In the microbiology lab we use aseptic technique to:
- Prevent contamination of the specific microorganism we are working with.
- Prevent contamination of the room and personnel with the microorganism we are working with.
Why is aseptic technique so important?
Aseptic techniques in science and health care are important to keep infectious microorganisms from sterile surfaces or tissues. In health care aseptic techniques deter infection when working with patients, while the same techniques prevent contamination of tests or experiments in laboratory work.
What are the goals of aseptic technique?
Aseptic technique is a procedure used by medical staff to prevent the spread of infection. The goal is to reach asepsis, which means an environment that is free of harmful microorganisms.
What is meant by aseptic techniques?
Aseptic technique refers to the procedure used to avoid the introduction of pathogenic organisms into a vulnerable body site or invasive device. The principle aim of an aseptic technique is to protect the patient from contamination by pathogenic organisms during medical and nursing procedures.
What are some spreading techniques in microbiology?
- Pour Plate Technique
- Spread Plate Technique
- Streak Plate Technique

Why is proper aseptic technique important in microbiology quizlet?
What is the importance of using aseptic technique in a Microbiology lab? It is important because it keeps infectious microorganisms from sterile surfaces or tissues. It prevents contamination of tests and experiments.
What is aseptic technique and why is it important?
Aseptic technique, a method used to prevent contamination with microorganisms, is recommended by the evidence-based guidelines for all instances of insertion and care of central venous catheters.
Why aseptic techniques are important when culturing cells?
Aseptic technique prevents contamination of cell culture and reagents from microorganisms in the environment.
What is the most important aspect of aseptic technique?
Infection prevention and control In turn, aseptic technique minimises the risk of contamination of key sites, protects patients from their own pathogenic microorganisms, and ultimately, reduces the risk of infection transmission.
Why do we use aseptic techniques?
The way healthcare providers use aseptic techniques before, during , and after your procedure help protect you from infection. When you need surgery or other procedures that require aseptic technique, you’re already vulnerable to infections. You need your immune system to be at its strongest to heal.
Where do healthcare workers use aseptic technique?
Healthcare workers use aseptic technique in surgery rooms, clinics, outpatient care centers, and other health care settings.
What are the barriers used in aseptics?
Some barriers used in aseptic technique include: Sterile barriers are those that have not touched a contaminated surface. They’re specially packaged and cleaned items.
Why is it important to use clean techniques?
The goal of the clean technique is to reduce the number of germs whenever possible. Clean techniques are important for all healthcare providers and their patients because they prevent infections every day. Examples of clean techniques include washing hands and putting on clean gloves when needed.
What is the term for bacteria that are harmful?
Bacteria are everywhere, and some are good for us while others are harmful. Bacteria, viruses, and other microorganisms that cause disease are called pathogens. To protect patients from harmful bacteria and other pathogens during medical procedures, healthcare providers use aseptic technique. Aseptic technique means using practices ...
What are the four main aspects of the aseptic technique?
According to The Joint Commission, there are four chief aspects of the aseptic technique: barriers, patient equipment and preparation, environmental controls, and contact guidelines . Each plays an important role in infection prevention during a medical procedure.
How to maintain sterile environment?
Maintaining a sterile environment requires keeping doors closed during an operation. Only necessary health personnel should be at the procedure. The more people present, the more opportunities for harmful bacteria to cause contamination.
Why is aseptic technique important?
Since the goal of a biologist is to grow microorganisms or eukaryotic cells without the introduction of extraneous organisms, aseptic techniques are crucial for accurate and meaningful experimentation. One should always remember that a completely sterile working environment does not exist.
What is aseptic technique?
Aseptic technique is a set of routine measures that are taken to prevent cultures, sterile media stocks, and other solutions from being contaminated by unwanted microorganisms (i.e., sepsis). While such actions are sometimes called “sterile technique,” that terminology is appropriate only in reference to preventing the introduction ...
How to avoid cross contamination?
Avoid pouring media and reagents directly from bottles or flasks. Use sterile glass or disposable plastic pipettes and a pipettor to work with liquids, and use each pipette only once to avoid cross contamination . Do not unwrap sterile pipettes until they are to be used. Keep pipettes at the work area.
What is a sterile graduated pipette?
Sterile graduated or dropping (Pasteur) pipettes are used to transfer cultures, sterile media and sterile solutions. Remove the pipette from its container/ wrapper by the end containing a cotton wool plug, taking care to touch as little of the pipette as you need to take a firm hold. Fit the teat.
What are some examples of aseptic techniques?
Examples of aseptic technique are: Cleaning and disinfecting lab surfaces prior to use. limiting the duration that cultures or media are uncapped ...
How to avoid breathing on cultures?
There are some general rules to follow for any aseptic technique. Close windows and doors to reduce draughts and prevent sudden movements which might disturb the air. Make transfers over a disinfected surface.
How to make a lab bench sterile?
Probably the easiest way to create a relatively sterile environment on the laboratory bench is by using a simple gaspowered burner.
What is aseptic technique?
A fundamental and important laboratory skill in the field of microbiology. Microbiologists use aseptic technique for a variety of procedures such as transferring cultures, inoculating media, isolation of pure cultures , and for performing microbiological tests. Turn off bunsen burner or hot plate when not using.
Why is a syringe selective?
It can be selective due to nutrients, P.H. and antibiotics.
What is the term for when one organism prevents other organisms from growing in its vacenaty?
boiling water, using Bunsen burner, autoclave machine, wash hands, sterilize area, don't place items down on a non-sterile surface. Antagonism. when one organism prevents other organisms from growing in its vacenaty. Light microscope. is an instrument that is used to see organisms that are not seen by the naked eye.
How is chemotaxity achieved?
Chemotaxity and true motility is achieved by rotation of flagella.
Does a microscope have a visual?
has no visual on the microscope it's self. it concentrates light source into a cone of light that passes through diaphragm.
