    Penicillin and Macrolides

    Penicillin and Macrolides, each having different properties belong to the same group of medicine called ANTIBIOTICs. Antibiotics refer to the chemical substance secreted or produced by various species of micro-organisms which are capable of inhibiting or killing the bacteria. Antibiotics have enabled the effective treatment of infections including life threatening diseases ranging from respiratory diseases to sexually transmitted diseases (Rang et al.,2007). An antibiotic acts by either limiting or stopping the growth of bacteria. It accomplishes this by probably interfering with the cell wall of the bacteria while having minimal effect on the normal body cells. Classifying bacteria into classes helps in identifying the bacterial species and hence they are classified as gram positive bacteria and gram negative bacteria based upon their staining techniques.…

    Genetic Engineering: Should We or Shouldn't We?

    Genetic engineering is a process in which scientists transfer genes from one species to another totally unrelated species. Usually this is done in order to get one organism to produce proteins, which it would not naturally produce. The genes taken from one species, which code for a particular protein, are put into cells of another species, using a vector. This can result in the cells producing the desired protein. It is used for producing proteins which can be used by humans, such as insulin for diabetics and is also used to make organisms better at surviving, for example genetically modifying a plant so that it can survive in acidic soil.…

    Genetic Engineering and a Brave New World

    A basic definition of the Genetic Engineering is it fact a little complex. In laymen terms Genetic Engineering involves the directed alteration of an organism's DNA (deoxyribonucleic acid) that is, its genetic material. This technology has been applied to microbes, plants, and animals, and consequently used to modify foods, animal feedstuffs, and food-processing reagents. (Peter Goldsbrough).…

    Horizontal Gene Transfer

    Horizontal Gene Transfer

    My research shows the rise in antibiotic resistant pathogens through horizontal gene transfer. Located in the bacteria are plasmids. They are independent, self-duplicating, and allow bacteria to perform new functions/generate new products. Basically plasmids help their hosts to stop the action of antibiotics and become resistant. “Gene transfer must be integral and critical to the overall survival of bacteria, providing a way for them to adapt to difficult conditions” (Levy 2002, 83). Horizontal gene transfer can occur through conjugation, transposition, transduction, and transformation. These forms of horizontal gene transfer have led to several ways for antibiotic resistant genes to be obtained. The acquiring of these resistant genes allow bacteria to stop the function of antibiotics.…

    Antibiotic Resistant Bacteria

    In the United States alone, about 23,000 people die from antibiotic resistant infections yearly. It is also one of the top 15 most dangerous illnesses in the country (United States House of Representatives). Antibiotic resistance is when bacteria develops a different response to an antibiotic that is its ancestor bacteria. Slight changes in bacteria enable the antibiotic to work and successfully cause an infection without a remedy. The misuse of antibiotics is the number one cause of bacteria resistance to antibiotics (United States House of Representatives). I will talk about how bacteria develop antibiotic resistance, how it affects doctors and patients, and how to prevent immunity to antibiotics.…

    Discovery of Antibiotics

    Antibiotics also known as antibacterial is a compound or substance that kills or slows down the growth of bacteria. The term antibiotic was coined by Selman Waksman in 1942 to describe any substance produced by a microorganism that is antagonistic to the growth of other microorganisms in high dilution. This definition excluded substances that kill bacteria, but are not produced by microorganisms. Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.…

    Genetic Modify Organism

    Today many scientist use “genetic engineering” a new technology that manipulates the genes of many plants, bacteria and animals. This organisms are called genetic modified organism (GMOs) because their genetic material (DNA) has been changed in a way that it doesn’t occur naturally, it alters the organism’s genetic material through adding, deleting or changing the segments in the DNA. This technology is also referred to as "biotechnology" or "recombinant DNA technology" because it randomly inserts genetic fragments of DNA from one organism to another, usually from different species to “improve” or get new traits that would be beneficial for humans.…

    Antibiotic Production

    The purpose of this experimental procedure is targeted to find a novel bacterium from the soil of Lantana camara that can be used in the dental field to kill or stop the growth of the Streptococcus mutans bacteria. The experimental procedure is to take place over a time frame of ten weeks conducted by a student team of four. The proposed methodology to take place is to cultivate and purify isolates from the soil, find antibiotic isolates, isolate the genomic DNA, to amplify the 16S rRNA gene segments by polymerase chain reaction, and to build a phylogenetic tree.…

    Ppt on Bt Brinjal

    Genetic modification involves the insertion or deletion of genes. In the process of Cisgenesis genes are artificially transferred between organisms that could be conventionally bred. In the process of Transgenesis genes from a different species are inserted, which is a form of horizontal gene transfer. In nature this can occur when exogenous DNA penetrates the cell membrane for any reason. To do this artificially may require attaching the genes to a virus or just physically inserting the extra DNA into the nucleus of the intended host with a very small syringe, or with very small particles fired from a gene gun.…
