Describe How Antimicrobial Agents Are Used To Control The Growth And Spread Of Bacteria

Chemical antimicrobial agents are chemical compounds capable of either inhibiting the growth of microorganisms or killing them outright. Those which are taken internally to alleviate the symptoms of or promote healing from disease are called chemotherapeutic drugs, and among these is a class of compounds called antibiotics. In order for a chemotherapeutic drug to be classed as an antibiotic, it must be produced by a microorganism such as bacterium or fungus or at least derived from a chemical produced by one. It must also be capable of killing or inhibiting the growth of other microorganisms and of doing so when taken in very small quantities.

Antibiotics either stop the bacterial cell from reproducing or kill the cell. They can disrupt the bacteria by deterring

The aim of this investigation was to find out which antiseptics were most effective at preventing the growth of bacteria.

Antibiotics:- antibiotics are medication which destroy or slow down the growth of bacteria, they are used to treat infections which are caused by bacteria. Most of the time the body’s immune system can fight off bacteria but in cases in which the body cannot antibiotics are used to destroy them. Antibiotics are either given orally, applied to the skin in ointment form or injected, this all depends on the type of infection the body is currently trying to fight off, for example skin infections are treated with ointment, oral antibiotics are used to fight of moderate infections and injective antibiotics are most commonly used in

Chapter 12 caught my attention because it informs you how infections develop into humans and types of agents to stop the infection. Infection and pathogens are created by microorganisms that enter the body. Microorganisms that can cause this are bacteria, viruses, fungi and parasites. These microorganisms can enter through your nose, mouth or skin so it is recommended to always wash your hands and receive vaccinations. Antibiotics are not as effective like it was back in the days, because microorganisms learned to be resistant to it. There is antibacterial, antiviral and antituberculosis agents to control microorganisms. Antibacterial agents destroys microbes and prevent it from multiplying. Antituberculosis are agents that treat diseases that

Not Washing hands frequently especially after dealing with any bodily fluids. Staff not staying at home if they are sick. Use a tissue, or cough and sneeze into your arm, not your hand. Turn away from other people. Open wounds not being covered especially on the hands. The incorrect use of PPE or the none use of PPE. Sharing personal items between each other. Incorrect food prep and storage.

The Kirby-Bauer disc diffusion method was used to examine sensitivity of antimicrobial agents, it fast and simple way to find an antibiotic to use for a treatment of some type of infection. This method uses a plate that has been cover with the testing bacteria and small disc covered in the antibiotic to see if the bacteria is able to around the disc, it will make an even circle around the disc which is the zone of inhibition. This zone of inhibition diameter can be measured and compared to the interpretation chart to find the antibiotic sensitivity or resistance. When the zone of inhibition is very small or nonexistent this shows that bacteria is resistant to the antibiotic and will not work against this bacterial infection. If the zone is

Antibiotics is drugs that kill or slow the growth of bacteria. Antibiotics used for treat animals that are sick and prevent from being sick. It is also uses to help growth.

An antibiotic is a type of medicine that completely destroys microorganisms (microscopic, single celled life forms) and stops them from growing. An antibiotic named penicillin is one of the most used antibiotics.

I must take all reasonable steps to ensure that the PPE is returned, once worn to the appropriate location and that the items are not removed from the workplace.

The Effects of Antibiotics on Bacterial Growth Biology II 1996 Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic, measuring 1 micron in length. However, colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. There are many divisions and classifications of bacteria that assist in identifying them.

Examples of antibiotics that are commonly used in infection treatment include: gentamycin, tetracycline, streptomycin, and carbenicillin

Modern-day advances have allowed scientists to develop methods to control pathogens. The more common methods include the use of antiseptics, antibiotics, and vaccines. By definition, antiseptics are chemicals used to kill pathogens. A few widespread antiseptics include soap, vinegar, and rubbing alcohol. Antiseptics are primarily used for the external destruction of pathogens, while antibiotics and vaccines target internal pathogens. Nevertheless, there are and can be difficulties concerning the use of antibiotics. “As antibiotic use has become more common, antibiotic-resistant bacteria have evolved.” This resistance due to evolution is called antibiotic resistance. It results in the antibiotics having no effect whatsoever on the bacteria, rendering the antibiotics useless. When antibiotic resistance occurs, scientists must resume their search to create a new medicine to can kill the mutant bacteria.

Antibiotics have played a major role in our society thanks to Sir Alexander Fleming's careful observations in 1928. Without it, many lives would be in danger due to infectious diseases. Antibiotics are chemical substances produced by various species of microorganisms and other living systems that are capable in small concentrations of inhibiting the growth of or killing bacteria and other microorganisms. These organisms can be bacteria, viruses, fungi, or animals called protozoa. A particular group of these agents is made up of drugs called antibiotics, from the Greek word anti ("against") and bios ("life").

Antibiotics - effective against bacterial infections, only; overuse of antibiotics is responsible for the emergence of a super strain of bacteria, can cause resistance to all antibiotics
