Dear Dr. Haque,

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.

Please submit your revised manuscript by Jan 23 2026 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: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols.

We look forward to receiving your revised manuscript.

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. -->

Reviewer #1: No

Reviewer #2: Yes

-->2. Has the statistical analysis been performed appropriately and rigorously? -->

Reviewer #1: No

Reviewer #2: Yes

-->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: No

Reviewer #2: Yes

**********

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

PLOS ONE does not copyedit accepted manuscripts, so the language in submitted articles must be clear, correct, and unambiguous. Any typographical or grammatical errors should be corrected at revision, so please note any specific errors here.-->

Reviewer #1: No

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)-->

Reviewer #1: The authors conducted this study to determine the presence and antimicrobial resistance profiles of various Gram-positive and Gram-negative bacteria isolated from local electrolytes in Bangladesh. This study seems interesting, but I found a lot of serious drawbacks! I believe the authors should check the CLSI guidelines properly before selecting antibiotics against different bacteria. Moreover, I found some serious issues in the AMR results. For example, Klebsiella pneumoniae is intrinsically resistant to ampicillin, amoxicillin, amoxicillin-clavulanic acid, and cefoxitin, but they found 30.77%, 19.23%, 3.85%, and 15.38% of the isolates, respectively. This result doesn’t make sense. The same happened to Pseudomonas aeruginosa, Acinetobacter baumannii, and others. Moreover, you mustn’t follow CLSI 2018 for Vibrio isolates; you should follow CLSI 2015. Also, you used the disk diffusion test for vancomycin, but you mustn’t do that. You must determine MIC values for Staphylococcus aureus against vancomycin to determine their resistance profiles. Overall, I feel the authors didn’t conduct the study properly. They should repeat the study with a proper study design and antimicrobial agent selection. They should also properly evaluate the lab work and results to maintain scientific integrity.

Reviewer #2: The article describe the "Microbiological quality assessment of potential pathogenic bacteria and multidrug

resistance patterns in commercial electrolyte drinks in Dhaka, Bangladesh". The article is well written with sufficient data and the results are convincing. However, the author should consider the following points before finalizing the manuscript.

1. The author isolated a number of bacteria from different samples. the author should add the images of grams staining as well as the characteristic colony of the isolated bacteria in the supplementary materials.

2. It would be good to to show Antimicrobial Resistance (AMR) using heat maps, and this is a widely used and effective method in scientific research and public health surveillance. Heat maps provide a clear visual representation of complex AMR data, allowing researchers and public health officials to identify patterns, trends, and correlations easily.

3. Discuss the production volume and popularity of electrolyte drink in Bangladesh in the introduction section of the manuscript.

4. The authors identified antibiotic resistance only phenotypically, the authors can target known genes responsible for that resistance mechanism.

For Methicillin-resistant Staphylococcus aureus (MRSA): The primary target is the mecA or mecC gene, which encodes penicillin-binding protein 2a (PBP2a), conferring resistance to methicillin and most beta-lactams.

For Extended-Spectrum Beta-Lactamase (ESBL) producers (common in E. coli and Klebsiella): Common genes to screen for include blaCTX-M, blaTEM, and blaSHV subclasses.

For Carbapenem-resistant Gram-negative bacteria: Key carbapenemase genes include blaKPC, blaNDM, blaVIM, blaIMP, and blaOXA-48-like.

For Tetracycline resistance: Common genes are tetA, tetB, tetM, etc.

Data regarding the resistance mechanism will improve the quality of the manuscripts and would be more acceptable to the readers.

As the corresponding author, your ORCID iD is verified in the submission system and will appear in the published article. PLOS supports the use of ORCID, and we encourage all coauthors to register for an ORCID iD and use it as well. Please encourage your coauthors to verify their ORCID iD within the submission system before final acceptance, as unverified ORCID iDs will not appear in the published article. Only the individual author can complete the verification step; PLOS staff cannot verify ORCID iDs on behalf of authors.

We look forward to receiving your revised manuscript.
