Introduction Antibiotics are drugs that have been developed to destroy or show interference with the growth of microorganisms. The first antibiotic properties revealed were synthetic chemicals‚ particularly drugs containing arsenic‚ which were discovered by Ehrlich at the beginning of the 20th century. Sulphonamide inhibitors of folate metabolism were developed by Domagz in the 1930s which then followed with the development of the first true antibiotic‚ penicillin in the 1940s.(Wright 2011) Upon

The 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 more

possible actions that can be brought to the antibiotic resistance issue. My name is Dr. Joe. I am a professor of professor of Society and Genetics. Through the research facilities at the university‚ I cultivate bacteria and observe what harms or benefits the different species are. For years‚ I focused my research on society’s effect on bacteria’s natural development. The issue I bring to you today demands a shift in perception of bacteria and antibiotics‚ a paradigm shift. We need to change the way

Lab Report: Antibiotic Evaluation by the Kirby-Bauer Method Introduction Chemical antimicrobial agents are chemical compounds capable of either inhibiting the growth of microorganisms or killing them outright. 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 by

Antibiotics M. Camila Alvarez As described by doctors‚ antibiotics are powerful medicines that fight bacterial infections. Bacteria are widely spread throughout the globe and if used properly‚ can save lives. They either kill bacteria or keep them from reproducing. From there‚ this issue can be taken by your body’s natural defenses. Although these chemicals may seem very productive at times‚ they do more harm than good. Each time your body receives antibiotics; it increases the chances that bacteria

Sampling of Gram-Positive Bacteria and Antibiotic Resistance Resting We thought it would be interesting to find out the different bacteria that grow on things we use on a daily basis and the level of antibiotic resistance that those bacteria have. We chose to swab the toilet seat in the MATC women’s bathroom and the ATM machine in the commons area on campus. We were certain the ATM would be dirtier than the toilet seat since the bathrooms get cleaned every day. The first step we took in testing

Treatment of Antibiotic Pharmaceutical Wastewater Using a Rotating Biological Contactor One of the treatment of the wastewater is the treatment of antibiotic pharmaceutical wastewater using a rotating biological contactor. For your information‚ Rotating Biological Contactors (RBC) are effective for treating wastewater‚ while they are rarely reported to be used for treating antibiotic pharmaceutical wastewater (APW). Next‚ the biological treatment processes have been widely used in wastewater treatment
