INTRODUCTION. The rapid emergence of resistant bacteria is occurring worldwide, endangering the efficacy of antibiotics, which have transformed medicine and saved millions of lives. 1–6 Many decades after the first patients were treated with antibiotics, bacterial infections have again become a threat.
What options do we have in combating antibiotic resistance?
To prevent and control the spread of antibiotic resistance, health professionals can:Prevent infections by ensuring your hands, instruments, and environment are clean.Only prescribe and dispense antibiotics when they are needed, according to current guidelines.More items...•
What causes widespread antibiotic resistance?
Misuse and overuse of antimicrobials are the main drivers in the development of drug-resistant pathogens. Lack of clean water and sanitation and inadequate infection prevention and control promotes the spread of microbes, some of which can be resistant to antimicrobial treatment.
What are the types of drug resistance?
Antimicrobial resistance mechanisms fall into four main categories: (1) limiting uptake of a drug; (2) modifying a drug target; (3) inactivating a drug; (4) active drug efflux.
What is the largest contributing factor in the USA to antibiotic resistance?
In the United States and other developed countries, one leading factor is the over-prescription by physicians of antimicrobials, particularly antibiotics, even in the absence of appropriate indications.
How can we slow down the spread of antibiotic resistance?
Infection-prevention activities have been proven to be effective in slowing the spread of resistant germs. These include vaccination, implementing hand hygiene and responding rapidly to unusual genes and germs when they first appear.
What is antibiotic resistance and how does it occur quizlet?
What is Antibiotic Resistance? -Ability of bacteria or other microbes to resist the effects of an antibiotic. -Natural selection gives resistant organisms an adaptive advantage.
What is resistance in medicine?
Resistance: Opposition to something, or the ability to withstand something. For example, some forms of the staphylococcus bacterium are resistant to treatment with antibiotics.

What is involved in the spread of resistance?
Poor hygiene, poor sanitation, and poor infection control are three interconnected key factors contributing to the spread of resistant bacteria in health care facilities, in farms and in the community.
What causes drug resistance?
Microbes also may get genes from each other, including genes that make the microbe drug resistant. Bacteria multiply by the billions. Bacteria that have drug-resistant DNA may transfer a copy of these genes to other bacteria. Non-resistant bacteria receive the new DNA and become resistant to drugs.
How does resistance to drugs spread in bacterial populations?
How does antibiotic resistance spread? Genetically, antibiotic resistance spreads through bacteria populations both "vertically," when new generations inherit antibiotic resistance genes, and "horizontally," when bacteria share or exchange sections of genetic material with other bacteria.

The National Strategy: A Roadmap for Combating Antibiotic Resistance. In 2013 CDC released Antibiotic Resistance Threats in the United States, 2013, the first report to look at the burden and threats posed by antibiotic resistance on human health. This report named antibiotic-resistant gonorrhea among the three most urgent threats ...
What is DSTDP in gonorrhea?
In large part, DSTDP makes decisions about national treatment recommendations using data from the Gonococcal Isolate Surveillance Project (GISP). Gonorrhea specimens from men with symptoms of urethritis in 26 STD clinics in selected U.S. cities are collected each month for culture and sent to their local laboratory for isolation of the bacteria. Regional laboratories in the AR Lab Network then test these isolates for resistance to the different antibiotics that are, or were, used to treat gonorrhea. All clinical, epidemiologic, and laboratory results are then sent to CDC and used to determine the most effective treatment to recommend for gonorrhea, based on nationwide susceptibility and resistance patterns and trends.
Does DSTDP treat gonorrhea?
Gonorrhea control in the U.S. relies on our ability to detect and treat each case of gonorrhea quickly and effectively with the right antibiotic; because of this, DSTDP is taking a multipronged, capacity-building approach to tackle the problem.

What is the global action plan for AMR?
Globally, countries committed to the framework set out in the Global Action Plan 1 (GAP) 2015 on AMR during the 2015 World Health Assembly and committed to the development and implementation of multisectoral national action plans. It was subsequently endorsed by the Governing Bodies of the Food and Agriculture Organization of the United Nations (FAO) and the World Organisation for Animal Health (OIE). To ensure global progress, countries need to ensure costing and implementation of national action plans across sectors to ensure sustainable progress. Prior to the endorsement of the GAP in 2015, global efforts to contain AMR included the WHO global strategy for containment of Antimicrobial Resistance developed in 2001 which provides a framework of interventions to slow the emergence and reduce the spread of AMR.
What is the purpose of World Antibiotic Awareness Week?
This will reflect the broadened scope of WAAW to include all antimicrobials including antibiotics, antifungals, antiparasitics and antivirals. Held annually since 2015, WAAW is a global campaign that aims to raise awareness of antimicrobial resistance worldwide and encourage best practices among the general public , health workers and policy makers to slow the development and spread of drug-resistant infections. The Tripartite Executive Committee decided to set all future WAAW dates as 18 to 24 November, starting with WAAW 2020. The overarching slogan used for the last 5 years was “Antibiotics: Handle with Care.” This has been changed to “Antimicrobials: Handle with Care” in 2020.

The political declaration at the UN High Level Meeting on AMR, committed to by Heads of State at the United Nations General Assembly in New York in September 2016, confirmed a strong focus on a broad, coordinated approach that engages all including the human, animal, plant and environmental health sectors. WHO is working closely with FAO and OIE in a ‘One Health’ approach to promote best practices to reduce the levels of AMR and slow its development.
What is the best treatment for P. falciparum?
The emergence of drug-resistant parasites poses one of the greatest threats to malaria control and results in increased malaria morbidity and mortality. Artemisinin-based combination therapies (ACTs) are the recommended first-line treatment for uncomplicated P. falciparum malaria and are used by most malaria endemic countries. ACTs are a combination of an artemisinin component and a partner drug. In the WHO Western Pacific Region and in the WHO South-East Asia Region, partial resistance to artemisinin and resistance to a number of the ACT partner drugs has been confirmed in Cambodia, Lao People’s Democratic Republic, Myanmar, Thailand, and Viet Nam through studies conducted between 2001 and 2019. This makes selecting the right treatment more challenging and requires close monitoring.
