Bacteria And Its Effects On Bacterial Populations

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:- 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

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

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 like ciprofloxacin and doxycycline kill the bacteria or inhibit growth of the bacteria that causes eventual death.

In doing research for an example of natural selection, I came across antibiotic resistant bacteria. This has become one of the biggest threats to the healthcare community and Center for Disease Control. Through the use of antibiotics in treatments that are not necessarily bacterial infections, as well as the over use and misuse of antibiotics, bacteria have evolved in ways making the antibiotics used against them useless. If a bacteria manages to survive through a dose of an antibiotic, they are capable of mutating and can transfer their DNA to other bacteria. The new bacteria multiply quickly and spread to other parts of your body or outside of your body to a new host. Once the bacteria have mutated and its DNA has been transferred to

Bacteria can be a scary thing, but some people do not even know what bacteria is but doctors have created antibiotics to destroy it. “Many people are unaware what bacteria are and how antibiotics control them.”(Voss, Bristol) Basically bacteria a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease. Antibiotics are used to destroy bacteria, but if a person is prescribed too many antibiotics they may become immune to antibiotics forever and have to live without a strong immune system. Antibiotics attacks bacteria by preventing it from building a wall to defend itself from the body's immune system. So the body’s immune system can easily kill the bacteria.

Antibiotic should kill bacteria.Antibiotic-resistant infect two million people each year.”Some bacteria have developed resistance to antibiotics that were once commonly used to treat them.”

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.

Antibiotics are medicines used to treat infections or diseases caused by bacteria. Antibiotics work by blocking vital processes in bacteria, killing the bacteria, or stopping them from multiplying. This helps the body’s natural immune system to fight the bacteria infection. Antibiotics do not affect the quality of a beef product. There is an upcoming issue that needs to be addressed about antibiotic resistance. Antibiotics differ in the types of bacteria they work against. Antibiotics that affect a wide range of bacteria are called broad spectrum antibiotic.

Frequent antibiotic use over long periods of time puts selective pressure on bacteria, and causes resistance to spread. When an antibiotic is used to treat a typical bacterial infection, most bacteria are killed. Sometimes, however, a bacterium with an advantage lives. This bacterium can then reproduce and pass its advantage on, creating many more antibiotic resistant bacteria.​ Sometimes in medicine, antibiotics are used too often or incorrectly, which can cause resistance to spread faster than it would

Antibiotics can be divided into two categories: Bactericidal or Bacteriostatic. Bactericidal antibiotics directly kill the micro-organisms, and depending on the amount given, the bacteria will not recover after administration of the antibiotic is ceased. Bacteriostatic antibiotics prevent growth of the bacteria, by targeting proteins that are involved in reproduction. Once the bacteriostatic antibiotic is removed, population numbers usually increase again.

Bacteria are microorganisms that are well known to be the major cause of why people get ill. Many of these microorganisms in the world are pathogenic by nature but are treatable by a wide number of antibiotics, some are normal flora in the body, and others are opportunistic ones. In recent years, scientists formulated specific antibiotics that would eliminate and eradicate these pathogenic types of microorganisms, but there are still some microorganisms that are present today that is hard to eliminate due their capability to tolerate antibiotics.

Infection, as defined by Encyclopedia Britannica (2011), is the invasion and multiplication of different pathogenic microorganisms in the body-such as fungi, bacteria and viruses- the body’s reaction to it and the defense mechanisms it activates to counter these pathogens or the toxins they produce. Infections can range from simple to complex ones that can be fatal or debilitating, but because of the continuous researches and studies to protect the human race, antibiotics were discovered. Antibiotics inhibit the release of toxins of these microorganisms or simply fight against them to eliminate the harmful effects they bring about. Luckily, before one can resort to the use of antibiotics that can also have side effects on the body, there

Bacteria are found everywhere around us and many of which are beneficial to the environment and humans, assisting in protecting the biodiversity of ecosystems within an urbanized environment. This paper aims to determine the role and functions of bacteria found within the ponds of Centennial Park in relation with other bacteria and eukaryotes. This was achieved through the process of traditional and modern microbiological techniques of gram staining, biochemical tests and 16s rRNA analysis of bacterial DNA to help classify the different bacterial isolates. Heterotrophic proteobacteria were mainly found which countered algal blooms within the pond by reducing nutrient levels, assisted in bioremediation, decomposed debris and assisted in
