Q. What is the protective structure of bacteria?
Bacterial cells are generally surrounded by two protective coverings: an outer cell wall and an inner cell membrane. Certain bacteria, like the mycoplasmas, do not have a cell wall at all. Some bacteria may even have a third, outermost protective layer called the capsule.
Q. What do bacteria protect?
Gram negative bacteria are surrounded by a double membrane that forms a highly effective protective barrier and makes the cell far more resilient to antibiotics.
Q. What are the structures of bacteria?
Structurally, there are three architectural regions: appendages (attachments to the cell surface) in the form of flagella and pili (or fimbriae); a cell envelope consisting of a capsule, cell wall and plasma membrane; and a cytoplasmic region that contains the cell chromosome (DNA) and ribosomes and various sorts of …
Q. What are the three structural forms of bacteria?
Individual bacteria can assume one of three basic shapes: spherical (coccus), rodlike (bacillus), or curved (vibrio, spirillum, or spirochete). Considerable variation is seen in the actual shapes of bacteria, and cells can be stretched or compressed in one dimension.
Q. What is the most common form of bacterial growth?
Batch culture is the most common laboratory growth method in which bacterial growth is studied, but it is only one of many….Phases
- During lag phase, bacteria adapt themselves to growth conditions.
- The log phase (sometimes called the logarithmic phase or the exponential phase) is a period characterized by cell doubling.
Q. What are the two things you should never do when using disinfectants?
What are two things to NEVER do with disinfectants? 1- Never let quats, phenols, bleach or any other disinfectant come in contact with your skin. If you do-Rinse, then wash area with soapy water and rinse again. Dry thoroughly.
Q. What are 2 methods of disinfection?
Generally, two methods of disinfection are used: chemical and physical. The chemical methods, of course, use chemical agents, and the physical methods use physical agents. Historically, the most widely used chemical agent is chlorine.
Q. Which is the most common salon disinfectant?
Sodium hypochlorite (household bleach), is an effective disinfectant for all uses in the salon.
Q. What is the most common bacteria found on Salon implements?
Bacilli are short rod-shaped bacteria. They are the most common bacteris and produce diseases such as tetanus (lockjaw), typhoid fever, tuberculosis, and diphtheria. Bacilli and spirilla are both motile and use slender, hairlike extensions, known as flagella or cilia, for locomotion.
Q. What are acceptable disinfectants in a salon environment?
Other appropriate salon disinfectants include: 10 percent bleach solution (1 part bleach to 9 parts water) Isopropyl alcohol – 70-90 percent solution. Ethyl alcohol – 70-90 percent solution.
Q. What are the three levels of disinfection?
There are three levels of disinfection: high, intermediate, and low.
Q. What are some sterilizing tools?
Autoclaves, clean-in-place (CIP) and sterilization-in-place (SIP) systems, dry heat sterilizers and ovens, steam sterilizers, media sterilizers, and UV chambers all work to sterilize equipment and supplies.
Q. What are two infection control techniques in a salon?
Wearing sterilised gloves to protect against chemicals and passing of germs during treatments. Wearing an apron to protect against chemical/spillages. Protective glasses during light therapies or lazer treatments.
Q. What are the 5 basic modes of transmission of infection?
The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.
Q. What are hospital standard precautions?
Standard precautions are a set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin (including rashes), and mucous membranes.
Q. What are the methods of infection control?
Infection Control Basics
- Disinfection and sterilization.
- Environmental infection control.
- Hand hygiene.
- Isolation precautions.
- Multidrug-resistant organisms (MDRO)
- Catheter-associated urinary tract infections (CAUTI)
- Intravascular catheter-related infection (BSI)
- Organ transplantation.
Q. How many types of infection are there?
Millions of different viruses may exist, but researchers have only identified about 5,000 types to date.
Q. What is the lowest level of infection control?
The field of infection prevention describes a hierarchy of removal of microorganisms from surfaces including medical equipment and instruments. Cleaning is the lowest level, accomplishing substantial removal. Disinfection involves the removal of all pathogens other than bacterial spores.
Q. What are the four elements in the chain of infection?
No matter the germ, there are six points at which the chain can be broken and a germ can be stopped from infecting another person. The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.
