[edit] Gram status of Mycobacteria

While it seems odd, members of the genus Mycobacterium are classified as Gram-positive bacteria. I've added an explicit reference to the page (Sherris' Medical Micro), but for online sources, see here, or here, or here, or even at PubMed.

There has been some recent discussion about this G+ve vs. G-ve classification (see PubMed for an example), but at this point the balance of evidence is still in the Gram +ve camp. -- MarcoTolo 01:34, 21 April 2006 (UTC)

I would like to make the suggestion that Mycobacteria are neither Gram negative nor Gram positive (under the heading: Physiology); due to their response to the Gram stain technique. I believe that they should be referred to as acid-fast only. My reference also acknowledges that they stain weakly positive with the Gram stain. I refer to Kumar: Robbins and Cotran: Pathologic Basis of Disease, 7th ed., (2005) Saunders, An Imprint of Elsevier. (Online edition). Tewn 13:02, 18 May 2007 (UTC)

[edit] Too obscure

Phosphatidylmyo-inositol mannosides, any idea on what to do with this? FullMetal Falcon 15:26, 6 November 2006 (UTC)
