One of the major differences between Gram-negative and Gram-positive organisms is the
presence or absence of an outer membrane (Figure 1). In Gram-negative organisms, the …

Staphylococci and most other Gram-positive bacteria incorporate complex teichoic acid (TA)
polymers into their cell envelopes. Several crucial roles in Staphylococcus aureus fitness …

Complex glycoconjugates play critical roles in the biology of microorganisms. Despite the
remarkable diversity in glycan structures and the bacteria that produce them, conserved …

The Staphylococcus aureus multiresistance plasmid pSK1 is the prototype of a family of
structurally related plasmids that were first identified in epidemic S. aureus strains isolated in …

The incorporation of characteristic carbohydrate-based polymers into the cell wall is a
general trait of most Gram-positive bacteria. These cell wall glycopolymers (CWGs) are …

Publisher Summary In the model, Gram-positive organism Bacillus subtilis, the vegetative
cell wall is primarily made up of a thick peptidoglycan layer, proteins, and covalently …
