Antibiotic resistance

Isolated in the 1950s from a Stretopmyces orientalist strain found in a Borneo jungle and clinically introduced in 1958, the antibiotic has a spectrum of activity limited to gram-positive organisms: it is too large to cross gram-negative bacterial membranes, and thus has no impact on these organisms. Vancomycin works against gram-positive bacteria by inhibiting peptidoglycan synthesis…

zones of inhibition when exposed to the three antibiotics. Gram-staining confirmed the identity of S. epidermidis as a gram-positive bacteria and S. enteritidis as a gram-negative bacteria.…

diagnosis is time consuming.this matter necessitates the initiation of empirical antibiotic therapy till the suspected sepsis is ruled out. At the same time ,increased multidrug resistant organisms make the treatment options fewer and the effective treatment is delayed(patel sj and saiman l 2010) Along with other organisms like klebsiella…

bone regeneration avoiding multiple surgeries and delaying reconstruction. While local use of antibiotics is currently the most common treatment for bone graft infections, the extensive use of antibiotics worldwide during the last decades has led to antimicrobial resistance…

Officer believes that antibiotic resistance should be ranked with terrorism as “one of the major threats to society” (Cribb, 2013, p. 47). The World Health Organisation (WHO) has taken these unnerving words into consideration as a potential threat towards society and, as a result, made this issue the main focus of World Health Day 2011. The World Health Organisation warned global citizens that “inaction today will lead to many deaths in the future” (Cribb, 2013, p. 47). Antibiotics that are…

Brandy Lauder broke a toe and had to get orthopedic surgery to get it repaired. She was then prescribed antibiotics for ten days. The antibiotics depleted the bacteria that kept Clostridium difficile under control, which caused her to get a debilitating infection. She first got diarrhea and then went into shock. Her intestines swelled up and she had to get surgery to give room to her swollen and blood-deprived organs. The bacterium that caused her infection was Clostridium difficile. The…

become better adapted and more suited to their environment. This increases their chances of survival, and thus they are able to produce more offspring who are also equipped with these advantageous adaptations. One example of this process is antibiotic resistance. Evolution is a process that can contribute to the understanding of many phenomena, especially in the field of biomedical science. The significance…

Are Antibiotics Killing Us? Although antibiotics have made modern medicine a possibility, antibiotic-resistant bacteria will cause an apocalypse because of over prescribing to patients and distribution of too many antibiotics to livestock. The Center for Disease Control and Prevention (2016) defines antibiotic-resistant bacteria by saying that, “Antibiotic resistance occurs when bacteria change in a way that reduces the effectiveness of drugs, chemicals, or other agents designed to cure or…

Methicillin was first developed in 1959 as an antibiotic against penicillin-resistant Staphylococcus aureus. This beta-lactam antibiotic inhibits the synthesis of bacterial cell walls and inhibits cross-linkage between the linear peptidoglycan polymer chains, essentials for the cell wall of Gram-positive bacteria. This antibiotic is a derivative and modification to the original beta-lactam antibiotic penicillin and is penicillinase-resistant, which is effective against S. aureus bacterium’s…

coli JM101, followed by oil of oregano and apple cider vinegar having some effect. Similar results were found in a science fair project conducted by Charles Boyd where they concluded that antibiotics and some natural remedies were effective at inhibiting the growth of bacteria. However, the results were qualitative with little description of the zone of inhibition (Boyd, 2008). There may be a difference in the effectiveness of these treatments…
