objective(s):   the ongoing increasing antibiotic resistance is one of the biggest challenges faced by global public health. the perennial need for new antimicrobials against a background of increasing antibiotic resistance in pathogenic and opportunistic microorganisms obliges the scientific community to constantly develop new drugs and antimicrobial agents. lichens are known prolific sources ...

objectives: the aim of this study was to evaluate the effect of gutta percha/ah26 and resilon/realseal se on residual antimicrobial activity of chlorhexidine (chx) in human root dentin and suggest the best filling material when chx is used as final irrigant. materials and methods: one-hundred and forty-four single-rooted human teeth were selected for this study. canals were instrumented to the ...

background: infectious diarrhoea is an emergent problem in both developing and developed countries for high rates of mortality in infants. in recent years, drug resistance to microbial pathogens has been commonly reported from all over the world. medicinal plants represent a rich source of antimicrobial agents. plants are used medicinally in different countries especially in india and are a sou...

BACKGROUND Inappropriate use of antimicrobials is linked to the development and spread of drug-resistant pathogens and is associated with increased morbidity, mortality, lengths of hospital stay, and health care costs. "Antimicrobial stewardship" is the umbrella term for an evidence-based knowledge translation strategy involving comprehensive quality improvement activities to optimize the use o...

Consumption of antimicrobial drugs, such as antibiotics, is linked with antimicrobial resistance. Surveillance of antimicrobial drug consumption is therefore an important element in dealing with antimicrobial resistance. Many countries lack sufficient surveillance systems. Usage of web mined data therefore has the potential to improve current surveillance methods. To this end, we study how well...

In the last decades, considerable attention has been paid to the collection of antimicrobial resistance data, with the aim of monitoring non-wild-type isolates. This monitoring is performed based on minimum inhibition concentration (MIC) values, which are collected through dilution experiments. We present a semi-parametric mixture model to estimate the entire MIC density on the continuous scale...

Over the past decade, levels of bacterial resistance to antibiotics have risen dramatically and "superbugs" resistant to most or all available agents have appeared in the clinic. Thus there is a growing need to discover and introduce new drugs. One potential source of novel antibiotics is the cationic antimicrobial peptides, which have been isolated from most living entities as components of th...

This article summarizes the current literature describing how antimicrobial stewardship interventions impact antimicrobial resistance. Discussion includes why we need stewardship, how to collaborate with team members, and the evidence of stewardship's impact on resistance.

BACKGROUND Antimicrobial consumption in veterinary medicine is of great importance. Increased awareness by the public and media has led to demands for decreased use of antimicrobials in pigs. This study aimed to identify risk factors for regular oral antimicrobial consumption in Swiss fattening pig farms, and to quantify the amount of antimicrobial active substances administered orally to pigs ...
