Additional comments

• In this study, The genomic relatedness and spread of blaNDM-5 among Acinetobacter baumannii isolated from hospital surroundings and clinical specimens were studied. The paper is well written and commendable as It is the first report of an NDM-5-producing A. baumannii being found in hospital surroundings and clinical samples in Thailand.
• Title: the title needs to paraphrase for more clarity by referring to the region and the country from which these strains were isolated.
Abstract:
• The abstract offers an accurate summary of the paper, and the language used in the abstract is easy to read and understand.
• Line 48-49: Please rephrase the sentence for more clarity:
blaOXA-23 , blaNDM, and blaOXA-58 as (80.2%), (78.30%), and (0.94%), respectively.
• Line 50-51: Please rephrase the sentence for more clarity:
MDRAB and extremely drug-resistant A. baumannii (XDRAB) were found in 81.97% and 55.74%,
respectively.
• Keywords: Where are the keywords???

Introduction:
• Introduction: The authors provide sufficient context on the subject.
• Line 69, 70: The complete name of the abbreviation should be added just before its first mention only. especially multidrug resistant A. baumannii (MDRAB) and extensively drug- resistant A. baumannii (XDRAB) change as: especially MDRAB and XDRAB
• Line 82: Please mention the full name when it comes at the first time: New Delhi metallo-beta-lactamase (NDM).
• Line 97-98: please re write the sentence for more clarity: Whole-genome sequencing studies comparing distinct clinical isolates and environments isolates, change as: Whole-genome sequencing studies comparing distinct clinical and environmental isolates.
Materials and methods:
• Line 124 ,127: Please mention the Catalog number.
• Line 178-179: Please explain what the acronym CARD, VFDB stands for, you can add a paragraph with all the abbreviations used in your text.
• The authors did not refer to the statistical program used in this study, in addition to the fact that the statistic is very simple. A statistical analysis was supposed to compare these isolates for better clarity
Results: The findings are presented clearly, and the results are reliable.
• Lines 198-200: Please rephrase the sentence for more clarity, change as: The isolates associated with patient contact from the ventilator, bedsheet, patient table, humidifiers, ventilation, curtain, and, IV stand were (77.9%), (66.7%), (66.7%), (55.6%), (53.3%), (33.3%), (33.3%), (33.3%), (33.3%), and at 13.3%, respectively.
• Lines 201-203: Please rephrase the sentence for more clarity, change as: The isolates involved staff contact and other environments belonging to air, keyboard, counter, medical lab coats dressing, trolley, stethoscope, chart, door handles, and telephone at (60.0%), (53.3%), (46.7%), (42.9%), (33.3%), (26.7%), (26.7%), (6.7%), and (6.7%), respectively.
• Line 222-224: Please rephrase the sentence for more clarity, change as: MDRAB and XDRAB were found in 93.40%, and 44.34%, respectively. For A. baumannii from clinical samples, CRAB, XDRAB, MDRAB, and NRAB were found in 81.97%, 81.97%, 55.74%, and 16.39%, respectively (Table S3).
• The authors mention the terminology of isolates throughout the article, while it is more accurate to call them strains after their confirmation at the molecular level. The tables and figures are clear and comprehensible, however, abbreviations in tables should be indicated in the bottom margins of the tables
Discussion:
• When citing references, please consider the chronology from oldest to newest, some examples of this in the lines 356-357.
Conclusions: are clear, the study offers sample data for the authors to draw.
Grammar: Need some revisions along the manuscript.

Annotated reviews are not available for download in order to protect the identity of reviewers who chose to remain anonymous.

Basic reporting

This is porimarily a descriptive but interesting work related to the prevalence of A. baumannii in a hospital setting and partial pehotypic and genomic characterization of some isolates.
It is well written and structured, figures and tables are adequate and references are enough to support the information given.

Experimental design

the experimental design is adequate.

Please provide a rational for the selection of the 8 isolates that were sequenced and a figure showing the comparison of those genomes and a reference strain such as ATCC17978.

Validity of the findings

Data shown is OK, but please provide a rational for the selection of the 8 isolates that were sequenced and a figure showing the comparison of those genomes and a reference strain such as ATCC17978.

Additional comments

minor concerns:

L. 74-75 "The major mechanisms of carbapenem resistance mechanisms" remove the second "mechanisms"

L 148 "were performed using primers (Table S1)." change to "were performed using the primers shown in Table S1"

L. 200 "13.3%" use "()"

L 215 "A. Baumannii " use "b"

L. 222 "baumanniifrom"

Basic reporting

Current work is interesting due to provide information about one of the most critical microorganisms associated with healthcare infections.
However has several details associated with language, in order to this is recommended the revision with a fluent English speaker,
Some comments have made directly in document

Experimental design

About methods is highly recommended that authors to check susceptibility breakpoints and the use of the most recent lietarute or guide such as CLSI 2022
Colistin method is no recommended by kirby bauer, only with broth microdilution to stimate MIC.
In sequencing and enssamble, annotation associated to several genes is no proper, e.g some of them are associated to macrolides however they belongs to aminoglycosides, ADC is annotated such as carbapenemase however it is cephalosporinase. All genes must be corroborated.

Validity of the findings

Document has several technical errors however all of them can be fixed and improved
