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 ...
Currently, several hundred thousand deaths yearly can be attributed to infections with antibiotic-resistant bacteria. The major driver for the development of antibiotic resistance is considered to be the use, misuse and overuse of antibiotics in humans and animals. Nonantibiotic compounds, such as ...
Bacteria from their colons were carefully cultured, and many were already resistant to the most pow- erful modern antibiotics.4Evolutionists may speculate that such resistance fac- tors arose originally by step-by-step mutations, perhaps as they encountered similar chemicals in some past envi- ron...
42K Antibiotic resistance occurs when organisms like bacteria and fungi can withstand the drugs designed to counteract them. Discover the definition and types of antibiotic resistance, and then explore the antibiotic resistance strategies and problems they present. Related...
Step-by-Step Solution:1. Understanding the Question: The question asks where genes that represent traits of antibiotic resistance occur in bacteria. This requires knowledge of bacterial genetics and the stru
(ARGs) and fosters an increase in the relative abundance of resistant populations.8When these ARGs propagate to surrounding environments, antibiotic resistance becomes an environmental pollution problem, with ARGs as contaminants of emerging concern.9For example, when antibiotic-resistant bacteria (ARB) ...
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...
Dramatic increases in emerging resistance occurs and, when coupled with poor infection control practices, resistant bacteria can easily be disseminated to the other patients and the environment [2]. Availability of updated epidemiological data on antimicrobial resistance in frequently encountered bacterial ...
