Problems with Developing New Antibiotics Since Alexander Fleming discovered penicillin in 1928‚ which is the first antibiotics. The use antibiotics skyrocket‚ a microorganism infection from a small cut that could have killed a person now could be solved in a matter of days. However‚ after this huge medical advancement which plummeted the percentage of death from any type of bacterial infection within the years of 1944 to 1972 the human life expectancy jumped by eight years. That huge difference

possible pathological dangers they hold. Therefore‚ it is vital develop methods by which these bacteria are effectively and efficiently destroyed. The core purpose of a sterilizing agent is that it possesses the ability to be biocidal. A biocide is a microorganism or a chemical substance that has the capability of killing living organisms (Prescott et al.‚ 2005). There are many methods by which sterility of liquids and solids can be achieved‚ methods such as; heat‚ filtration‚ radiation or chemicals (Prescott

Aseptic technique includes hand washing‚ the use of sterile gloves‚ mask‚ and gowns‚ sterilization of surgical instruments and other equipment‚ and the use of disinfectants‚ including antiseptics. The definition of asepsis is: 1) freedom from infection 2) prevention of contact with microorganisms. The definition of aseptic is free from infection or septic material;

This lab was conducted in order to understand and apply the scientific method. The experiment tested the effectiveness of reducing microorganism (bacteria) with the use of various hand soaps. b. Hypothesis: If the Harris Teeter Foaming Hand Soap is more effective in reducing bacterial growth than the Soft Soap hand soap‚ then there will be less bacterial/microorganism growth present on the agar plate for the Harris Teeter Foaming hand soap.

Common Causes of Infection Transmission What is Infection? Microbes can lead to an infection only if they have capacity to multiple. Our bodies get infections from pathogenic microorganisms that cannot observe by naked eye such as • Bacteria. These one-cell organisms are accountable for diseases‚ such as urinary tract infections. • Viruses. Is an acellular agent smaller than bacteria consisting mainly of genetic material‚ that can be active in a close environments ranging from the common cold

The microorganisms generally considered suitable for biological warfare include viruses‚ bacteria‚ protozoa‚ and fungi. Toxins (poisonous chemicals) produced by microorganisms also are considered biological weapons. These agents are capable of causing sickness or death in humans or animals‚ destroying crops‚ or contaminating water supplies

Introduction A fungus is a member of a large group of eukaryotic organisms (Bryden‚ 2007).Fungi is considered important microorganisms‚ because of its beneficial role in human life; it has been used for many purposes such as in medicinal manufacturing‚ industries‚ food production‚ and plant nutrient supplements. Also it has role in cycling of carbon in the atmosphere‚ since it is main decomposers of organic matter (kavanagh‚ 2011). Fungi can be found naturally everywhere in the environment;
