Isolation of Bacteria in our Physical Environment Introduction: The purpose of the lab is to apply what has been learned so far in Microbiology‚ and use it to collect and examine microbial species from the physical environment. The physical environment around the lab will be utilized to find out the variety of different microbial species growing in and around the lab. This investigation will help in preparation for the individual projects that will be done at the end of the semester. Materials

Access HP&S Biological Concepts Microorganisms and Biotechnology Use of Aseptic Technique Introduction Microorganisms (microbes) such as prokaryotes are the oldest life form that we know. Various forms have been discovered‚ not only to survive‚ but to thrive in the most hostile and extreme of environments and have been named extremophiles and various types of microbes are found in every niche of ecology. Due to their resilience and success at sustaining their existence‚ it has proven to

INTRODUCTION This scientific report is to discuss the results of an experiment being conducted on the effect that antibiotics have on the growth of bacteria. This will be done through the use of microbiology. Microbiology is a science in the department of biology‚ particularly microorganisms. These include; bacterium‚ fungi‚ protozoa‚ algae and viruses. This is an important subject to study as microorganisms can be found everywhere‚ covering all matters of different surfaces even including the human

13 Principle of Asepsis The 13 Principles of asepsis is a basic knowledge that a nursing student should always remember when preparing for an operation and when working during an operation. Since Asepsis means the absence of pathogens‚ these 13 principles of asepsis is not only applicable when there is an operation but it should be observe in situations where there is a need to maintain the sterility of certain articles and to maintain a sterile environment. 13 Principles of Asepsis 1.

Reflective Log – Aseptic Technique In this reflection I am going to discuss a procedure that I have carried out whilst I have been on placement and the importance of infection control using the Aspetic Non Touch Technique (ANTT). The procedure I am going to discuss is a dressing change to a leg ulcer which took place during a routine home visit with the community nurse. I am going to use Gibbs Model of Reflection (1988)‚ to reflect on the experience and evaluate my thoughts and feelings of the procedure

Aseptic Technique & Culturing Microbes Questions A. What is the difference between a bactericidal and bacteriostatic agent? What is the difference between sterilization and disinfection? Control of growth refers to the prevention of growth of microorganisms. This control is affected in two basic ways: by killing microorganisms or by inhibiting the growth of microorganisms

the ‘Aseptic Technique’. For procedures such as pressure sores‚ leg ulcers‚ simple grazes’ removing drains or sutures‚ the ‘clean technique’ is used which is a modified aseptic technique and aims to avoid introducing micro organisms to a susceptible site and also to prevent cross contamination to patients and staff‚ it differs from an aseptic technique‚ as the use of sterile equipment and the environment are not as crucial as would be required for asepsis (Gough 2009). The Aseptic technique is one

Introduction: Microbes‚ also called microorganisms‚ are minutes living things that individually are usually too small to be seen with the unaided eye. The group includes bacteria‚ fungi (yeast and molds)‚ protozoa and microscopic algae. It also includes viruses‚ those noncellular entities sometimes regarded as straddling the border between life and nonlife. People tend to related these microbes only with major disease such as AIDS‚ uncomfortable infections‚ or such common inconveniences as spoiled

Techniques for Isolation of Pure Cultures Objective : i. To perform the spread plate and the streak plate inoculation procedure for the separation of the cells of a mixed culture so that discrete colonies can be isolated. ii. To prepare a stock culture of an organism using isolates from the mixed cultures prepared on the agar streak-plate and/or the spread plate. Introduction : In order to be able to adequately study and characterize a certain microorganism‚ microbiologists need to separate
