The Effects Of Antibiotics Bacterial Growth - 901 Words

Randhawa 1 Zorawar Randhawa Mrs. Eideh Honors Biology 8 June 2015 Effects of Antibiotics Bacterial Growth 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. When considering the pH level, bacteria are classified as either acidophiles (acid-loving), neutrophiles (neutral ph range), or alkaliphiles (alkali-loving). The one that causes disease in humans would be the neutrophiles, which have an ideal pH range of 5.4 to 8.0. There are exceptions, however, like Alcaligenes faecalis and Vibrio choleae, which are both alkaliphiles and can infect humans. There are physical and nutritional factors that affect bacterial growth in the environment. Sterilization is needed to keep an environment free from bacterial growth. Failure to sterilize bacterial growth in our food products today leads to the unfortunate consequence of food poisoning. Randhawa 2 During lag phase, bacteria adapt themselves to growth conditions. It is the period where the individual bacteria are maturing and not yet able to divide. During the lag phase of the bacterial growth cycle, synthesis of RNA, enzymes and other molecules occurs. The log phase (sometimes called the logarithmic phase or the exponential phase) is a period characterized by cell doubling.[3] The number of new bacteriaShow MoreRelatedThe Effects of Antibiotics on Bacterial Growth1355 Words   |  6 PagesThe 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. The first two types of bacteria are archaebacteria and eubacteria. Both groups have common ancestors dating to moreRead MoreAntibacterial Antibiotics And Its Effects On The Growth And Production Of Bacterial Infections1368 Words   |  6 PagesAntibacterial antibiotics are a substance present in fungi, which inhibits the growth and production of bacterial infections. The discovery of the first antibiotic, penicillin, was a turning point in medical history, as illnesses that were once perceived as difficult to treat or even fatal, now had a possible treatment. After the discovery of penicillin, the misuse and overuse of antibiotics become common in many different professions. This has resulted in bacteria becoming less easily detected dueRead MoreStaphylococcus Aureus ( Mrsa )905 Words   |  4 Pagesaureus (MRSA) is a bacterial ‘staph’ infection that is resistant to the use of certain antibiotics. ß-lactams, penicillin-like antibiotics that has become a resistant, has become a characteristic of MRSA since its discovery in England in the 1960s and later in the USA around 1968. Due to overexposure to the antibiotics, strains of MRSA have become resistant through the evolution of the bacterial cells. This, eventually, led to insensitivity to the antibiotic’s agent fighting effects. The ability ofRead MoreLab Report On The Lab759 Words   |  4 Pagesunderstand the effects of the different antibiotics (CAM, Amp, and Strep) on the bacteria growths. This lab also allowed the lab students to understand the importance of staining, bright-field microscopy, spectrophotometry, and the fluorescence microscopy. The hypothesis for this lab would be that for the mixture without the antibiotic would have an increase in the absorbance rate. The mixtures with the antibiotics (CAM, Amp, or Strep) would affect the formation of new bacterial cells that wouldRead MoreEffectiveness Of Bacitracin, Gentamicin And Chloramphenicol On The Growth Of Escherichia Coli1236 Words   |  5 PagesEffectiveness of bacitracin, gentamicin and chloramphenicol on the growth of Escherichia coli Introduction: Escherichia coli (E. coli) is a bacterium commonly found in the digestive system of humans and animals. Although it is mainly harmless and helps promote a healthy digestive system, some strains can be pathogenic and cause illness such as diarrhea, urinary tract infections, respiratory infections and even pneumonia. What makes E. coli pathogenic is the release of a toxin called Shiga. TheseRead MoreAntibiotics Are Antibiotics Used For?1198 Words   |  5 PagesAntibiotics What are antibiotics used for? Antibiotics are used to fight infections which are caused by bacteria. They are not effective against viruses. What are antibiotics? Antibiotics can either be bactericidal or bacteriostatic. Bactericidal antibiotics act to kill bacteria and bacteriostatic act to inhibit and slow down the growth or bacteria. By doing this the antibiotics allow the hosts defence mechanisms to kill the bacteria or fight infection. Where do antibiotics come from? Lead compoundsRead MoreInhibition Of Various Targets On Bacteria Cells Essay1084 Words   |  5 PagesInhibition of various targets in bacteria cells has long been a strategy for developing new antibiotics. Within a bacteria cell, there are nearly endless potential targets for inhibition that may interrupt cell metabolism, replication, synthesis of membrane components, etc. However, the rise of antibiotic resistance means researchers are continually searching for new targets or ways to make old targets viable again. For this reason, novel narrow-spectrum inhibitors are of great interest, especiallyRead MoreMethods And Methods Of Antibiotic Sensitivity Testing1524 Words   |  7 Pagesbriefly how antibiotic sensitivity testing is carried out in the clinical laboratory providing examples of both manual methods and automated methods (include advantages and disadvantages of methods discussed) Introduction An antibiotic is a chemical produced by a microorganism that kills or inhibits the growth of another microorganism. Therefore, the big task of microbiology laboratory is to determine how effective an antibiotic is through antimicrobial susceptibility testing of bacterial isolatesRead MoreModern Medicine And Treatment Of Antibiotics1361 Words   |  6 PagesModern medicine relies on antibiotics to save lives through antibiotic treatment of severe infections and the performance of medical and surgical procedures under the protection of antibiotics. However, we have not kept pace with the ability of many pathogens to develop resistance to common antibiotics. The most common use of antibiotics is in the agricultural industry, and within the agricultural industry the most common antibiotic is tetracycline (Sanramaria, 2011; Mathews, 2013). TetracyclineRead MoreThe Overuse Of Antibiotics And Antibiotics1466 Words   |  6 PagesThe overuse of antibiotics has been a problem for well over a decade. This misuse leads to many nonvisible problems arising within the human population. As the use of antibiotics increases, the number of antibiotic resistant bacteria also increases. When bacteria become resistant to an antibiotic, another antibiotic must be used to try and kill it and the cycle becomes vicious. Michael Martin, Sapna Thottathil, and Thomas Newman stated that antimicrobial resistance is, â€Å"an increasingly serious threat
