Special Issue Information

Dear Colleagues,

We are pleased to invite the attendees of the Biotech 2020 Symposium to submit a review or original research article to the Special IssueA Selection of Studies Presented at Biotech 2020 Symposium” of the journal Antibiotics (MDPI, ISSN 2079-6382, impact factor 2.921), with Prof. Dr. Flavia Marinelli from University of Insubria, Italy, serving as the Guest Editor. Antibiotics is an international, open access journal of scientific studies related to all aspects of antibiotics, including pharmacodynamics, uses of antibiotics, antibiotic resistance, and antimicrobial stewardship. Antibiotics is rigorously peer reviewed and edited, producing high-quality and rapid publications. Papers accepted after peer review will be published immediately online after author proofreading and processing.

The symposium participants who are interested to publish papers to this Special Issue are requested to send a tentative title and a short abstract of the intended contribution to Ms. Monica He ([email protected]), the Editor of Antibiotics. Please refer to the instructions for authors when preparing your manuscript. Submission deadline: August 31, 2021.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Antibiotics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Arrayan and peumo fruits are commonly used in the traditional medicine of Chile. In this study, the concentration of the extracts halving the bacterial viability and biofilms formation and disruption of the drug-sensitive and drug-resistant strains of Staphylococcus aureus and Pseudomonas aeruginosa was determined. The chemical composition of extracts was analyzed by high-resolution liquid chromatography coupled with mass spectrometry (U-HPLC/MS). The arrayan extract (Inhibitory concentration IC50 0.35 ± 0.01 mg/mL) was more effective than peumo extract (IC50 0.53 ± 0.02 mg/mL) in the inhibition of S. aureus planktonic cells. Similarly, the arrayan extract was more effective in inhibiting the adhesion (S. aureus IC50 0.23 ± 0.02 mg/mL, P. aeruginosa IC50 0.29 ± 0.02 mg/mL) than peumo extracts (S. aureus IC50 0.47 ± 0.03 mg/mL, P. aeruginosa IC50 0.35 ± 0.01 mg/mL). Both extracts inhibited quorum sensing in a concentration-dependent manner, and the most significant was the autoinducer-2 type communication inhibition by arrayan extract. Both extracts also disrupted preformed biofilm of P. aeruginosa (arrayan IC50 0.56 ± 0.04 mg/mL, peumo IC50 0.59 ± 0.04 mg/mL). However, neither arrayan nor peumo extracts disrupted S. aureus mature biofilm. U-HPLC/MS showed that both fruit extracts mainly possessed quercetin compounds; the peumo fruit extract also contained phenolic acids and phenylpropanoids. Our results suggested that both extracts could be used as natural antimicrobials for some skin and nosocomial infections. Full article
