Biological Substances And Its Effects On Bacterial Infections

In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.

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

Antibiotics, composed of microorganisms such as streptomycin and penicillin, kill other infectious microorganisms in the human body. At one point, antibiotics were considered to have “basically wiped out infection in the United States”, but due to their overuse and evolutionary

The inhibition of cell reproduction caused by Chloramphenicol takes place through interference with protein synthesis. An experiment was conducted in order to determine which antibiotics are most effective in inhibiting bacterial growth. First, the different bacteria were placed on agar

The disclosure by Alexander Fleming of penicillin opened up a totally new time of chemotherapy. Antibiotics are the chemotherapeutic specialists that kill or inhabit the development of microorganisms. These substance operators are utilized to treat malady by wrecking pathogenic microorganisms or restraining their development at focus sufficiently low to enough to avoid undesirable harm to the host (Dafale et al., 2016).

These mutations, no matter what process that has led to their occurrence, block the action of antibiotics by interfering with their mechanism of action (1). Currently, antibiotics attack bacteria through one of two mechanisms. In both mechanisms the antibiotic enters the microbe and interferes with production of the components needed to form new bacterial cells. Some antibiotics act on the cell membrane, causing increased permeability and leakage of cell contents. Other antibiotics interfere with protein synthesis in cells. They block one or more of the steps involved in the transformation of nucleic acids into proteins.

Antibiotics are chemical substances that can kill or inhibit the growth of infectious microorganism. They could be naturally occurring or synthetic in a laboratory. Each type of infection has its therapeutic course duration which should be completed neither reduced nor overused. The long term use of antibiotics may harm the host. In addition to the impact of antibiotic on infectious organism, they can affect the non-infectious bacteria. These effect on non-infectious bacteria depend on the type of used antibiotic, its mechanism of action and resistance level among community. Different antibiotics affect the normal gut bacteria in diverse ways depending on several the antibiotic spectrum of activity, dose and duration of therapeutic course, administration route and characteristics of the

For over 50 years, antibiotics have been used to do many useful things. During the World War II, it has been extremely useful especially to cure infectious wounds and treat diseases. However, people wonder how antibiotics are made or how it works. Well, it may be a shock but, bacteria actually makes antibiotics up. This one celled organism can be found everywhere and on everyone on the globe.

Antibiotic have been essential tools for fight against bacterial infections since the early 20th century. Antibiotics fall under different groups based on the method of treatment. There are basically 3 main groups of antibiotics based on their mechanism of action, i.e Cell wall Disruptive Antibiotics like beta lactams, Protein synthesis inhibitors and nucleic acid

Antibiotics have been treating diseases and infections for a very long time. During ancient times many different types of things were used such as moulds, plants, frog bile and more. However, it was not until modern times when antibiotics started to become more commonly known and used. The discovery of penicillin by Sir Alexander Fleming marked a new pathway for modern antibiotics. Since then antibiotics have been used constantly for colds, medical procedures, saving millions of lives. However, they are being misused and overused, making them less effective as the bacteria they are fighting develop resistance. This is a global concern that many people still

Professor Laura Piddock, Professor of Microbiology at the University of Birmingham, said: “The screening tool developed by these researchers could be a ‘game changer’ for discovering new antibiotics as it allows compounds to be isolated from soil producing micro-organisms that do not grow under normal laboratory conditions.”

Many human illnesses are caused by infection with bacteria, these microorganisms must gain access to the body. Bacteria reproduce by splitting in two. Many bacterial infections can be treated successfully with antibiotics as Cephalosporins which are derived from the parent compound cephalosporin C, which is a natural antibiotic produced by a strain of the mold Cephalosporium acremonium. The use of antibiotics has a very considerable impact on modern medicine for the ability of doctors to treat bacterial infections that threaten life. The antibiotics are widely distributed in the nature, where they play an important role in regulating the microbial population of soil, water, sewage and compost. From the

The aim of this experiment was to find bacteria within the soil that produce antibiotics that are effective against the ESKAPE pathogens. We found that the CFU/g of the bacteria cultured were largest when they were found close to or directly within the soil of plants likely due to the nutrients they provide. Of the thirty-three bacteria found to produce antibiotics, sixteen were found to be effective against gram positive bacteria, fifteen were found to be effective against gram negative bacteria and one was found to be effective against both. Using gel electrophoresis, we identified that the 16s rRNA gene that was enhanced through PCR was about 1400 base pairs long. Furthermore, through gram staining, we identified that sixteen of the antibiotic

Antibiotics is the chemical substances which derived from living organisms that are capable to inhibit or kill the other living organism’s life process.

However, the usage of antibiotics in agriculture is a contributor to the continual growing issue of antibiotic resistance. According to the World Health Organization (WHO), “[a] post-antibiotic era – in which common infections and minor injuries can kill… is instead a very real possibility for the 21st Century” (World Health Organization) because of antibiotic resistance.
