antibacterial, antifungal and antioxidant activities of methanolic crude extracts from aerial parts of four arnebia species namely arnebia fimbriopetala, arnebia linearifolia, arnebia garandiflora, arnebia tubata were screened. total phenolic contents were determined by folin-ciocalteu procedure and ranged from 2.2 ± 0.13 (a. fimbriopetala) to 1.6 ± 1.0 mg (arnebia tubata) gallic acid µmol equi...
an important part of plant in vitro techniques is the sterilization of explants and the maintenance of aseptic conditions. ideally, sterilizing materials should be effective on a vast range of microorganisms at low density. nowadays, the use of compounds such as essential oils (eos) and nanoparticles is applicable in microbiology studies. the main objective of this experiment was to study the s...
background & aim: in this study, is done during one-year research on blue–green and green algae for antimicrobial activity in mashhad suburb. aqueous, ether, and methanol extracts from 44 species blue – green algae and green algae were examined for antimicrobial properties against four bacteria (tow positive gram bacteria and tow negative gram bacteria) and tow fungous. material & meth...
BACKGROUND The development of antimicrobial guidelines is one way in which institutions attempt to control emerging resistance, but the real challenge falls on promoting and ensuring adherence to these guidelines. Investigating reasons for the prescribing of alternative antimicrobial agents outside of these guidelines is crucial for modifying practices that may adversely impact institutional an...
BACKGROUND In haematology/oncology units, the frequent and heavy use of broad-spectrum antimicrobials can lead to outbreaks of antimicrobial resistance. Increasing antimicrobial heterogeneity might be a useful strategy for preventing such resistance. METHODS A real-time antimicrobial use density (AUD) monitoring system (RAMS) was developed to precisely assess antimicrobial heterogeneity. This...
Antimicrobial stewardship is pivotal to improving patient outcomes, reducing adverse events, decreasing healthcare costs, and preventing further emergence of antimicrobial resistance. In an era in which antimicrobial resistance is increasing, judicious antimicrobial use is the responsibility of every healthcare provider. Antimicrobial stewardship programs (ASPs) have made headway in improving a...
The role of antimicrobial management programs in optimizing antibiotic prescribing within hospitals.
Managing serious infections is a balance between providing timely and appropriate broad-spectrum empirical therapy for individual patients, which has been consistently shown to improve outcomes, and reducing unnecessary use of antimicrobial agents, which may contribute to the development of antimicrobial resistance. To control the spread of antimicrobial resistance, hospitals commonly implement...
Antimicrobial agents are some of the most widely, and often injudiciously, used therapeutic drugs worldwide. Important considerations when prescribing antimicrobial therapy include obtaining an accurate diagnosis of infection; understanding the difference between empiric and definitive therapy; identifying opportunities to switch to narrow-spectrum, cost-effective oral agents for the shortest d...
conclusions optimization of medium composition and synergistic antimicrobial activity on the cyanobacteria could lead to production of effective antimicrobials. results c. leptolyngbya had antimicrobial activity individually and in synergy with antibiotics against gram-positive and gram-negative bacteria. the highest activity of the chloroform extract was on gram positive strains and its effect...
Surveillance and monitoring studies of antimicrobial resistance in bacteria of human and animal origin and antimicrobial consumption in humans and animals have been conducted in various countries throughout the world. In the veterinary field, in particular, programmes have been installed which target bacteria of zoonotic, foodborne and/or veterinary relevance. Each year, the European Surveillan...
