overuse of antibiotics

Xuan Zhang, Yi-Chi Zhang, Jia-Wei Zhang
Chloramphenicol (CAP), as a broad-spectrum antibiotic, has been worldwide banned for using in the food producing animals due to its overuse may cause severe threats to public health. It is therefore highly desirable to develop facile, selective and sensitive biosensor for CAP detection and monitoring in drug and foodstuff samples. In this work, three-dimensional reduced graphene oxide (3DRGO) architectures were prepared through a green and template-free approach and used as active electrode materials to develop a highly selective electrochemical sensor for CAP detection...

Misconception about antibiotics use among the public has been widely outlined to be a main reason for inappropriate use of antibiotics including failure to complete treatment, skipping of doses, re-use of leftover medicines and overuse of antibiotics. The study was devised to evaluate whether education might be a potential strategy to promote safer use of antibiotics and reducing self-medication. Two hundred seventy one adults were asked to complete two questionnaires; a pre and posteducation. The questionnaires comprised of three parts consisting of 17 statements assessing the knowledge on: appropriate use, safe use and resistance of antibiotics...

The widespread overuse of antibiotics in aquaculture has led to the emergence of antibiotic-resistance shrimp pathogens, the negative impact on shrimp gut microbiota, and the presence of antimicrobial residues in aquaculture products, with negative consequences on human health. Alternatively, probiotics have positive effects on immunological responses and productive performance of aquatic animals. In this study, three probiotic bacteria, (Bacillus licheniformis MAt32, B. subtilis MAt43 and B. subtilis subsp...

The performance and microbial community of a sequencing batch biofilm reactor (SBBR) treating synthetic mariculture wastewater were evaluated under long-term exposure to norfloxacin (NFX) due to the overuse of antibiotics during the mariculture. The COD and NH4(+)-N removals had no distinct change at 0-6mgL(-1) NFX and were inhibited at 6-35mgL(-1) NFX. The specific oxygen uptake rate (SOUR), specific ammonium oxidation rate (SAOR), specific nitrite oxidation rate (SNOR) and specific nitrate reduction rate (SNRR) of the biofilm kept a decreasing tendency with the increase of NFX concentration from 0 to 35mgL(-1)...

Travellers' diarrhoea caused by enteric protozoa like Entamoeba histolytica is among the most common protozoan diseases in developing countries. In developing countries, amoebiasis is the second most prevalent protozoan disease. This protozoan parasite is often known to coexist as a part of the normal gut microbiota. It is estimated that around 50-60 % of population in developing countries might be harbouring Entamoeba in an asymptomatic manner. Due to physiological perturbation or upon immuno-compromise, it can become virulent and then cause diarrhoea, bloody stools and may invade other organs if left untreated...

Background.  Urinary tract infection (UTI) is one of the most common diagnoses leading to an antibiotic prescription for women seeking ambulatory care. Understanding current national outpatient antibiotic prescribing practices will help ongoing stewardship efforts to optimize antibiotic use; however, information on recent national outpatient antibiotic prescribing trends for UTI is limited. Methods.  We analyzed the National Ambulatory Medical Care and National Hospital Ambulatory Medical Care Survey datasets from 2002 to 2011...

The "antibiotic era", characterized by the overuse and misuse of antibiotics, over the last half-century has culminated in the present critical "era of resistance". The treatment of bacterial infections is challenging because of a decline in the current arsenal of useful antibiotics and the slow rate of new drug development. The discovery of a new gene (mcr-1) in 2015, which enables bacteria to be highly resistant to polymyxins (such as colistin), the last line of antibiotic defence left, heralds a new level of concern as this gene is susceptible to horizontal gene transfer, with alarming potential to be spread between different bacterial populations, suggesting that the progression from "extensive drug resistance" to "pan-drug resistance" may be inevitable...

Antibiotic overuse has promoted the spread of antibiotic resistance. To compound the issue, treating individuals dually infected with antibiotic-resistant and antibiotic-vulnerable strains can make their infections completely resistant through competitive release. We formulate mathematical models of transmission dynamics accounting for dual infections and extensions accounting for lag times between infection and treatment or between cure and ending treatment. Analysis using the Next-Generation Matrix reveals how competition within hosts and the costs of resistance determine whether vulnerable and resistant strains persist, coexist, or drive each other to extinction...

INTRODUCTION: The incidence of urinary tract infections caused by Extended-Spectrum Beta Lactamase (ESBL) producing Escherichia coli (E. coli) strains due to long term and overuse of broad-spectrum cephalosporine is on the rise. CTX beta-lactamase type, a broad-spectrum beta-lactamase, has been expanding in many countries. The ctx gene is harbored on a plasmid that is spread between Enterobacteriaceae family, especially in E. coli. The aim of this study was to determine the pattern of antimicrobial resistance and investigate the prevalent ESBL phenotype and the ctx-M gene in E...

: Horizontal acquisition of novel chromosomal genes is considered to be a key process in the evolution of bacterial pathogens. However, identification of gene presence or absence could be hindered by the inconsistencies in bacterial genome annotations. Here, we perform a cross-annotation of omnipresent core and mosaic accessory genes in the chromosome of Salmonella enterica serovar Typhimurium, across a total of 20 fully-assembled genomes deposited into GenBank. Cross-annotation resulted in 32% increase in the number of core genes and 3 fold drop in genes identified as mosaic (i...

BACKGROUND: There is a rapid emergence of multiple resistant gram-negative bacteria due to overuse of antibiotics in the treatment of infections. Biofilms consist of polymicrobial communities that survive the host's defense system. The key bacteria in biofilms are slow growing and support an attachment and rapid growth of other microorganisms. Current antimicrobial strategies often fail due to poor diagnosis of key pathogens in biofilms. The study aims to develop anti-bacterial human antibodies in vitro from patients who had recently undergone a systemic infection by pathogenic bacteria and to use these antibodies as a tool for detecting bacteria in biofilms...

BACKGROUND: Given the increase of antibiotic resistant bacteria the requirement for hospitals and ambulatory services to collect and analyze antibiotic consumption data was stipulated in the Protection against Infection Act (IfSG) in 2011. It is the duty of the public health offices to supervise the compliance with these specifications. Below, the antibiotic consumption data of all hospitals in Frankfurt am Main between 2012 and 2014 are reported and the supervisory activities presented...

BACKGROUND: Many lines of scientific research suggest that Autism Spectrum Disorders (ASDs) may be associated with alterations in the enteric ecosystem, including alterations of the enteric macrobiome (i.e. helminthes and fungi) and changes in predominant microbiome species, particularly a reduction in microbiome diversity. METHODS: We performed and comprehensive review of the literature and summarized the major findings. RESULTS: These alterations are believed to be due to a variety of factors including changes in the post-industrial society related to decreased exposure to symbiotic organisms, increased human migration, overuse of antibiotics and changes in dietary habits...

Antimicrobial resistance has become a major global public health security problem that needs coordinated approaches at regional, national and international levels. Antibiotic overuse and the failure of control measures to prevent the spread of resistant bacteria in the healthcare environment have led to an alarming increase in the number of infections caused by resistant bacteria, organisms that resist many (multi-drug and extensively drug-resistant strains), if not all (pan-drug-resistant bacteria) currently available antibiotics...

Clinical diagnosis of acute infectious diseases during the early stages of infection is critical to administering the appropriate treatment to improve the disease outcome. We present a data driven analysis of the human cellular response to respiratory viruses including influenza, respiratory syncytia virus, and human rhinovirus, and compared this with the response to the bacterial endotoxin, Lipopolysaccharides (LPS). Using an anomaly detection framework we identified pathways that clearly distinguish between asymptomatic and symptomatic patients infected with the four different respiratory viruses and that accurately diagnosed patients exposed to a bacterial infection...

Antibiotics are overused in many European countries, particularly Greece, leading to emerging antimicrobial resistance with sustained high mortality among hospitalised patients. Limited data are available regarding factors influencing people's knowledge and the impact of public campaigns on antibiotic misuse. Patients' beliefs regarding antibiotics were investigated in the outpatient clinic of a university hospital in Athens, Greece. A questionnaire-based survey was conducted to examine patients' opinions on antibiotic use in the waiting room of the outpatient clinic...
