Background Bloodstream infections are common acute syndromes of variable origin with high chances for extreme health effects including death. This underscores the essence for their quick management to expedite better outcomes. In this study settings, therapy is predominantly empirical using majorly cefriaxone and/or metronindazole. Agents for empirical therapy are liable to antimicrobial resistance and their choice ought to be routinely guided by microbiology laboratory data. This study determined the most frequent aetiologic agents responsible for bloodstream infections, their antimicrobial susceptibility patterns, and infection sources in Eastern-central Uganda. Patients and methods: The analysis involved all non-duplicate blood culture reports from 2019 to 2021 using World Health Organization Network (WHONET) 2022 desktop software and Microsoft Excel. Results: The 1364 reports showed a diagnostic yield of 114(6.8%) and a 1.5% contamination rate. Over 37% and 13% of infections were hospital-acquired and community-acquired respectively. Most etiologic agents were Gram-positive bacteria dominated by Staphylococcus aureus 39(34.2%). Polymicrobial growth existed in 4(0.3%) cases. S. aureus was mainly resistant to penicillin G(100%) but most susceptible to gentamicin(%S=74.1, 95%C.I:53.4-88.1). Escherichia coli and unspecified Coliforms together showed high resistance to ampicillin(87.5%) and third-generation cephalosporins(100%). The least resistance was to chloramphenicol and carbapenems. Conclusion: As the most frequent explanatory for septicaemia, S. aureus suspected cases in this region could have higher success with gentamicin involved in the empirical therapy combination for their management. The heightened resistance against ceftriaxone requires its limited use. Microbiology services should be routinely utilized to guide targeted antimicrobial use, monitor blood culture contamination rates and resistance trends to strengthen regional antimicrobial stewardship.

Comments to Author
In conclusion, paper suggested empirical treatment based on cumulative data of hospital and community acquired isolates. The resistance pattern of hospital and community acquired BSIs is quite different. In Conclusion section, it is suggested to add a recommendation of monitoring both hospital and community acquired resistance pattern to strengthen antimicrobial stewardship and surveillance policies.

Comments to Author
An interesting epidemiologic study carried out in one of limited-resources countries. However, several issues are raised for authors to be addressed carefully. -What exactly the study type? Authors mentioned that it is a retrospective study, but this is not sufficient. Besides, what are the guidelines used by authors to ensure transparency and validity of their work. -Introduction seems to be too long. It should be shortened to be concise and informative. -Authors used 48 hs-admission as definition of hospital acquired infection. This is inaccurate. Indeed, this is the definition of nosocomial infection, while hospital-acquired infection has another more specific definition. Please see CDC definitions available at CDC website. -Authors did not mention how are blood samples collected? how many bl. …

Authors mentioned that it is a retrospective study, but this is not sufficient.

Indeed, this is the definition of nosocomial infection, while hospital-acquired infection has another more specific definition. Please see CDC definitions available at CDC website. -Authors did not mention how are blood samples collected? how many bl. culture sets were collected from each patient. It seems crucial as authors define CoNS positivity was excluded as contaminant!! This is unclear and inaccurate. CoNS might be contaminant, but also have been implicated as true pathogens in BSIs. -Authors used many antibiotics in disc diffusion method. What is the value of using chloramphenicol. They used tetracycline while this antibiotic is not included in CLSI guidelines. Authors should revise carefully their antibiotics pannel. -Authors used WHONET software program supported by WHO for microbiological, epidemiological and IC surveillance activities. However, authors did not use this excellent program professionally. The program provide many tools as %R, isolate listing, cross-resistance, predicting outbreaks, flagging unusual pathogens, usual pathogen with unusual antibiogram, etc. Authors should present more detailed findings as per WHONET tools. -Authors mentioned lack of many clinical/demographic data during analyisis as one of the limitation. I think this is a major flaw in the work. Research studies for epidemiologic purpose and while using WHONET, all details should be included. Please jsutify. -Identification of MRSA based on cefoxitin-resistance is insufficient as per CLSI guidelines. Authors should revised the criteria used to identify MRSA. -In table 1: What is the meaning of significant growth? how authors judge significance. Also, who authors define contaminants. It seems very important to be defined clearly.

Do you have any concerns of possible image manipulation, plagiarism or any other unethical practices?
Yes: The study is lacking Approval/consent by Ethics or Research Committee or Institution Review Board (IRB). Besides, the study is lacking the study design checklist for its type. For author, please, revise the Equator.org website to specify your study type and what is the suitable study type guidelines for your work. Finally, the study should declare that it was conducted as per Helsinki declaration

Many thanks for the author for his interesting piece of work. Understanding antimicrobial resistance trends are indeed vital in influencing empiric antimicrobial prescribing guidelines. I do think your manuscript is of value but am issuing an early Major Revise as I do think it can be polished before inviting reviewers. As it stands, I do believe reviewers would have a hard time agreeing to review. Your abstract needs to be revised, it is what reviewers read first before agreeing to review. At the moment your data needs to be presented more impactful. You have collected so much interesting data but the abstract does not effectively reflect this. I think it would be useful to preface what are usually used for treatment and then highlight the resistance rates to show how your review has direct implications on patient care. The rest of …
Many thanks for the author for his interesting piece of work. Understanding antimicrobial resistance trends are indeed vital in influencing empiric antimicrobial prescribing guidelines. I do think your manuscript is of value but am issuing an early Major Revise as I do think it can be polished before inviting reviewers. As it stands, I do believe reviewers would have a hard time agreeing to review. Your abstract needs to be revised, it is what reviewers read first before agreeing to review. At the moment your data needs to be presented more impactful. You have collected so much interesting data but the abstract does not effectively reflect this. I think it would be useful to preface what are usually used for treatment and then highlight the resistance rates to show how your review has direct implications on patient care. The rest of the manuscript needs to be thoroughly reviewed for grammatical errors throughout, especially in terms of capitalization and italicization. The Introduction can also be significantly condensed, as well as the Discussion. Your Conclusion is important, but it does not connect your data with what is being used in real-world Uganda. Do they have empiric antimicrobial prescribing guidelines? How do these connect with your findings. The Results could be made clearer, double-check your Figures especially for titles and axes. I would highly recommend you to revise your manuscript and resubmit as it is a great piece of work that just requires a few changes.
