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

Vu Nguyen BIOL 1003/22 ANTIBIOTIC RESISTANCE LAB REPORT Introduction Natural selection is a non-random process in which individual with favorable traits for the environment will likely survive and reproduce than those without these traits. In contrast to Natural selection‚ Artificial selection is the process in which desired traits are intentionally chose to breed among individuals. Antibacterial resistance is the process in which strong and highly resistant bacterial is selected against weaker bacterial

Mechanisms of Silver Nanoparticle Action in Bacteria and Potential for Bacterial Resistance The antimicrobial activity of silver in general‚ and of silver nanoparticles in particular‚ is of significant interest because it appears to be independent of the strain of bacteria. Crucially‚ antibiotic resistant strains‚ MRSA (methicillin‚ or multiple-resistant Staphylococcus aureus)‚ E. coli O157‚ and others are affected by silver [6]. The reasons for this are not fully clear as yet‚ but could be related

Antimicrobial Resistance: Public Health Issue and Role of Nurses in Prevention Antimicrobial resistance is a significant global issue with serious implications for human health. The microorganisms that were previously sensitive to antibiotic treatment are now capable of withstanding attacks by antimicrobial medicines. One of the main reasons that cause antimicrobial resistance is the misuse of antibiotics‚ which includes an inappropriate selection of antibiotic type‚ dose‚ route‚ or duration of

The Rise of Antibiotic-Resistant Infections by_ Ricki Lewis‚ Ph.D._ When penicillin became widely available during the second world war‚ it was a medical miracle‚ rapidly vanquishing the biggest wartime killer--infected wounds. Discovered initially by a French medical student‚ Ernest Duchesne‚ in 1896‚ and then rediscovered by Scottish physician Alexander Fleming in 1928‚ the product of the soil mold Penicillium crippled many types of disease-causing bacteria. But just four years after drug

When the Antibiotics Quit Working It seems as though antibiotics are slowly losing the battle against infectious disease thus causing a greater demand for researchers to invent new antibiotics that have new mechanisms for killing microbes as well as new vaccines. The problem is that bacteria are becoming resistant to antibiotics. When bacteria are exposed to antibiotics they are under “selective pressure” that allows

well as other animals‚ have you ever thought about the times when all of those animals eat. The feed that they eat very often contains different types of antibiotics. These antibiotics have many raising concerns for health factors when passed through the live stock when those animals are processed for us to consume. I believe that those antibiotics and drugs that are passed through the feed have an adverse effect on the meat when it is processed. There are many articles that have been published stating

This report by Wright‚ Seiple‚ and Meyers discusses mainly the history of antibiotics as well as its link to future discoveries. Each section in the report examines different points throughout the essay: 1) The authors suggest chemical synthesis as the key to the development of the first antibiotic. All antibiotics discovered by humans have been categorised into one of the following: natural products (manufactured directly by bacteria)‚ semisynthetic antibacterials (manufactured by chemical synthesis

Antibiotics An antibiotic is defined as a substance that is produced by microorganisms that in miniscule amounts inhibits the growth of another microorganism (Tortora 2010). Antibiotics can be found naturally in the environment or they can be manufactured with chemicals. They are specifically designed to hinder the growth and development in other microbes. Yet‚ these antimicrobial drugs should not cause extreme harm to normal microorganisms (Tortora 2010). The vast majority of antibiotics
