The controversy regarding the sub-therapeutic use of antibiotics in animal feeds is that “super-bugs” are able to evolve. This is a threat to both the health of the animals and humans. What a “super-bug” refers to is a strain of bacteria that has evolved to be resistant to bacteria and lethal to the host organism. These super-bugs account for the death of roughly 48,000 Americans each year (Adams, 2013). These superbugs proliferate in the digestive tracts of hosts. Each dose of antibiotics in
Introduction: Antibiotics have the ability to kill or hinder the growth of bacteria. Antibiotics contain compounds that are naturally produced by organisms to combat diseases caused by microbes. Discovery of penicillin by Sir Alexander Fleming became the first stepping stone of many new antibiotics of today’s modern medicine. Antibiotics typically invade the very components that make up bacteria, such as cell walls and metabolic pathways (Sato et al., 2014). However, frequent mutations of bacteria
2007). Aminoglycosides and tetracyclines affect the ribosomes of bacterial cells; aminoglycosides block the initiation phase of translation during protein synthesis, which causes a misreading of mRNA, and tetracycline blocks the attachment of tRNA to the ribosome of the bacterial cell (Nester, 2007). Aminoglycosides also have a low therapeutic index, meaning it can be harmful to humans (Nester, 2007). Streptomycin is often used for treating tuberculosis and tetracycline is used for a variety of bacterial
Describe the mode of action of the tetracyclines. What are the pros and cons of prescribing tetracycline? Tetracyclines act by binding to ribosomes and blocking protein synthesis. They are broad-spectrum drugs that can act on gram-positive and gram-negative rods and cocci, aerobic and anaerobic bacteria, mycoplasmas, rickettsiae and spirochetes. Tetracyclines are administered orally and is cheap and easy to administer, but come with side effects
Ampicillin Ampicillin disrupts the third and final stage of bacterial cell wall synthesis by binding specific penicillin-binding proteins (PBPs) that are inside the bacterial cell wall. Then facilitated by bacterial cell wall autolytic enzymes, cell lysis beings. Ampicillin is metabolized by Hydrolysis of the B-lactam ring to penicilloic acid. Microorganisms such as salmonella, Escherichia coli, campylobacter, shigella aquificae, thermotogae, chrysiogenetes, nitrospira, deferribacteres, other eubacteria
Penicillins have been considered as first-line drug for odontogenic infections. Amoxycillin, a semi synthetic penicillin is the drug of choice in treating dental infections and is the most common antibiotic used by dentists . If a patient with an early stage odontogenic infection does not respond to Amoxycillin , there is a strong probability of the presence of resistant bacteria. Bacterial resistance to the penicillins is a result of the production of beta-lactamase by the bacteria. therefore
what they do! They include: Cephalexin, Cephradine, Cefadroxil, Cefaclor, Cefazolin, and Cephalothin. 9. Tetracyclines usually act as time-dependent antibiotics and inhibit protein synthesis by reversing ribosomes, inhibiting protein creation by preventing bindings of transfer-RNA. They include: Chlortetracycline, Tetracycline, Doxycycline, and Oxytetracycline. A major side effect of Tetracyclines are tooth degeneration in newborns and young
then is observed after 24 hours to determine the effectiveness of different types of antibiotics. The main result of this experiment is that the paper dics soaked with tetracycline has the greatest zone of inhibition in both Bacillus subtilis and E. Coli agar plates. Therefore, from this experiment, we can conclude that Tetracycline is the most effective antibiotics for Bacillus subtilis and E. Coli. Introduction: Antibiotics Antibiotics are among the frequently prescribed medicine for treating
Penicillin, and Erythromycin, and sensitive or intermediate to others. With Penicillin and Bacitracin no zone of inhibition was identified which is a very accurate result. Then Pseudo aeruginosa which is resistant to Penicillin but very sensitive to Tetracycline since we saw a inhibition zone of 26mm. Our results were pretty close to class average and turned out accurate except for some. Especially in case of Strep faecalis, where it should have been sensitive to Erythromycin it only covered 6mm. It is
A.1. Statement of problem: Acinetobacter baumannii (A. baumannii) is a nosocomial, gram-negative bacterium commonly associated with pneumonia, meningitis, bacteremia, wound and urinary tract infections [1,2,25]. These bacteria are capable of preventing desiccation allowing it to thrive before prolong periods on various wet or dry surfaces. As an opportunistic human pathogen, A. baumannii may colonize a patient without causing any infections or symptoms, especially in tracheostomy sites or open
As the dentist and his assistant worked diligently to complete the cavitation surgery, I felt a very odd sensation in my neck; it was very subtle. The dense feeling and discomfort I had felt for many years was completely gone. It dawned on me that the lymph in my neck had released! The lumpiness and accompanying achiness were gone! My husband was right; my lymph had been doing its job all along — to protect the body from what was in the wisdom tooth socket. Now with the cavitations cleaned out there
antibiotics due to containing penicillin-binding proteins. That means they are still able to combine cell wall components. There can be acquired resistance of Enterococci that comprises of resistance to penicillin by beta-lactamases, chloramphenicol, tetracyclines, rifampin, fluoroquinolones, aminoglycosides, and vancomycin. There is a potential for cell-wall synthesis because the genes that encrypt intrinsic or acquired vancomycin resistance produce in a peptide to which vancomycin cannot connect. Unfortunately
Bad Breath and Teeth Staining Halitosis is the medical term for Bad Breath. When people think of bad breath they automatically think that food is the cause of the bad odor. When in reality there are many factors that can lead up to bad breath. Yes food is one of them but there are other reasons as to why a person may be experiencing bad breath or teeth staining. A person may experience bad breath or teeth staining because they may have a health problem that is causing the odor other factors are
Antibiotics have played a major role in our society thanks to Sir Alexander Fleming's careful observations in 1928. Without it, many lives would be in danger due to infectious diseases. Antibiotics are chemical substances produced by various species of microorganisms and other living systems that are capable in small concentrations of inhibiting the growth of or killing bacteria and other microorganisms. These organisms can be bacteria, viruses, fungi, or animals called protozoa. A particular
Phar 6724 Introduction to the Immune System and Infectious Disease Emerging Infectious Disease Assignment Spring Semester 2016 Over the last three decades, a significant number of new pathogens have been identified that have been responsible for localized epidemics and outbreaks. Some of these diseases have been widely publicized e.g. West Nile Virus & SARS Coronavirus, Zika virus, Ebola virus etc. One of the functions of the Centers for Disease Control is to conduct research and gather information
Many people, including children and most especially the elderly, are taking more than one drug or supplement on a daily basis. Healthy individuals sometimes take different over-the-counter diet supplements, herbal products, energy drinks containing various chemicals, birth control pills, pain medications as needed, topical creams and ointments, and others. Patients with chronic conditions often receive prescriptions for various drugs, including supplements to boost health, and more. Most of us are
Organism Naegleria fowleri, the brain eating amoeba, exists around the world; reservoirs of N fowleri include sediments of lakes, rivers, geothermal water, soil, and poorly kept swimming pools. These microbes can live in temperatures up to 45 degree Celsius and do not require a host cell for survival. The free-living amoeba is the etiological source of primary amoebic meningeocephalitis (PAM), an acute and fatal disease of the central nervous system with fatality rates over 99%. Onset of illness
