You have reverted all my edits on phagocyte, but note that the article contains some incomplete and misinformation which I try to improve step by step. For example, mast cells are not professionals, osteaclasts are professionals, RBCs are not phagocytes (see 2nd table), mentioning Michel Rabinovitch who invented the terms is important, NK cells and lymphoid cells are also cell-specific phagogytes, etc. By removing these edits, with supporting sources I provided, you reverted them to the wrong information. I wish that you had instead help improve the poor language I used rather than simply sloughing them off. Chhandama (talk) 03:29, 6 March 2019 (UTC)

Hi, I reverted you edits because they did not improve the article. On the contrary, the standard of English was very poor. Osteoclasts (not "osteaclasts" as you have written above) are listed in the table of professional phagocytes in the article. According to Paoletti, R.; Notario, A.; Ricevuti, G., eds. (1997). Phagocytes: Biology, Physiology, Pathology, and Pharmacotherapeutics. New York: The New York Academy of Sciences. ISBN 978-1-57331-102-1, page 427, Table 2, erythrocytes are part of the non-professional phagocyte network. Whether mast cells are considered professional is open to debate and this has been discussed on the article's Talk Page and also see this paper. I do not understand what you mean by natural killer cells and lymphoid cells being cell-specific phagocytes. (You have written "phagogytes" by the way). We would need a source other than Rabinovitch to support the claim that he coined the term "professional phagocyte". Graham Beards (talk) 08:47, 6 March 2019 (UTC)
Thank you for clarifying. But I would concur that RBCs are not phagocytes. I have a hunch – but may be wrong – that the authors of the book you referred to had mistaken the process of RBC removal, which is by phagocytosis in macrophages. And if controversial, mast cells should be in the non-professional section as most sources would support that information. As to Rabinovitch, and NK cells and lymphoid cells as phagocytes, they are discussed in the riview paper I cited. Removing "protists" is also not very informative, as protists can be phagocytosed. Anyway, I do apologise for my slip of fingers – I mean typing mistakes – it has become my natural habit, for shame. Chhandama (talk) 12:03, 6 March 2019 (UTC)
OK. I have removed erythrocytes from the table. I cannot find other reliable sources supporting their inclusion. I have cited two reliable sources to support the professional role of mast cells (Robinson & Babcock 1998, p. 187 and Ernst & Stendahl 2006, pp. 7–10). Given that the term "professional" is in any case not strictly defined, I prefer to leave the text as it is. Lastly, what is the title of the review paper to which you refer?

Macropus phylogenyEdit

I have a couple of queries on the presentation of Macropus at the Tammar article, but should say I know nothing about the genus. Can I trouble you with that? cygnis insignis 18:25, 1 July 2019 (UTC)

Sorry, but I do not know what your are referring too. Graham Beards (talk) 22:28, 1 July 2019 (UTC)
Oh, the Tammar wallaby article, where I think you added a tree and some notes. One query is the description of the subgenus Macropus as sensu stricto, which I take to mean it was redefined at some time. cygnis insignis 23:29, 1 July 2019 (UTC)
That was not me. [1] I drew a tree seven years ago, which is no longer used in the article.Graham Beards (talk) 10:28, 2 July 2019 (UTC)


I confess your comment has confused me. The reference is: Suh A, Brosius J, Schmitz J, Kriegs JO (2013). The genome of a Mesozoic paleovirus reveals the evolution of hepatitis B viruses. Nature Communications. 4: 1791. This refers to the Hep B viruses. It includes a reference to a bird->mammal switch. Since this the article is about Hep B and the section is about its evolution this seems on point to me. If there is an error I would be grateful if you could clarify your remark a little further. Virion123 (talk) 15:27, 24 September 2019 (UTC)

Hepatovirus ( hepatitis A virus) and hepatitis B virus are different viruses. You give me the impression that you think they are the same. Graham Beards (talk) 15:56, 24 September 2019 (UTC)
"Birds may be the original hosts of the 'Hepadnaviridae' with mammals becoming infected after a bird". This is the original statement. Hepadnaviridae while resembling Hepatovirus does not seem to be the same word to me. YMMV. Virion123 (talk) 16:26, 27 September 2019 (UTC)
That was NOT the original statement. You wrote: "Birds may be the original hosts of the Hepatovirus with mammals becoming infected after a bird -> mammal host switch." Here [2] and repeated your error here: [3]. I corrected the error here: [4]. Graham Beards (talk) 17:17, 27 September 2019 (UTC)
