We know that as more and more bacteria are characterized it may be misleading to refer to bacteria Show more We know that as more and more bacteria are characterized it may be misleading to refer to bacteria as Gram positive or Gram negative.
What if microbiologists started referring more precisely to bacteria as monoderms or diderms to describe the cell envelope architectures? Some bacteria staining Gram positive are actually diderms and some staining Gram negative are actually monoderms. An argument is that cell envlope architecture should relate to phylogenies of various bacterial taxa and help gain insight into the evolution of these architectures. For example: a. Proteobacteria is the largest and most diverse group of species. The phylum contains 5 classes including many gram-negative genera such as E. coli. Also included is Rickettsia an oligate intracellular parasite. b. The Gram positive bacteria are diverse and divided into two phyla: Firmicutes (low GC content) and Mycoplasma which lacks a cel wall. c. Actinobacteria high GC content. May have branch filaments looking like fungus. QUESTION: Does the new nomenclature help microbiologists more accurately categorize the known monumental diversity rather than simply relying on the results of one particular staining technique to being characterization? Does it help clinical microbiologists? Thank you!! Please provide descriptive answer lasting more than a few sentences. Show less
