New species of antibiotic-resistant bacteria found in infected wound

(University of Gothenburg) A hitherto unknown antibiotic-resistant bacteria species, in the same family as E. coli and Salmonella spp., has been found and classified in Sweden. The proposed taxonomic name of the species -- the first of the new genus -- is Scandinavium goeteborgense, after the city of Gothenburg, Sweden, where the bacterium was isolated and the research was done.

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...

In this study, we examined the genome sequences of 2239 bacteriophages from different sources for the presence of ARGs. The identified ARG-carrying bacteriophages were then analyzed by PHACTS, PHAST, and HostPhinder programs to determine their lifestyles, genes coding for bacterial cell lysis, recombinases, and a spectrum of their potential host species, respectively. We employed the SplitsTree, RDP4 and SimPlot software packages in recombination tests to identify HGT events of ARGs between these bacteriophages and bacteria. In our analyses, some ARG-carrying bacteriophages exhibited temperate and/or polyvalent patterns. T...

Basamba Chicken litter application on land as an organic fertilizer is the cheapest and most environmentally safe method of disposing of the volume generated from the rapidly expanding poultry industry worldwide. However, little is known about the safety of chicken litter for land application and general release into the environment. Bridging this knowledge gap is crucial for maximizing the benefits of chicken litter as an organic fertilizer and mitigating negative impacts on human and environmental health. The key safety concerns of chicken litter are its contamination with pathogens, including bacteria, fungi, hel...

Natural microcin J25 (MccJ25) represent promising alternatives to traditional antibiotics for the treatment of drug-resistant infections. However, little is known about the antibacterial activity of recombinant MccJ25 against foodborne pathogens. Here, the activity of recombinant MccJ25 was examined using a matrix of conditions in order to assess the efficacy of recombinant MccJ25 as a mitigation against foodborne pathogens, Salmonella species and Escherichia coli (E. coli) O157. Results showed that recombinant MccJ25 displayed excellent antimicrobial activity against these foodborne pathogens, including clinical isolates ...

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...

ConclusionAltogether, our data suggested that loxapine might suppress intracellular bacteria through inhibiting of bacterial efflux pumps. In light of its unique activity, loxapine represents a promising lead compound with translational potential for the development of a new antibacterial agent against intracellular bacteria.
