Toxoplasma gondii Seropositivity and Co-Infection with TORCH Complex Pathogens in Pregnant Women from Araçatuba, Brazil
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThank you for the opportunity to review this manuscript.
Abstract: please write “T. gondii” in Italic throughout the manuscript.
Introduction: I would personally add a paragraph on serology for the diagnosis of acute/chronic toxoplasmosis.
Materials and methods: “2.5 Análise laboratorial” does not sound English to me ☹
Please add the assay and the reagent for all the laboratory tests included in the study.
Results:
Line 154: “suggesting recent infection” I would delete this statement without an additional IgA antibody against T. gondii test and an IgG avidity test.
Please see: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4609698/
I don’t see anywhere in the manuscript a comparison between urban and rural areas, since T. gondii seropositivity is linked to rural areas, and you know the location of each health unit, please include this comparison as well. Or, if for some reason you don’t want to do it, maybe due to the overrepresentation of the urban regions, mention it in the newly limitation section 😊.
Discussion:
Please add the study limitations; maybe not determining IgA against T. gondii and IgG avidity in IgM positive females could be considered one.
Line 245: “acute infection (IgM) in pregnant women was diagnosed in 20 (6.7%) cases during 245 the first trimester of gestational age by detecting IgM antibodies.” I advise EXTREME caution when diagnosing acute toxoplasmosis solely on IgM antibodies. PLEASE, research the role of IgA antibodies against T. gondii and IgG avidity in the diagnosis of acute toxoplasmosis and rephrase this paragraph.
Author contributions, funding, data availability, conflict of interest, author contributions: please revise, no need to let the MDPI guidelines or the “ “ in there ….
I consider this article to be important for the field and should be considered for publication if the authors consider fixing the issues i've pointed out, especially the diagnosis of acute toxoplasmosis.
Wishing you the best,
Reviewer
Comments on the Quality of English LanguageThey need to re-check the manuscript and remove some mdpi guidelines and also, translate some spanish i guess, into english. Besides that, nothing to add. English is clear to me.

Or, if for some reason you don’t want to do it, maybe due to the overrepresentation of the urban regions, mention it in the newly limitation section ?.
Response 6: We acknowledge the overrepresentation of urban regions in our study, with only one health unit located in a rural area. Given this imbalance, a direct comparison between urban and rural areas regarding T. gondii seropositivity may not yield Statistically meaningful results. Therefore, we have chosen not to perform this analysis. This limitation has been addressed in the newly added in manuscript (Data Analysis). Thank you.

Discussion:
Please add the study limitations; maybe not determining IgA against T. gondii and IgG avidity in IgM positive females could be considered one.
Response 7: As suggested, the absence of IgA determination against T. gondii and the lack of IgG avidity testing in IgM-positive females have been recognized as limitations of this study and have been included. Thank you.

Reviewer 2 Report
Comments and Suggestions for AuthorsOverall, the manuscript presents valuable research on the seropositivity of Toxoplasma gondii and co-infection with TORCH complex pathogens among pregnant women in Araçatuba, Brazil. The study's findings are significant and contribute to public health knowledge, particularly in areas of prenatal care and congenital infections. However, a few minor revisions are necessary to enhance the clarity and comprehensiveness of the manuscript:
Line 29: It is recommended to add more relevant keywords to improve the manuscript's visibility and accessibility.
Lines 56-57: The discussion on the prevalence of toxoplasmosis would benefit from the inclusion of additional studies, especially high-quality meta-analyses, to provide a more robust background. Additionally, more local prevalence and incidence data should be included, particularly for the area where the study was conducted.
Line 86: The term "on1" requires clarification to ensure readers understand its context and meaning.
Line 106: Ensure that the language used throughout the manuscript is consistent with standard English usage.
Furthermore, it is essential to mention the criteria that were followed to conduct the study and provide details on the anonymization methods used to protect participants' identities.
