Antibiotic resistance is the direct deleterious consequence of two synergistic causes linked to human activity: the massive use of antibiotics in human and animal health, which leads to the selection of the most resistant bacteria, and the spread of these selected resistant bacteria, directly by cross-transmission within human and animal populations and indirectly via the environment. The "one health" concept enables an integrated approach of the various components of the issue, linking human, animal and environmental ecosystems and their dynamics...

Mycobacterium abscessus is a fast-growing non-tuberculous mycobacteria complex causing pulmonary infections, comprising the subspecies abscessus, massiliense and bolletii. Differences are based predominantly on natural inducible macrolide resistance, active in most Mycobacterium abscessus spp abscessus species and in Mycobacterium abscessus spp bolletii but inactive in Mycobacterium abscessus spp massiliense. Therapy consists in long-term treatment, combining multiple antibiotics. Prognosis is poor, as only 40% of patients experience cure...

Febrile neutropenia is a frequent complication of cancer treatment and is associated with an increased risk of morbidity and mortality. However, standardization in the management of neutropenic fever has led to a reduction in its complications. The duration and type of antibiotic therapy differ according to guidelines, particularly in cases of febrile neutropenia of unknown origin. Continuation of antibiotic treatment until resolution of neutropenia has historically been recommended but exposes patients to prolonged periods of broad-spectrum antibiotic therapy...

The recommendations for the general public as well as the tools offered to healthcare professionals for their practices are consistent with the 2022-2025 national strategy for the prevention of infections and antibiotic resistance. They therefore cover both infection prevention and the proper use of antibiotics.

Preserving the effectiveness of our antibiotics against pathogenic bacteria is a major public health issue, which is why the World Health Organization has made the fight against antibiotic resistance one of its ten priorities. The fight against antibiotic resistance must be implemented at international, national and local levels. Nurses, in close contact with patients, have a fundamental role to play in both pillars of the strategy implemented in France: in the prevention and control of infections, of course, but also in the proper use of antibiotics...

PURPOSE: To compare the safety and efficacy of fortified antibiotics and fluoroquinolones in the treatment of bacterial keratitis. METHODS: PubMed, EMBASE, Cochrane Library, CNKI, Wanfang database and VIP database were systematically searched for randomized controlled trials (RCT) of treatment of bacterial keratitis with fortified antibiotics and fluoroquinolones. Rev Man 5.3 software was used to analyze outcome index cure rate, time to cure, and adverse events in a meta-analysis...

The treatment of infectious diseases in geriatric medicine is a complex subject. Diagnosis is often difficult, as is the correct indication for antibiotic therapy. To combat antibiotic resistance, we need to limit unnecessary antibiotic prescriptions and prevent the onset of bacterial infections, notably through vaccination.

Melioidosis is an infectious, tropical and emerging disease, due to a bacterium of the hydrotelluric environment, Burkholderia pseudomallei, which is considered as a potential biological weapon because of its exceptional resistance and virulence capacities. Its worldwide spread, outside the original endemic foci of Southeast Asia and Australia, is favoured by global warming and the diabetes mellitus pandemic, which is the main predisposing factor.In humans, melioidosis is an opportunistic infection, following professional (rice farmers, soldiers) or accidental contamination, by inhalation or inoculation...

The fight against antibiotic resistance must incorporate the "One Health" concept to be effective. This means having a holistic approach embracing the different ecosystems, human, animal, and environment. Transfers of resistance genes may exist between these three domains and different stresses related to the exposome may influence these transfers. Various targeted or pan-genomic molecular biology techniques can be used to better characterise the dissemination of bacterial clones and to identify exchanges of genes and mobile genetic elements between ecosystems...

NEW ANTIBIOTICS TO DEAL WITH ANTIBIOTIC RESISTANCE. The current increase in antibiotic resistance exposes to the risk of therapeutic impasse. To deal with this public health problem, developing new antibiotics that are effective (directly or in combination with older drugs) against these multi-resistant bacteria seems important. Over the last 10 years, new drugs (beta-lactams, beta-lactamase inhibitors, cyclin and carbapenems) have been developed against Gram-negative bacteria. A new oxazolidinone, two glycopeptides and a quinolone have been developed against Gram-positive bacteria...

INTRODUCTION: pharmacy students are future providers of pharmaceutical care and should play a critical role in combating bacterial resistance (BR). The purpose of this study was to evaluate the knowledge and practice of students at the end of pharmacy course relating to BR and antibiotic use. METHODS: we conducted a cross-sectional, descriptive and analytic study. The study population consisted of students enrolled in Master 2 and PhD in Pharmacy at the Cheikh Anta Diop University over the year 2019...

OBJECTIVES: To assess the impact of interventions of a clinical pharmacist in a unit of orthopaedic surgery specialized in bone and joint infections. METHODS: Daily, in routine, a clinical pharmacist analysed medication prescribed to inpatients via a computerized physician order entry (CPOE) (Phedra software). His attention was particularly focused on the impact of antibiotics on other medications. For this study, all of the pharmacist interventions (PI) have been retrospectively collected, then anonymized, and assessed over a two-month period...

Reading an antibiogram, however simple it may appear at first glance, is full of sometimes implicit but valuable information in the daily practice of the physician. A more subtle reading requires knowledge in the microbiology and pharmacology fields, even more so in the presence of resistant bacteria. The aim of this article is to provide the clinician with some keys to read and understand an antibiogram in the current context.

The aim of this study was to evaluate the current use of antibiotics by Swiss equine veterinarians and to compare the results with a similar study from 2013 before the introduction of the web tool Antibiotic Scout. The survey was sent to equine veterinarians according to the member database of the Swiss Veterinary Association (GST, SVS). The demographic data of the respondents and their antibiotics usage were collected. In addition, six different case scenarios were presented with questions to their potential antibiotic usage, active substance/preparation and the dosing scheme...

BACKGROUND: The phenomenon of antibiotic resistance shows no sign of stopping, despite global policies to combat it that have been in place for several years. The risk of forms of pathogenic microorganisms that are increasingly resistant to common antibiotics has led health authorities around the world to pay greater attention to the phenomenon. The worrying situation, has led to further recommendations from the World Health Organization (WHO) and national recommendations in Italy through the new National Plan against Antibiotic Resistance 2022-2025 (PNCAR 2022-2025)...

BACKGROUND: Among hospitalized patients, a 48-hour window from time of hospitalization defines nosocomial infections and guides empiric antibiotic selection. This time frame may lead to overuse of broad-spectrum antibiotics. Our primary objective was to determine the earliest and median time since hospital admission to acquire antibiotic-resistant pathogens among patients admitted to the intensive care unit (ICU) of an academic, tertiary care hospital. METHODS: Retrospective chart review was conducted for adult patients admitted to the ICU from home or another hospital within the same health authority in 2018, to identify the time to acquisition of hospital-associated pathogens: methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, extended-spectrum beta-lactamase (ESBL)-producing Enterobacterales, non-ESBL ceftriaxone-resistant Enterobacterales, Pseudomonas aeruginosa, and Stenotrophomonas maltophilia ...

Infections commonly occur terminally ill oldest patients in palliative care and questioned about antimicrobial use. The aim of this study was to describe practitioners' habits. METHOD: ancillary study on antibiotic modalities according to the setting of care from a national practices survey based on self administered questionnaire sent by e-mail in 2017. RESULTS: 220 practitioners/327 used antibiotic, 136 worked in hospital department (52 geriatricians), 20 nursing home and 64 general practitioners (GP)...
