Reviewer ’s report  
 
Title: Prevalence of Mycoplasma genitalium Infection in Women with Bacterial Vaginosis.  
 
Version: 1 Date: 15 Feb 2020  
 
Reviewer: Dai Zhang  
 
Reviewer's report:  
The author did not understand my last suggestion, and the revised content should be as follows: 
First, there is no change in the diagnostic criteria for BV on page 5. A lthough there are other 
articles that use the AMSEL criteria to correct the Nugent score when diagnosing BV, for this 
study. I recommend authors to use cases that meet both AMSEL criteria and NUGENT score 7 -
10 criteria as confirmed BV patients;Second, the following data can be seen in Table 1.  
BV                      Positive (563) 33 (5.9%)  Negative (969) 29 (3.0%)  
Amsel Criteria      Positive (464) 22 (5.0%)  Negative (1068) 40 (3.7%)  
Nugent Score       Positive (469) 27 (5.8%)  Negative (1063) 35 (3.3 %)  
I think the final number of BV cases should not be higher than the number diagnosed by AMSEL 
or Nugent alone.  
If authors cannot diagnose BV using the above strict criteria due to some difficulties, please state 
in the article.  
Please  modify the articl e seriously.
