Round 1

Reviewer 1 Report

This review manuscript by Hernández and Vives entitled “Phages in anaerobic systems” provides an extensive insights on bacteriophages active on obligate anaerobes and discusses how anaerobiosis can be an important parameter in phage infection, especially among facultative anaerobes.

I appreciate the authors clarity of the manuscript, organization of the paper and figures. There are only a couple minor spelling mistakes.

 

Line 339: change UFP to PFU

Figure 2: change Comparation (on the column) to Comparsion

Author Response

Dear Reviewer,

We thank you for the comments and help to improve the manuscript.

Accordingly, we changed:

  • typo in name of Dr. Symour Benzer in line 56.
  • verb have was changed for has in line 116.
  • line 339 (now line 346) UFP to PFU.
  • Archea for Archaea in line 354.
  • figure 2, Comparation for Comparison.
  • Typos in the reference section.

Best regards,

Santiago Hernández and Martha Vives

Reviewer 2 Report

The authors presented a comprehensive review. It would be great if they could:

  1. Shorten the text, as some of the general historical background information redundantly appeared in several places.
  2. Give sufficient references in several places, such as lines 47- 74, 76-79, 93-95, 111-112, 275-277.
  3. Check the typos, such as line 57, Dr. Seymour Benzer's name was misspelled. 

Author Response

Dear Reviewer,

We thank you for the comments and help to improve the manuscript.

Accordingly, changes were performed as follows:

  1. We shortened the text in
  • lines 158-160 "Twort, in 1915, observed lysis plates in cultures of Staphylococcus aureus. d'Herelle, as co-discoverer and after observing lysis, in 1917, used Shigella bacteriophages to control dysentery in soldiers" were eliminated.
  • lines 358-361 "E. coli bacteriophages have been the most widely used biological models in history; T4 is the lytic lifecycle model, Lambda is the lysogenic lifecycle model, M13 is the continuous lifecycle model, and ΦX174 is the rolling circle replication model for single-stranded DNA viruses" were eliminated.
