result of overuse‚ misuse‚ and abuse‚ antibiotics‚ once hailed as the savior of mankind‚ are an increasing threat as bacteria grow ever stronger. (Bunyard) The development of antibiotic-resistant bacteria poses a looming threat to the medical industry and to society. A quick look into modern newspapers or journals would reveal startling reports about antibiotic-resistant bacteria‚ also known as superbugs‚ and how devastating their emergence could potentially be.

differences between bacteria‚ viruses‚ fungi and parasites. Bacteria – bacteria are extremely small singular organisms which are found almost everywhere. Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. Fungi – it is a multi-celled living organism Parasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 1.2 Identify common illnesses and infections caused by bacteria‚ viruses‚ fungi

Microorganisms are capable of causing infection or spoilage. Controlling bacterial growth is important in poultry farm businesses that use equipment to decontaminate processing plant fluids before disposal. During quality control and safety evaluations‚ bacteria growth that needs to be controlled can be found. While controlling bacterial growth‚ clusters of Gram Positive Cocci were found. It was found some ways to control bacterial growth were disinfection‚ sterilization‚ antisepsis‚ sanitization‚ moist

growth of bacteria and fungi. Aim: our aim was to see weather or not garlic‚ mint and grass contained antimicrobial properties and if they did how effective they were we were trying to see weather the bacteria will grow around the different plants. Control Test: As a control test what we did was‚ we dipped a paper disc into the alcohol solution we used to dissolve the plants; the reason we did this was to test to see weather or not the alcohol would affect the end result. If bacteria grew around

Also‚ the ions that prevention generation ion-pair‚ it has a positive effect on antibacterial activity because it allows the polymer to interact freely with the bacteria [31] [50].” 2.3. 3 Spacer Length or Alkyl Chain Length “The length of the spacing or length of the alkyl chain indicates the length of the carbon chain that is the

This is done by protecting the bacteria from multiplying‚ so the level of risk is not too high By cooking food you can destroy the harmful bacteria The basic rules of food hygiene: Before you start to cook or prepare foods you should always make sure that your hands are washed and hair is up and in a cap.

Bio-112 Antibiotic Resistance Experiment Lab Partners: March 10‚ 2010 When we initially started the bacteria antibiotic experiment on February 10‚ 2010 our team selected e-coli and Rifampicin (Rb5) to find out the level of resistance e-coli would build towards this antibiotic. When we first checked our agar dish on February 15‚ 2010 we noticed two circles for the zone of inhibition the small circle was 1.5 cm and the medium circle was 3.00 cm. Two days later when we checked

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

the street. Bacteria have the ability to do this. Through the processes of transformation‚ transduction‚ and conjugation bacteria are able to exchange DNA and as a result increasing genetic variety. “In transformation‚ the recipient bacterium takes up extracellular donor DNA. In transduction‚ donor DNA packaged in a bacteriophage infects the recipient bacterium. In conjugation‚ the donor bacterium transfers DNA to the recipient by mating.” Horizontal gene transfer also allows bacteria to acquire
