Antibiotics Effects On Growth Rate Of Bacteria Escherichia...

Antibiotics Effect on Growth Rate Antibiotics are important for the treatment of bacterial infections, and it is therefore important to know how different antibiotic works in different contexts. Different kinds of bacteria are affected to different degrees by different antibiotics, and it may therefore be useful to know which antibiotic that attacks the bacteria. The purpose of this report is to analyze how antibiotics including Chloramphenicol and Ampicillin affect the growth rate of bacteria Escherichia coli and Bacillus subtilis. Which antibiotic is the most effective or least effective in inhibiting the growth rate of these two bacteria respectively? In the article Growth Chart (www.vetbact.org, 2015-11-19) it was written that bacteria are unicellular organisms that are in good nutrient availability can multiply indefinitely by dividing. It takes different amounts of time for different bacteria that doubled - this time called the generation time. When adding bacteria to a culture medium, it takes only a moment before they have adapted to their new environment. MicrobeWiki writes in his report Bacillus subtitles (microbewiki.kenyon.edu, 2016-05-10) that B. subtitles are gram-positive bacteria, facultative anaerobic bacteria which are classified as non-pathogenic. It occurs all over the place, for example in air, compost and soil, but can also be on the skin and in the human intestine, although it is not as common. Escherichia coli are gram negative, facultativeShow MoreRelatedLab Experiment: The Effectiveness of Different Antibiotics on Bacteria3118 Words   |  13 Pagesthe effect of different antibiotics on bacteria 2.

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 byRead MoreThe Use Of Probiotics1347 Words   |  6 Pages As a result of the various modes of action, the use of probiotics has improved growth rate in poultry. This improved performance could be due to the increased enzyme activity, increased villus height and surface area for absorption as well a reduction in stress put on the intestinal tract by pathogenic bacteria (Bajagai et al., 2016).

There has been a study that the mothanolic extract of the plant has anti microbial properties. The extract from Pansit- pansitan (Peperomia pellucida), the compound showed significant antibacterial activity against 3 Gram- negatice bacteria (E coli, Staphylococcus aureus, S thyphi.) The researchers expect that the hand soap, using Pansit- pansitan extract as an active ingredient, will be more efficient and less expensive than the commercial hand soaps.
