Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your research work to this Special Issue, “New insights into the antibiotic resistance of aquatic microorganisms”, in the Microorganisms section “Antimicrobial Agents and Resistance”.

Natural environments are considered important reservoirs of antibiotics and antibiotic resistance genes (ARGs), which may be relevant for the emergence and dissemination of antibiotic resistance among pathogenic and environmental bacteria. Horizontal gene transfer has a crucial role in the spread of ARGs, as these may be located in mobile genetic units. Increasing attention has been given to aquatic environments, with new perspectives being explored, such as the study of cyanobacteria as new players in the freshwater resistome or the role of mollusk pathogenic and commensal bacteria in the aquaculture resistome. Antibiotics resistance is currently approached from the One Health perspective; however, the environmental resistome is far from being fully understood.

This Special Issue aims to gather original research articles and reviews that allow us to better understand the role of aquatic microorganisms in the environmental resistome. All contributions within this discussed scope are welcome. We are particularly interested in papers with new research perspectives regarding antibiotic resistance in native and commensal and pathogenic bacteria from water environments.

Research areas may include (but are not limited to) the following:

  • Antibiotic resistance phenotype and genotype of microorganisms from aquatic environments (freshwater, seawater, aquaculture, wastewaters).
  • Factors contributing to antibiotic resistance in aquatic environments, such as antibiotic residues.
  • Antibiotic resistance in water environments vs. the One Health approach.

We look forward to receiving your contributions.

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 submissions that pass pre-check are 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. Microorganisms 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 2700 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.

Vibrio parahaemolyticus, commonly found in seafood products, is responsible for gastroenteritis resulting from the consumption of undercooked seafood. Hence, there is a need to characterize and quantify the risk involved from this pathogen. However, there has been no study reporting the quantification of hemolytic antimicrobial-resistant (AMR) Vibrio parahaemolyticus in locally farmed shellfish in Singapore. In this study, ampicillin, penicillin G, tetracycline resistant, and non-AMR hemolytic V. parahaemolyticus were surveyed and quantified in green mussel samples from different premises in the food chain (farm and retail). The occurrence data showed that 31/45 (68.9%) of farmed green mussel samples, 6/6 (100%) farm water samples, and 41/45 (91.1%) retail shellfish samples detected the presence of hemolytic V. parahaemolyticus. V. parahaemolyticus counts ranged from 1.6–5.9 Log CFU/g in the retail shellfish samples and 1.0–2.9 Log CFU/g in the farm water samples. AMR risk assessments (ARRA), specifically for ampicillin, penicillin G, tetracycline, and hemolytic (non-AMR) scenarios were conducted for the full farm-to-home and partial retail-to-home chains. The hemolytic ARRA scenario estimated an average probability of illness of 5.7 × 10−3 and 1.2 × 10−2 per serving for the full and partial chains, respectively, translating to 165 and 355 annual cases per total population or 2.9 and 6.2 cases per 100,000 population, respectively. The average probability of illness per year ratios for the three ARRAs to the hemolytic ARRA were 0.82, 0.81, and 0.47 (ampicillin, penicillin G, and tetracycline, respectively) for the full chain and 0.54, 0.39, and 0.09 (ampicillin, penicillin G, and tetracycline, respectively) for the partial chain. The sensitivity analysis showed that the overall cooking effect, initial concentrations of pathogenic V. parahaemolyticus, and harvest duration and harvest temperature were key variables influencing the risk estimates in all of the modelled ARRAs. The study findings can be used by relevant stakeholders to make informed decisions for risk management that improve food safety. Full article
