Review:  
 
Dr. Achilli et al. describe in this case report an interesting and unique complication of invasive 
Streptococcus Agalactiae (GBS) in a healthy man who presented with massive splenic infarct 
and right hepatic artery mycotic aneurysms.  
 
The authors present a dequately the evolution of the case, including its presentation, initial 
diagnosis, management, and hospital course. They also elaborate at length on certain aspects of 
invasive GBS disease including a review of infective endocarditis, splenic infarction, and 
mycotic aneurysms.  
 
Some aspects of the manuscript deserve more attention, including the following:  
 
Please condense the case presentation and the discussion. For the discussion, I would suggest 
focusing on the presentation, differential diagnosis, a nd management of hepatic artery mycotic 
aneurysms. The management of infective endocarditis is not novel, and is extensively published.  
 
Please change the abbreviation for Streptococcus Agalactiae to GBS, for Group B Streptococcus. 
The abbreviation SA ref ers more commonly to Staphylococcus Aureus.  
 
Please revise the use of the word "extended" in line 83. Did you mean "extensive"?  
 
Please revise the sentence formulation throughout the manuscript, but especially in the 
discussion (eg. Line133, 135 etc…).  
 
Please revise the liver segment denomination throughout the manuscript (eg. In Line 117, it 
should read "segment VIII" and not "VIII segment").  
 
Please revise the use of abbreviations throughout the manuscript (eg. Line 138).  
 
Please use the same abbreviat ions consistently (eg. "day" compared to "die" in Line80 and 90).   
 
Please revise the use of punctuation throughout the manuscript.
