ANTIBIOTICS 1. For each of the following antibiotics name the microorganism responsible for their production, using the appropriate naming convention. a) Penicillin: Penicillium chrysogenum/P.notatum b) Erythromycin: Saccharopolyspora erythraea c) Vancomycin : Amycolaptosis orientali 2. Explain why antibiotics are produced by microorganisms. Antibiotics are produced by microorganism because they inhibit the growth of or kill other microorganisms; they are effective in low concentrations and act on specific species of microorganisms.
Vancomycin-Resistant Enterococcus - Enterococci bacteria are normally found in the intestinal tract. They can sometimes become pathogenic and develop resistance to vancomycin. Vancomycin is considered to be the last-resort antibiotic that is administered for infections that are resistant to penicillin and other antibiotics. Vancomycin-resistance decreased because the antibiotic was no longer used and the resistant strains were no longer selected for. With recent outbreaks of MRSA (Methicillin-resistant Staphylococcus aureus) VRE demonstrates that decreasing use of antibiotics can decrease the drug resistance in bacterial
Around 781.000 people die of malaria each year. So precautions must be took in order to avoid catching it. TASK 4 (D1) The affect of how antibiotics work in order to fight and kill the harmful Bacteria. Introduction; The aim of our experiment was to find out how and which antibiotics and antimicrobials work on best in fighting specific Bacteria. These being, E.Coli and S.Albus.

Improper use of antibiotics is the primary cause of drug-resistant bacteria. When a person begins to take their medication the weaker strains of the bacteria are killed off first leaving the more resistant bacteria behind. Unfortunately when a person does not finish their prescription the more resistant bacteria continues to live and multiply, resulting in the ineffectiveness of antibiotics, and failure to control the
Rats deficient in vitamin A had little chance of survival when inoculated with whopping cough germs, while those receiving adequate amounts of the vitamin, found in cod liver oil, recovered from the disease. In the late 1940s, streptomycin and aureomycin became the cures of choice. Streptomycin was first reported to be effective against whooping cough in Buffalo. Doctors even reported that if the treatment was given to the child before they began to whoop, roughly ten days after the beginning of the disease, the disease could be controlled. Aureomycin was discovered to be successful in defeating the disease once the disease was resistant to streptomycin.
The discovery of penicillin became a widely used medicine in the year of 1943 the required clinical trials were performed showing an effective and fastest way to treat medical wounds. though it is peculiar that one stray mold spore could have been responsible for the discovery of penicillin. so what made penicillin a special medical use? penicillin was originally discovered by French medical student named Ernest Duchesne in 1896.penicillin was then re-discovered by bacteriologist Alexander Fleming. he observed that a plate culture that contained staphylococcus had been contaminated by a blue green mold and that colonies of bacteria adjacent to the mold were being dissolved.curiously Alexander grew the mold in a pure culture and found that it produced a substance that killed a number of disease causing bacteria.
Moreover it will also provide a brief discussion on the treatment and preventive aspects of MRSA. MRSA or Methicillin-Resistant Staphylococcus Aureus Infections Introduction Methicillin-resistant Staphylococcus aureus is an infection that is hard to cure. Doctors and nurses sometimes call it MRSA or "Mursa" for short (Boyce, 2009). People normally carry all sorts of germs inside their body and on their skin. The body usually controls these germs, so they do no harm.
A European physician, Professor A Weichselbaum, discovered the cause of the mysterious cerebro-spinal meningitis illness in 1887 and Penicillin was the first antibiotic used to fight the disease. In 1978 the first vaccine was created and mass vaccinations during that year caused a substantial decline in the number of meningitis outbreaks (Fredericks, n.d.). There are three main types of meningococcal disease serogroups: B, C, and Y. Worldwide there are also A and W-135. USA vaccines cover A, C, W-135, and Y but not B (Coffee, 2015).
It has been noticed that the same drugs that suppress the immune system so that lupus can't attack the body also reduce a person's ability to fight off bacterial and viral infections. “If a person has more severe manifestations of the lupus that brought them to the hospital their symptoms are going to be treated with aggressive immunosuppressant’s, and that's going to increase their risk of infection," said Dr. Joan Merrill, medical director of the Lupus Foundation of America. It was also stated that more than likely, it’s going to increase their risk of re-hospitalization, and the treatments don't work, then they’re at risk of organ
