Human scabies is a parasitic infestation caused by Sarcoptes scabiei var hominis. The microscopic mite burrows into the skin and lays eggs, eventually triggering a host immune response that leads to intense itching and rash. Scabies infestation may be complicated by bacterial infection, leading to t...he development of skin sores that, in turn, may lead to the development of more serious consequences such as septicaemia, heart disease and chronic kidney disease. In 2017, scabies and other ectoparasites were included as Neglected Tropical Diseases (NTDs), in response to requests from Member States and the recommendations of the WHO Strategic and Technical Advisory Group for NTDs.

Buruli ulcer is a chronic, progressive skin disease caused by infection with Mycobacterium ulcerans. It is currently considered to be one of the neglected tropical diseases; less common than tuberculosis but more common than leprosy. The initial lesion is a painless subcutaneous nodule, usually less... than 5 cm diameter and adherent to skin. The nodule typically breaks down centrally after days to weeks forming an ulcer with undermined edges. Thus, the external appearance of the ulcer underestimates the true size of the affected area. The patient remains well and there is no pain unless secondary bacterial infection occurs. Other forms of M. ulcerans disease include a firm plaque lesions that behaves in the same way as the nodule or an oedematous lesion that is more aggressive and extends rapidly resulting in a very large ulcer.
Any age group can be affected by Buruli ulcer diseases, but the incidence peaks at 5 to 15 years. Ulcers are most frequently on the limbs but can be on the trunk or head, sometimes with catastrophic consequences such as loss of sight or loss of breast or genital tissue. Healing close to a joint can result in contracture, and sometimes there is so much tissue destruction on a limb that amputation is unavoidable. Occasionally osteomyelitis occurs in bone adjacent to a skin lesion but involvement of other organs is rare. Disseminated disease with HIV has been reported.

This study was an exploratory situation analysis assessing public and private service providers knowledge, attitudes and practice to treat possible severe bacterial infection (PSBI) among children less than six months of age.
Antimicrobial agents like antibiotics are essential to treat some human and animal diseases. Microbes, such as bacteria, can develop resistance to antimicrobials meaning that a drug such as an antibiotic is no longer effective in treating the infection. The development of resistance is caused by the... incorrect use of these drugs, for example, using antibiotics (which help to treat bacteria) for viral infections like flu, or as a growth promoter in agriculture.

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 me...dicines 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.

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 fungi, resulting in prolonged illness and increased mor...tality, 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.

Mycetoma is a chronic disease usually of the foot but any part of the body can be affected. Infection is most probably acquired by traumatic inoculation of fungi or bacteria into the subcutaneous tissue. So far more than 70 different bacteria and fungi have been indicated as causative agents.
Antimicrobials are used in veterinary medicine to treat infectious diseases in animals caused or complicated by microorganisms, mainly bacteria, or to prevent the development or spread of infection in healthy animals.
Policy Brief November 2021 Available in English, Spanish and Portuguese
The COVID-19 pandemic has fueled the ongoing antimicrobial resistance (AMR) global crisis due to the increase in the use of antibiotics to treat COVID-19 patients, disruptions to infection prevention and control practices in o...verwhelmed health systems, and diversion of human and financial resources away from monitoring and responding to AMR threats. Moreover, AMR is likely to have caused more COVID-19 deaths, as secondary bacterial infections can worsen the outcome of severe and critical COVID-19 illness. Therefore, it is more urgent than ever to prioritize efforts towards AMR containment and support countries to improve the detection, characterization and rapid response to emerging AMR.

Of the 50 antibiotics in the pipeline, 32 target WHO priority pathogens but the majority have only limited benefits when compared to existing antibiotics. Two of these are active against the multi-drug resistant Gram-negative bacteria, which are spreading rapidly and require urgent solutions.
Gr...am-negative bacteria, such as Klebsiella pneumoniae and Escherichia coli, can cause severe and often deadly infections that pose a particular threat for people with weak or not yet fully developed immune systems, including newborns, ageing populations, people undergoing surgery and cancer treatment.
The report highlights a worrying gap in activity against the highly resistant NDM-1 (New Delhi metallo-beta-lactamase 1), with only three antibiotics in the pipeline. NDM-1 makes bacteria resistant to a broad range of antibiotics, including those from the carbapenem family, which today are the last line of defence against antibiotic-resistant bacterial infections.

Historically, the discovery of the sulfa drugs in the 1930s and the subsequent development of penicillin during World War II ushered in a new era in the treatment of infectious diseases. Infections that were common causes of death and disease in the pre-...antibiotic era - rheumatic fever, syphilis, cellulitis and bacterial pneumonia - became treatable, and over the next 20 years most of the classes of antibiotics that find clinical use today were discovered and changed medicine in a profound way. The availability of antibiotics enabled revolutionary medical interventions such as cancer chemotherapy, organ transplants and essentially all major invasive surgeries from joint replacements to coronary bypass. Antibiotics, though, are unique among drugs in that their use precipitates their obsolescence. Paradoxically, these cures select for organisms that can evade them, fueling an arms race between microbes, clinicians and drug discoverers.

Antimicrobials are medicines, including antibiotics, antivirals, antifungals, and antiparasitics, that are used to prevent and treat infections in humans, animals, and plants. Antimicrobial Resistance (AMR) arises when bacteria, viruses, fungi, and parasites no longer respond to these medicines, ren...dering them ineffective and making infections more difficult to treat. This resistance increases the risk of disease spread, severe illness, disability, and death. Although AMR is a natural phenomenon driven by genetic
changes in pathogens, it is significantly accelerated by human activities such as the misuse and overuse of antimicrobials in healthcare, agriculture, and animal husbandry.

Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Over a period of two decades, under-5 mortality rate in Bangladesh has declined by 66% from 133 per 1000 live births in 1993-94 to 45 per 1000 live births in 2017-18. The country reached the MDG-4 goal in the reduction of child mortality on time. However, the comparison of neonatal and under-5 morta...lity rates in Bangladesh over the same years reveals that the reduction in the neonatal mortality rate was much slower than the child mortality rate. This led to a rise in the proportion of neonatal deaths in overall under-five deaths from 40% in 1993-1994 to 67% percent in 2017-2018. More than 75% of neonatal deaths occur within the first 7 days. To achieve SDG target 3.2, Bangladesh has to further reduce under-5 mortality rate by 44% and newborn deaths by 60%. Infection is the leading cause of preventable deaths among the neonates and the young infants and the standard recommendations for treating severe bacterial infections in infants under 2 months of age include hospitalization and 7-10 days of parenteral therapy.

Pakistan Global Antibiotic Resistance Partnership (GARP) was formed in the wake of international and national efforts for AMR curtailment. A group of experts from microbiology, infectious diseases and veterinary medicine formed a core group at the organizational meet...ing of GARP in Kathmandu, Nepal in July 2016. In the meeting, this core group was expanded to include other members from different sectors with the selection of the Chair and co-chairs. These were asked to serve on a voluntary basis, in their own individual capacities, with no personal gains, or gains to the institutions to which they are affiliated. The first phase of GARP took place from 2009 to 2011 and involved four countries: India, Kenya, South Africa and Vietnam. Phase one culminated in the 1st Global Forum on Bacterial Infections, held in October 2011 in New Delhi, India. In 2012, phase two of GARP was initiated with the addition of working groups in Mozambique, Tanzania, Nepal and Uganda. Phase three has added Bangladesh, Lao PDR, Nigeria, Pakistan and Zimbabwe to the network to date.

Antibiotics have been a critical public health tool since the discovery of Penicillin in 1928, saving the lives of millions of people around the world. In developing country like ours, where the burden of treatable disease is very high and access to health facilities and laboratories is difficult, a...ntibiotics have long acted as miracle drugs. Today, however, the emergence of drug
resistance in bacteria is reversing the miracles of the past eighty years, with drug choices for the treatment of many bacterial infections becoming increasingly limited, expensive, and in some cases, nonexistent. Diseases previously regarded as relatively easy to manage are much harder to treat as doctors must use “last-resort” drugs that are more costly, take longer to work
and are often unavailable or unaffordable in developing countries. Moreover, regular prescription of antibiotics, random treatment, over the counter sales, inadequate dosage, inclusion of antibiotics in animal feeds and agriculture has contributed equally to emergence of antibiotics resistance as silent epidemic within the country.

Emergence of antimicrobial resistance is a result of the use, overuse and misuse of antibiotics both in humans and animals. In Ethiopia, there are indications on the misuse of antibiotics by health care providers’, unskilled practitioners, and drug consumers. These coupled with rapid spread of res...istant bacteria and inadequate surveillance contributed to the problem. Bacterial infections are the major causes of death in Ethiopia. Studies on antibacterial resistance and on bacterial infections have shown that emerging antibacterial resistance threatens the management of bacterial infections; however, the prevention and containment has received far too little attention.
