Antimicrobial resistance (AMR) is a natural phenomenon in which microorganisms such as bacteria, viruses, fungi and parasites adapt to antimicrobial agents and cause medications to be ineffective for its curing purpose.... AMR is often the consequence of any use of antimicrobial drugs, exacerbated by inappropriate use.

Antimicrobial resistance happens when microorganisms (such as bacteria, fungi, viruses, and parasites) change when they are exposed to antimicrobial drugs (such as antibiotics, antifungals, antivirals, antimalarials, and anthelmintics). Microorganis...ms that develop antimicrobial resistance are sometimes referred to as “superbugs”.
As a result, the medicines become ineffective and infections persist in the body, increasing the risk of spread to others.

La résistance aux antimicrobiens Esurvient lorsque les micro-organismes (bactéries, champignons, virus et parasites) évoluent quand ils sont exposés à des médicaments antimicrobiens (comme les antibiotiques, les antifongiques, les antiviraux, ...les antipaludiques et les anthelminthiques).
On appelle parfois «super bactéries» celles qui développent une résistance aux antimicrobiens, mais cela concerne tous les micro-organismes.
En conséquence, les médicaments perdent leur efficacité et les infections persistent dans l’organisme, augmentant le risque de transmission à d’autres personnes.

Antimicrobial resistance (AMR) represents a major global threat across human, animal, plant food and environmental sectors, threatening the effective treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fung...i, resulting in prolonged illness and increased mortality, often felt hardest by the most vulnerable populations. AMR also endangers the sustainability of agri-food systems and food safety.
Since 2010 there is a strong commitment from FAO, OIE and PAHO to fight AMR, working together to mitigate the risks in the interconnection among the human health, animal health and the environment. In this context, the organizations now joined forces in the implementation of the project ‘Working Together to Fight Antimicrobial Resistance’ to ensure a coherent “One Health” approach recognizing the multidimensionality and necessity of an intersectoral response that is needed to address the problem of AMR.
The overall strategic objective of the three-year project (2020-22) supported and financed by the European Union (EU) is to contribute to tackle AMR through the implementation of National AMR Action Plans by working with seven Latin American partner countries: Argentina, Brazil, Chile, Colombia, Paraguay, Peru and Uruguay.

Antimicrobial resistance (AMR) is described as a situation when bacteria, viruses, fungi and parasites
change over time and no longer respond to medicines, making infections harder or impossible to treat,
and increasing the risk of disease spread,... severe illness and death.1 AMR in recent years has become
a global priority in public health due to its widespread consequences and increasing occurrence from
time to time. AMR has a formidable impact where the existing antibiotics and other antimicrobial
medicines become ineffective, and infections become increasingly difficult or impossible to treat.

Antimicrobial resistance (AMR) is one of the top 10 global public health threats facing humanity. AMR threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi.
It ...occurs when microorganisms develop resistance to medicines that are relied upon for treatment, making some conditions difficult or impossible to cure. As a result, infections persist in the body, increasing the risk of disease spread, severe illness and death.
The Antimicrobial Resistance channel offers learning resources to support implementation of the Global Action Plan on AMR (2015), by building health care worker competencies to help combat AMR in their daily clinical practice.

The Strategy to respond to antimalarial drug resistance in Africa is a technical and advocacy document, grounded in the best available evidence to date and aimed at minimizing the threat and impact of antimalarial drug resistance of Plasmodium falciparum p...arasites in Africa. Its objectives are to: i) improve the detection of resistance to ensure a timely response; ii) delay the emergence of resistance to artemisinin and artemisinin-based combination therapy (ACT) partner drugs; and iii) limit the selection and spread of resistant parasites where resistance has been confirmed.

Lymphatic filariasis, commonly known as elephantiasis, is a neglected tropical disease. Infection
occurs when filarial parasites are transmitted to humans through mosquitoes. When a mosquito
with infective stage larvae bites a person, the ...ass="attribute-to-highlight medbox">parasites are deposited on the person’s skin from
where they enter the body. The larvae then migrate to the lymphatic vessels where they develop
into adult worms in the human lymphatic system.

Dengue is a significant public health problem. There are four dengue virus serotypes identified; however, its diagnosis is difficult due to the existence of many viruses, bacteria, and parasites producing the same clinical presentation, being presen...t in the same geographical area and even producing coinfections. Therefore, determining whether a person has, had, or is infected with dengue virus is of great importance. In order to do so, direct and indirect laboratory tests have been developed to identify the virus or part of its structure that generally detects the antibody response. These techniques are used for diagnosis, epidemiological studies, monitoring, assessment and production of vaccines and antivirals, etc. They range from the use of cell cultures, animal models, inoculation by insects, and serology tests to the use of detection molecular tests and quantification of genetic material that are described in this chapter herein, a brief explanation of this methodology, its strengths and weaknesses, and its application in the dengue research.

Issue Brief 31: Antimicrobial resistance (AMR) can occur when viruses, bacteria, parasites and fungi change over time. There is no longer a response to medicines, and the infection treatment gets really difficult which increases the risk of a disesa...se spread, which can lead to severe health problems. AMR is an increasing threat to global public health worldwide that requires cross-sectional and cross-disciplinary action. It is present in every country and is spurred by several human-made factors, including over- and/or inadequate use of antibiotics, poor hygiene and infection prevention control, and excessive usage of antibiotics outside the health care sector e.g. in life stock production.

Lesson on schistosomiasis (bilharziasis): Causes, Symptoms and Treatment. Schistosomiasis is caused by parasitic blood flukes from the genus schistosoma. Schistosoma cercariae penetrate human skin and enter the bloodstream of the infected individual, where the ...box">parasites enter the portal vein. Schistosoma parasites also enter the mesenteric and bladder circulations, where they release eggs. Symptoms of schistosomiasis are related to the location of the parasites, the parasite burden and the amount of eggs produced. Systems affected in schistosomiasis include the hepatic, splenic, genitourinary, pulmonary, and nervous systems.

DNA studies of Egyptian mummies shows evidence of the existence of Schistosomiasis about 5000 years ago. Schistosomiasis is increasing in prevalence, affecting nearly 10% of the world’s population and ranking second only to malaria as a cause of morbidity & mortality.
Schistosoma haematobium are... found in tropical Africa & part of southwest Asia.
Schistosoma mansoni are found in tropical Africa, part of southwest Asia, south America & Caribbean islands.
Schistosoma japonicum are found in parts of Japan, China, Philippines, India & part of southeast Asia.
Blood flukes are known as schistosomes because of the "split body" on the ventral side of the male, in which the female is held during insemination and egg laying.
Man is the definite host harbouring adult parasites, and fresh water snails are intermediate hosts.

Schistosomiasis, also known as Bilharzia, is an infection caused by a parasitic worm that lives in fresh water in subtropical and tropical regions. Schistosomiasis is second only to malaria as the most devastating parasitic disease. The parasites th...at cause schistosomiasis live in certain types of freshwater snails. The infectious form, known as cercariae, emerge from the snail and then contaminate the water. People become infected when their skin comes into contact with the contaminated freshwater. Most human infections are caused by Schistosoma mansoni, Schistosoma haematobium, or Schistosoma japonicum.

There are 3 main forms of leishmaniases: visceral (the most serious form because it is almost always fatal without treatment), cutaneous (the most common, usually causing skin ulcers), and mucocutaneous (affecting mouth, nose and throat).
Leishmaniasis is caused by protozoan ...to-highlight medbox">parasites which are transmitted by the bite of infected female phlebotomine sandflies.
The disease affects some of the world’s poorest people and is associated with malnutrition, population displacement, poor housing, a weak immune system and lack of financial resources.
An estimated 700 000 to 1 million new cases occur annually.
Only a small fraction of those infected by parasites causing leishmaniasis will eventually develop the disease.

Leishmaniasis is a vector-borne disease with a broad global distribution and an increasing number of recorded cases worldwide. However, it is still one of the world's most neglected diseases. Over the last decades, the disease has been found to expand geographically with a global increase of cases o...f visceral and cutaneous leishmaniasis increasing the public health problems associated with the disease epidemics. The reported range expansion of the diseases has been associated with range expansions of vector populations in response to climate change. Leishmaniasis is caused by protozoan parasites of the genus Leishmania. The transmission can either be zoonotic and/or anthroponotic through the bite of an infected female phlebotomine sandfly. In Eurasia and Africa, all vector-competent sandfly species belong to the genus Phlebotomus. Cutaneous leishmaniasis (CL) is the most common form of leishmaniasis. In the ‘old world’, it is caused by five currently recognized Leishmania species: L. major, L. tropica and L. aethiopica (being main causative parasites) as well as L. infantum and L. donovani. Visceral leishmaniasis (VL), another common and more severe form of leishmaniasis, is only associated with the Leishmania species L. infantum and L. donovani. The specific Leishmania species cause different clinical symptoms in humans.
