of two different topical chemicals on growing bacteria over the course of a week. Bleach‚ water‚ hand sanitizer and hand soap were all variables used to observe the effects of the bacteria swabbed from my palm and fingers. Bleach has been the go to product for killing germs and it is because of the similar effects it has with high temperature on the proteins in bacteria. I hypothesized that bleach would be the most efficient way for killing the bacteria over hand sanitizer and hand soap. Methods I

CONTENT A. BRIEF PRESENTATION OF THE CASE B. POINT OF VIEW I. INTEGRATED SCIENCE(Interaction: Environment and organism) II. COURSE PAPER: CASE STUDY Bacteria constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length‚ bacteria have a wide range of shapes‚ ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear onEarth‚ and are present in most habitats on the planet‚ growing in soil‚ water‚ acidic hot springs‚ radioactive

Superbugs are becoming a big problem in the world‚ but what are superbugs? Superbugs is a bacteria that becomes resistant to antibiotic drugs they carry genes that are resistant to antibiotic drugs and cannot stop the bacteria from multiplying (Staff 1). You might know of superbugs by the term multidrug-resistant bacteria. This mostly happens when people overuse antibiotics and their body becomes immune to those drugs. In very severe cases people with extremely weak immune systems usually die if

The Relation of Antiseptics and Bacteria Growth Purpose: To explore the effectiveness of different levels of concentration of antiseptic and antibacterial products’ prevention of bacterial growth. Question: Amongst common household products‚ which antiseptic and level of concentration is more effective at inhibiting the growth of bacteria? Introduction: Antiseptics are antimicrobial substances used on living tissue to reduce the possibility of infection‚ putrefaction or sepsis. The word “anti”

"TB") is a disease caused by the bacteria Mycobacterium tuberculosis which infects white blood cells. It mainly infects the lungs‚ although it can affect other organs as well. TB is spread through the air from one person to another. The bacteria are put into the air when a person with active TB disease of the lungs or throat coughs or sneezes. People nearby may breathe in these bacteria and become infected. When a person breathes in TB bacteria‚ the bacteria can settle in the lungs and begin

Introduction: Bacteria need specific living conditions to survive. The ideal conditions for bacterial growth is a warm‚ dark‚ and damp environment. This provides the maximum effectiveness for bacterial growth. The areas in our school that contain the most bacteria would be the water fountains because the bacteria from our mouths drop off on to it when we drink from it‚ and because water fountains are not regularly washed in comparison to weight equipment. Water fountains also provide a warm damp

The world is exist with germs of all kinds especially viruses and bacteria. Most of the time human bodies do a wonderful job of fending off these microbes. This sort of self-defense is due to the immune system‚ which detects any pathogen also known as disease-causing agent and attacks it with immune foot soldiers including macrophages‚ lymphocytes and phagocytes. Specifically‚ over 700 different strains of bacteria have been discovered in the human mouth‚ though most people are only host to 34 to

is effective for single cell organisms. Example: Glycolysis. Antibiotic resistance: Resistance of a microorganism to survive through the exposure of an antibiotic. Resistance is generally due to a genetic mutation of a bacteria‚ or evolutionary stress. A bacteria with many resistance genes may be referred to a superbug‚ or super bacterium. Archaea: Single celled organisms‚ who are a part of 1/3 domains of life. Contains no nucleus or organelles. Can survive in extreme conditions

biofilms When bacteria is threatened by antibiotics treatment that can kill them‚ or when a strong immune system responses to bacteria and produce cytokines or other agents to eliminate it from the body‚ Bacteria has the choice of either staying as individual and die or change their form to make biofilms. Biofilms are communities or bacteria binds together in large groups and make a sticky mesh to make themselves resistant against antibiotics. Some drug that can kill single bacteria will not be able

Did you know‚ food poisoning has increased dramatically in the last ten years? This makes it much more important for vigilance by food businesses. Since 1965 the cases of food-borne illness has increased from 20‚000 to just short of 100‚000 now. There has been no single reason identified to why this number has increased‚ but this could be because of: Changes in eating habits‚ a greater reliance on re-heated food. Eating out is much more popular now‚ so more people are aware of food hygiene‚ therefore
