ANTIBIOTIC RESISTANCE OCCURS WHEN bacteria evolve under selection pressure from antibiotic use and become resistant to the medication. Because a generation for a bacterium is extremely short (no more than one day, and often less than an hour), such evolution can occur very quickly. The result is...
Antimicrobial resistance can be categorized as either intrinsic or acquired. Intrinsic resistance occurs when bacteria are non-responsive to an antibiotic despite lack of prior exposure to the antibiotic. This occurs in microorganisms as part of their natural structural or functional characteristics. For ...
The development of antibiotic resistance in bacteria is an example of___. A. natural selection B. artificial selection C. genetic mutation D. random variation 相关知识点: 试题来源: 解析 A。细菌对抗生素的耐药性发展是自然选择的一个例子。具有耐药性的细菌在抗生素环境中更有可能存活和繁殖,从而使耐...
Antibiotic resistance, loss of susceptibility of bacteria to the killing (bacteriocidal) or growth-inhibiting (bacteriostatic) properties of an antibiotic agent. When a resistant strain of bacteria is the dominant strain in an infection, the infection ma
Other infection types can include ear and sinus infections, meningitis, and bloodstream infections. Drug-resistance to Streptococcus pneumoniae depends upon the area in which you live. When these bacteria are resistant to penicillin, they are often resistant to many other antibiotic classes. Resistance...
resistance can emerge through the transfer of resistance genes on plasmids, through transduction, or natural transformation. Resistance genes are often found in mobilegeneticelements, such astransposonsandintegronsthat can enhance their spread. Traditional methods to genotype bacteria such as PCR-based appr...
Antibiotic resistant bacteriaare strains of bacteria that do not respond to antibiotics. Instances of antibiotic resistance bacteria may occur on an individual basis or on a much larger scale. We'll touch on both. Imagine that you are sick and your doctor has confirmed that bacteria are to blam...
Reference data on the overall resistance patterns of anaerobic bacteria are needed since in individual clinical cases susceptibility testing is complicated... W Niederau - 《Infection》 被引量: 29发表: 1982年 Antibiotic Resistance: Can Nanoparticles Tackle the Problem? - ScienceDirect The gradual incre...
Antibiotic resistance A problem that has plagued antibiotictherapyfrom the earliest days is the resistance thatbacteriacan develop to thedrugs. An antibiotic may kill virtually all the bacteria causing a disease in a patient, but a few bacteria that are genetically lessvulnerableto the effects of th...
The main consequences of use and abuse of antibiotics is the development and diffusion of antibiotic resistance that has become a serious global problem. Aim of the study is to evaluate the presence of antimicrobial residues and to assess the antimicrobial resistance in bacteria species isolated from...
