Increasing antibiotic resistance is a major public health concern. Fluoroquinolones are used to treat and prevent poultry diseases worldwide. Fluoroquinolone resistance rates are high in their countries of use. The aim of this study was to evaluate the effect of an acids-based feed additive, as well as fluoroquinolone antibiotics, on the prevalence of antibiotic-resistant E. coli. A total of 480 broiler chickens (Ross 308) were randomly assigned to 3 treatments: a control group receiving a basal diet; a group receiving a feed additive (FA) based on formic acid, acetic acid and propionic acid; and an antibiotic enrofloxacin (AB) group given the same diet, but supplemented with enrofloxacin in water...

Wolfgang Pfützner, Hinnerk Wulf
The diagnostic evaluation of perioperative anaphylaxia is of great importance for the medical care of the affected persons in the context of renewed interventions in general anesthesia. The most frequent triggers include muscle relaxants, antibiotics, latex and analgesics of the type of the cyclooxygenase inhibitors, but other perioperatively administered drugs such as opioids, anesthetics, benzodiazepines, dyes, disinfectants and even corticosteroids or drug additives may also be the cause in rare cases. The most important aim is therefore the identification of the responsible drug, for which a near-time allergological diagnosis should be carried out within the first 4 weeks to 6 months after the reaction...

Spondylodiscitis is a rare but serious infection of the spine. Recognised methods of treatment include immobilisation and systemic antibiotics. However, available data for specific and recommendations for continuing treatment are also rare. The aim of the present study is the optimisation of the therapy of spondylodiscitis using a clinical pathway that depends on a classification of spondylodiscitis. From 1 October 1998 to 31 December 2013, a classification of the severity of spondylodiscitis was established, including specific treatment recommendations...

Rapid emergence of antibiotic resistance (AR) in developing countries is posing a greater health risk and increasing the global disease burden. AR proliferation mediated by treated/untreated discharges from sewage treatment plants (STPs) is a prime public health concern. Efficient sewage treatment is among our key defenses against the dissemination of infectious diseases. The present study aims to estimate the efficiency of aerobic [activated sludge process (ASP) and modified trickling filter (MTF)] and anaerobic reactors (anaerobic flow-through reactor) along with the three disinfection techniques (UV, ozone and chlorination) in reducing ARB and ARGs present in the domestic sewage...

In this work we developed new antibacterial composite materials using polydopamine (PDA) to trigger the deposition of silver nanoparticles (AgNPs) onto calcium phosphates, namely octacalcium phosphate (OCP) and α-tricalcium phosphate (αTCP). Functionalization of OCP and αTCP with a self-polymerized polydopamine layer was obtained by soaking the calcium phosphates in dopamine solution. The PDA surface of functionalized calcium phosphates (OCPd and αTCPd) promoted the deposition of AgNPs by reducing silver ions when soaked in a silver nitrate solution...

Microbial strains are amazingly clever by homeostasis of their own survival and optimization for the overproduction of a desired phenotype, for example drugable secondary metabolites through coordination of key genes overexpression and media optimizations. Besides their pesticide activities, avermectins (AVMs) are identified as potent antibiotic agents for a wide range of drug-resistant pathogens by a high-throughput synergy screening strategy. To rewire the genetic circuitry controlling low yields, we summarized the work on balancing the biological chassis with functional parts, and optimized their dynamical process, as well as predicted favorable effective overproduction of AVMs by 5Ms strategy...

Antibiotic lethality is a complex physiological process, sensitive to external cues. Recent advances using systems approaches have revealed how events downstream of primary target inhibition actively participate in antibiotic death processes. In particular, altered metabolism, translational stress and DNA damage each contribute to antibiotic-induced cell death. Moreover, environmental factors such as oxygen availability, extracellular metabolites, population heterogeneity and multidrug contexts alter antibiotic efficacy by impacting bacterial metabolism and stress responses...

REVIEW
Shelly Hen-Avivi, Roi Avraham
Despite the availability of antibiotics and immunization, infectious diseases remain a major cause of malignancy and death worldwide. Yet, it is well documented that for most infectious agents, clinical disease develops in only a small minority of infected individuals. There is, in fact, great heterogeneity in infection outcome, from complete clearance of the pathogen to severe illness. Understanding this variation remains elusive, despite its great potential to equip us with new tools for the treatment of infectious diseases...

Importance: Surgical site infections (SSIs) after colorectal surgery remain a significant complication, particularly for patients with cancer, because they can delay the administration of adjuvant therapy. A combination of oral antibiotics and mechanical bowel preparation (MBP) is a potential, yet controversial, SSI prevention strategy. Objective: To determine the association of the addition of oral antibiotics to MBP with preventing SSIs in left colon and rectal cancer resections and its association with the timely administration of adjuvant therapy...

BACKGROUND: Infection is a common complication in acute stroke. Whether or not preventive antibiotics reduce the risk of infection or even lead to a favorable outcome and reduction of mortality after a stroke still remains equivocal. This review was performed to update the current knowledge on the effect and possible benefits of prophylactic antibiotic therapy in patients with stroke. METHODS: A systematic review and meta-analysis of preventive antibiotics`effect on the incidence of infection, favorable outcome (mRS≤2) and mortality in patients with acute stroke is performed with relevant randomized controlled trials...

Ototoxicity is a significant side effect of a number of drugs, including the aminoglycoside antibiotics and platinum-based chemotherapeutic agents that are used to treat life-threatening illnesses. Although much progress has been made, the mechanisms that lead to ototoxic loss of inner ear sensory hair cells (HCs) remains incompletely understood. Given the critical role of protein phosphorylation in intracellular processes, including both damage and survival signaling, we screened a library of kinase inhibitors targeting members of all the major families in the kinome...
