Safety in a microbiology laboratory is important in the prevention of infection that might be caused by the microorganisms being studied. This laboratory does not require the use of virulent human pathogens. However‚ many types of microorganisms are potentially pathogenic. This means that‚ although they would not cause disease in a normal healthy host‚ they might possibly do so if a large enough quantity of the microbes came into contact with a compromised host‚ such as by wounds and cuts.

Labset Five Worksheet 1. List five environments where you are likely to find microbial growth: Lakes‚ soil‚ oceans‚ tundras‚ deserts 2. How do microbes contribute to soil fertility? The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your

ASEPTIC TECHNIQUES AND SOURCES OF MICROBIAL CONTAMINATION. Introduction The spread of infections has come to a point where it has become catastrophic. Aseptic technique is the method used to prevent contamination of infections. It is widely used in hospitals‚ pharmacy‚ and pharmaceutical industries and in laboratories. Different establishments have come up with more ways to improve infection control. In hospitals health care acquired infections are costing the NHS £1 Billion a year and

I did not learn my communicating skills until I took my microbiology class. I had to do a project on sexual transmitted diseases (STD) and it required meeting after class. Being shy and not confident enough‚ I didn’t want to meet my group. Dr. Nande called me one day because some of my group partners complained to him. I stood in front of him looking down nervously on what he was going to say. He read my body language and just said that I can either tell him what the problem is or I can take a zero

TRIPLE SUGAR-IRON AGAR TEST Triple sugar-iron (TSI) agar test- designed to differentiate among the different groups or genera of the Enterobacteriaceae‚ which are all gram-negative bacilli capable of fermenting glucose with the production of acid a. Differentiation is made on the basis of differences in carbohydrate fermentation patterns and hydrogen sulfide production. To facilitate observation of carbohydrate utilization patterns- TSI agar slants contain lactose and sucrose (1%) concentrations

c) In what ways did the understanding of the treatment of disease change in the years 1860-1945? The treatment of disease changed dramatically in the years 1860-1845 due to the changes of how people understand it‚ how each discovery such as Pasteur’s opens new doors‚ leading to other discoveries such Koch’s identification of germs‚ the magic bullet and discovery of penicillin. this has help society to understand the causes of disease‚ and the ways to tackle it. These discoveries began in
