Effect of Relocation, Social Housing Changes, and Diarrhea Status on Microbiome Composition of Juvenile Cynomolgus Macaques (Macaca fascicularis)
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsLine 60-72 are considered to be informations for Materials and methods. Please formulate a specific aim of the study and move the lines 60-72 to the subchapter Materials and Methods. In this form of the manuscript the aim of the study is missing.
Add more details about the animals' diet. Did they receive the same diet from the beginning? During and after the quarantine period? Were there any signs of diarrhea related to the diet? What is the chemical composition of the diet? The nutrient content can influence intestinal transit and the composition of the microbiota.
The results could be explained in more details.
Line 406-407 - mention the sex/gender that presented differences.
Add some new references from 2023-2024
The ideea of the study is very interesting but the final results does not reveale new findings.

Comments and Suggestions for AuthorsManuscript microorganisms-3344176, entitled “Effect of Relocation, Social Housing Changes and Diarrhea Status on the Microbiome Composition of Juvenile Cynomolgus Macaques (Macaca Fascicularis)”
Recommendation: The above paper is not suitable for publication in its present form.
This article provides information on the effect of relocation, social housing changes and diarrhea status on the microbiome composition of juvenile Cynomolgus Macaques (Macaca Fascicularis). It is in general appropriately organized, carried out and written, however there are some points that should be corrected or clarified.
L9: “…can be associated with…”
L11: “reported” instead of “characterized”
L27-28: “problems” instead of “conditions”
L45: “[11-13]” instead of “[11,12] [13]”
L65-66: What do you mean by “enough samples”?
L82: “evaluated for culture”?
L106: “observed” instead of “seen”
Figure 2: Are these differences significant? P-values?
L152: “…would be associated with…”
L157: “found” instead of “seen”
L178-179: This is not clear in Figure 3
L180: “observed” instead of “seen”
L206: “shown” instead of “noted”
L207: Please delete the second “in”
L236: “Furthermore”
L239: “Finally” instead of “Further”
L247: As shown in Table 1, it is difficult the mean age to be 2.91!
L269-270: Please rephrase
L276: “observed” instead of “seen”
L295: “which animals would break with diarrhea”?
L346: “carried out” instead of “done”
L354-358: This part should be removed to “4.7. Data analysis”
L411: “inform future studies”?
