Treatment with antibiotics is one of the most extreme perturbations to the human microbiome. Even standard courses of antibiotics dramatically reduce the microbiome's diversity and can cause transitions to dysbiotic states. Conceptually, this is often described as a 'stability landscape': the microbiome sits in a landscape with multiple stable equilibria, and sufficiently strong perturbations can shift the microbiome from its normal equilibrium to another state. However, this picture is only qualitative and has not been incorporated in previous mathematical models of the effects of antibiotics...

There is an urgent global need for a safe macrofilaricide drug to accelerate elimination of the neglected tropical diseases onchocerciasis and lymphatic filariasis. From an anti-infective compound library, the macrolide veterinary antibiotic, tylosin A, was identified as a hit against Wolbachia This bacterial endosymbiont is required for filarial worm viability and fertility and is a validated target for macrofilaricidal drugs. Medicinal chemistry was undertaken to develop tylosin A analogs with improved oral bioavailability...

Land application of animal manure could change the profiles of antibiotic resistant bacteria (ARB), antibiotic resistance genes (ARGs) and bacterial communities in receiving soils. Using high-throughput real-time quantitative PCR and 16S rRNA amplicon sequencing techniques, this study investigated the ARGs and bacterial communities in field soils under various crop (corn and pasture) and manure (swine and dairy) managements, which were compared with those of two non-manured reference soils from adjacent golf course and grassland...

INTRODUCTION: Very low birth weight (VLBW) neonates (< 1500 g) are commonly exposed to prolonged antibiotic courses related to concerns for presumed early onset sepsis often with unclear indications. While antibiotics can be life-saving medications, prolonged antibiotic exposure (> 5 days) increases an infant's risk for necrotizing enterocolitis, late onset sepsis, colonization or infection with resistant organisms, and death. The aim of this study is to describe clinical and laboratory factors that influence the length of initial antibiotic courses in VLBW neonates...

Background: The duration of antibiotic therapy for bacteremia due to Enterobacteriaceae is not well-defined. We sought to evaluate the clinical outcomes with shorter versus longer-course treatment. Methods: We performed a systematic search of the PubMed and EMBASE databases through May 2018. Studies presenting comparative outcomes between patients receiving antibiotic treatment for ≤10 days ("short-course") and those treated for >10 days ("long-course") were considered eligible. Results: Four retrospective cohort studies and one randomized controlled trial comprising 2,865 patients met the inclusion criteria...

In persons with cystic fibrosis (CF), decreased airway microbial diversity is associated with lower lung function. Conflicting data exist on the impact of short-term antibiotics for treatment of acute pulmonary exacerbations. However, whether differences in antibiotic exposure impacts airway microbiome changes has not been studied. We hypothesized that subtherapeutic beta-lactam antibiotic exposure, determined by the pharmacokinetics and pharmacodynamics (PK/PD) after intravenous (IV) antibiotic administration, would be associated with different patterns of changes in CF airway microbial diversity...

This study trained long short-term memory (LSTM) recurrent neural networks (RNNs) incorporating an attention mechanism to predict daily sepsis, myocardial infarction (MI), and vancomycin antibiotic administration over two week patient ICU courses in the MIMIC-III dataset. These models achieved next-day predictive AUC of 0.876 for sepsis, 0.823 for MI, and 0.833 for vancomycin administration. Attention maps built from these models highlighted those times when input variables most influenced predictions and could provide a degree of interpretability to clinicians...

Probiotics are living microorganisms that confer health benefits to the host when administered in adequate amounts; however, dead bacteria and their components can also exhibit probiotic properties. Bifidobacterium and strains of lactic acid bacteria are the most widely used bacteria that exhibit probiotic properties and are included in many functional foods and dietary supplements. Probiotics have been shown to prevent and ameliorate the course of digestive disorders such as acute, nosocomial, and antibiotic-associated diarrhea; allergic disorders such as atopic dermatitis (eczema) and allergic rhinitis in infants; and Clostridium difficile-associated diarrhea and some inflammatory bowel disorders in adults...

Insights into the Pathogenesis of Inflammatory Bowel Diseases: Genetics and Microbiota Abstract. An inadequate immune response against bacteria of the gastrointestinal tract is the basic mechanism mediating the pathophysiology of inflammatory bowel diseases (IBD). The risk of IBD is partially heritable and approximately 12 % of patients have a family history of IBD. Large genome-wide association studies (GWAS) were able to identify 240 genetic regions associated with IBD. Many of the implicated genes have a function in the immune system, are associated with primary immunodeficiencies or the defense against mycobacteria...

Gut microbiota dysbiosis has been considered the essential element in the pathogenesis of multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE). Antibiotics were administered orally to Dark Agouti (DA) rats early in their life with the aim of perturbing gut microbiota and investigating the effects of such intervention on the course of EAE. As a result, the diversity of the gut microbiota was reduced under the influence of antibiotics. Mainly, Firmicutes and Actinobacteria were replaced by Proteobacteria and Bacteroidetes, while decreased proportions of Clostridia and Bacilli classes were accompanied by an increase in Gamma-Proteobacteria in antibiotic-treated animals...

BACKGROUND: It is well known that antibiotic use is the main driver for the increasing problems with resistant bacteria. Consequently, some countries have recommended shortening the duration of antibiotic treatment of community-acquired pneumonia (CAP). The aim of this study was to investigate if the effectiveness of a short-course antibiotic is comparable to a longer course of antibiotics in adults with CAP and to assess if the duration of an antibiotic course influences the development of resistant bacteria...

Bacteremia due to gram-negative bacilli (GNB) is one of the most frequent causes of admission and prolongation of hospital stay. Nevertheless, optimal duration of antibiotic treatment is not clearly established. We designed an observational, prospective study of a cohort of adult patients with uncomplicated GNB bacteremia. They were classified according to the duration of treatment in short (7-10 days) or long (> 10 days) course. Mortality and bacteremia recurrence rate were evaluated, and propensity score for receiving short-course treatment was calculated...

Exacerbations of asthma are still responsible for 900 deaths per year in France, most of which are considered preventable. They have a major impact on the quality of life of patients and are responsible for a large part of the socio-economic cost of asthma in France. Exacerbations of asthma can be partly prevented by inhaled corticosteroid treatment as controller therapy, at a dose adapted to the level of control of symptoms and the management of aggravating factors. Every patient should benefit from a written action plan that allows them to start oral corticosteroid therapy as soon as possible during an exacerbation...
