Industrialization as a Factor Enhancing Antibiotic Resistance in Wastewater, Sewage Sludge and River Water

PLOS ONE

Dear Dr. Harnisz,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

There are a number of areas for improvement identified by the reviewer. In addition, it is very important to differentiate correlation and causation and some of the observed correlation should not be explained as the cause of the observed resistance unless the mechanisms were directly examined. The revised manuscript must be thoroughly revised and all presumptive conclusions (e.g. heavy metals exert a permanent influence or HMs promoting drug resistance) need to be based on experimental data and detailed mechanistic discussions should be included.

Please submit your revised manuscript by May 08 2021 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

  • A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: http://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols

We look forward to receiving your revised manuscript.

Kind regards,

Zhi Zhou, Ph.D.

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

**********

4. Is the manuscript presented in an intelligible fashion and written in standard English?

Reviewer #1: Please correct some minor errors specifically in the Materials and Methods section. Include the supplier and country information for all reagents and consumables used in the experimental procedures. Include the model and manufacturer information for all equipment used. Include the %/concentrations of all reagents used. This information should be included each time. The HM data should be discussed and compared with the acceptable guidelines of the country and it needs to be indicated if it comply.

Revision 1

We would like to thank the Editor and Reviewer for detailed and helpful suggestions which have been taken into consideration in the revision process. Our responses to specific comments are presented below. The introduced changes and grammatical revisions have been highlighted in yellow in the manuscript.

Response to Editor suggestions

Comment: “There are a number of areas for improvement identified by the reviewer. In addition, it is very important to differentiate correlation and causation and some of the observed correlation should not be explained as the cause of the observed resistance unless the mechanisms were directly examined. The revised manuscript must be thoroughly revised and all presumptive conclusions (e.g. heavy metals exert a permanent influence or HMs promoting drug resistance) need to be based on experimental data and detailed mechanistic discussions should be included.”

We are glad of the comment, we have revised the manuscript and have made corrections. We have changed the sentences to avoid drawing straight conclusions based on the presented correlations, in “Impact of industrialization on antibiotic resistance - correlation analysis” subsection and “Conclusions” section, lines 615, 617-619, 643 and 647.

Response to Reviewer suggestions

General revision

We provided improvements through the manuscript body as reviewer requested:

- we have included suppliers information and details about reagents and consumables,

- we have included model and manufacturer information of all equipment,

- as suggested we have added significant literature,

- as suggested we have included grammatical revision

All introduced to the manuscript changes are highlighted in yellow.

L2: Not all words in capital letters; Title does not include heavy metals

We have changed the title to “Industrialization as a source of heavy metals and antibiotics which can enhance the antibiotic resistance in wastewater, sewage sludge and river water”.

L27: Revise the aim to prevent repetition

Thank you very much for your suggestion, however, it is difficult for us to understand it and implement significant changes. We do not find in this section the repetitions indicated in the comment.

L33: Copy numbers?

Yes. We added “copy numbers” to clarify this sentence.

L36: Please clarify - was the concentration of the different antibiotics determined as well as the presence of specific resistance genes against these antibiotics which were then correlated?

To clarify the issue we have added to the sentence “that corresponded to genes encoding resistance” (L35).

L35: Clarify? or Classes?

We have changed to “classes” (L36).

L35: Please clarify and provide an exact value. L37: Please clarify - based on what is this assumption made?

Regarding to two comments, we have created changes in two sentences, explaining on what is this assumption made (L36-38).

L86: Provide values

As suggested we have added the values based on the references (L87-89).

L97: What about antibiotics? Reduce bacterial load but not resistance genes as such.

We have added the information about removal of pharmaceuticals from wastewater during treatment process (L99-102).

L130: Revise not the correct word

We have revised the mistaken word and changed it (L134).

L201: Include a complete descriptive heading for the table

We have changed the table title to be more descriptive and added an expansion for abbreviations (L200-202).

L354: Please include how this compare with acceptable levels indicated in guidelines

As suggested we have added the comparison to acceptable levels regulated by Minister of Environment in Poland (L385-391).

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
