial infections which is the highest leading cause. This can happen before during or after a patient has surgery. There are many physiological risks that are evaluated before a person has surgery to see if they are at a high risk for a surgical site infection. Some

Help maintain the balance of living organisms and chemicals in our environment. Marine and fresh water microorganisms form the bases of the food chain in oceans‚ lakes‚ and ricers. Soil microbes help break down wastes and incorporate nitrogen gas from the air into organic compounds‚ thereby recycling chemical elements between the soil‚ water‚ life‚ and air

“About 4 billion years ago‚ microbes appeared on earth and about 130 years ago the first microbe was discovered” (Crawford ix). Microorganisms are the simplest and smallest form of living things on earth and they are very powerful. Microbes can be used for ecological purposes‚ some are also pathogenic and others have helped in the medical field to create antibiotics. The author‚ Dorothy H. Crawford is Professor of Medical Microbiology and Assistant Principal for the Public Understanding of Medicine

Its growth has forced scientists to investigate the impact of the increase. It is known that greenhouse gases cause global warming that consequently cause droughts‚ the spread of diseases and changes in the ecosystem among other effects (Reay‚ 2010 p.76). Researchers noted that freshwater microorganism‚ through the process of methanogenesis

(Include a description of the envelope‚ capsid‚ and core The nucleic acid of a virus is protected by a protein coat called the capsid. The structure of the capsid is ultimately determined by the viral nucleic acid and accounts for most of the mass of a virus‚ especially of small ones. Each capsid
