Medline does have an Article with Ferry and House as mentioned but it is a theoretical work. The carbon monoxide pathway was shown earlier by Rother et al. So I'm changing that. Also there is too much focus on one aspect of these bugs so much that this article reads like the abstract of a single research paper instead of an encyclopaedia entry. I'll watchlisted it for now, but I'll look over it in the coming days and append/edit as required.
