Authors: Reissier S, Cattoir V Abstract INTRODUCTION: Streptogramins (pristinamycin and quinupristin-dalfopristin) can be interesting options for the treatment of infections due to Gram-positive cocci, especially multidrug-resistant isolates. AREAS COVERED: This review provides an updated overview on structural and activity characteristics, mechanisms of action and resistance, pharmacokinetic/pharmacodynamic and clinical use of streptogramins. EXPERT OPINION: The streptogramin antibiotics act by inhibition of the bacterial protein synthesis. They are composed of two chemically distinct compounds, namely typ...

Authors: Phuyal N, Jha PK, Raturi PP, Rajbhandary S Abstract Crude methanol extracts of fruits, seeds, and bark of Zanthoxylum armatum were investigated in vitro for antimicrobial activities against 9 different bacterial strains: Bacillus subtilis, Enterococcus faecalis, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhi, Shigella dysenteriae, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus (MRSA), and Staphylococcus epidermidis using agar well diffusion method, and the MBC values were determined. Only 5 bacteria, i.e., Bacillus subtilis, Enterococcus faecalis, MRSA, Staphylococcus aureus...

Publication date: 1 March 2020Source: Materials Chemistry and Physics, Volume 243Author(s): Samir Bouchareb, Rachida Doufnoune, Farid Riahi, Hafsa Cherif-Silini, Lassaad BelbahriAbstractGO-Ag nanohybrids have attracted tremendous attention thanks to their several potential properties. In this research work, a new approach was adopted, where Triphenylphosphine (PPh3) was used as a linkage to decorate the surface of Graphene oxide (GO) nanosheets by Silver nanoparticles (AgNPs) via a simple method. The Fourier transform infrared spectroscopy (FTIR), Ultraviolet–visible spectroscopy (UV–Vis), X-ray diffraction ana...

The goal of this study was to isolate, screen, and characterize Arctic microbial isolates from Expedition Fjord, Axel Heiberg Island, Nunavut, Canada capable of inhibiting the growth of foodborne and clinically relevant pathogens. Arctic bacteria were isolated from twelve different high Arctic habitats pertaining to active layer permafrost soil, saline spring sediments, lake sediments, and endoliths. This was achieved using (1) the cryo-iPlate, an innovative in situ cultivation device within active layer permafrost soil and (2) bulk plating of Arctic samples by undergraduate students that applied standard culturing. To mit...

Conclusions/implications While bismuth subsalicylate, and bismuth tribromophenate unbound to Xeroform® demonstrate antimicrobial activity, it appears that Xeroform® dressings do not. The utility of Xeroform® in burn medicine may relate more to use as an impervious dressing than to antimicrobial effect. Donor sites are clean surgical wounds and clean partial thickness burns may have minimal colonization present. In such circumstances, an inactive and impervious dressing may be all that is necessary to promote wound healing. Graphical abstract

Publication date: 15 September 2017 Source:LWT - Food Science and Technology, Volume 83 Author(s): Surya Kant Verma, Shiv Kumar Sood, Ram Krishan Saini, Neha Saini The present study was carried out to enhance shelf life of raw buffalo milk by the use of pediocin PA-1 containing fermented cheese whey (PCFCW) as bio-preservative. Ten distinct genera of milk microbes could be identified as Streptococcus, Enterococcus, Salmonella, Campylobacter, Lactobacillus, Enterobacter, E. coli, Shigella, Candida and Aspergillus. For the production of PCFCW, supplemented cheese whey medium was fermented with Pediococcus pentosaceous NCDC ...

The World Health Organization is issuing a warning about a group of deadly bacteria: Recently, the WHO released its first-ever list of “priority pathogens,” a list of antibiotic-resistant bacteria that the organization says pose the greatest threat to human health. The list is divided into three categories: critical-, high- and medium-priority. Three pathogens made it into the critical-priority group. These bacteria are resistant to multiple antibiotics and pose a high risk to people in hospitals and nursing homes, the WHO says. Multidrug-resistant bacteria, sometimes called “superbugs,” are a ...

ConclusionPKS gene expression indicated β keto‐acyl synthase as one of the important active domains in the biomolecules related to antitumour and antifungal group. The simultaneous identification of the biomolecule (dihydro‐2H‐pyran‐2‐one derivative) was also inferred spectroscopically. Significance and impact of the studyFreshwater cyanobacteria are the prolific producers of secondary metabolite(s) that may act as the antimicrobial drug resource in addition to their much explored marine counterpart.This article is protected by copyright.
