	ß-Lactams: Mechanisms of Action and Resistance  Developed and produced by www.MechanismsinMedicine.com Animation Description This animation starts with the explanation of bacterial cell wall synthesis, the process targeted by ß-Lactams. Structurally, most bacteria consist of a cell membrane surrounded by a cell wall and, for some bacteria, an additional outer layer. Internal to the cell membrane is the cytoplasm which contains ribosomes, a nuclear region and in some cases granules and/or vesicles. Depending on the bacterial species, a number of different external structures may be found such as a capsule, flagella and pili. In gram negative bacteria, the gap between the cell membrane and the cell wall is known as the periplasmic space. Most gram positive bacteria do not possess a periplasmic space but have only periplasm where metabolic digestion occurs and new cell peptidoglycan is attached. Peptidoglycan, the most important component of the cell wall, is a polymer made of N-acetyl muramic acid alternating with N-acetyl glucosamine which are cross-linked by chains of four amino acids. The function of the bacterial cell wall is to maintain the characteristic shape of the organism and to prevent the bacterium from bursting when fluid flows into the organism by osmosis. Synthesis of peptidoglycan and ultimately the bacterial cell wall occurs in a number of stages. One of the first stages is the addition of 5 amino acids to N-acetyl muramic acid. Next, N-acetyl glucosamine is added to the N-acetyl muramic acid to form a ... 2011年03月30日再生回数 51613

	antibiotics first 15 min.mov  Antibiotics for HENT - As a side note, I did not express the fact that Beta Lactam antibiotics also have a secondary effect by increasing the activity of bacterial autolysin enzymes that are used to recycle their cell wall. Because of this action, beta lactam drugs cause the bacteria to eat up their own wall at an accelerated rate, resulting in bacterial cell death. 2011年09月19日再生回数 202
	ARI: Antibiotic Resistance Investigation-MRSA  This video was created for Microbial Physiology MIP 443 Extra Credit at Colorado State University. We delve into the workings of MRSA. An undercover antibiotic (Methicillin, orange shirt) is found murdered with a mec A gene gun at the crime scene. The Coroner tell us how peptidoglycan synthesis normally occurs and why our Beta-lactam didn't protect the cop. Ballistics tells us how Beta-lactam antibiotics are supposed to work (methicillin is drawn on the board) and why with MRSA, with the mec A gene from the gene gun, Beta-lactams are ineffective at inhibiting peptidoglycan synthesis. An interview of the pathogenicity island SccMec where the mec A gene is traced back to occurs. We encounter his daughter (Stapholococcus auerus) who has recently joined MRSA....

	Deadly NDM-1 superbug has reached Malaysia  The Indian Superbug NDM-1 that has killed at least 21 people all over the world has reached our shores. The New Delhi metallo-beta-lactamase (NDM-1) is an enzyme that that renders certain antibiotics, especially the carbapenem variants useless. Carbapenem antibiotics are often used to treat resistant bacteria strains. For full story, please visit www.klik4malaysia.com 2010年10月27日再生回数 501
	Indian docs cautious over new superbug, rule out major impact  Gurgaon, August 13 (ANI): Indian doctors said on Thursday that it was hard to prove that the new superbug - a gene called New Delhi metallo-beta-lactamase, or NDM-1, found in patients in South Asia and Britain could be attributed to medical tourism from the country alone while pressing for stringent antibiotic policies. But Dr Katariya added it was hard to gauge the impact of the findings on overseas patients coming to India for specialized treatment. Researchers had said on Wednesday the new superbug from India could spread around the world, in part because of medical tourism, with scientists saying there are almost no drugs to treat it. 2010年08月14日再生回数 1673
