(Please upload your review as an attachment if it exceeds 20,000 characters) Reviewer #1: Choe et al. report on an interesting study concerning a new blood culture bottle from Bioemerieux in the Bact/Alert series, which should speed up the detection of C. glabrata. The study is well presented, that data are appropriately related to the literature, and there is a good discussion and explanation on the weaknesses of the study, e.g., the inoculum used as compared to the clinical consiiton, and the use of horse blood instead of human blood. I have a couple of comments: 1. The aurhors need to review their statistical analysis of their data. From the CFUs reported in Table 2, it seems that the data may be skewed in direction of Poisson-distibutions - SD is larger than mean in several cases, and this also appears to be true for the TDD in Figure 1, where medians and and percentiles are shown. Here, data in Figure 2, the authors use T-tests for comparisons, which should instead be non-parametric tests such as the Mann-Whitney test. I wonder, whether the same counts for the CFU data in Table 2, CFUs are usually Poisson distributed. Also, since some of the NF-bottles were negative, again it is more correct to use medians and percentiles. It may not change the results but is more correct. 2. The hematocrit data for horse blood should be moved to the Results section. Reviewer #2: Mi-Kyung Lee presents a laboratory based study comparing the updated BacT/Alert blood culture bottles to the previous version of the bottle. Abstract: TTD is not written in full in the abstract. This should be done as readers will likely read the abstract prior to the full paper. Introduction: - Line 55- 56: what are the changes in the new bottle compared to the old bottle? Methods: - Suggest using the new names (based on taxonomic changes e.g. Nakaseomyces glabrata) - Table 1 - spelling error on "guilliermondii" - Why were clinical isolates included only for C.glabrata, not the other species Retrospective data analysis: were there any diagnostic or management differences between the 2 time periods which could have affected the TTD of the 2 bottles. Were the 2 periods collecting specimens from the same patient population? Results: - Line 150: how many of each species was included in each period? Overall were there a similar number of isolates in both periods? - greater variability in TTD as per figure 1. These findings are inconsistent with the conclusion of the paper which suggests that the newer bottle performs better. It only performed better for 1 species. Line 155: "For the other 3 species...there was no significant difference" This statement is incorrect. For C.parapsilosis, TTD was much longer with the new bottle (p= 0.05)...which is bordering on a significant difference. Discussion: - line 181: spelling error again on C.guilliermondii - Line 188 - Suggest reword to "Although C.auris is resistant to multiple antifungal agents" - line 189 - blood infections should be bloodstream infections Additional Limitations: - only including ATCC strains for the majority of species and including clinical isolates only for C.glabrata - comparing retrospective clinical data over 2 separate time periods Reviewer #3: Dear Authors, In your study, in which you compared the reproduction times of Candida species in your study, it does not include any information or discussion about the blood culture system, except for the time period. In order for your study to have a scientific result, you should reveal the differences in the old and new blood culture bottles, and the issues that can be developed technically or that are recommended to be developed should be expressed. The scientific contribution of the study in this state is very limited. The introduction, material, method and discussion parts of the study contain insufficient or inappropriate information. The work in its current form is unacceptable to me. Best regards Reviewer #4: Thanks for your invitation to review the manuscript entitled” Comparison of New and Old BacT/Alert Aerobic Bottles for Detection of Candida spp”. according to my opinion, the number of samples in this study is low, and new and important methods are not used. It is better to publish this manuscript after revision as a report or a short article. Comments: - Please don’t use abbreviate words in the Title and Abstract. - In this sentence” The overall and clinical samples of C. glabrata showed similar results. C. albicans (27.6 versus 25.1 hours; P < 0.001) and C. guilliermondii (28.8 versus 27.3 hours; P = 0.026) also showed significantly shorter TTDs between the Old and New FA Plus bottles”. The P value calculation is not correct because there is no significant difference between the presented numbers. Reviewer #5: Concerns; 1. For the abstract, please ensure full meanings of words/expressions are written for the first time and then subsequently, abbreviations could be used. 2. Line 53 "It has been reported that C. glabrata was more affected by the blood culture system and medium than C. albicans" this statement is vague, please clarify, affected in what way. 3. The methods/materials should start by stating clearly what study design this research employed and the study settings. This will help readers to understand the study concept from the start. 4. Without going deep into proprietary issues, the authors should at least describe in basic terms what difference there is among the culture media employed. 5. The conclusion does not bring out the full picture of this study. The absence of significant difference in the other Candida species between the new and old media should at least be acknowledged and then the major finding of interest (i.e C. glabrata) and its importance highlighted. 6. Also, the authors should have explained in the methods or discussion what the new FA Plus bottle differentially has to make this conclusion "This study shows that the TTD of C. glabrata was markedly reduced in the New FA Plus bottle due to the optimized growth performance". Otherwise, "due to the optimized growth performance" could not be concluded from the findings in this study. ********** 6.
