A panel of national experts was convened by the Brazilian Infectious Diseases Society in order to determine the recommendations for outpatient parenteral antimicrobial therapy (OPAT) in Brazil. The following aspects are covered in the document: organization of OPAT programs; patient evaluation and eligibility criteria, including clinical and sociocultural factors; diagnosis of eligibility; veno...

The present study was undertaken to investigate the chemical composition and effectiveness of the essential oil isolated from Echinophora spinosa on different bacterial and fungal species. Chemical analysis (GC/MS) showed that δ3-carene (60,86 %), α-phellandrene (7,12%), p-cymene (6,22 %), myrcene (4,82 %) and β-phellandrene (2,73 %) were dominant components in this oil. Essential oil tested sh...

in the present study, the antimicrobial tests of patchouli oil were studied by using molecular docking technology and antimicrobial test in vitro. five biological macromolecule enzymes, required by the bacteria in the process of biosynthesis were selected as target molecules. five antibiotics benzylpenicillin, sulfadiazine, trimethoprim, rifampicin and ciprofloxacin, which are generally acknowle...

Listeria monocytogenes (Lm) is a bacterial pathogen that causes expensive food recalls, hospitalizations and even death. One of the key differences between Lm and other foodborne bacteria is that it thrives at typical refrigerator temperatures, about 4°C. In examining the effectiveness of an antimicrobial, most industry-standard bacterial testing is performed at 36°C (body temperature) which is...

The aim of this study was to determine the minimum inhibitory concentration (MIC) and antimicrobial effectiveness by the direct exposure test of 4 endodontic irrigants [1% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX), 1% calcium hydroxide (Ca(OH)2; prepared with 1 g of Ca(OH)2 and 100 mL of sterile distilled water), a solution of Ca(OH)2 + detergent (HCT20)] for S. aureus, E. faecalis, P...

BACKGROUND Stenotrophomonas maltophilia has emerged as an important nosocomial pathogen, capable of causing a wide spectrum of infections. Treatment is difficult because it is resistant to many antimicrobial agents, thus reducing the treatment options. The aims of this study were to describe the antimicrobial susceptibility patterns and synergistic effect of selected antimicrobial combinations ...

background: essential oils of medicinal plants such as chamomile are very complex natural mixtures which can contain compounds at quite different concentrations and some of their components have antioxidant and antimicrobial activities in foodstuff. objective: the antioxidant and antimicrobial effects of chamomile essential oil in cake preparation were evaluated during 75 days of storage. metho...

Antimicrobial capsules were evaluated for their effectiveness to control bacterial contamination of cool mist humidifiers. These capsules contain a mixture of silver and copper promoted alumina beads designed to release low concentrations of these oligodynamic metals into the reservoir water for bacteria control. The reservoir water and mist droplets from the humidifier units were tested for th...
